Based on the log provided, looks like you are trying to query AzureActivity table from Log Analytics Workspace (LAW) but output it gives is no new results. One observation is, it is INFO but not ERROR log level so I assume that you have already configured sending activity logs to LAW in either of two ways i.e., via Activity logs diagnostics settings or via legacy method.
- If yes, I would recommend to check by manually querying AzureActivity table from logs tile of LAW and see if you get the output.
- If no, I would recommend to configure sending activity logs to LAW as mentioned above and then manually query AzureActivity table from logs tile of LAW and see if you get the output.
On the other hand, if you can provide more context or your exact use case then it would be helpful to answer or diagnose and troubleshoot the issue in a better way.
In that regards, below are few questions:
- When you say "thus no logs are shown in our siem", did you configure sending logs from LAW to some siem? If yes, what are the high level steps that have followed to do it?
- When you say "integrate Microsoft Azure log analytics", what do you mean by integrate? Did you integrate LAW with some other Azure resouce? If yes, more information would be helpful.
- Based on the log format, I believe its from a log file. If yes, what is the location of the log file.
Glad to know that now you are receiving data from log analytics and it is working fine now.
