cmon (Cron Monitor?)
====
Come on.
I'm bored of installing God
or Bluepill.
I just want a simple command line interface for checking the state of something.
I want to define my expectations in RSpec
output_from("ruby script/delayed_job status")\
.should_not include("no instances running")
I want to be able to execute this simply on the command line
$ cd /path/to/my/project
$ cmon monitoring/delayed_job.cmon
I want to run this on cron, and have IT email me when things go wrong
# monitor this once an hour
# and email me if its down
MAILTO=my.email@example.com
0 * * * * cd /path/to/my/project && cmon monitoring/delayed_job.cmon
And maybe, if it goes wrong, I want it to restart it for me
0 * * * * cd /path/to/my/project && cmon monitoring/delayed_job.cmon || ruby script/delayed_job restart
C'mon

cmon (pronounced "come on") is a simple ruby library that uses rspec defining expectations
It says
- "if there's anything I can rely upon being up all the time, then its crontab"
- "let's use crontabs built in emailing to enable notifications"
- "let's return posix exit codes, so we can use bash's logical operators to chain commands, and responses together
