Summary
When the FlexNet inventory agent is configured to gather Docker inventory, the fnms-docker-monitor process will produce and save an inventory .ndi file once for each container image that is ever found on the host. This is done to minimize container inventory gathering activity. However it also has the effect that inventory files will tend to accumulate in the /var/opt/managesoft/tracker/inventories directory, potentially leading to a significant number of files being retained on hosts which have had a large number of container images over time.
Mitigation
Old files in the /var/opt/managesoft/tracker/inventories directory can be safely deleted to reduce the number of files that are retained.
For example, this may be achieved by executing a UNIX command similar to the following to find and delete cached inventories files that are older than 7 days:
find /var/opt/managesoft/tracker/inventories -type f -mtime +7 -print0 | xargs -0 rm
Fix status
This issue has been fixed in the following FlexNet Manager Suite releases: 2021 R1 (On Premises), 2021 R1 / Jul 2021 (Cloud)
