Please find the changelog for VictoriaMetrics Anomaly Detection below.
## v1.17.0
Released: 2024-10-17
- FEATURE: Added `max_points_per_query` (global and [query-specific](https://docs.victoriametrics.com/anomaly-detection/components/reader/#per-query-parameters)) [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) arg to control query chunking. This overrides how `search.maxPointsPerTimeseries` flag (introduced in [v1.14.1](#v1141)) is used in `vmanomaly` for splitting long `fit_window` queries into smaller sub-intervals. This helps users avoid hitting the `search.maxQueryDuration` limit for individual queries by distributing initial query across multiple subquery requests with minimal overhead.
- IMPROVEMENT: Enhanced the [self-monitoring](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#metrics-generated-by-vmanomaly) metrics for consistency across the components. Key changes include:
- Converted 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))
- Added 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.
- Added `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.
- Renamed [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`.
- Updated [docs](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#metrics-generated-by-vmanomaly) for better clarity.
- IMPROVEMENT: Accelerated performance of model fitting stages on multicore systems.
- IMPROVEMENT: Optimized query handling in multi-[scheduler](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/) setups by filtering [queries](https://docs.victoriametrics.com/anomaly-detection/components/models/#queries) for each scheduler based on model requirements. This reduces unnecessary data fetching from VictoriaMetrics, ensuring only relevant queries are processed by the [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader#vm-reader), leading to better performance and efficiency of configs with multiple active schedulers.
- IMPROVEMENT: Implemented automatic cleanup of files in subdirectories within `/tmp` ([generated by the Stan backend](https://mc-stan.org/cmdstanpy/users-guide/outputs.html) when utilizing [Prophet](https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet) models) after each `fit` operation. This prevents the accumulation of unused data over time in `/tmp`, addressing a potential issue where these files would only be deleted upon termination of the current Python session or service, leading to uncontrolled disk growth.
- FIX: Re-enable the `vmanomaly_reader_response_count` (now called `vmanomaly_reader_responses`) self-monitoring [metric](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#reader-behaviour-metrics) for the [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader), which was unintentionally disabled in previous releases and now updates correctly as intended.
## v1.16.3
Released: 2024-10-08
- IMPROVEMENT: Added `tls_cert_file` and `tls_key_file` arguments to support mTLS (mutual TLS) in `vmanomaly` components. This enhancement applies to the following components: [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader), [VmWriter](https://docs.victoriametrics.com/anomaly-detection/components/writer/#vm-writer), and [Monitoring/Push](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#push-config-parameters). You can also use these arguments in conjunction with `verify_tls` when it is set as a path to a custom CA certificate file.

## Handling large queries in vmanomaly
If you're dealing with a large query in the `queries` argument of [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) (especially when running [within a scheduler using a long](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/?highlight=fit_window#periodic-scheduler) `fit_window`), you may encounter issues such as query timeouts (due to the `search.maxQueryDuration` server limit) or rejections (if the `search.maxPointsPerTimeseries` server limit is exceeded).
We recommend upgrading to [v1.17.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1170), which introduced the `max_points_per_query` argument (both global and [query-specific](https://docs.victoriametrics.com/anomaly-detection/components/reader/#per-query-parameters)) for the [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader). This argument overrides how `search.maxPointsPerTimeseries` flag handling (introduced in [v1.14.1](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1141)) is used in `vmanomaly` for splitting long `fit_window` queries into smaller sub-intervals. This helps users avoid hitting the `search.maxQueryDuration` limit for individual queries by distributing initial query across multiple subquery requests with minimal overhead.
By splitting long `fit_window` queries into smaller sub-intervals, this helps avoid hitting the `search.maxQueryDuration` limit, distributing the load across multiple subquery requests with minimal overhead. To resolve the issue, reduce `max_points_per_query` to a value lower than `search.maxPointsPerTimeseries` until the problem is gone:
```yaml
reader:
# other reader args
max_points_per_query: 10000 # reader-level constraint
queries:
sum_alerts:
expr: 'sum(ALERTS{alertstate=~'(pending|firing)'}) by (alertstate)'
max_points_per_query: 5000 # query-level override
models:
prophet:
# other model args
queries: [
'sum_alerts',
]
# other config sections
```
### Alternative workaround for older versions
If upgrading is not an option, you can partially address the issue by splitting your large query into smaller ones using appropriate label filters:
For example, such query
```yaml
reader:
# other reader args
queries:
sum_alerts:
expr: 'sum(ALERTS{alertstate=~'(pending|firing)'}) by (alertstate)'
models:
prophet:
# other model args
queries: [
'sum_alerts',
]
# other config sections
```
can be modified to:
```yaml
reader:
# other reader args
queries:
sum_alerts_pending:
expr: 'sum(ALERTS{alertstate='pending'}) by ()'
sum_alerts_firing:
expr: 'sum(ALERTS{alertstate='firing'}) by ()'
models:
prophet:
# other model args
queries: [
'sum_alerts_pending',
'sum_alerts_firing',
]
# other config sections
```
Please note that this approach may not fully resolve the issue if subqueries are not evenly distributed in terms of returned timeseries. Additionally, this workaround is not suitable for queries used in [multivariate models](https://docs.victoriametrics.com/anomaly-detection/components/models#multivariate-models) (especially when using the [groupby](https://docs.victoriametrics.com/anomaly-detection/components/models/#group-by) argument).
