Configure the GCE instance

Disable selinux.
```
sudo setenforce Permissive
```
Edit /etc/selinux/config to ensure the setting persists after reboot and ensure SELINUX=permissive.
```
sudo vi /etc/selinux/config
```
Install libaio.x86_64, lzop.x86_64, and ntp.x86_64.
```
sudo yum install -y libaio.x86_64
sudo yum install -y lzop.x86_64
sudo yum install -y ntp.x86_64
```
If you are using Unravel-managed MySQL or MariaDB, run sudo yum install numactl-devel.x86_64 command. Also refer to Integrating Database.
Set vm.max_map_count to 262144
Set nproc limit to unlimited.
Add unravel.conf file with the following settings to /etc/security/limits.d:
```
unravel    soft  nproc unlimited
```
Start ntpd and check the system time.
```
sudo service ntpd start
sudo ntpq -p
```
Create a new Unravel user, which should not be a root user. For example:
```
sudo useradd unravel
```

2. Download Unravel

Download Unravel onto the VM instance that you have created.

Important

Before downloading Unravel for your platform, ensure to get the username and password from Unravel Support.

Download the Unravel package (RPM or Tar):

You can refer to Download section for the complete list of Unravel product downloads.

For example:

Tar

curl -v https://preview.unraveldata.com/unravel/RPM/4.7.x/unravel-4.7.x.x-cloud.tar.gz -u username:password

RPM

curl -v https://preview.unraveldata.com/unravel/RPM/4.7.x/unravel-4.7.x.x.rpm -o unravel-4.7.x.x.rpm -u username:password

3. Deploy Unravel

Deploy Unravel on the GCP instance that you have created.

Unravel binaries are available as a tar file or RPM package. You can deploy the Unravel binaries in any directory on the server. However, the user who installs Unravel must have the write permissions to the directory where the Unravel binaries are deployed.

After deploying the Unravel binaries, the directory layout for the Tar and RPM will be unravel/versions/<Directories and files>. The binaries are deployed to <Unravel_installation_directory>, and Unravel will be available in <Unravel_installation_directory/unravel.

The following steps to deploy Unravel from a tar file should be performed by a user who will run Unravel.

Create an Installation directory.
```
mkdir /path/to/installation/directory
```
For example: mkdir /opt/
Extract Unravel tar file to the installation directory, which you have created in the first step. After you extract the contents of the tar file, unravel directory is created within the installation directory.
```
tar zxf unravel-<version>tar.gz -C /path/to/installation/directory
```
For example: tar zxf unravel-4.7.x.x.tar.gz -C /opt
The unravel directory will be available within /opt
Grant ownership of the directory to a user who will run Unravel.
```
chown -R username:groupname /opt/unravel/
```
For example: chown -R hadoop:hadoop /opt/unravel/

Important

A root user should perform the following steps to deploy Unravel from an RPM package. After the RPM package is deployed, the remaining installation procedures should be performed by the Unravel user.

Create an installation directory.
```
mkdir /usr/local/unravel
```
Run the following command:
```
rpm -i unravel-<version>.rpm
```
For example: rpm -i unravel-4.7.0.0.rpm
The unravel directory will be available in /usr/local
If you want to provide a different location, use the --prefix command. For example:
```
mkdir /opt/unravel
rpm -i unravel-4.7.0.0.rpm --prefix /opt
```
The unravel directory will be available in /opt.
Grant ownership of the directory to a user who will run Unravel. This user executes all the processes involved in Unravel installation.
```
chown -R username:groupname /usr/local/unravel
```
For example: chown -R hadoop:hadoop /usr/local/unravel
Continue with the installation procedures as unravel user.

4. Install Unravel

You can also manually install Unravel, Refer to Run setup

The Interactive Precheck utility is run to validate the required configurations before installing Unravel. When you run the Interactive Precheck utility, various checks are prompted for gathering configuration information. The responses you provide for these checks generate a bootstrap configuration file. This file, which contains the configuration information, is then used to install Unravel.

Do the following to install and configure Unravel with Interactive Precheck.

After you download and deploy the Unravel, run the precheck.sh script from unravel/versions/X.Y.Z/healthcheck/.
For example:
/opt/unravel/versions/X.Y.Z/healthcheck/precheck.sh

Enter the necessary details when you are prompted for the following configuration information:

This section covers general information about your Unravel install. You are prompted for the following:

Data platform you want to monitor.
For Hadoop: type of Unravel node you want to configure.
For edge nodes: core node location and test connectivity.

You must answer the following prompts:

-- General information
Which data platform are you installing for?
   1- Hadoop
   2- EMR
   3- HDI
   4- Databricks
   5- Dataproc
   6- BigQuery

Select one of the above [Hadoop]: 

## You can choose a number corresponding to the platform.

This check lets you select a method that can be used to get data from BigQuery. You can choose either the Pull method or the Push method.

Tip

Unravel recommends the Pull method, which is more secure.

For this check, you must answer the following prompts:

-- BigQuery
Do you want Unravel to pull data from BigQuery? (yes=pull, no=push) (y/n)

Pull method: Type yes to use the Pull method. In case you leave it empty also, the pull method is used by default.
```
-- BigQuery
Do you want Unravel to pull data from BigQuery? (yes=pull, no=push) (y/n) [Yes]: yes
```
The polling time to pull data from BigQuery is set to 300 seconds (5 mins) by default. You can change this time separately after installation by running the manager config set-polling command:
For example:
```
/opt/unravel/manager config bigquery set-polling 100 
```
Refer to Set polling period for BigQuery pull method for detailed instructions.
Caution
When you use the Pull method, there is some delay for the BigQuery jobs to be displayed on the Unravel UI compared to the Push method, where the BigQuery jobs are displayed in real-time.
Push method: Type no, to use the Push method. You are prompted to enter the LR endpoint and the LR port, where data can be pushed from BigQuery. 4443 is the default LR port, which can be changed.
```
-- BigQuery
Do you want Unravel to pull data from BigQuery? (yes=pull, no=push) (y/n) [Yes]: no
Log receiver fully qualified hostname [None]: <lr-endpoint>
Log receiver port (integer) [4443]: <lr-port>
```
Note
Also, refer to 7. Configure an HTTPS Load Balancer for Unravel Endpoint

After you have installed Unravel for BigQuery, run the following command to verify the method you have set to get data from BigQuery.

<Unravel installation directory>/unravel/manager config bigquery show

The results will reflect the method used in the Mode field. For example:

/opt/unravel/unravel/manager config bigquery show
-- Running: config bigquery show
BigQuery support: Enabled
LR endpoint: Default
Mode: pull	
No project configured.

This check allows you to configure database-related information and an external database for Unravel.

5. Run the CURL command to fix a known issue

You can encounter a NoIndexFound exception for fresh installations of Unravel on GCP-BigQuery. This is a known issue in Unravel version 4.7.7.0. As a workaround for this issue, you must run the following CURL command on the Unravel node after the installation:

curl -XPUT http://localhost:4171/app-19700101_07

6. Enable Transport Layer Security (TLS) for Unravel UI

Refer to Enabling Transport Layer Security (TLS) for Unravel UI.

7. Configure an HTTPS Load Balancer for Unravel Endpoint

Note

The HTTPS load balancer for Unravel endpoint must be configured only when using the Push model.

Unravel LR endpoint should be available over a publically accessible HTTPS endpoint to receive messages from BigQuery PubSub. The Load Balancer is an easier and more secure method to push the log messages between the Google Cloud Platform (GCP) and Unravel. Use the following instructions to configure an HTTPS load balancer for Unravel with public endpoint and SSL termination.

You must have the following information handy before you configure the Load Balancer:

Region and Zone where the Unravel VM is running.
Network and Subnet-network where the Unravel VM is running.
A valid SSL certificate in GCP.

