The Things Stack exposes Prometheus metrics at the /metrics endpoint. This route is protected by Basic Auth with username metrics and password global.http.metrics.password.
To scrape these metrics, you can install Prometheus in the cluster. The installation details are outside the scope of this document.
The following scrape config can be used to scrape metrics from each of the components of The Things Stack.
scrape_configs:
- job_name: <name>
metrics_path: /metrics
scheme: http
basic_auth:
username: metrics
password: <password>
static_configs:
# This is the cluster local endpoint of the component's service.
- targets:
[
"<helm_release_name>-<component-name>.<namespace>.svc.cluster.local:1885",
]
For example, to scrape metrics from the Identity Servers of a The Things Stack deployment named mytts in the tts namespace, use the following.
scrape_configs:
- job_name: identity-server
metrics_path: /metrics
scheme: http
basic_auth:
username: metrics
password: <global.http.metrics.password>
static_configs:
- targets: ["mytts-is.tts.svc.cluster.local:1885"]
