### Describe Your Changes

Some messages were written to `stdout` using `fmt.Printf` and
`fmt.Println`, while the other messages like import statistics were
written to `stderr` through the `log` package.

This led to ordering problems where the `Import finished!` +
`VictoriaMetrics importer stats` messages, which expected to be the last
messages, appeared before `Continue import process with filter`
messages, creating confusing output for users.

```

 Please find the changelog for VictoriaMetrics Anomaly Detection below.
 
+## v1.25.3
+Released: 2025-08-19
+
+- FEATURE: Added forecasting capabilities to the [`ProphetModel`](https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet) this allows users to generate *future* (point-wise and interval) predictions with offsets defined by `forecast_at` argument (e.g. `['1d', '1w']`) at *current* timestamp and store these in respective series, e.g. `yhat_1d`, `yhat_lower_1d`, `yhat_upper_1d`, etc. This feature is particularly useful for scenarios where future predictions are needed, such as capacity planning or trend analysis. See [FAQ](https://docs.victoriametrics.com/anomaly-detection/faq/#forecasting) for more details.
+
+- IMPROVEMENT: Added `logger_levels` argument to `settings` [config section](https://docs.victoriametrics.com/anomaly-detection/components/settings/#logger-levels) to allow setting specific log levels for individual components. Useful for debugging specific components. For example, `logger_levels: { "reader.vm": "DEBUG" }` will set the log level for the `VmReader` component to `DEBUG`, while leaving other components at their default log levels. Also is supported in [hot reload](https://docs.victoriametrics.com/anomaly-detection/components/#hot-reload) mode, allowing for dynamic log level changes without service restarts.
+
+- IMPROVEMENT: Added logging of URLs used for querying VictoriaMetrics TSDB in [`VmReader`](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) to ease the debugging of incomplete data retrieval, incorrect endpoints, or misconfigured tenant IDs. The URLs are logged at the `DEBUG` level, so you can control their verbosity using the `--loggerLevelComponents` argument with `reader.vm=DEBUG` or `reader=DEBUG` to see the URLs in the logs.
+
+- IMPROVEMENT: Added `offset` [argument](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) to `VmReader` on reader and query levels to allow for flexible time offset adjustments in the reader. Useful for correcting for data collection delays. The `offset` can be specified as a string (e.g., "15s", "-20s") and will be applied to all queries processed by the reader. See [FAQ](https://docs.victoriametrics.com/anomaly-detection/faq/#using-offsets) for more details.
+
+- BUGFIX: Resolved the issue where symlink-ed configuration files were not properly processed by [hot reload](https://docs.victoriametrics.com/anomaly-detection/components/#hot-reload) mechanism, leading to the service not picking up changes made to the original files. Now it properly resolves symlinks and reloads the configuration when the original file is modified.

 ## Handling noisy input data
 `vmanomaly` operates on data fetched from VictoriaMetrics using [MetricsQL](https://docs.victoriametrics.com/victoriametrics/metricsql/) queries, so the initial data quality can be fine-tuned with aggregation, grouping, and filtering to reduce noise and improve anomaly detection accuracy.
 
+## Using offsets
+`vmanomaly` supports {{% available_from "v1.25.3" anomaly %}} the use of offsets in the [`reader`](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) section to adjust the time range of the data being queried. This can be particularly useful for correcting for data collection delays or other timing issues. It can be also defined or overridden on [per-query basis](https://docs.victoriametrics.com/anomaly-detection/components/reader/#per-query-parameters).
+
+For example, if you want to query data with a 60-second delay (e.g. data collection happened 1 sec ago, however, timestamps written to VictoriaMetrics are 60 seconds in the past), you can set the `offset` argument to `-60s` in the reader section:
+
+```yaml
+reader:
+  class: 'vm'
+  datasource_url: 'http://localhost:8428'
+  sampling_period: '10s'
+  offset: '-60s'
+  queries:
+    vmb:
+      expr: 'avg(vm_blocks)'
+    cpu_custom_offset:
+      expr: 'avg(rate(vm_cpu_usage[5m]))'
+      offset: '-30s'  # this will override the global offset for this query only
+```
+
 ## Handling timezones
 
 `vmanomaly` supports timezone-aware anomaly detection {{% available_from "v1.18.0" anomaly %}} through a `tz` argument, available both at the [reader level](https://docs.victoriametrics.com/anomaly-detection/components/reader#vm-reader) and at the [query level](https://docs.victoriametrics.com/anomaly-detection/components/reader/#per-query-parameters).

+Once anomaly scores are written back to VictoriaMetrics, you can use [MetricsQL](https://docs.victoriametrics.com/victoriametrics/metricsql/) expressions subset in `vmalert` to define alerting rules based on these scores. Reasonable defaults are `anomaly_score > 1`:

+      description: "Anomaly score is {{ $value }} for query {{ $labels.for }}. Value: {{ $value }}."
