Monitor

This problem is probably as old as there are monitoring tools on the market. “How can I exclude legitimately deallocated VMs from alerting” is a question that I’ve heard many times.

Every once in a while you might need to create an alert which runs a Log Analytics or Application Insights query. When designing the alert you need to define some attributes: the query, the time period, the frequency and the threshold.

A customer of mine had the following rule configured: It was his expectation that this rule would be triggered when in the last five minutes at some point more that 200 requests/s were being made to the App Service. Unfortunately this is not the case. The rule will sum the number of requests for the last five minutes and if that number is > 200 the rule will trigger.

If you are archiving diagnostic logs or activity logs to a storage account through Azure Monitor be aware that on Nov 1, 2018 there will be a breaking change in the format.

When using Azure Backup to manage (geo-)distributed backups across a company you may find that the Azure Backup Reports with Power BI is limited to a single storage account. Unfortunately the reporting telemetry coming from Azure Backup needs to be written to a storage account that is in the same region as the Recovery Services Vault.

Change tracking covers software installation, changes to services, daemons, Registry and the file system. This is available for both cloud based (Azure, AWS, GCP), on-premises and service provider hosted systems (given network connectivity to Azure).

Nearly every customer I talk to about Azure management asks me this: “How can I do process monitoring?”. As there is currently no way to directly instrument either the Windows or the Linux agent to do explicit process monitoring another way need to be found.
