End-To-End tests
GitHub reference: contrib/end2end
This directory holds scripts and configuration for end-to-end tests of the observability volume controller. The end-to-end tests are based upon local set-ups of two use cases:
- prometheus at the edges and thanos at the hub
- oTel collector at the edges and prometheus at the hub
Use case (1): prometheus at the edges and thanos at the hub
To manually start e2e containers, use make up-prom-thanos
To shut down the containers, use: make down-prom-thanos
The setup automatically starts the following containers:
What does it start?
| Service | Ports | |
|---|---|---|
| prometheus_one | The first Prometheus server | 9001 |
| prometheus_two | The second Prometheus server | 9002 |
| minio | A minio instance serving as Object Storage for store, compactor and sidecars | 9000 |
| minio-console | user: myaccesskey password: mysecretkey | 9007 |
| thanos_sidecar_one | First Thanos sidecar for prometheus_one | |
| thanos_sidecar_two | Second Thanos sidecar for prometheus_two | |
| thanos_querier | Thanos querier instance connected to both sidecars and Thanos store | 10902 |
| thanos_query_frontend | Thanos query frontend connected to querier | 19090 |
| thanos_store | A Thanos store instance connected to minio | 10912 |
query examples
For example, to get the go_memstats_frees_total metric values
from time stamp 1711895548 to timestamp 171189954 in steps of 560s execute the query:
curl 'http://localhost:19090/api/v1/query_range?query=go_memstats_frees_total&start=1711895548&end=1711899548&step=560s' | jq
Use case (2): oTel collector at the edges and prometheus at the hub
To manually start e2e containers, use make up-otel-prom
To shut down the containers, use: make down-otel-prom
The setup automatically starts the following containers:
What does it start?
| Service | Ports | |
|---|---|---|
| prometheus_hub | A Prometheus instance | 9001 |
| otel_collector_one | The first otel collector instance | 18888 |
| otel_collector_two | The second collector instance | 18889 |
