I add a chef mysqld receipt to the Vagrant file and here is the error from vagrant up:

    ==> default: Required argument password is missing!
    ==> default:
    ==> default: Cookbook Trace:

Solution: Add this to set the root_password:

chef.json = {
  :mysqld   => {
    :root_password => "test"
  }
}

Now you can connect to the mysql server by running

 mysql -u root -p 

This the error message:

    ==> default: Error executing action `enable` on resource 'sensu_service[sensu-client]'

It is because I did not include the sensu::default cookbook.

Reinstalling cask on another mac. Thought it is the command to install cask brew subcommand:

brew install cask

Wrong! This cask is actually an emacs package manager.

To install brew cask, it is the command:

brew tap caskroom/cask

I used chef to install sensu and ochiwa.

In the ocihwa log I see a lot of ‘connection refused’ error

{"Date":"2015-02-05T09:42:23.516606749Z","Level":"warning","Src":{"Func":"github.com/sensu/uchiwa/uchiwa.Build","Line":49},"Output":"API call to \"http://127.0.0.1:4567/stashes\" returned: Get http://127.0.0.1:4567/stashes: dial tcp 127.0.0.1:4567: connection refused"}

With help from sensu irc chatroom, I checked

netstat -anp | grep 4567

There is no process.

service sensu-api status

The service is stopped.

After starting the service, ochiwa can talk to sensu server now.

I have originally created a template hello_world. Then I renamed it to sayhi. Somehow the Template Slug stays as hello-world: in the webhook payload the template name carries hello-world instead of the new name sayhi
