NRPE Unable to read output

I know I saw this option somewhere before but I just can't find it and my googling is failing me!
I want "Unable to read output" to return with UNKNOWN and not critical. Does that require a recompile of NRPE, or where the heck is that option?

What NRPE version are you on? The latest should behave as you want:
https://github.com/NagiosEnterprises/nr ... 1609-L1612
Code: Select all
} else if (!strcmp(send_buff, "")) {
sprintf(send_buff, "NRPE: Unable to read output\n");
result = STATE_UNKNOWN;
}
Or you can always use
negate:

This is strange - why your check would return CRITICAL? I get "UNKNOWN" with NRPE v. 2.15... as expected.
Code: Select all
[root@localhost ~]# /usr/local/nagios/bin/nrpe -V | grep -i version
Version: 2.15
[root@localhost ~]# /usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c check_users -a '-w 2 -c 5'
NRPE: Unable to read output
[root@localhost ~]# echo $?

Ok, has to be something on my end, maybe I changed it for some reason I know longer remember...who knows. Close this up, I'll investigate on my side, thanks for verifying!
