How to track cron runs about documentation HOT 9 CLOSED

How do track cron jobs so that I am alerted if they freeze (do not exit or have a really long run time)? Can that be done with DataDog?

from documentation.

You can use the dogwrap command that comes with the python client lib:

dogwrap -n myscript -k $API_KEY --submit_mode errors "/usr/local/bin/myscript.sh arg1 arg2"

This will call the command at the end of the script and send datadog events if it exits with a non-zero exit code. --submit_mode all will send events on every run.

(To get the python client lib you can install it with easy_install dogapi)

from documentation.

This is how we currently do it:

psql -c 'some maintenance query' 2>&1
    | tee -a /var/log/postgresql/maintenance.log
    | /usr/local/bin/dog event post --tags maintenance 'Doing some maintenance'

from documentation.

Is this up to date?

from documentation.

Yeah, that snippet would work. The pertinent part would be the "dog event post" part of the script. Needs some copy to explain the premise. Something like:

Often, you set cron jobs that trigger some meaningful script that you want to monitor and correlate with other metrics. For example, you might have a cron'd script to vacuum a Postgres table every day:

0 0 * * * psql -c 'vacuum verbose my_table' >> /var/log/postgres_vacuums.log 2>&1

Vacuum are particularly resource-intensive though, so you might want Datadog events for each time they run so you can correlate metrics and other events with vacuums. You can do this with the dog command line tool provided by the dogapi client library:

0 0 * * * psql -c 'vacuum verbose my_table' 2>&1 | tee -a /var/log/postgres_vacuums.log | /usr/local/bin/dog event post --tags maintenance 'Vacuuming my_table'

This will post an event tagged with #maintenance whose title is "Vacuuming my_table" and body has the log of the vacuum.

Another poke, is this still the official way to track cron runs?

from documentation.

This is exactly what I was looking for, thanks!

@clofresh sorry for digging this up. How can I install dogwrap these days ? Install dogapi didn't do it.

@c0ze I think dogapi is deprecated. Try pip install datadog instead. https://github.com/DataDog/datadogpy#installation
