DNSmetrics connects to your accounts at multiple managed DNS providers using their APIs and emits standardized metrics in statsd format for easy ingestion into your monitoring solution of choice.

DNSmetrics connects to your accounts at multiple managed DNS providers using their APIs and emits standardized metrics in statsd format for easy ingestion into your monitoring solution of choice.

While any DNS provider has a control panel, their UI can be incomplete and they might not have alerting on metrics that are important to you. Furthermore, if you use several providers for redundancy, there is no way to have one dashboard that shows unified health of your DNS architecture.

Supported DNS providers

• Dyn
• NS1

It is easy to add new providers. Contributions are most welcome.

Installation

With Go 1.7 installed, do make install and this will result in a binary.

Configuration

Take a look at config.yml. It should be self explanatory.

Running DNSmetrics

For testing, using --once will output the collected metrics to stdout instead of sending them to statsd. Without --once, DNSmetrics will run as a service, collecting and sending metrics every check_interval.

List of Metrics

All metrics are tagged with zone and provider tags. Zone is the DNS zone for the metric and provider is the DNS provider.

All metrics have the prefix dnsmetrics.

Not all providers support all metrics described below.

• zone.type.primary, zone.type.secondary - 0 or 1.

• zone.qps - current (or most recent) rate of queries per second, of all types, for the zone.

• zone.record_count - number of records of all types in the zone.

• zone.serial - the serial number of the zone.

• zone.secondary.is_ok - 0 or 1. 1 when provider considers the zone to be healthy.

• zone.secondary.is_expired - 0 or 1. 1 when the zone is expired and presumably no longer being served by the provider.

• zone.secondary.sec_since_last_xfr - time since last zone transfer.

Monitoring

A DataDog dashboard specification with some of the collected metrics can be found in monitoring/datadog. It can be imported using the API.
