Highcharts work, mrtg graphs don't

Sure.

Here you go:

In the profile that you sent in, I found the following errors

Code: Select all

2015-04-29 08:57:14 [9021] [2] No Custom Template found for check_dummy_no_txns_seen (/usr/local/nagios/etc/pnp/check_commands/check_dummy_no_txns_seen.cfg)

2015-04-29 08:57:14 [9021] [2] No Custom Template found for check_xi_service_nsclient (/usr/local/nagios/etc/pnp/check_commands/check_xi_service_nsclient.cfg) 
2015-04-29 08:57:14 [9021] [2] Template is check_xi_service_nsclient.php

It looks like you had some custom PNP templates and now they are missing. Do you have a backup copy that you could replace them with?
You may also want to check this log file for any more missing templates.

Code: Select all

/usr/local/nagios/var/perfdata.log

Nether of those files exist on the old server.

Which file calls the template? I should be able to comment out the unused, right?

Thanks,

I found that those templates are created automatically so there isn't a config file that needs to edited to remove them.

Bad news is that the only way they are recreated is to delete the xml and rrd files associated with them which will delete all of the performance history for them.

So what you need to do is monitor this file for the "No Custom Template found"

Code: Select all

/usr/local/nagios/var/perfdata.log

Find the host that uses the service check with the missing template and under the following folder with the host name, the xml and rrd files need to be removed.

Code: Select all

/usr/local/nagios/share/perfdata

Once they are deleted, they will be recreated and your graphs should start to work for those service checks.

How does one look up a host by template?

[tgriep]

Login to the NagiosXI server in a shell.

Change to this directory.

Code: Select all

cd /usr/local/nagios/etc

Look for the missing template message in the perfdata.log file and do a search like this.

Code: Select all

grep -R check_dummy_no_txns_seen

This will bring up all of the files that have that template in it.
Open up those files, search for "check_dummy_no_txns_seen" and you should get the host_name and the service_description that you need.

That is just one example on how to do that.

Hi,

find ./ -type f | xargs grep check_dummy_no_txns_seen | wc -l
923

I'd hate to delete these then realize I actually needed them. So before I remove the RRD and XML files, can we say this is the cause of the old style MRTG graphs not showing up?


Thanks,

-J

[tgriep]

From what I read, those templates change how the data is stored in the rrd files so it could be the issue.
For a test, delete one of the bad files and see if it fixes the graphs.

[jwicks]

Hello,

I removed one of the RRD and XML files, and no change.

Any other things I might be able to try?

If there is any documentation on how the MRTG style graphs are created, please link it.

I have no idea how to troubleshoot this.

Thanks,

-Jason

Could you run the following and post back the results?

Code: Select all

rrdtool -V

Can you upload the new xml file that that was recreated after you deleted it so we can see the settings in it?
Could you upload the following files too?

Code: Select all

/usr/local/nagios/share/pnp/templates.dist/default.php
/usr/local/nagios/share/pnp/templates.dist/default.php.ORIG
