probe logmon

[Jose Romero]

Dear community, I am trying to use the logmon probe so that when I run a command it reads the output of the command example:

$ crsctl status res -t | grep -A 1 LISTENER_SCAN2
ora.LISTENER_SCAN2.lsnr
      1        ONLINE  ONLINE       ithssdfdfvervgrg05          STABLE

where

ONLINE is the correct status, but otherwise generate an alarm.

could you guide me

Try ticking the "match on every run" box, that inverts logmon to alert when it doesn't find a match.

Set the mode to command then you just treat the output as if it were a file.

Then set up your watchers to match everything that should be in the file with the option "abort on match" set.

Then set up a final watcher that matches everything /.*/ for your "otherwise' alarm.

So you'd have 3 watchers based on the output you provided - the order displayed is important since they are evaluated sequentially from top to bottom

One that matches /.*?ora.LISTENER_SCAN2.lsnr.*/ and doesn't result in an error and has abort on match set

One that matches /.*?ONLINE.*/ and clears the error and has abort on match set

One that matches /.*/ and sets the error

As an alternative you can change your command to

crsctl status res -t | grep -A 1 LISTENER_SCAN2 | grep "ONLINE" | wc -l

the wc (word count, -l = lines) will report the number of ONLINE lines selected - so you'll get a 0 if none which is your error case and 1 (or more) for the OK case
