Storage Account Replication Monitoring

Question

How would we go about being notified that storage account replication is failing or has excessive delays? I see that it's possible to query the date time stamp via powershell, but how do we translate that into an emailed alert?

$lastSyncTime = $(Get-AzStorageAccount -ResourceGroupName <resource-group> -Name <storage-account>
-IncludeGeoReplicationStats).GeoReplicationStats.LastSyncTime

Answer 1

To your point, a simpler solution would be to use Azure Monitor Metrics. Though I do not see replication as a metric at a glance. If this does not work you might try adding it as a custom metric in diagnostic settings. Also, this could be run as an automation runbook or possibly a logic app to log the output or send as an email.

Answer 2

I would do it in azure sentinel. you can create a kql query and generate an alert based on any threshold.
