Hi @Bombbe ,
I have tried to reproduce the issue but was able to see Suspended state jobs in AzureDiagnostics kusto table in LAW (Log Analytics Workspace). In past there was a similar case that only affected child jobs on Update Management i.e., Patch-MicrosoftOMSComputer jobs only and all other suspended jobs would be showing the suspended status in Log Analytics AzureDiagnostics table. In that case, as a workaround, below query worked as expected and returned the expected results. Also, for resolution of the issue, product engineering team has identified the bug and has provided the fix.
AzureDiagnostics
| where ResourceType contains "AUTOMATION"
| where (ResultDescription contains "Suspended" and ResultType == "In Progress") or (ResultType == "Failed") or (ResultType == "Suspended")
| parse ResultDescription with * 'JobId=' JobId '] to be ' Status '. Status will be discovered from exception.' *
| summarize max(TimeGenerated) by RunbookName_s, JobId_g, ResultType, ResultDescription, ChildJobId = JobId, Status
See if your issue is similar to it. If not, to try diagnosing and troubleshooting the cause of this kind of issue, it would require deep dive with the help of related environment trace logs, etc. So for that, I would recommend to raise a technical support request if you have a support plan. But if you don't have a support plan then please send an email to AzCommunity@microsoft.com with subject being "Attn:Krishna" and your subscription ID and this question's link in the body of the email so that my team will work with you via our technical support channel.
