i/o stats for linux

[Era_Russland]

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

Thanks a lot

Hi,

I'm also interested in i/o stats, so I'll work on it tomorrow.
You're invited to help or contribute as much as possible

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.

Any hints are highly appreciated