Do the following to create a Load Balancer

Create an instance group. Refer to Create a managed instance group for detailed instructions.
- In the New unmanaged instance group page, ensure to keep the following items the same as that of Unravel VM.
  - Location > Region
  - Location > Zone
  - Network and Instances > Network
  - Network and Instances > SubNetwork
- Under Port Mapping, enter the following:
  - Port Name: http4043
  - Port Number: 4043
Set up an HTTPS Load Balancer. Refer to Set up an HTTPS Load Balancer for detailed instructions. Ensure to do the following:
- Under Name, update the name as unravel-loadbalancer.
- In Backends > New Backend > Instance groups, select the Unravel instance group that you had created in Step 1.
- Under Health check, do the following:
  - Select Create a health check, and then add the name as unravel-4043-hc
  - Update the Protocol as HTTP and Port as 4043.
  - Update the Request Path as /lr/status.
- Ensure that Port is set to 443 to allow HTTPS traffic.
After the Load Balancer is created, find the public IP address of the Load Balancer that is mentioned under Frontend section of the Load Balancer. Add the IP address of the Load Balancer to a valid DNS name.

8. Set up Unravel to receive BigQuery data automatically

Unravel can be set up to automatically create and configure resources in more than 100 projects at a time. You can either add single projects or multiple projects at a time for Unravel monitoring. These projects can be added either with customer-supplied credentials or with Unravel-generated credentials.

You must separately configure the BigQuery projects that you want to track from the Data page. The Data page on Unravel UI can show data for only up to 100 BigQuery projects.Data

Unravel ships the following resources, which are required to automatically set up Unravel to receive BigQuery data.

Terraform
Open-source software for infrastructure provisioning.
gcloud CLI
Set of tools to create and manage Google Cloud resources.

Note

You can also manually set up Unravel to receive BigQuery data. Refer to Set up Unravel to receive BigQuery data

Before you set Unravel to receive BigQuery data

BigQuery projects can be set in Unravel using either one of the following:

Unravel-generated credentials
Customer-supplied credentials

For projects added with Unravel-generated credentials, all the resources are created and handled by Unravel. However, for the customer-supplied credentials, you must create and provide all the resources.

Ensure to have the following handy before you add the projects:

