Prometheus is the open source monitoring system and time series database. WCS supports Prometheus metric format since build 5.2.416, no WCS setup is needed to integrate with Prometheus monitoring.
To set up Prometheus to collect WCS metrics, the following scrape configuration should be described in prometheus.yml
scrape_configs:
- job_name: 'flashphoner'
metrics_path: '/'
params:
action: [stat]
format: [prometheus]
static_configs:
- targets: ['WCS_address:8081']
Where
- WCS_address - WCS server address
- 8081 - WCS server port to request metrics
As a result, Prometheus should form the following query
http://WCS_address:8081/?action=stat&format=prometheus
and receive WCS statistics metrics in its format.
Since build 5.2.518, metrics of published streams can be requested by the following query
http://WCS_address:8081/?action=stat&format=prometheus&groups=publish_streams
