If you're running version 3.20 of nrpe this is a known issue related to SSL. The issue will be fixed in NRPE v. 3.21

This looks like a permissions issue, or your plugin cannot file a file it is looking for, can you run
Code: Select all
ls -al /home/user/Downloads/apache-cassandra-3.11.0/bin/nodetool

Can you run the command as the nagios user on the remote server? (This is the command you added to the nrpe.cfg)
Code: Select all
su nagios -c "/path/to/plugin -args"
