Microsoft DevOps Engineer Expert AZ-400 Practice Question

Your team needs an operations dashboard that shows the monthly availability of a mission-critical API that is monitored by an Application Insights availability test named "Ping-API". The requirement is to display a single percentage value that represents the ratio of successful test executions to total executions during the last 30 days.

Which Kusto query should you use in an Azure Monitor workbook so the dashboard continuously reflects the correct value?

  • performanceCounters | where counterName == "Requests/Sec" and timestamp > ago(30d) | summarize availability = 100 * avg(counterValue) | render card

  • availabilityResults | where name == "Ping-API" and timestamp > ago(30d) | summarize successRate = 100 * sum(toint(success)) / count() by bin(timestamp, 1h) | render timechart

  • availabilityResults | where name == "Ping-API" | where timestamp > ago(30d) | summarize availability = 100 * sum(toint(success)) / count() | project availability | render card

  • requests | where timestamp > ago(30d) | summarize availability = 100 * (countif(resultCode startswith "2")) / count() | render card
