VM Disk space for Azure Log Analytics Agent

Hi
I was looking to see how much (rough) space does a log analytics agent needs on a local machine to store logs.
I have a few Linux VMs with a 30GB OS disk and the Log agent store over 16GB of logs under /var/log/azure. I can definitely go and upgrade the disk but are there any metrics that can identify how much space each extension roughly needs to store its log to plan for the disk upgrade?

Only extension installed right now are:

  1. LinuxDiagnostic | Microsoft.OSTCExtensions.LinuxDiagnostic | 2.*
  2. OmsAgentForLinux | Microsoft.EnterpriseCloud.Monitoring.OmsAgentForLinux | 1.*
  3. SiteRecovery-Linux | Microsoft.Azure.RecoveryServices.SiteRecovery.Linux | 1.*

Thanks

    You might try to rotate the logs if you aren't seeing them clear on their own. Try this - https://github.com/microsoft/OMS-Agent-for-Linux/blob/master/installer/conf/logrotate.conf

    This will change the logs to incremental and auto rotate them.

    You might also look at this thread for other Azure logs that need rotation - https://github.com/Azure/azure-linux-extensions/issues/618
