Checking cluster health

We can measure the health of our cluster by using the swift-dispersion-report tool. This is done by checking the set of our distributed containers to ensure that the objects are in their proper places within the cluster.

Getting ready

Ensure you are logged in to the swift-proxy nodes. If you created this node with Vagrant, you can access it by using the following command:

vagrant ssh swift-proxy

How to do it...

Carry out the following steps to set up the swift-dispersion tool to report on cluster health:

1. We create the configuration file (/etc/swift/dispersion.conf) required by the swift-dispersion tool, as follows:

   [dispersion] 
   auth_url = https://192.168.100.200:5000/v2.0
   auth_user = cookbook:admin
   auth_key = openstack
   auth_version = 2.0
   keystone_api_insecure = yes

   Tip

   We're using keystone_api_insecure in this environment because we are using a self-signed certificate for our keystone endpoint. This skips the validation of the certificate.

2. Now, we need to create containers...
