Nagios Support Forum

Hi Guys,

I have upgraded my Nagios Core 3.5 to Version 4.0.2. Everything seems normal, But my pnp graphs were stopped working after upgrade og my Nagios Core to 4.0.2.

Any suggestions or fixes please?

Thanks,
KalyanP

Just a stab at the dark but perhaps you need to switch to Bulk Mode with NPCD.

Hi Box293,

Thanks for your quick reply.
Currently I am using pnp-0.4 version. So what can I do now?

Thanks,

I have followed below URL to upgrade pnp:

From URL: https://docs.pnp4nagios.org/pnp-0.6/upgrade I didn't understand the section "Attention" like in which file we need to update that '$lower'' and "Upgrade scenario using NPCD"

Please suggest me any solution.

Thanks,

Can you post the defined commands for perfdata processing?

Hi Abrist,

I have already posted them:

commands
-------------------

define host {
name host-pnp
register 0
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
}

define service {
name srv-pnp
register 0
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
}

Thanks,
KalyanP

sorry,

define command {
command_name process-host-perfdata
command_line /usr/bin/perl /usr/local/nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
}

define command {
command_name process-service-perfdata
command_line /usr/bin/perl /usr/local/nagios/libexec/process_perfdata.pl
}

To start using the NPCD mode the commands are different:

For example, on my test system:
You also need to configure NPCD and start it, on my test system I did this with: NOTE: this steps were from a v4 test system so on v6 it might be a little different.

Thank you box293 for your support. It worked for me.

Thanks,