Google account with required IAM role permissions for gcloud CLI authentication
IAM role permissions for gcloud CLI authentication
The Google account used to authenticate with gcloud CLI must have the following permissions to create and delete resources on GCP for tracking BigQuery. These permissions fit into the security principle of least privilege , which means that these are the only permissions required to get the job done. If you do not have the following permissions, the Terraform script will not run properly.
Important
The IAM role permissions should be for every project the Google account user wants to integrate with Unravel.
iam.roles.create
iam.roles.delete
iam.roles.get
iam.roles.undelete
iam.roles.update
iam.serviceAccountKeys.create
iam.serviceAccountKeys.delete
iam.serviceAccountKeys.get
iam.serviceAccounts.create
iam.serviceAccounts.delete
iam.serviceAccounts.get
iam.serviceAccounts.getIamPolicy
iam.serviceAccounts.setIamPolicy
logging.sinks.create
logging.sinks.delete
logging.sinks.get
pubsub.subscriptions.create
pubsub.subscriptions.delete
pubsub.subscriptions.get
pubsub.topics.attachSubscription
pubsub.topics.create
pubsub.topics.delete
pubsub.topics.get
pubsub.topics.getIamPolicy
pubsub.topics.setIamPolicy
resourcemanager.projects.get
resourcemanager.projects.getIamPolicy
resourcemanager.projects.setIamPolicy
Execute the following commands from the Google Cloud shell to automate the creation of a role and bind it to the user.
Run the following to create the role.
gcloud iam roles create UnravelGoogleAuthRole --organization=<your-org-id-in-gcp> --title=UnravelGoogleAuthRole --description="Creation of role in GCP on an organization level for automated integrating bigquery projects with Unravel" --permissions=iam.roles.create,iam.roles.delete,iam.roles.get,iam.roles.undelete,iam.roles.update,iam.serviceAccountKeys.create,iam.serviceAccountKeys.delete,iam.serviceAccountKeys.get,iam.serviceAccounts.create,iam.serviceAccounts.delete,iam.serviceAccounts.get,iam.serviceAccounts.getIamPolicy,iam.serviceAccounts.setIamPolicy,logging.sinks.create,logging.sinks.delete,logging.sinks.get,pubsub.subscriptions.create,pubsub.subscriptions.delete,pubsub.subscriptions.get,pubsub.topics.attachSubscription,pubsub.topics.create,pubsub.topics.delete,pubsub.topics.get,pubsub.topics.getIamPolicy,pubsub.topics.setIamPolicy
For example:
gcloud iam roles create UnravelGoogleAuthRole --organization=592556919173 --title=UnravelGoogleAuthRole --description="Creation of role in GCP on an organization level for automated integrating bigquery projects with Unravel" --permissions=iam.roles.create,iam.roles.delete,iam.roles.get,iam.roles.undelete,iam.roles.update,iam.serviceAccountKeys.create,iam.serviceAccountKeys.delete,iam.serviceAccountKeys.get,iam.serviceAccounts.create,iam.serviceAccounts.delete,iam.serviceAccounts.get,iam.serviceAccounts.getIamPolicy,iam.serviceAccounts.setIamPolicy,logging.sinks.create,logging.sinks.delete,logging.sinks.get,pubsub.subscriptions.create,pubsub.subscriptions.delete,pubsub.subscriptions.get,pubsub.topics.attachSubscription,pubsub.topics.create,pubsub.topics.delete,pubsub.topics.get,pubsub.topics.getIamPolicy,pubsub.topics.setIamPolicy,resourcemanager.projects.get,resourcemanager.projects.getIamPolicy,resourcemanager.projects.setIamPolicy
Bind the role to a user.
gcloud organizations add-iam-policy-binding <your-org-id-in-gcp> --member='user:<user account>' --role='organizations/<unravel-organization-ID>/roles/UnravelGoogleAuthRole'
For example:
gcloud organizations add-iam-policy-binding 592556919173 --member='user:user@unraveldata.com' --role='organizations/592556919173/roles/UnravelGoogleAuthRole'
Project ID file in case you are integrating multiple projects at a time with Unravel.
Project ID text file
You can configure multiple projects with customer-supplied credentials. To implement this, you must create a text file containing the list of project IDs and provide the path of this file during integration. Each line in the text file must carry a single Project ID.
For example:
```
project-id-011
project-id-012
project-id-013
project-id-014
project-id-015
project-id-016
project-id-017
project-id-018
project-id-019
project-id-020
```
Customer-supplied credential files in case you are integrating projects using customer-supplied credentials.
Customer-supplied credentials directory
Each project, which you want to add for monitoring, must have a corresponding credentials file in the credentials directory with the same project ID and .json extension.
Important
The credentials file should have the same name as the project ID.
For example, you have the project-id-file with the following project IDs:
```
first-project
second-project
```
then the credential files in the credentials directory should have the service account keys JSON file as follows:
```
first-project.json
second-project.json
```
Log Receiver (LR) endpoint
This is required only when you are adding projects.
Subscription ID (Optional)
The subscriber ID that you want to configure with a pub/sub topic. This is optional. If this is not provided then the default subscription ID unravel-bigquery-sub is considered.
Note
If you have created the resources on GCP, then the Subscription ID is mandatory.

Setup Unravel to automatically configure BigQuery projects for Unravel monitoring

Stop Unravel.

