This is accomplished via the dogwrap command line tool provided by the dogapi client library:
For an example of dogwrap in action, let's use cron. 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 is 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.
dogwrap -n "Vacuuming mytable" -k $API_KEY --submit_mode errors "psql -c 'vacuum verbose my_table' 2>&1 /var/log/postgres_vacuums.log
This will call the command at the end of the script and send Datadog events if it exits with a non-zero exit code (i.e. an error).
--submit_mode all will send events on every run.
(To get the python client lib you can install it with
Another option to consider is cronner, a command line utility that wraps periodic (cron) jobs for statistics gathering and success monitoring written by PagerDuty:
