Having Problems with mailer.rb

[Tony]

Hi All,

I wonder if anyone can help me. I am trying to setup mailer.rb as per this document: http://sensuapp.org/docs/0.16/adding_a_handler

Configuration

OS: CentOS 7 x86_64

SENSU VERSION 0.17.0

I have followed the steps but cant seem to get it to work without an error. I have set sensu to use the embedded ruby version in /etc/sensu/default and dowloaded the mail gem to embedded ruby.

I have created a test log entry and am seeing the following:

[root@ln01 ~]# cat ./test.log | /opt/sensu/embedded/bin/ruby -d/etc/sensu/handlers/mailer.rb

I hope someone can help as this is driving me up the wall. I am also not overly familiar with Ruby. Thanks for any replies in advance!

The -d debug flag is giving you (probably) more information than you
want. Most of that is red-herrings.

But the test.log file probably doesn't have valid event data to
operate on. The handler isn't doing good input validation at this
stage, so it is blowing up on the lack of @event['client']['name']

Can you pastebin your test.log? Better yet can you paste an error
"closer" to the real-life working of the handler, like from the
sensu-server log?
