You can enable diagnostics for migration report runs. When enabled, Unravel creates detailed diagnostic logs and JSON data for each report run. You can locate these diagnostics in a compressed format at the following location:
<Unravel installation directory>/logs/migration_reports/<report_name>
For example, if you are tracking logs for a Cluster Discovery report, you will find the compressed file at
<Unravel installation directory>logs/migration_reports/cluster_discovery/task_entity_140293025757034_2022_04_05-11:48:29_PM.tar.gz
To enable diagnostics for Migration reports, you must set the following properties to true. By default, these properties are disabled or set to false.
Stop Unravel
<Unravel installation directory>/unravel/manager stop
Set the properties for each of the migration reports.
Cluster Discovery
<Unravel installation directory>/unravel/manager config properties set com.unraveldata.migrationplanning.clusterdiscovery.diagnostics true
Cloud Mapping Per Host
<Unravel installation directory>/unravel/manager config properties set com.unraveldata.migrationplanning.cmph.diagnostics true
Workload Fit
Cloud Topology
<Unravel installation directory>/unravel/manager config properties set com.unraveldata.migrationplanning.slicedice.diagnostics true
Heatmap
<Unravel installation directory>/unravel/manager config properties set com.unraveldata.migrationplanning.workload_fit_heatmap.diagnostics true
Services and Versions Compatibility
<Unravel installation directory>/unravel/manager config properties set com.unraveldata.migrationplanning.services_compatibility.diagnostics true
Apply the changes.
<Unravel installation directory>/unravel/manager config apply
Start Unravel
<Unravel installation directory>/unravel/manager start
Following are some samples of the diagnostic logs.
