Hi All,

I am working on moving Nagios to Sensu. What is the plugin that can replace check\_tcp plugin for Sensu.

Thanks for the help.

You can use your existing check\_tcp plugin. Sensu uses the same output format as Nagios, and supports its plugins.

Hi Nathan,

Sensu uses the Nagios check plugin format/spec, so you should be able to use your Nagios plugins. The community repo does have a plugin called check-banner.rb, that most likely does what you’re looking for, as an alternative.

You can also call out directly to commands in theory, e.g. your check is just:

ping -c 1 8.8.8.8 -W 1

Granted the output error might not be the most friendly, but it should work.
