No such file or directory


Hey all

bit new to Nagios monitoring having taken over the job from someone else so any help here would be appreciated.

Just set up a new Aerospike cluster of 3, and trying to get a few bits monitored in check mk.

followed the read me and got all parts configured, on both boxes, check_nrpe command working ok. NRPE configured to accept commands and arguments.

i can run the following command from the Nagios box

/opt/omd/versions/1.20/lib/nagios/plugins/check_nrpe -H remotehost1 -c aerospike -a free-pct-memory 40 30

and returns a nice

Aerospike Stats - free-pct-memory=99

When i pipe this into the check mk interface it returns (null)

when i change the command to below

define service {

use check_mk_perf,check_mk_default

host_name remotehost1

service_description Aerospike available PCT memory

check_command check_nrpe!aerospike -a free-pct-memory 40 30

active_checks_enabled 1

service_groups Aerospike-Service }

it returns (Return code of 127 is out of bounds - plugin may be missing)

when i execute this on the command line i get the below

-bash: /opt/omd/versions/1.20/lib/nagios/plugins/ No such file or directory

that is running any variation of


even without any arguments after so im guessing the problem lies on the Nagios box itself.

i was wondering if anyone has come across this problem before?

if you require more information please let me know
