/var/lib/mrtg/10.64.0.2_562.rrd does not exist.

Good morning guys,

We are running into an issue with newly created services. We used the configuration wizard to monitor a network switch and checked the boxes next to the port we choose to monitor. After completion several of the services are getting an error close to the one below. I have confirmed that the file is in fact missing.

/var/lib/mrtg/10.64.0.2_562.rrd does not exist.

Can you post a screenshot showing us where you are seeing that error?

Here is where we are seeing it.

Thanks for that. To clarify, which wizard did you use to set these hosts / services up? Also, what version is it? (Admin -> Manage Config Wizards)

[dshearon]

We are using the wizard listed below.

Network Switch / Router
Monitor a network switch or router.
Version: 2.1.9

How often are these checks running? I tried to replicate this, but I was unable to. It seems the data is not being created though. It should only show this error if the check has ran once, or the RRD data is not creating properly.

Also, what are the results of these two commands?

Code: Select all

ls -l /var/lib
ls -l /var/lib/mrtg/

We are running checks once every 5 minutes unless there is an issue and then once every minute.

Can you log as root to the XI server, run the following commands and post the output?

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok

This should should show us any errors creating / generating the .rrd files needed for the bandwidth check.

Then run the following and post it too.

Code: Select all

ps -ef
ls -l /etc/mrtg/conf.d

I want to see of the config files were created for mrtg.

Here you go. I could not screen capture the entire output from the second command, let me know if you need another section.

Can you run the following and post the output here?

Code: Select all

time LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
ls -l /var/lock/mrtg/

In the capture you did provide, someone on February 16th is deleting some rrd files, do you know why?