## Scaling vmanomaly
> **Note:** As of latest release we do not support cluster or auto-scaled version yet (though, it's in our roadmap for - better backends, more parallelization, etc.), so proposed workarounds should be addressed *manually*.

- **High anomaly scores** (>1) when the *data falls outside the expected range*, indicating a data constraint violation.
- **Lowest anomaly scores** (=0) when the *model's predictions (`yhat`) fall outside the expected range*, meaning uncertain predictions.
- `max_points_per_query` (int): Introduced in [v1.17.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1170), optional arg overrides how `search.maxPointsPerTimeseries` flag (available since [v1.14.1](#v1141)) impacts `vmanomaly` on splitting long `fit_window` [queries](https://docs.victoriametrics.com/anomaly-detection/components/reader/?highlight=queries#vm-reader) into smaller sub-intervals. This helps users avoid hitting the `search.maxQueryDuration` limit for individual queries by distributing initial query across multiple subquery requests with minimal overhead. Set less than `search.maxPointsPerTimeseries` if hitting `maxQueryDuration` limits. If set on a query-level, it overrides the global `max_points_per_query` (reader-level).
### Per-query config example
```yaml
reader:
class: 'vm'
sampling_period: '1m'
max_points_per_query: 10000
# other reader params ...
queries:
ingestion_rate:
expr: 'sum(rate(vm_rows_inserted_total[5m])) by (type) > 0'
step: '2m' # overrides global `sampling_period` of 1m
data_range: [10, 'inf'] # meaning only positive values > 10 are expected, i.e. a value `y` < 10 will trigger anomaly score > 1
max_points_per_query: 5000 # overrides reader-level value of 10000 for `ingestion_rate` query

Introduced in [v1.15.1](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1151), it allows overriding the default `-search.latencyOffset` [flag of VictoriaMetrics](https://docs.victoriametrics.com/?highlight=search.latencyOffset#list-of-command-line-flags) (30s). The default value is set to 1ms, which should help in cases where `sampling_frequency` is low (10-60s) and `sampling_frequency` equals `infer_every` in the [PeriodicScheduler](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/?highlight=infer_every#periodic-scheduler). This prevents users from receiving `service - WARNING - [Scheduler [scheduler_alias]] No data available for inference.` warnings in logs and allows for consecutive `infer` calls without gaps. To restore the old behavior, set it equal to your `-search.latencyOffset` [flag value]((https://docs.victoriametrics.com/?highlight=search.latencyOffset#list-of-command-line-flags)).

<!-- ### mTLS protection
Starting from [v1.16.3](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1163), `vmanomaly` supports [mTLS](https://en.wikipedia.org/wiki/Mutual_authentication) requests in its components, like [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader), [VmWriter](https://docs.victoriametrics.com/anomaly-detection/components/writer/#vm-writer), and [Monitoring/Push](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#push-config-parameters) to query from and write to [VictoriaMetrics Enterprise, configured in the same mode](https://docs.victoriametrics.com/#mtls-protection).
Please see the description of next arguments in a [config](#config-parameters):
- `verify_tls` (if string, acts similar to `-mtlsCAFile` command line arg of VictoriaMetrics).

### mTLS protection
As of [v1.16.3](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1163), `vmanomaly` supports [mutual TLS (mTLS)](https://en.wikipedia.org/wiki/Mutual_authentication) for secure communication across its components, including [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader), [VmWriter](https://docs.victoriametrics.com/anomaly-detection/components/writer/#vm-writer), and [Monitoring/Push](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#push-config-parameters). This allows for mutual authentication between the client and server when querying or writing data to [VictoriaMetrics Enterprise, configured for mTLS](https://docs.victoriametrics.com/#mtls-protection).
