I agree,also when choosing SSD make sure to pick a enterprise SSD as the RRD-writes easily can wear out a consumer-grade SSD with that much polling going on./Markus2017-12-04 15:09 GMT+01:00 Moerman, Maarten <mmoerman@ebay.com>:Hi, I monitor currently 800+ devices on a single box, and doing it on 16 cores @ 3.5ghz,64GB ram and the RRD directory mounted on a raid SSD disk
With this setup, I can probably even get away with 1min polling.
Main points:
- Lots of cores, I would suggest double what I have to start with, lots’ of cores AND high speed of the cores is important
- SSD for RRD storage (straight mount, no symlink) (currently around 120gb in use)
- DO spend the time on tuning snmp parameters (figuring out which devices are slow, and needs max-rep optimizations)
- No-atime mounting of the file system
- Play-around with thread settings of the poller.
If you have the hardware to spread it out over multiple boxes, go for it, you’ll get better performance for sure.

Subject: [Observium] Observium Hardware requirements
Hi Friends,
My company has a PRO Subscription and we plan to implement Observium horizontally:
- Dedicated MySQL DB
- Dedicated RRD and web interface
- Main Poller
- Maybe Poller #2
We need your advice about hardware requirements to poll ~2500 devices and ~100.000 ports.
Thanks,
Juan Camilo Villamil B.
