Gronit

A Cron monitor written in Go.

Features:

• Update and check job status remotely
• View statistics of jobs
• Bare bones alternative to services like Cronitor

Installing:

$ go get github.com/zricethezav/gronit

Usage:

$ ./gronit

This will start a server on default port 3231. Change the port with -p or --port option.

Generate a job tracker (with a gronit server running):

$ curl 127.0.0.1:3231/create
{"id":"f7a324"}

/create generates a job tracking token. Now we can wrap any command with gronit.

# sample crontab
*/2 * * * * curl -s 127.0.0.1:3231/run/f7a324 && sleep `echo $((1 + RANDOM \% 5))` && curl -s 127.0.0.1:3231/complete/f7a324
