Define “sensu” in dashboard.json?

Whenever I have problems like this the first thing I recommend is to validate that every config file is valid json.


$ gem install jsonlint

Successfully installed jsonlint-0.2.0

Parsing documentation for jsonlint-0.2.0

Done installing documentation for jsonlint after 0 seconds

1 gem installed

And then search for .json files and validate them:


# remember to adjust the path you are searching and sudo if neccessary

find . -name '*.json' -exec jsonlint {} \;

Once you know you have valid json you can then take a closer look at your config.

{“timestamp”:“2018-01-24T19:11:00.726934+0530”,“level”:“fatal”,“message”:“sensu must be a hash”,“object”:[{“name”:“Datacenter 1”,“host”:“localhost”,“port”:4567}]}

You could try fixing it so that sensu loads them properly but I happen to know that is uchiwa config rather than sensu config meaning that it is in the wrong directory. Trying moving it out of /etc/sensu/conf.d/ into /etc/sensu/ which should not try to load that json file into its own config. That being said you should probably check to make sure its valid uchiwa config via its docs.
