Announcing OneBusAway Watchdog

[Sean Barbeau]

Hi OBA Developers,
I'd like to announce a new tool for OBA server admins - "OneBusAway Watchdog" (https://github.com/OneBusAway/onebusaway-watchdog).

OBA Watchdog is a Python script that periodically queries a OBA REST API and checks the results to make sure that everything is working correctly (e.g., API responds properly, real-time data exists in the output, no unrealistic results like 100% ontime performance).  If something is wrong, it fires off an email to the server admin.  More details are available in the readme in the Github repo above.

This was created by Derek Edwards and Landon Reed at Georgia Tech, but since they're both tied up in other projects I'm the one that gets to share the good news :).

The tool is still in an early state, but its a great foundation to build upon.

Sean, this is good stuff.  I would also encourage you to think about integrating this with something like Amazon Cloudwatch (which you can use even if your servers are not hosted on Amazon).  You can:

* submit any custom numerical metric into AWS (e.g. 0-or-1 for whether something works at all, %on time performance, response times, etc)

* in AWS (i.e. through configuration, not through code) set parameters for when an alarm is fired (e.g. if a given metric is at zero for more than 5 minutes)

* elsewhere in AWS, control what happens when a given alarm does fire (e.g. who gets the email or SMS, etc)

 

We have made extensive use of this for our project and it has been wonderful.  For fewer than 10 metrics, you can use this for free as part of Amazon’s free tier: http://aws.amazon.com/free/

 

Thanks,

Mike

Excellent. Thanks for the heads up. I'll look into that this weekend.

Oh yeah, also, with AWS you can see any metric going back up to 2 weeks.  This also is very very helpful for real-time problem solving as well as post-mortem analysis.

 

Thanks

Mike,
Thanks for the feedback - I filed this as an enhancement issue on the OBA Watchdog project so it doesn't get lost in the shuffle:

FWIW - Puget Sound is also looking at CloudWatch for display purposes
