It might help if you included a couple of references/examples
of the pages that are slow.
To give you something to compare against, we’re running
Observium on an ESX VM – 4x Xeon X5690 @ 3.5GHz, 8GB RAM, no
idea on storage – but we’re at a pretty consistent 40-50%
utilization at all times, using about 2GB of RAM. This is with
~200 devices and 16K ports.
I looked at a Cisco switch stack that has 115 active ports.
Graphs > System loaded in .45 seconds, which is only 16
different graphs between four categories. Likewise, the Ports
page loaded at .64 seconds with the miniature preview graphs.
Clicking on a specific port, it loaded 24 graphs in .49
seconds.
Now…I have some custom port lists, one of which is 36 graphs,
which loaded in .53 seconds. However, I have another group that
has…a metric shit-tonne of ports and graphs on it – hundreds of
them. The page loaded in 1.07 seconds, but it took several
seconds more for all of the individual graphs to populate, which
I expect considering the sheer number of them present in that
page. I don’t know if that’s simply the browser catching up, or
if it’s still generating the actual graphs in the background.
Hi,
I am currently using Observium on 149 switches with a
total of 10173 ports.
I can't say that anything is wrong with it, but the web
interface seems a bit slow especially when you want to
display pages with a lot of graphs.
Observium is currently running in a VM with 4 xeon E5-2650
cores and 3Gb of ram.
It's virtual disks are on a local raid5 composed of 10K
SAS disks.
Observium report that it's VM use on average 25% of its
CPUs with spikes at 40% when the web interface is heavily
used.
The disk I/O doesn't go past 150 ops OUT and rare spikes
at 50 IN.
Anyone could advise on what kind of hardware or software
tweaking could help speed up the thing ?
Are they special requirements/tunnings for the rrd storage
or the mysql database ?
Best regards,
Louis
