on our rhel server 7.6 version we have the following systemctl service
/etc/systemd/system/test-infra.service
and the value of LimitNOFILE is
systemctl show test-infra.service | grep LimitNOFILE
LimitNOFILE=65535
so I assume the number of open files is max 65535 per this service
is it possible to print the current of open files that are used by this service?
or how to show how many files this service is using?
If you can identify the executable run by this service (in the ExecStart= statement of the test-infra.service file), you should be able to do this using
lsof | grep executable name
possibly followed by | wc -l if you just want to count the files.
