Nagios core plugin issue

Hello tpa,

So check_ping is working when run from the command line. Is the issue that it's not working in the Web GUI?

Click on the service, open the configure tab, click re-configure service and copy and paste the contents of "Monitor the service with this command:"

Thank you!

Hello tpa,

So check_ping is working when run from the command line. Is the issue that it's not working in the Web GUI?

Click on the service, open the configure tab, click re-configure service and copy and paste the contents of "Monitor the service with this command:"

Thank you!

Hello!

I´m very sorry but I was not able to find the way to do that.
Could you explain me where I can find those commands?

Thank you!

[tacolover101]

From the command line:

Code: Select all

/usr/local/nagios/libexec/check_ping -H localhost -w 1,20% -c 10,40%
sestatus
ls -l /usr/bin/ping

And post the results. Thank you!

Hello!

[root@localhost objects]# /usr/local/nagios/libexec/check_ping -H localhost -w 1,20% -c 10,40%
PING OK - Packet loss = 0%, RTA = 0.10 ms|rta=0.102000ms;1.000000;10.000000;0.000000 pl=0%;20;40;0

[root@localhost objects]# sestatus
SELinux status: disabled

[root@localhost objects]# ls -l /usr/bin/ping
-rwxr-xr-x. 1 root root 62088 Nov 7 2016 /usr/bin/ping

this is strange. your command looks defined fine in the commands.cfg as well. what happens if you try su nagios annd then try to run check_ping? are you still able to?

[bolson]

Are you having this issue with other plugins or only with check_ping. Also, please attach your /usr/local/nagios/etc/nagios.cfg file so we can review. Thank you!

Also, please attach /usr/local/nagios/etc/resource.cfg.
