Readme
Use this val to monitor your schedule jobs for any issues and report them directly to Sentry Crons.
- After forking, find the DSN for your Sentry project by going to Settings > Projects > Select your project >Settings > Client Keys (DSN).
- Add your DSN to as a
SENTRY_DSNin your val.town environment variables. - Change the
monitorConfig.schedule.valueCrontab expression to match your job run. - Replace the
run()function with your scheduled function. - Alter any other monitor config properties to better fit your scheduled function. Learn more.
This val will automatically create and set up a Cron monitor in Sentry, and report all of your runs as check-ins. If your job ever misses a run or fails, Sentry will notify you.
Any errors that occur in your scheduled function will be reported directly into Sentry:
