But why though? :D

The poller-wrapper's entire purpose is to do what you're doing here :D

Yeah, I usually even out the server load by splitting the number of
devices in 5 and start the polling of them 1 minute apart with cron
like this:
0-59/5 *     * * *   observium    /opt/observium/observium-wrapper
polling -i 5 -n 0 >> /dev/null 2>&1
1-59/5 *     * * *   observium    /opt/observium/observium-wrapper
polling -i 5 -n 1 >> /dev/null 2>&1
2-59/5 *     * * *   observium    /opt/observium/observium-wrapper
polling -i 5 -n 2 >> /dev/null 2>&1
3-59/5 *     * * *   observium    /opt/observium/observium-wrapper
polling -i 5 -n 3 >> /dev/null 2>&1
4-59/5 *     * * *   observium    /opt/observium/observium-wrapper
polling -i 5 -n 4 >> /dev/null 2>&1

This makes it work with a lot fewer threads and the load on disk and
database is much lower as only 1/5 of the data needs to be progressed
at the same time.

You should probably decide threads to even out the load. The goal is
to be as close to 300 seconds as you can manage, else you'll get
spiky io and myself load.

Wow!  What hardware are you using? Where are your devices located?
I’m running about 90s for around 900 devices (21,000+ ports),
but I have to transverse WAN links for 95% of it.

Hi guys,

just wanted to show the new Observium I deployed for a customer
this week :)

​

Everything polled from one single server without problems
(pollingtime is about 140s for all devices)

Big thanks to Mike who helped me identify and fix a scaling issue
when running a huge amount of threads. (if you run an
Observium-install that runs poller-wrapper with 100+ threads you
should check out r9333)
