Using Application Insights to assess general health of Azure Functions
July 15, 2019
To enable monitoring of an Azure Function follow this guide.
Now that monitoring is setup we are able to create queries that allow for some general health monitoring of our Azure Functions.
To get a count of each type of http result code for the last 30 days:
| requests | where timestamp > ago(30d) | |
| | summarize count() by resultCode |
To get the average duration of each function for the last 7 days:
Average duration of operations.txt
| requests | where timestamp > ago(7d) | |
| | summarize count(), min(duration) , max(duration), avg(duration) by operation_Name |
To get the average duration per day of a specific function:
| requests | where name == "OperationName" | | |
| where timestamp > ago(30d) and operation_Name != "" | |
| | summarize avg(duration) by operation_Name, bin(timestamp, 1d) |
