Monitor anything (with JBison)

We have recently released a new version of JBison (, our software-as-a-service web&application monitoring website.

The highlight of this release are the so-called “JSON monitors”. What can you monitor with them? Basically – anything. JSON monitors allow to monitor an arbitrary metric of your application in three easy steps, with minimal setup.

How is that possible? First you need to expose, as a flat JSON map, the custom metrics that you would like to be monitored. There are no constraints as to the keys or values; you can have entries for free memory, task queue size, status of a link to a third party service, etc. The JSON can be publicly available, or firewalled but you will have to let JBison in (see the FAQ). At the same time you can use HTTP authentication to secure access to the JSON. Example:

GET { "mail_queue_size": 91, "shipping_queue_size": 182, "since_last_import_seconds": 1086, "system_status": "ok", "free_memory_mb": 1024 }

Next, you need to login to JBison, and go to the “Add a new monitor” page. There you have to point JBison to the JSON, and define the constraints:

And that’s it! When the monitor is saved, the given constraints will be checked every 5 minutes. If any constraint is broken, you will be immediately notified by e-mail. That way, any custom metric can be easily monitored. Moreover all numeric metrics will be graphed, giving you an overview of how the values change during the last day.

Apart from the new JSON monitors, JBison also offers other types of monitors, such as “Ping” for monitoring a webpage (either just the response time or if it contains specified content).

Developing quite a lot of software ourselves, we often needed the custom metric monitoring functionality, but didn’t manage to find an online service which would offer such features. The JSON monitors in JBison have already proven very useful in our projects, and we hope that you will find them useful as well.

During the beta period, the service is free, so don’t hesitate and create an account – it’s really simple. And as always, as we are further developing JBison, any feedback will be highly appreciated!
