Cron Job Monitoring with Tornado

In NetEye environments we use Tornado to collect events, elaborate on them, and send notifications based on them from a lot of sources (syslog, email, SNMP traps and so on). In this article I’d like to suggest a different use case: how to use Tornado to monitor your cron jobs. In our example we want to use NetEye to track the status of a sequence of dependent scripts.

Suppose you need to weekly run a script composed of three commands: the first two extract data from different sources, while the third one merges the previously extracted data. For each script we want to keep track of the results in NetEye. We also want to be notified when any script is not executed.

Here the three scripts :

extract-info-source1
extract-info-source2
merge-sources

Host and Service Creation

We begin by creating a dummy host:

then creating (if it’s not already present) a service template with a check interval:

and next a service template with an auto-reset delay of one week:

Finally, create the three services (here’s the first one):

Deploy the configuration in Director and we’ll now have our host/services ready to be used:

That’s it for today. In my next article we’ll create the Tornado configuration to send the script status on NetEye and monitor your scheduled jobs.

These Solutions are Engineered by Humans

Did you find this article interesting? Are you an “under the hood” kind of person? We’re really big on automation and we’re always looking for people in a similar vein to fill roles like this one as well as other roles here at Würth Phoenix.