<Unravel installation directory>/unravel/manager stop

Set the Log Receiver (LR) endpoint. This step is required only if you are using customer-supplied credentials to add the projects.
Important
Ensure that the LR end point supports HTTPS.
```
<Unravel installation directory>/unravel/manager config bigquery set-lr-endpoint <host> <port>
```
For example: /opt/unravel/manager config bigquery set-lr-endpoint myhostname.unraveldata.com 1234
Run <Unravel installation directory>/unravel/manager config bigquery show to verify. The following output is shown
```
— Running: config bigquery show
BigQuery support: Enabled
LR endpoint: https://myhostname.unraveldata.com:1234
No project configured.
```
Add BigQuery projects.
Configure the BigQuery projects that you want to be monitored by Unravel. Single or multiple BigQuery projects can be added for monitoring. You can configure the projects either with the customer-supplied credentials or with Unravel-generated credentials.
Also, refer to Remove BigQuery projects from Unravel
Add a single BigQuery project with customer-supplied credentials
When you configure a single project with customer-supplied credentials, the credentials in the file are copied and encrypted.
Note
For customer-supplied credentials, you must configure the target endpoint of the Pub/Sub subscription ID to unravel the LR HTTPS endpoint.
To add a single BigQuery project for Unravel monitoring with customer-supplied credentials, do the following:
Using a terminal, run the following command from the Unravel installation directory:
```
<Unravel installation directory>/unravel/manager config bigquery add <project-id> <subscription-id> <path/to/credentials-file>
```
For example:
/opt/unravel/manager config bigquery add my-project subscription-12345 /credentials/unravel.json
Note
You can use the same command to add more projects one at a time. If you use the same project ID, the existing project gets updated.
Add a single BigQuery project with Unravel-generated credentials
Unravel can automatically create the appropriate resources and generate the credentials required to monitor BigQuery projects. To add a single BigQuery project for Unravel monitoring with Unravel managed credentials, do the following:
Using a terminal, run the following command from the Unravel installation directory:
```
<Unravel installation directory>/unravel/manager config bigquery add <project-id> <subscription-id> --create-credentials
```
For example:
/opt/unravel/manager config bigquery add my-project subcription-12345 --create-credentials
Add multiple BigQuery projects using customer-supplied credentials
You can configure multiple projects with customer-supplied credentials. To implement this, you must create a text file containing the list of project IDs and provide the path of this file in the following command. Each line in the text file must carry a single Project ID. Along with the project ID, you must also provide the subscription ID and the path to the customer-supplied credentials file. During the configuration, the credentials in the file are copied and encrypted.
Run the following command, to add multiple BigQuery projects for Unravel monitoring with customer-supplied credentials.
<Unravel installation directory>/unravel/manager config bigquery add --batch </path/to/project-id-file> [--subscription-id <sub>] --credentials <path/to/credentials-folder>
--subscription-id : This is an optional field when you add projects with Unravel-generated credentials. If you do not provide any value, the default unravel-bigquery-sub is considered.
Note
The --subscription-id is a mandatory field when you add projects with customer-supplied credentials since there is a different subscription ID.
</path/to/project-id-file>: The full path to the directory containing the project IDs.
<path/to/credentials-folder>: The full path to the directory containing the credentials files.
Each project must have a corresponding credentials file in the credentials directory, with the same name as that of the project ID and the .json extension.
Important
The credentials file should have the same name as that of project ID.
For example, you have the project-id-file with the following project IDs:
first-project second-project
then the credential files in the credentials directory should be named as follows:
first-project.json second-project.json
For example, you have a list of projects in project-id-file with a subscription ID as a-sub-id and your credentials file for each of the projects is listed in credentials-directory. Run the following command to add multiple projects with customer-supplied credentials:
manager config bigquery add --batch /opt/unravel/project-id-file --subscription-id a-sub-id --credentials /opt/unravel/credentials-directory
Run <Unravel installation directory>/unravel/manager config bigquery show to verify. The following output is shown:
$ /opt/unravel/manager config bigquery show -- Running: config bigquery show BigQuery support: Enabled LR endpoint: https://myhost.unraveldata.com:1234 Project: first-project credentials_file: /opt/unravel/data/conf/bigquery/credentials/first-project.json datapage: true subscription_id: a-sub-id Project: second-project credentials_file: /opt/unravel/data/conf/bigquery/credentials/second-project.json datapage: true subscription_id: a-sub-id Datapage projects: 2 out of 100. — Ok
Add multiple BigQuery projects with Unravel-generated credentials
Unravel can automatically create resources on the GCP side and generate the credentials required to monitor BigQuery projects.
Run the following command to add multiple BigQuery projects for Unravel monitoring with customer-supplied credentials:
<Unravel installation directory>/unravel/manager config bigquery add --batch </path/to/project-id-file> [--subscription-id <sub>] --create-credentials
Note
</path/to/project-id-file>: The full path to the directory containing the project IDs.
--subscription-id : This is an optional field. If you do not provide any value, the default unravel-bigquery-sub is considered.
For example, you have a list of projects in project-id-file with a subscription ID as a-sub-id. Run the following command to add multiple projects with Unravel-generated credentials:
manager config bigquery add --batch /opt/unravel/project-id-file --subscription-id a-sub-id --create-credentials
Run <Unravel installation directory>/unravel/manager config bigquery show to verify. The following output is shown:
$ /opt/unravel/manager config bigquery show -- Running: config bigquery show BigQuery support: Enabled LR endpoint: https://myhost.unraveldata.com:1234 Project: first-project credentials_file: /opt/unravel/data/conf/bigquery/credentials/first-project datapage: true integration: true subscription_id: a-sub-id Project: second-project credentials_file: /opt/unravel/data/conf/bigquery/credentials/second-project datapage: true integration: true subscription_id: a-sub-id Datapage projects: 2 out of 100. — Ok

