default mailer handler fails in embedded ruby
Closed this issue · 5 comments
This is a cross post for the issue below since this is the right project. After following the install instructions, we're seeing that the default mailer plugin is throwing ruby errors from within the embedded ruby install. Note, installation is ubuntu 16.04 LTS.

Hi! Did you upgraded from a previous version of Sensu? Or is it a fresh install? If you just updated, you need to reinstall all your plugins as stated in the 0.29 changelog
IMPORTANT: Sensu packages now include Ruby 2.4.1. Upgrading from prior versions of Sensu will require any plugin or extension gems to be re-installed under the new Ruby environment.
Hi Augustin, I was working on a fresh ubuntu VM in this case. There were no prior installations. What i'm wondering is if there were fragments from a gem install without using the embedded binary.
Quite a few of the plugins do not yet support ruby 2.4 yet which will take some effort. I have not looked into if this works with 2.4 but I will try to get around to it when I have some time.
I completely misread this, apologies. Hmm that does not make much sense. Can you show me the output of /opt/sensu/embedded/bin gem search sensu-plugins-mailer?
