For service introduction visit README page and Overview of how vmanomaly works.

How to install and run vmanomaly

To run vmanomaly, you need to have VictoriaMetrics Enterprise license. You can get a trial license key here.

The following options are available:

• To run Docker image
• To run in Kubernetes with Helm charts

Note

: Starting from v1.13.0 there is a mode to keep anomaly detection models on host filesystem after fit stage (instead of keeping them in-memory by default); This may lead to noticeable reduction of RAM used on bigger setups. See instructions here.

Docker

To run vmanomaly, you need to have VictoriaMetrics Enterprise license. You can get a trial license key here.

Below are the steps to get vmanomaly up and running inside a Docker container:

1. Pull Docker image:

docker pull victoriametrics/vmanomaly:latest

2. (Optional step) tag the vmanomaly Docker image:

docker image tag victoriametrics/vmanomaly:latest vmanomaly

3. Start the vmanomaly Docker container with a license file, use the command below. Make sure to replace YOUR_LICENSE_FILE_PATH, and YOUR_CONFIG_FILE_PATH with your specific details:

export YOUR_LICENSE_FILE_PATH=path/to/license/file
export YOUR_CONFIG_FILE_PATH=path/to/config/file
docker run -it -v $YOUR_LICENSE_FILE_PATH:/license \
               -v $YOUR_CONFIG_FILE_PATH:/config.yml \
               vmanomaly /config.yml \
               --license-file=/license

In case you found PermissionError: [Errno 13] Permission denied: in vmanomaly logs, set user/user group to 1000 in the run command above / in a docker-compose file:

export YOUR_LICENSE_FILE_PATH=path/to/license/file
export YOUR_CONFIG_FILE_PATH=path/to/config/file
docker run -it --user 1000:1000 \
               -v $YOUR_LICENSE_FILE_PATH:/license \
               -v $YOUR_CONFIG_FILE_PATH:/config.yml \
               vmanomaly /config.yml \
               --license-file=/license

# docker-compose file
services:
  # ...
  vmanomaly:
    image: victoriametrics/vmanomaly:latest
    volumes:
        $YOUR_LICENSE_FILE_PATH:/license
        $YOUR_CONFIG_FILE_PATH:/config.yml
    command:
      - "/config.yml"
      - "--license-file=/license"
    # ...

For a complete docker-compose example please refer to our alerting guide, chapter docker-compose

Kubernetes with Helm charts

To run vmanomaly, you need to have VictoriaMetrics Enterprise license. You can get a trial license key here.

You can run vmanomaly in Kubernetes environment with these Helm charts.

How to configure vmanomaly

To run vmanomaly you need to set up configuration file in yaml format.

Here is an example of config file that will run Facebook Prophet model, that will be retrained every 2 hours on 14 days of previous data. It will generate inference (including anomaly_score metric) every 1 minute.

schedulers:
  2h_1m:
    # https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#periodic-scheduler
    class: 'periodic'
    infer_every: '1m'
    fit_every: '2h'
    fit_window: '2w'

models:
  # https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet
  prophet_model:
    class: "prophet"  # or "model.prophet.ProphetModel" until v1.13.0
    args:
      interval_width: 0.98

reader:
  # https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader
  datasource_url: "http://victoriametrics:8428/" # [YOUR_DATASOURCE_URL]
  sampling_period: "1m"
  queries: 
    # define your queries with MetricsQL - https://docs.victoriametrics.com/metricsql/
    cache: "sum(rate(vm_cache_entries))"

writer:
  # https://docs.victoriametrics.com/anomaly-detection/components/writer/#vm-writer
  datasource_url:  "http://victoriametrics:8428/" # [YOUR_DATASOURCE_URL]

Next steps:

• Define how often to run and make inferences in the scheduler section of a config file.
• Setup the datasource to read data from in the reader section.
• Specify where and how to store anomaly detection metrics in the writer section.
• Configure built-in models parameters according to your needs in the models section.
• Integrate your custom models with vmanomaly.
• Define queries for input data using MetricsQL.
