For service introduction visit [README](https://docs.victoriametrics.com/anomaly-detection/) page
and [Overview](https://docs.victoriametrics.com/anomaly-detection/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**](https://victoriametrics.com/products/enterprise/trial/).
The following options are available:
- [To run Docker image](#docker)
- [To run in Kubernetes with Helm charts](#kubernetes-with-helm-charts)
> **Note**: Starting from [v1.13.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1130) 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](https://docs.victoriametrics.com/anomaly-detection/faq/#resource-consumption-of-vmanomaly).
### Docker
> To run `vmanomaly`, you need to have VictoriaMetrics Enterprise license. You can get a trial license key [**here**](https://victoriametrics.com/products/enterprise/trial/).
Below are the steps to get `vmanomaly` up and running inside a Docker container:
1. Pull Docker image:
```sh
docker pull victoriametrics/vmanomaly:v1.16.1
```
2. (Optional step) tag the `vmanomaly` Docker image:
```sh
docker image tag victoriametrics/vmanomaly:v1.16.1 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**:
```sh
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 \
--licenseFile=/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:
```sh
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 \
--licenseFile=/license
```
```yaml
# docker-compose file
services:
# ...
vmanomaly:
image: victoriametrics/vmanomaly:v1.16.1
volumes:
$YOUR_LICENSE_FILE_PATH:/license
$YOUR_CONFIG_FILE_PATH:/config.yml
command:
- "/config.yml"
- "--licenseFile=/license"
# ...
```
For a complete docker-compose example please refer to [our alerting guide](https://docs.victoriametrics.com/anomaly-detection/guides/guide-vmanomaly-vmalert/), chapter [docker-compose](https://docs.victoriametrics.com/anomaly-detection/guides/guide-vmanomaly-vmalert/#docker-compose)

### Kubernetes with Helm charts
> To run `vmanomaly`, you need to have VictoriaMetrics Enterprise license. You can get a trial license key [**here**](https://victoriametrics.com/products/enterprise/trial/).
You can run `vmanomaly` in Kubernetes environment
with [these Helm charts](https://github.com/VictoriaMetrics/helm-charts/blob/master/charts/victoria-metrics-anomaly/README.md).
## 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](https://facebook.github.io/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.
```yaml
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](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/) section of a config file.
- Setup the datasource to read data from in the [reader](https://docs.victoriametrics.com/anomaly-detection/components/reader/) section.
- Specify where and how to store anomaly detection metrics in the [writer](https://docs.victoriametrics.com/anomaly-detection/components/writer/) section.
- Configure built-in models parameters according to your needs in the [models](https://docs.victoriametrics.com/anomaly-detection/components/models/) section.
- Integrate your [custom models](https://docs.victoriametrics.com/anomaly-detection/components/models/#custom-model-guide) with `vmanomaly`.
- Define queries for input data using [MetricsQL](https://docs.victoriametrics.com/metricsql/).
