Infrastructure Integration

Configuration

  1. Configure the agent by editing /etc/nutanix/epoch-dd-agent/conf.d/dns_check.yamlin the collectors.

Example:

    init_config:
        default_timeout: 4
    instances:
        - name: example
          hostname: www.example.org
          # please notice: nameserver must be a valid IP address
          nameserver: 127.0.0.1
          timeout: 8

          # Specify an (optional) `record_type` to customize the record type
          # queried by the check (default: "A")
          # record_type: A

          # The check will automatically tag `nameserver` and `resolved_hostname`
          # Use this section to add additional tags
          #
          # tags:
          #   - tag:one
          #   - tag:two

        # If you use NXDOMAIN as the `record_type`, an NXDOMAIN result is expected from the query,
        # and the check instance will report response time data.
        # In many DNS systems, NXDOMAIN results are uncached. Further a query for a unqualified domain
        # name that one expects to return an NXDOMAIN result can result in many dns queries, depending
        # on the resolver's configured search domain.
        # For these reasons, these queries are good candidates to monitor the worst-case performance of a DNS lookup.
        # See https://github.com/DataDog/dd-agent/pull/2849 for more details.

        # - name: nxdomain_example
        #   hostname: nxdomain.example.org
        #   nameserver: 127.0.0.1
        #   record_type: NXDOMAIN
  1. Check and make sure that all yaml files are valid with following command:

    /etc/init.d/epoch-collectors configcheck
    
  2. Restart the Agent using the following command:

    /etc/init.d/epoch-collectors restart
    
  3. Execute the info command to verify that the integration check has passed:

    /etc/init.d/epoch-collectors info
