ZMON's Python worker is doing the heavy lifting of executing tasks against entities, and evaluating all alerts assigned to check. Tasks are picked up from Redis and the resulting check values plus alert state changes are written back to Redis.
Start Redis on localhost:6379:
$ docker run -p 6379:6379 -it redis
Install the required development libraries:
$ sudo apt-get install build-essential python2.7-dev libpq-dev libldap2-dev libsasl2-dev libsnappy-dev libev4 libev-dev freetds-dev $ sudo pip2 install -r requirements.txt
$ brew install python snappy $ sudo pip install -r requirements.txt
Start the ZMON worker process:
$ python2 -m zmon_worker_monitor
You can query the worker monitor via the REST API:
$ curl http://localhost:8080/status
You can also query the worker monitor via RPC:
$ python2 -m zmon_worker_monitor.rpc_client http://localhost:23500/zmon_rpc list_stats
Running Unit Tests
Run tests via Tox.
You can also pass args to
tox, for instance to run specific test case:
$ tox tests/test_kairosdb.py::test_kairosdb_query
Alternative way of running unit tests within Docker:
$ export WORKER_IMAGE=registry.opensource.zalan.do/stups/zmon-worker:cd166 $ docker run -it -u $(id -u) -v $(pwd):/workdir -w /workdir $WORKER_IMAGE python setup.py flake8 $ docker run -it -u $(id -u) -v $(pwd):/workdir -w /workdir $WORKER_IMAGE python setup.py test
Building the Docker Image
$ docker build -t zmon-worker . $ docker run -it zmon-worker
Running the Docker image
The Docker image supports many configuration options via environment variables. Configuration options are explained in the ZMON Documentation.
