When you apply the configuration, can you click on the show errors and post that back to the forum?

Also, it looks like cron isn't running. Can you start the cron process by running the following?

Code: Select all

service crond start

There wasn't any error it was just stuck at applying config................................................................................

But I did figure it out. Done goofed and had /usr/local at 100% which locked us up.

We had the space increased from 1 gig on that file system to 6... and now it's filling up again at 72%

There a good way to manage that or minimize the space used by that file system???

Can you run this command and post the results so we can see which folder is filling up?

Code: Select all

du --max-depth=3 /usr/local

Looks like the perfdata folder has taken up the most space, run this and post the results.

Code: Select all

du --max-depth=1 /usr/local/nagios/share/perfdata
That folder is where all of the hosts and service's data is stored.

How many hosts and service's are you checking now?
Earlier in your post, you said that you were trying to import 1200 servers, are you still doing that many?

Yep, we're actually up to 1700 atm which is just Linux & Solaris host that we plan on running file system monitoring for. Really we're stress testing to an extent. But we'll need to use thousands of hosts as we plan on using Nagios XI for in store devices + File system monitoring for the enterprise.

The store devices you're looking at 30 CVT's per store and we have over 900 stores. Each CVT will be a host technically to boot. Is there a recommended threshold where to stop???

And yeah my screen maxed out:

Code: Select all

3020    /usr/local/nagios/share/perfdata/esu2v547
3020    /usr/local/nagios/share/perfdata/s66d0z10

5339840 /usr/local/nagios/share/perfdata
$
I deleted all but 2 of them since I'm sure my boss doesn't want me publishing thousands of server names on a community forum. If this is just performance data is there a setting we can tweak to minimize the data stored? I can talk with my bosses on what they want to see, we did increase the file system to 60 gigs so that should give us plenty of breathing room for now.

There isn't a way to shrink that folder with out changing the way the plugin's store their information but you could do some performance and database optimizations that will help a bit.
Here are a couple of links to documents that show you how to do that

Thanks, I'll take a look at these.

Also back to applying configurations. When we apply a config does it only apply what was changed or the entire config every time?

Just curious as we grow the server if we'll have increased wait times on applying the configurations. Right now we have about 2000 hosts and now adding services into the mix. Applying configs takes around 10 to 15 seconds.

Just curious.

Depends on your version. From our changelog:
- Changed the Apply Configuration process to only write out changed configuration files -SW, AB
This was implemented in 2014R1.1 primarily by our support manager, Andy Brist (abrist on the forums).

The apply configuration will only touch the files that were modified (after 2014R1.1).

You can easily test this - check the timestamps on the hosts/services:

Code: Select all

ll /usr/local/nagios/etc/hosts
ll /usr/local/nagios/etc/services
Modify one host/service in the CCM and apply configuration, then check the timestamps again. Only the config that was modified would have an "updated" timestamp.
All times are UTC-05:00
