Nagios Support Forum

Is it all working now? There wasn't a /usr/local/nagiosxi/var/cmdsubsys.log attached. If you change'd the cron tab back, then the log file is overwritten unless you saved it off somewhere. The apply configs should show up in the log. One thing you could do is just tail -f /usr/local/nagiosxi/var/cmdsubsys.log and then run an apply config. It won't be in the log file permanently, but you could send the output of the tail command.

What do I do to get plugins working again?

I am sending the output from tailing /usr/local/nagiosxi/var/cmdsubsys.log and running Apply Configuration with security off:

te(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /usr/local/nagiosxi/html/includes/utils-auditlog.inc.php on line 95

Thanks.

we tried to add our client disks just from one client and the first one worked and the second one did not.

client services file looks like:

define service {
host_name <Client Hostname>
service_description / Disk Info
use generic-service
check_command check_nrpe!check_hda1!-a '-w 20% -c 10% -p /dev/mapper/sysvg-lv_root'!!!!!!
register 1
}

define service {
host_name <Client Hostname>
service_description /home Disk Info
use generic-service
check_command check_nrpe!check_hda2!-a '-w 20% -c 10% -p /dev/mapper/sysvg-lv_home'!!!!!!
register 1
}

the nagiosql.tbl_service table was updated but the nagios.nagios_services did not???

hda1 works and hda2 doesn't work with an error check_disk undefined. Also under adding commands when run check command both disk commands work???

In your output from the cmdsubsys.log file looks like the time is not set correctly on the server so follow through this document to setup the time and time zone on the server.

This error
hda1 works and hda2 doesn't work with an error check_disk undefined. Also under adding commands when run check command both disk commands work???
is probably caused be the check_hda2 command is not defined in the NRPE Agent on the remote server.
Take a look at the nrpe.cfg file on the remote server and either define an hda2 command or setup a generic check_disk command and use that instead.
Here is an example check_disk command for the nrpe.cfg file Remember, after doing any changes to the nrpe.cfg file, you will have to restart the nrpe agent.


Then you would change your check_command from to Save it and that should use the generic check_disk command defined on the remote system.

Our Timezone is fine:

From Console System Settings:

Our timezone is fine.

For the disk monitoring we will try what you suggested. Thanks.

There error is specifically about date.timezone in /etc/php.ini, which you didn't give us. It's on page 4 of that time document. PHP thinks you are in UTC, according to the error. Whether that is due to /etc/php.ini not being set, or for some other reason, it's hard to know right now.

We've also seen a lot of problems with time on RHEV specifically. Does the output of hwclock match the output of date?

It also says you aren't NTP synchronized, which is a little bit suspicious, but might be ok.

Ok that didn't work, we still get "NRPE: Command 'check_disk' not defined" Nagios Web UI whereas when we run from the command line its working fine.
/usr/local/nagios/libexec/check_nrpe -H xx.xx.xx.xx -c check_disk -a '-w 20% -c 10% -p /dev/mapper/sysvg-lv_home'
DISK OK - free space: /home 7217 MB (95.89% inode=100%);| /home=308MB;6348;7141;0;7935
From the nagios server where the service for remote host we are monitoring disk is defined.
define service {
host_name xxxxxxx
service_description /home Disk Usage
use xiwizard_nrpe_service
check_command check_nrpe!check_disk!-a '-w 20% -c 10% -p /dev/mapper/sysvg-lv_home'!!!!!!
max_check_attempts 5
check_interval 5
retry_interval 1
check_period xi_timeperiod_24x7
notification_interval 60
notification_period xi_timeperiod_24x7
contacts nagiosadmin
_xiwizard linux-server
register 1
}
This is what we have in the nrpe.cfg file of both nagios server and remote host:

command[check_disk]=/usr/local/nagios/libexec/check_disk $ARG1$

In MySQL -- nagiosql.tbl_service table is being updated but nagios.nagios_services is NOT updating is it suppose too?

Thanks

I sent to dwhitfield a copy of my php.ini file

Can you provide a screen capture of the error or an updated system profile we can check it's configurations?
