I’ve got sensu enabled now, finally taken nagios out to pasture and shot it. You may now clap.

Thanks! Ok, anyway, when you get your new toy you want to start leveraging some of the cool things it can do. My company uses campfire as our main daily communication, and luckily there’s a campfire handler for sensu! Naturally we should leverage it right? Well, it seems with 0.12 sensu, it’s not exactly a cup o’ tea.

Go ahead and add you campfire handler and you’ll notice quickly:

Note: I’d like to thank Bethany Erskine for all the advice and the gist I just stole to explain this.

Ok, honestly it’ll be locked up in the sensu-client.log but if you break up the json it’ll look like the above. Anyway….

So as you can see it fails with the SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (Faraday::Error::ConnectionFailed) trying to verify the certs, I spent some time trying to updated the pkg version of the ssl certs, reading more than I ever wanted to know about SSL, finally I pinged Bethany asked her after finding that gist.

She responded back with something that just seemed so obious, if you look at the handler it defaults to true.

Change that to it to something like:

Tinder::Campfire.new('mydomain', :ssl_verify => false, :token => '7505e9c7ed5c30a77dTHIS_IS_FAKE93029a494eb7c3d20')

And…all the sudden you’ve got messages in your campfire channel.

Yes, yes, you should verify ssl, but honestly, for what you get out of sensu for this, it’s gravey for now. Plus I think after I ping Sean Porter about this issue in a passive/aggressive manner he’ll probably get it fixed. Love ya Sean :)
