Disk i/o monitoring
Sorry if this is wrong place to post, but I'm not sure what would be better.
I'm using pfSense with squid's cache on a second drive, da1, and I'd like to monitor the disk i/o, but iostat doesn't exist and I'm afraid to install packages because I think it might break something else. I've looked at using SNMP, but when I walk the mib, I don't see anything about disk i/o.
checkout the binary systat
systat -vm <time in="" seconds="">systat -vm 5
systat -io 5
This will be sufficient for present purposes.
If anyone knows how to get SNMP working for disk I/O, it would be appreciated.
