Check_procs always returns OK

[hbouma]

Running Nagios 5.6.10 on RHEL 7 VMs. Using Test11 as the variable, but in our environment, it really appears as a Java process with the variable =SomeOtherProcess.

Can anyone see what may be happening to cause this to always return a 0 instead of 2?

Code: Select all

check_ncpa.py -H HOST -t SUPERSECRETPASSWORD -M 'plugins/check_procs' -q "args=-aTest11 ' -c 1 '"
PROCS OK: 0 processes with args 'Test11' | procs=0; -c 1 ;;0;

Code: Select all

check_ncpa.py -H HOST -t SUPERSECRETPASSWORD -M 'plugins/check_procs' -q "args=-aTest11 ' -c 1:1 '"
PROCS OK: 0 processes with args 'Test11' | procs=0; -c 1 ;;0;

Code: Select all

check_ncpa.py -H HOST -t SUPERSECRETPASSWORD -M 'plugins/check_procs' -q "args=-a=Test11 ' -c 1 '"
PROCS OK: 0 processes with args 'Test11' | procs=0; -c 1 ;;0;

Code: Select all

check_ncpa.py -H HOST -t SUPERSECRETPASSWORD -M 'plugins/check_procs' -q "args=-a=Test11 ' -c 1:1 '"
PROCS OK: 0 processes with args 'Test11' | procs=0; -c 1 ;;0;

What's the full command-line path of the Java process as it shows up on the RHEL7 server? Please post the output of this command:

Code: Select all

ps -A x -f |grep java

What happens to the output inside Nagios XI if you were to change the check_procs call to only return the number of java processes running? I.e.

Code: Select all

check_ncpa.py -H HOST -t SUPERSECRETPASSWORD -M 'plugins/check_procs' -q "args=-Cjava ' -c 1 '"

./check_ncpa.py -H HOST -t SuperSecretPassword -M 'plugins/check_procs' -q "args=-Cjava ' -c 1 '"
PROCS WARNING: 22 processes with command name 'java' | procs=22; -c 1 ;;0;


PM'd the command line of the java process

If you're testing for a process running the command line, e.g.:

Code: Select all

java -Dweblogic.Name=xxxxxxxxxxx [...]

Then you can use the "check_procs" plugin with args=-aweblogic.Name=xxxxxxxxxxx to test if it's running.

If you want to throw a CRITICAL when the process isn't running, then use this syntax:

Code: Select all

check_ncpa.py -H XXX.XXX.XXX.XXX -t TOKEN -M 'plugins/check_procs' -q "args=-aweblogic.Name=xxxxxxxxxxx 0 0"

Furthermore, you can customize how many matching processes should be running, throw a warning if there's < 2, and a critical if there's < 1:

Code: Select all

check_ncpa.py -H XXX.XXX.XXX.XXX -t TOKEN -M 'plugins/check_procs' -q "args=-aweblogic.Name=xxxxxxxxxxxx -c 1: -w 2:"

Ok, I got it to work with the following format:

check_ncpa.py -H HOST -t SUPERSECRETPASSWORD -M 'plugins/check_procs' -q "args=-aTest11 -c 1:1 "

Please go ahead and remove the servername arguments from your reply if possible. Our IT Security department doesn't want this on the Forum.

Also, you can close this post.
