Cron-Sentry: error reporting to Sentry of commands run via cron
Cron-Sentry is a python command-line wrapper that reports errors to Sentry (using raven) if the called script exits with a status other than zero.
Note: I've made updates to try to get this to behave in a more cron friendly way. Specifically, the old versions seemed to swallow all your errors if something was wrong with Sentry. The behaviour is now:
- try to run the command
- if it fails for any reason try to log that to sentry
- if logging to senty fails write the issues to the logger on stderr (along the the outputs of the failed command)
- this allows
MAIL_TOin cron to pick it up in the usual way
pip install cron-sentry
$ cron-sentry --help
usage: cron-sentry [-h] [--dsn SENTRY_DSN] [-M STRING_MAX_LENGTH] [--version] cmd [arg ...]
Wraps commands and reports those that fail to Sentry.
positional arguments:
cmd The command to run
optional arguments:
-h, --help show this help message and exit
--dsn SENTRY_DSN Sentry server address
-M STRING_MAX_LENGTH, --string-max-length STRING_MAX_LENGTH, --max-message-length STRING_MAX_LENGTH
The maximum characters of a string that should be sent
to Sentry (defaults to 4096)
--version show program's version number and exit
The Sentry server address can also be specified through the SENTRY_DSN
environment variable (and the --dsn option can be omitted).
crontab -e
MAIL_TO="failover_for_broken_sentry@example.com"
# SENTRY_DSN=https://<your_key>:<your_secret>@app.getsentry.com/<your_project_id>
# ^-- doesn't work for me, add dsn to /etc/cron-sentry.conf
