Logs continue to appear in the SIEM destination even though the corresponding appnames are configured in the log forwarding exclusion filter.
Log volume remains high for excluded appnames (e.g., osfsd, envoy-access, localcli).
Logs may contain keywords related to system health and performance monitoring.
Filter conditions appear correct but do not drop the targeted application logs.
Environment
Aria Operations for logs 8.18.x
Cause
The issue is caused by a configuration syntax error within the log forwarding exclusion filter. An unintended wildcard character (*) was added before the appnames in the exclusion list (e.g., *osfsd instead of osfsd). This extraneous character breaks the filter syntax and prevents it from matching the incoming application logs.
Resolution
Remove the unintended wildcard character from the affected appnames:
Navigate to Log management > Log forwarding.
Edit the specific log forwarding instance.
Review the exclusion filters and remove any extraneous wildcard characters (*) from the beginning of the appnames.
Save the configuration.
Monitor the SIEM destination for 15-30 minutes to verify logs are being successfully excluded.
