configuration

Needs only url to kubelet metric-address.

Here is an example:

jobs:
  - name: local
    url : http://127.0.0.1:10255/metrics
      
  - name: remote
    url : http://100.64.0.1:10255/metrics

For all available options please see module configuration file.

Without configuration, module attempts to connect to http://127.0.0.1:10255/metrics
