Re: [p4] Monitor P4D with Datadog

Posted on behalf of forum user 'P4Reg'.

Just adding a couple of extra comments here about parsing output (it won't
add anything extra to what Matt said, but can make for shorter code)

The -F formatting option that p4 has can streamline a command and often removes
the need to parse the standard output of p4 commands using sed/awk etc.

..So
uptime=`/p4/common/bin/p4master_run 1 /p4/1/bin/p4_1 info | /bin/grep
'uptime' | /bin/awk '{print $3}'

..shortens to:
uptime=`p4 -ztag -F %serverUptime% info`

..and
version=`/p4/common/bin/p4master_run 1 /p4/1/bin/p4_1 info | /bin/grep
'version' | /bin/awk '{print $3}'`

..shortens to 

p4 -ztag -F %serverVersion% info

You can read more about the -F option in    
https://www.perforce.com/blog/130826/fun-formatting  and in this Knowledge Base
article  Formatting p4 command output using the -F global option with examples
[http://answers.perforce.com/articles/KB/15148/?q=Formatting+p4+command+output+using+the+-F+global+option+with+examples&l=en_US&fs=Search&pn=1]

Equally useful for simplified on the fly replacement of fields in forms is the
--field client side option (rather than the more traditional " p4 user -o |
sed "s/some item on the form/to something else/" | p4 user -i  ) :
