There are 2 models to monitor VictoriaMetrics Anomaly Detection behavior - [push](https://docs.victoriametrics.com/keyconcepts/#push-model) and [pull](https://docs.victoriametrics.com/keyconcepts/#pull-model). Parameters for each of them should be specified in the config file, `monitoring` section.

> **Note**: there was an enhancement of [self-monitoring](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#metrics-generated-by-vmanomaly) metrics for consistency across the components ([v.1.17.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1170)). Documentation was updated accordingly. Key changes included:
- Converting several [self-monitoring](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#metrics-generated-by-vmanomaly) metrics from `Summary` to `Histogram` to enable quantile calculation. This addresses the limitation of the `prometheus_client`'s [Summary](https://prometheus.github.io/client_python/instrumenting/summary/) implementation, which does not support quantiles. The change ensures metrics are more informative for performance analysis. Affected metrics are:
    - `vmanomaly_reader_request_duration_seconds` ([VmReader](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#reader-behaviour-metrics))
    - `vmanomaly_reader_response_parsing_seconds` ([VmReader](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#reader-behaviour-metrics))
    - `vmanomaly_writer_request_duration_seconds` ([VmWriter](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#writer-behaviour-metrics))
    - `vmanomaly_writer_request_serialize_seconds` ([VmWriter](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#writer-behaviour-metrics))
- Adding a `query_key` label to the `vmanomaly_reader_response_parsing_seconds` [metric](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#reader-behaviour-metrics) to provide finer granularity in tracking the performance of individual queries. This metric has also been switched from `Summary` to `Histogram` to align with the other metrics and support quantile calculations.
- Adding `preset` and `scheduler_alias` keys to [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#reader-behaviour-metrics) and [VmWriter](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#writer-behaviour-metrics) metrics for consistency in multi-[scheduler](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/) setups.
- Renaming [Counters](https://prometheus.io/docs/concepts/metric_types/#counter) `vmanomaly_reader_response_count` to `vmanomaly_reader_responses` and `vmanomaly_writer_response_count` to `vmanomaly_writer_responses`.

## mTLS protection

Starting from [v1.16.3](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1163), `vmanomaly` components such as [VmWriter](https://docs.victoriametrics.com/anomaly-detection/components/writer/#vm-writer) support [mTLS](https://en.wikipedia.org/wiki/Mutual_authentication) to ensure secure communication with [VictoriaMetrics Enterprise, configured with mTLS](https://docs.victoriametrics.com/#mtls-protection).

For detailed guidance on configuring mTLS parameters such as `verify_tls`, `tls_cert_file`, and `tls_key_file`, please refer to the [mTLS protection section](https://docs.victoriametrics.com/anomaly-detection/components/reader/#mtls-protection) in the [Reader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) documentation. The configuration principles apply consistently across all these `vmanomaly` components.

### Models Behaviour Metrics
Label names [description](#labelnames)

> **Note**: There is a new label key `model_alias` introduced in multi-model support [v1.10.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1100). This label key adjustment was made to preserve unique label set production during writing produced metrics back to VictoriaMetrics.

> **Note**: as a part of [self-monitoring](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#metrics-generated-by-vmanomaly) metrics enchancement ([v.1.17.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1170)), new metrics, like `vmanomaly_model_run_errors`, was added. Some of them changed the type (`Summary` -> `Histogram`), like `vmanomaly_model_run_duration_seconds`.

Also, metrics `vmanomaly_writer_request_duration_seconds` and `vmanomaly_writer_request_serialize_seconds` changed their type to `Histogram` (was `Summary` prior to [v1.17.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1170)).
