To try and use local docker prometheus setup on MacOS or Windows, you have to install Docker Desktop from https://docs.docker.com/get-started/ If you want to install individual componenets, then Docker CE and docker-compose are the prerequisites.
Simply execute ./docker.sh and you'll get following setup:
- prometheus, reachable on port 9090, with configuration under
./prometheus/etc - alertmanager, reachable on port 9093, with configuration under
./alertmanager/etc - 3x node exporters, already configured in prometheus for scraping on port 9100, with custom file-based metrics examples, located under
./node_exporter/client-\*/, where the client's name matches the name in docker. It's not necessary to restart the setup after you change the custom metrics files.
Preconfigured is simple example with fake_load metrics (per host), alert thresholds (under node_exporter/client-b1/limits.prom) in prometheus and you can see the results either under prometheus or in alertmanager.
- Prometheus is http://localhost:9090/
- Alertmanager is http://localhost:9093/
Create your test files under prometheus/etc/tests (see example load.yml in this directory) and simply run ./run-tests.sh [filename.yml ...], eg. ./run-tests.sh load.yml. If you do not specify filename, then all files matching prometheus/etc/tests/\*.yml will be tested.
