pnp4nagios 0.6.25 BULK Mode with NPCD

Hello everyone,
I've decided to come back and try adding pnp4nagios back into my nagios core

When I run perl verify_pnp_config --mode bulk+npcd --config=/usr/local/nagios/etc/nagios.cfg --pnpcfg=/usr/local/pnp4nagios/etc/

Try editing the file /usr/local/nagios/etc/pnp/npcd.cfg and change the defined group in there.

Once done, restart the npcd service:

Code: Select all

service npcd restart
Does this help?

Thank you!

I have already modified /usr/local/pnp4nagios/etc/npcd.cfg
I hope that's the right file for me as the one you specified doesn't exist on my system

user = nagios
group = nagcmd

When I browse to server-ip/pnp4nagios i am actually getting graphs generated, however under services I'm seeing Host Perfdata and PING, so not all services that I have show up, Windows hosts where I'm using wmic checks all show up:
Host Perfdata CPU DFS Replication Disk Space - All Event Log Application War... Event Log System Warnings Network Page File RAM Utilisation

For example I have a Cisco switch - NDC-SW-Admin with 54 checks but in pnp4nagios I'm only seeing the ping service and Host Perfdata, so 2 out of 54. How does pnp4nagios know which services to graph and which not to?
EDIT: Looks like the other's can't really be graphed as they are text info only

Yeah thats OK, different systems have different directories.

Bang that's exactly it.

I did a talk on this at the Nagios World Conference, you can watch it here:

https://www.youtube.com/watch?v=kqA2KcpUFg4
http://www.slideshare.net/nagiosinc/tro ... and-graphs

While it's Nagios XI based, the basics about performance data and plugins is the same and the directories might be a bit different in your installation.

I do have one question, I saw the youtube links late last night and didn't have time to watch them, saw about 25 min of the first one.

Trying to make sense out why mrtg and pnp4nagios are not really showing the same data. From the video if I remember correctly pnp4nagios averages data but still these don't look right to me.

I am looking at the data source in and in mrtg we can see it's more or less a steady 12 MB/s from 7-11 this morning, that same data in pnp4nagios (Datasource: in) doesn't show much at all - from 7-11 it's almost zero

Bare with me as I don't often use these two products outside of Nagios XI.

So I assume you have MRTG working and then you have a Nagios service setup which queries the MRTG data (for which PNP graphs are generated)`?

Can you show us the MRTG config for Tunnel0 and then the Nagios service definition for Tunnel 0.

Yeah I have mrtg installed and it's monitoring the switch ports. Sorry I only use the free version of Nagios Core

This is the part of mrtg.cfg that shows tunnel0, just edited this part again, didn't paste properly

I noticed in the previously attached screenshot when you look at the pnp4nagios side it shows the warning and critical which are in bytes but not translated correctly ?? - Warning shows 11250000.000000 while for example KB/s Max shows 84.5176
Looks like way too many zeroes in the Warning Critical part?

Don't be sorry, Nagios is great because there are so many ways of using it!

So basically what is happening here is that MRTG has the data most closest to the device.

When I checks it gets an octets value and then calculates the difference from last time and stores this in /var/www/mrtg/192.168.199.1_5.log.

Then your nagios service queries this file and calculates the difference from last time and then the plugin returns this as performance data.

PNP then gets the performance data and when it inserts it into it's RRD file it calculates the difference from last time and hence the data is averaged some more.

This might not be 100% correct but it's close. The point I'm making is that your PNP graphs are the furtherest from the source so the averaging is reducing the results.

But also, what is the command definition for check_local_mrtgtraf ? And what is the specific plugin that is being used, where did you download it from. I'm guessing that the last argument "10" is for an option which would have something to do with the interface speed perhaps?
