In the Windows Admin Center, I enabled Azure Monitor for a number of servers and added an alert rule "Heartbeat" in Windows Admin Center. I noticed that this alert rule does work in some cases but also doesn't do much in many other cases.
The rule is visible in the Azure Log Analytics workspace.
| Schedule | Heartbeat from Windows Admin Center | |
| Frequency in minutes | 5 | |
| Time window in minutes | 5 | |
| Query | Heartbeat | summarize numberOfHeartbeats = count(Computer) by Computer | where numberOfHeartbeats < 2 | |
| | | |
| Time | Event | Result |
| 9:31 | Server crash (shutdown) | |
| 9:32 | Heartbeat schedule | No alert |
| 9:33 | | |
| 9:34 | | |
| 9:35 | | |
| 9:36 | | |
| 9:37 | Heartbeat | No alert |
| | | |
| Time | Event | Result |
| 9:58 | Server1 crash (shutdown) | |
| 9:59 | | |
| 10:00 | | |
| 10:01 | | |
| 10:02 | Heartbeat schedule | |
| 10:03 | | Alert Server1 |
| | | |
| Time | Event | Result |
| 10:17 | Heartbeat schedule | No alert |
| 10:18 | | |
| 10:19 | Server1 crash (shutdown) | |
| 10:20 | Server2 crash (shutdown) | |
| 10:21 | Server3 crash (shutdown) | |
| 10:22 | Heartbeat schedule | No alert |
| 10:23 | | |
| 10:24 | | |
| 10:25 | | |
| 10:26 | | |
| 10:27 | Heartbeat schedule | No alert |
Anyone with the same experience?
