Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

 

Step 2. Access FailOver/Failback recent log files

cat /var/log/app.log | grep DatastoreFailover

The “app.log” file contains the most recent events.

cat /var/log/app.log.0 | grep DatastoreFailover

The “app.log.0” file contains the less recent events.

You can check the presence of older files (e.g. “app.log.1”, “app.log.N”) and access them.

 

Step 3. Decompress and access older log files

gzcat /var/log/app.log.0.gz | grep DatastoreFailover

If you want to access very old log data, you can use this command to decompress and access older log files.

You can check the presence of older files (e.g. “app.log.1.gz”, “app.log.N.gz”), decompress and access them.
