Known Issue: Usage agent on Linux generates excessive logging related to the Docker monitor daemon (IOJ-2249304)

[#1]

Summary

The usage agent on Linux may generate a large volume of logging messages on computers meeting the following conditions:

• The usage agent is enabled
• The FlexNet inventory agent Docker daemon is not running (for example, because Docker is not installed)

This can result in log files growing over time to be very large.

Details

The following details may appear approximately every 40-90 seconds in the usage agent log (usageagent.log) due to this issue:

[Tue 13 Apr 2021 03:31:21 AM CDT (G, 0)] {4073} Got PerformDockerInventoryScan=False, is running: 5280177...

Repeated messages like the following can also appear in the /var/log/messages file:

Related information

See the following articles for other issues related to usage agent logging:

• Usage agent on Windows generates excessive logging related to the Docker monitor service (IOJ-2181680)
• Usage agent on Unix-like operating systems generates excessive logging related to the "Usage coordinator" (IOJ-2250660)
• usageagent.log does not rotate until usage agent is restarted, potentially leading to a log files growing very large over time (IOJ-2243344)

Fix status

This issue has been fixed in the following FlexNet Manager Suite releases: 2022 R1 (On Premises), 2022 R1 / Apr 2022 (Cloud)
