DSS Server stats (check_sys)
Referring to my previous post regarding server stats (check_sys);
After hitting "remove" several (5+) times, it works and is also fast.
I had a high load (for whatever reason as nothing was active on the DSS), but since my RAID-5 is still migrating from 64k to 256k (nearly 48h now, sigh!) there might be some explanations..
Now regarding check_sys, which I see the first time after the hint from To-M:
- it seems open to anyone without auth ? No big issue for me but maybe noticable
- I'm missing some valuable things: IOWait CPU, Block/Disk-IO
For anybody interested, I'm monitoring most already with MRTG remotely, my config below.
Some notes on this:
- Ethernet stats are limited (read: useless) to smthg. above 100MBit/s due to 32bit counter overflow. The DSS doesn't provide ifHCInOctets/ifHCOutOctets (64bit counters) to workaround.. I'm also monitoring the Switch to get the traffic..
- I haven't worked out the DiskIO-counters yet, which would be very interesting. Somehow I'd need some hints which devices are what as my counters for sdaX don't show the same as block-io (which they should in testbed). Any explanantion appreciated..
- What is *really* missing from the snmp in DSS is hrStorageTable which could be used to monitor volume-usage (commented out below)
Just replace SNMPCOMMUNITY and dss-hostname to use.
(config in next post due to 10k char size limit)
