Consul Alerts

[Dexter John Genterone]

Hi All, 

We've been working on a monitoring system based on consul checks and we've decided to open source it. :) It's using consul watches and the configuration is stored on the KV. Notifications are sent when a check has changed status and has stayed at it for a certain duration (prevents flapping). At the moment we got a few built-in notifiers (email, logger, influxdb and slack) but it's quite easy to add custom ones via configuration. 

Check it out here: https://github.com/AcalephStorage/consul-alerts

Still needs some improvements, better doc, cleanup, and need to add a few built-in notifier but at the moment it does what we need (send health check status via email and influxdb). Posting this here in case someone might find it useful and any contributions would be awesome. :) 

Cheers,

~Dexter

Ohh, I like this, I like this a lot!

 

Not sure yet where it fits; I think its a couple of steps ahead of us on the consul journey, but I have a feeling we're going to want something like this at some point. Great work :)

Cheers,

Hi All,

Just a follow up for consul-alerts, we now have binary releases, a Docker image and a few updates including Slack and Influxdb support.

We'd love feedback (and contributions) so please try it out and lets us know what you think!

Cheers,

This is very interesting! Well done :)

Any chance you could provide a K/V config example for a custom alert? I would like to test this to execute a script we already have for release tracking.

Cheers,

Thanks. 

You can add your own custom health check notifier by setting consul's KV:

KEY: consul-alerts/config/notifiers/custom

VALUE: [ "/path/to/custom/script", "/path/to/another/script" ]

Value should be a JSON array pointing to scripts that will handle the notification. The data passed is a list of checks that have changed status. It can be read via STDIN.

If you need the custom events handlers, you can add them by setting consul's KV:

KEY: consul-alerts/config/events/handlers

VALUE: [ "/path/to/custom/script", "/path/to/another/script" ]

This passes the event payload to the list of scripts defined every time you call consul's event command. (`consul event -name payload`)

Hope this answers the question. We're still working on adding a feature where we can load the config via CLI. By then I'll add a sample config file. 

Cheers,

~Dexter

Hello,

can I use the slack notifier for example for events or it works only for checks?

Hey Marian,

I’m not sure about the open source tool, but our commercial Atlas offering can do this:
