Hey Chaman, 200 devices does not say much, what kind of devices? more importantly, how many interfaces and sensors will these 200 devices have that Observium will need to poll?
What kind of storage do you use? I'm pretty sure just a SSD-disk with no rrdcached is the best option here.

Just want to confirm what Markus telling.
We are running 600 devices, 25k interfaces and 20k sensors on a couple of SSDs without rrdcache.

Hi,
'-s www-data' - here must be user under which the poller runs. Also you must set in config.php: $config['rrdcached'] = "unix:/var/run/rrdcached.sock";
All other options seems as fine if correct permissions in /mnt/ramdisk/

Question for Peter,
Curious if you’ve separated your mysql database to another host, or if your SSD’s provide plenty of IO for that many devices plus the DB?
Almost 700 devices here, with 40k interfaces and SAS raid 10 is starting not to cut it. :/
Thanks,

Chaman, You need to move the SQL Database off the same disk as the rrds (separate the disk I/O for the DB and rrd)
for me, as i use VMware, i have two vmdks as lvm for the DB and two vmdks as lvm for the rrds.
if you don't use vmWare or any kind of external disk system, for example fibre connected disk array, then you will have to have a separate host for the SQL DB.
My host is quite busy but busy, but doesn't miss a beat.

I don't think rrdcached with a ramdisk makes any sense at all? Or is /mnt/ramdisk not a ramdisk?
