I'm trying to create a custom metric alert based on some metrics in my Application Insights logs. Below is the query I'm using;
let start = customEvents
| where customDimensions.configName == "configName"
| where name == "name"
| extend timestamp, correlationId = tostring(customDimensions.correlationId), configName = tostring(customDimensions.configName);
let ending = customEvents
| where customDimensions.configName == configName"
| where name == "anotherName"
| where customDimensions.taskName == "taskName"
| extend timestamp, correlationId = tostring(customDimensions.correlationId), configName = tostring(customDimensions.configName), name= name, nameTimeStamp= timestamp ;
let timeDiffs = start
| join (ending) on correlationId
| extend timeDiff = nameTimeStamp- timestamp
| project timeDiff, timestamp, nameTimeStamp, name, anotherName, correlationId;
timeDiffs
| summarize AggregatedValue=avg(timeDiff) by bin(timestamp, 1m)
When I run this query in Analytics page, I get results, however when I try to create a custom metric alert, I got the error Search Query should contain 'AggregatedValue' and 'bin(timestamp, [roundTo])' for Metric alert type
The only response I found was adding AggregatedValue
which I already have, I'm not sure why custom metric alert page is giving me this error.
