## Metrics
|
|
|
|
If enabled in the [Metrics section][metrics feature] in the configuration file,
|
|
[Statsd][statsd] compatible metrics are available to use:
|
|
|
|
| Name | Type | Description |
|
|
| ------------------------------------------------ | ------- | ----------- |
|
|
| zonemaster.rpcapi.requests.\<METHOD>.\<STATUS> | Counter | Number of times the JSON RPC method \<METHOD> resulted in JSON RPC status \<STATUS>. The status is represented in string, possible values are: `RPC_PARSE_ERROR`, `RPC_INVALID_REQUEST`, `RPC_METHOD_NOT_FOUND`, `RPC_INVALID_PARAMS`, `RPC_INTERNAL_ERROR`. |
|
|
| zonemaster.testagent.tests_started | Counter | Number of tests that have started. |
|
|
| zonemaster.testagent.tests_completed | Counter | Number of tests that have been completed successfully. |
|
|
| zonemaster.testagent.tests_died | Counter | Number of tests that have died. |
|
|
| zonemaster.testagent.tests_duration_seconds | Timing | The duration of a test, emitted for each test. |
|
|
| zonemaster.testagent.cleanup_duration_seconds | Timing | Time spent to kill timed out processes. |
|
|
| zonemaster.testagent.fetchtests_duration_seconds | Timing | Time spent selecting the next text to run and processing unfinished tests. |
|
|
| zonemaster.testagent.running_processes | Gauge | Number of running processes in a test agent. |
|
|
| zonemaster.testagent.maximum_processes | Gauge | Maximum number of running processes in a test agent. |
|
|
|
|
|
|
### Usage
|
|
|
|
Testing the metrics feature can be as easy as running a listening UDP server like
|
|
|
|
```sh
|
|
ns -lup 8125
|
|
```
|
|
|
|
This should be enough to see the metrics emitted by Zonemaster.
|
|
|
|
More complex setups are required for the metrics to be used in alerts and dashboards.
|
|
StatsD metrics can be integrated to a number of metrics backend like Prometheus (using the [StatsD exporter]), InfluxDB (using Telegraf and the [StatsD plugin]), Graphite ([integration guide]) and others.
|
|
|
|
#### StatsD Exporter (Prometheus)
|
|
|
|
1. Download the binary (tar file) corresponding to your environment https://github.com/prometheus/statsd_exporter/releases
|
|
2. Untar the file
|
|
3. `cd` into the statsd_exporter directory
|
|
4. Create a `statsd_mapping.yml` file with content as below
|
|
```yml
|
|
mappings:
|
|
- match: zonemaster.rpcapi.requests.*.*
|
|
name: zonemaster_rpcapi_requests_total
|
|
labels:
|
|
method: $1
|
|
status: $2
|
|
- match: zonemaster.testagent.tests_duration_seconds
|
|
observer_type: histogram
|
|
buckets: [ 1, 2.5, 5, 10, 15, 30, 45, 60, 75, 90, 105, 120, 150, 180]
|
|
name: zonemaster_testagent_tests_duration_seconds
|
|
- match: zonemaster.testagent.cleanup_duration_seconds
|
|
observer_type: histogram
|
|
buckets: [ 0.01, 0.025, 0.05, 0.075, 0.1, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2]
|
|
name: zonemaster_testagent_cleanup_duration_seconds
|
|
- match: zonemaster.testagent.fetchtests_duration_seconds
|
|
observer_type: histogram
|
|
buckets: [ 0.001, 0.0025, 0.005, 0.0075, 0.01, 0.025, 0.05, 0.075, 0.1, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 3, 5, 10]
|
|
name: zonemaster_testagent_fetchtests_duration_seconds
|
|
```
|
|
5. Run it like
|
|
```
|
|
./statsd_exporter --statsd.mapping-config=./statsd_mapping.yml --statsd.listen-udp=:8125 --statsd.listen-tcp=:8125
|
|
```
|
|
6. Run the following to see Zonemaster metrics:
|
|
```
|
|
curl localhost:9102/metrics | grep zonemaster
|
|
```
