[Orca-dev] Help needed with orcallator.cfg modification

[hudesd at hra.nyc.gov]

How do I modify orcallator.cfg so that zfs information is collected and processed?
There's three groups of information: zpool, zfs and kstat.  For zpool the interest is to collect overall information as given in "zpool status" and "zpool iostat".
For each zfs filesystem it is sometimes interesting/usefl to collect the property information esp. usage and compressratio (and the mount point and name to go with it).

For the zfs subsystem as a whole, the kstat information.
The arcstats are particularly useful when one modifies the size of the ARC.


Here's sample data for each of these:

# zpool iostat
               capacity     operations    bandwidth
pool         used  avail   read  write   read  write
----------  -----  -----  -----  -----  -----  -----
rpool       8.88G  24.9G      0      1  1.64K  9.37K
# zpool status
  pool: rpool
 state: ONLINE
 scrub: none requested
config:

        NAME          STATE     READ WRITE CKSUM
        rpool         ONLINE       0     0     0
          mirror      ONLINE       0     0     0
            c1t0d0s0  ONLINE       0     0     0
            c1t1d0s0  ONLINE       0     0     0
