Log parse script

pavan27 · 02-08-2016, 01:13 PM

Hello Experts,
i am trying to write script to monitor replication, fir this i need to read the replication log file and report if my condition is matched. i have below file

Code:

stream id: 8ad5917c1992e82b0c5a9577124603ab/beer-sample/beer-sample
   status: running
   source: beer-sample
   target: /remoteClusters/8ad5917c1992e82b0c5a9577124603ab/buckets/beer-sample
stream id: 8ad5917c1992e82b0c5a9577124603ab/beer-sample/beer-sample1
   status: aborted  >>>>>>>>
   source: beer-sample
   target: /remoteClusters/8ad5917c1992e82b0c5a9577124603ab/buckets/beer-sample1

from the above file, i have two replication streams, one stream is going good another stream is aborted.
my requirement is to read stream id and its status (below line) and report only failed portion (3 lines below stream id (status, source, target).
could you please help me to solve this puzzle.

Thank you,

You've asked similar questions in the past. And since you say you're trying to write a script, why don't you POST that script?? We are not going to write it for you, but will be happy to help.

Does the script do what you wished it to do? If so, then it's good that you posted it and then also please mark the thread as solved. If there are problems, then it might be helpful to describe those problems.

I realise you have only shown a snippet of your script, but am curious how the first line shown would execute correctly if the definition is coming after it is called? Unless of course you have
multiple definitions of the same function?? (if so this could cause a headache in the future)