Add projects to Data page.

You must separately configure the BigQuery projects that you want to track from the Data page. The Data page on Unravel UI can show data for only up to 100 BigQuery projects.Data

Also, refer to Remove BigQuery projects from Data page on Unravel UI.

To add single projects to Data page, run the following:
```
<Unravel installation directory>/unravel/manager config bigquery enable-datapage <project-id>
```
For example: /opt/unravel/manager config bigquery enable-datapage myproject
To add multiple projects to Data page, run the following:
```
<Unravel installation directory>/unravel/manager config bigquery enable-datapage --batch </path/to/project-id-file> 
```
For example: /opt/unravel/manager config bigquery enable-datapage --batch /opt/unravel/project-id-file

Run <Unravel installation directory>/unravel/manager config bigquery show to verify if the project IDs are enabled for Data page. The following sample output is shown:

$ /opt/unravel/manager config bigquery show
— Running: config bigquery show

BigQuery support: Enabled
LR endpoint: https://myhost.unraveldata.com:1234
Project: project-id-file
integration: true
subscription.id: a-sub-id

Project: first-project
credentials.file: /opt/unravel/data/conf/bigquery/credentials/first-project
subscription.id:  a-sub-id

Project: second-project
credentials.file: /opt/unravel/data/conf/bigquery/credentials/second-project
subscription.id:  a-sub-id

Datapage projects: 2 out of 100

Integrate BigQuery projects for Unravel monitoring. This is a mandatory step for Unravel-generated credentials.
Note
When the following command is run, you can configure all the projects added for Unravel monitoring at once i.e projects with customer-supplied credentials as well as with Unravel managed credentials.
```
<Unravel installation directory>/unravel/manager config bigquery integrate
```
A URL will be provided in the output.
Note
If you want to skip the interactive gcloud authentication by Unravel and handle the gcloud authentication on your own, then run the command as follows:
```
<Unravel installation directory>/unravel/manager config bigquery integrate --skip-authorization
```
Authenticate gcloud CLI.
1. On a Google Chrome browser, copy the URL provided in the output, and in the sign-in dialog box, click Allow. Ensure to sign in to the gcloud CLI from the account that is authenticated with the required permissions.
2. From the Sign in to the glcoud CLI box, click Copy button to copy the authorization code.
3. Go back to the terminal and paste the authorization code in the Enter authorization code field and press ENTER. This will run the following actions in the background:
  - Authenticate the user with Google Cloud.
  - Configure the required resources on the GCP.
  - Encrypt the credentials (service account keys) and then integrate them with Unravel.
  - Integrate all the added BigQuery projects with Unravel.
  - Securely sign out the end user from the gcloud session.
