Hello,
I want to setup I/O statistic for our corporate linux servers.
I have already traffic/cpu load statistic from this servers but i/o stat is very important for me also.
I found some templates for this kind of stats but don't have luck to use it.
I step though install manual but still don't have graphs.
I tried Upgraded: snmpdiskio 0.9.4 (Disk I/O statistics on Linux) template.
Is this template up2date?
ERROR: opening '/var/www/html/cacti/rra/server_15min_loadavg_122.rrd': No such file or directory
Could someone help me to setup cacti with I/O stats. This is very important task for me
Failure to create a rrd file may be a result of
- failing host access (if other parameters are graphing fine, this is surely not matching)
- failing OID access
The last one is more likely. IMHO, for SNMP access to disk I/O stats, a specific SNMP module is required. I'm quite sure, that this should be mentioned in the thread you found the templates in.
Then, you may try to snmpwalk against those DISK I/O OIDs manually to verify correct installation of these SNMP modules on the target systems

@Reinhard: do you eventually know about some Debian specific instructions on installing those MIBs?
For now I've found out, that there must be a way to request the i/o stats manually AND that it would be possible to gather its data via a perl script.
Of course, before I'll start on coding this script, I'd like to use an existing way.

1) These are no MIBs, it's some SNMP module compiled into SNMP itself. Please search the net-snmp-users list. It comes up from time to time
2) If you compile net-snmp yourself, you will need to include the ucd-snmp/diskio MIB module at compilation time thus:
