Monitor the resolvability of and lookup times for any DNS records using nameservers of your choosing.
The DNS check is packaged with the Agent, so simply install the Agent on any host from which you want to probe your DNS servers. Though many metrics-oriented checks are best run on the same host(s) as the monitored service, you may want to run this status-oriented check from hosts that do not run the monitored DNS services.
Create a file
dns_check.yaml in the Agent’s
conf.d directory. See the sample dns_check.yaml for all available configuration options:
init_config: instances: - name: Example (com) # nameserver: 126.96.36.199 # The nameserver to query, this must be an IP address hostname: example.com # the record to fetch # record_type: AAAA # default is A - name: Example (org) hostname: example.org
If you omit the
nameserver option, the check will use whichever nameserver is configured in local network settings.
Restart the Agent to begin sending DNS service checks and response times to Datadog.
Run the Agent’s
status subcommand and look for
dns_check under the Checks section:
Checks ====== [...] dns_check --------- - instance #0 [OK] - instance #1 [OK] - Collected 2 metrics, 0 events & 2 service checks [...]
The DNS check is compatible with all major platforms.
|The response time for DNS query for a given record, tagged by hostname, e.g. 'hostname:example.com'.
shown as second
The DNS check does not include any event at this time.
This agent check tags all service checks it collects with:
Returns CRITICAL if the Agent fails to resolve the request, otherwise returns UP.
