Sensu shell helper

Sensu Classic (EOL)
4

Hmm. I don’t know if parsing the output of these commands is inside the scope of the sensu-helper-script.

But, if the command you have in mind (or a filter script to mutate it) can output appropriately, you might be able to do something like this?

sensu-shell-helper -j ‘“metric”: true’ -H ‘[“graphite”]’ “/etc/sensu/plugins/vmstat-metrics.rb --scheme stats.:::name:::”

Produces:

{

“name”: “etc_sensu_plugins_vmstat-metrics.rb–scheme_stats.name”,

“output”: “bla”,

“metric”: true

“handlers”: [“graphite”],

“status”: 0

}

I don’t know. Probably will work? Use -d to debug the json output sensu-shell-helper is making until it works?

Pull requests welcome if you can modify it to handle metrics better, but I wouldn’t want to make assumptions about how peoples handlers are setup and stuff.

Agreed - this is really useful, Kyle.

I'd like to augment your script, if possible, with metrics.



For example, the target could optionally be run via time (/usr/bin/time on Ubuntu) and it could return metrics for:

  • Length of real time the job took to run

  • Kernel-mode time

  • User-mode time

  • Maximum resident set size (memory) used

  • Number of swaps caused

  • Etc…

    This would certainly be very useful for my use-cases. What do you think?

    Kind regards,

    Mike

          I wrote this shell script to make it easier for me to add sensu checks for my cron jobs with minimal overhead:

            I hope it might be useful to others too. Feel free to open issues / pull requests if it doesn't work for you. (it is not production tested)

Example cron usage:

            0 * * * * /usr/bin/sensu-shell-helper /usr/bin/apt-get update

            No more cron spam, alerts when it fails, and clears when it resolves.
