Hi,
Fusion had been working great, but now it's not reporting any data from our XI servers.
We are now getting "No servers have checked in with data yet. " from all our XI servers and we have no idea why.
It was working fine. It's a fairly new build (a couple of months).
Also, the "/var/lib/mysql/ibdata1" file has grown very large very quickly (16GB!) and filled up the disk. I had to grow the vmdk and add more filesystem.
any help would be awesome!!!
Thanks

Hello, @PlumpyChunq . The fact that your DB has significantly grown in size tells me that you may be monitoring a lot of services/hosts. Fusion works by pulling all kinds of data from all existing hosts and services, and then processing it for the user. So if you're monitoring hundreds of servers 16GB may be a normal size for the Database. If the database consumption is a big concern, you may enableIgnore XI host/service meta data option. That option can be enabled in Fusion Web Interface. Click on servers menu, and then on settings next to each individual fused server. You'll see this menu: As far as your first problem goes, please refer to this tutorial on optimizing Fusion:

You may also increase the number of simultaneous pollers from 1 to 2 or 3.

Could it be that Fusion stopped polling data after the memory got maxed out? Also, after you increase the VM memory size, you may want to restart fusion with:

Thanks for your response.
This did not work. I'm not really concerned about the size of the file. I just got big fast and I didn't know if that was normal.
I had already changed the number of pollers to match the number of XI servers (14) but that didn't seem to make a difference. I have sense reduced it down to 5. I had already increased the memory to 8GB even though it looks like it's not memory bound at all.
Any other ideas?
Thanks

@PlumpyChunq , We'd need to take a look at the log files. Can you upload:
/usr/local/nagiosfusion/var/poller.log and /var/log/httpd/error_log
Also, can you go to the Fused servers menu then clcik on edit settings. In that menu please run Test Fusion Settings. Do you see 2 green check marks, or are any of them red?
And finally, in Admin menu, click on System Status dashboard in the left column. Are all system statuses green on that dashboard?

I ended up rebuilding the Fusion server with a bigger disk and it's working for now.
Thanks for you help.
Please close case.

Thanks for reporting back what you did to resolve the issue. I go ahead and lock the post for you.
