**Cronfed** monitors basic batch jobs, or any other cron-based
scheduled commands by parsing a given mailbox and turning it into an
RSS feed. The feed can in turn be monitored with your browser_,
feedreader_ or other RSS-compatible service (such as IFTTT_).
Simply add a cron job to generate the feed, pointing it at a
web-accessible location (such as a ``public_html`` directory or your
site's assets directory). Check out the example for some real-world
Cronfed usage, with an explanation of how cron and Cronfed work
together.
Cronfed is **Minimum Viable Monitoring**, aimed at providing a basic
threshold of monitoring without complex automation or dependencies.
It's targeted at smaller projects which otherwise might go without any
monitoring at all. It's so easy to set up and use on the standard
Linux/BSD machine that there's no reason to not use it from
Day 1. While Cronfed makes attempts at limiting the amount of
information externalized, it is not recommended for jobs with
extremely-sensitive information.
*"Cronfed: It's the least you could do!"*
Installation
------------
Cronfed is pure Python, has no system library dependencies, and should
work wonders on any POSIX machine with a functioning cron daemon and
local mail system::
pip install cronfed
Run ``python -m cronfed --help`` to see options, or read on for a
usage example.
Example
-------
First, let's look at a basic cron job. This one will fetch our data
once an hour, on the hour::
0 * * * * /usr/bin/python /home/myuser/project/fetch.py 2>&1 | tee -a /home/myuser/project/logs/fetch.txt
Notice how the output (``stdout`` + ``stderr``) is piped to a log file,
but using the ``tee`` command. This ensures that the output goes to the
file as well as ``stdout``. ``cron`` captures that ``stdout`` and puts it
into an email, which then gets sent to the user who owns the job. This
usually means the email goes to ``myuser@localhost``, which on many
distributions means that it is saved to ``/var/mail/myuser``. Do note
that if the command generates no output, then ``cron`` **will not send
an email**, so it's a good idea to emit an error message.
Once we're sure that email is being delivered, we're halfway
there. Now we just need the actual Cronfed cronjob::
*/15 * * * * /usr/bin/python -m cronfed --output /var/www/mysite/assets/cronfed.rss /var/mail/myuser 2>&1 | tee -a /home/myuser/project/logs/cronfed.txt
In this example we have the installed ``cronfed`` module regenerating
our feed every fifteen minutes. This is a pretty quick process in most
cases, so feel free to make it more often. In this case, the output of
cronfed itself is monitored in exactly the same way as normal cron
jobs, with a logfile and email to ``user@localhost``.
History
-------
Cronfed was created for `Hatnote`_ to monitor the periodic data
refreshes necessary to generate `The Weeklypedia`_. See those cron
jobs and more in the `Weeklypedia crontab`_.