+```
+
 ## Preventing alert fatigue
 Produced anomaly scores are designed in such a way that values from 0.0 to 1.0 indicate non-anomalous data, while a value greater than 1.0 is generally classified as an anomaly. However, there are no perfect models for anomaly detection, that's why reasonable defaults expressions like `anomaly_score > 1` may not work 100% of the time. However, anomaly scores, produced by `vmanomaly` are written back as metrics to VictoriaMetrics, where tools like [`vmalert`](https://docs.victoriametrics.com/victoriametrics/vmalert/) can use [MetricsQL](https://docs.victoriametrics.com/victoriametrics/metricsql/) expressions to fine-tune alerting thresholds and conditions, balancing between avoiding [false negatives](https://victoriametrics.com/blog/victoriametrics-anomaly-detection-handbook-chapter-1/#false-negative) and reducing [false positives](https://victoriametrics.com/blog/victoriametrics-anomaly-detection-handbook-chapter-1/#false-positive).

+## Forecasting
+
+Not intended for forecasting in its core, `vmanomaly` can still be used to produce forecasts using [ProphetModel](https://docs.victoriametrics.com/anomaly-detection/components/models#prophet) {{% available_from "v1.25.3" anomaly %}}, which can be helpful in scenarios like capacity planning, resource allocation, or trend analysis, if the underlying data is complex and can't be handled by inline MetricsQL queries, including [predict_linear](https://docs.victoriametrics.com/victoriametrics/metricsql/#predict_linear).
+
+> However, please note that this mode should be used with care, as the model will produce `yhat_{h}` (and probably `yhat_lower_{h}`, and `yhat_upper_{h}`) time series **for each timeseries returned by input queries and for each forecasting horizon specified in `forecast_at` argument, which can lead to a significant increase in the number of active timeseries in VictoriaMetrics TSDB**.
+
+Here's an example of how to produce forecasts using `vmanomaly` and combine it with the regular model, e.g. to estimate daily outcomes for a disk usage metric:
+
+```yaml

 ## Resource consumption of vmanomaly
 `vmanomaly` itself is a lightweight service, resource usage is primarily dependent on [scheduling](https://docs.victoriametrics.com/anomaly-detection/components/scheduler) (how often and on what data to fit/infer your models), [# and size of timeseries returned by your queries](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader), and the complexity of the employed [models](https://docs.victoriametrics.com/anomaly-detection/components/models). Its resource usage is directly related to these factors, making it adaptable to various operational scales. Various optimizations are available to balance between RAM usage, processing speed, and model capacity. These options are described in the sections below.

For example, if `forecast_at` is set to `['1h', '1d']`, the model will produce forecasts for both the next hour and the next day, and these series can be accessed by `yhat_1h`, `yhat_lower_1h`, `yhat_upper_1h`, `yhat_1d`, `yhat_lower_1d`, and `yhat_upper_1d` in the output, respectively. See [FAQ](https://docs.victoriametrics.com/anomaly-detection/faq/#forecasting) for more details.
+
+> `forecast_at` parameter can lead to **significant increase in active timeseries** if you have a lot of time series returned by your queries, as it will produce additional series for each of the future timestamps specified in `forecast_at` (optionally multiplied by 1-3 if interval forecasts are included). For example, if you have 1000 time series returned by your query and set `forecast_at` to `[1h, 1d, 1w]`, and `provide_series` includes `yhat_lower` and `yhat_upper`, it will produce 1000 (series) * 3 (intervals) * 3 (predictions, point + interval) = 9000 additional timeseries. Consider using it only on small subset of metrics (e.g. grouped by `host` or `region`) to avoid this issue, as it also **proportionally (to the number of `forecast_at` elements) increases the timings of inference calls**.

+### Logger Levels
+
+{{% available_from "v1.25.3" anomaly %}} `vmanomaly` service supports per-component logger levels, allowing to control the verbosity of logs for each component independently. This can be useful for debugging or monitoring specific components without overwhelming the logs with information from other components. Prefixes are also supported, allowing to set the logger level for all components with a specific prefix.
+
+The logger levels can be set in the `settings` section of the config file under `logger_levels` key, where the key is the component name or prefix and the value is the desired logger level. The available logger levels are: `debug`, `info`, `warning`, `error`, and `critical`.
+
+> Best used in combination with [hot-reload](https://docs.victoriametrics.com/anomaly-detection/components/#hot-reload) to change the logger levels *on-the-fly* without restarting the service through a short-circuit config check than doesn't even trigger the state restoration logic.
+
+Here's an example configuration that sets the logger level for the `reader` component to `debug` and for the `writer` component to `critical`, while `--loggerLevel` [command line argument](https://docs.victoriametrics.com/anomaly-detection/quickstart/#command-line-arguments) sets the default logger level to `INFO` for all (the other) components, unless overridden by the config:
+
+> If commented out in hot-reload mode during hot-reload event, the logger level for the component will be set back to what `--loggerLevel` command line argument is set to, which defaults to `info` if not specified.
+
+```yaml
+settings:
+  n_workers: 4
+  restore_state: True  # enables state restoration
+  logger_levels:
+    reader.vm: debug  # affects only VmReader logs
+    model: warning  # applies to all components with 'model' prefix, such as 'model.zscore_online', 'model.prophet', etc.
+    # once commented out in hot-reload mode, will use the default logger level set by --loggerLevel command line argument
+    # monitoring.push: critical

+To disable heatmap view press on settings icon in the top-right corner of graph area and disable `Histogram mode` toggle. 
 
-Graphs in `vmui` support scrolling and zooming:
+**Time range**
 
-* Select the needed time range on the graph in order to zoom in into the selected time range. Hold `ctrl` (or `cmd` on MacOS) and scroll down in order to zoom out.
-* Hold `ctrl` (or `cmd` on MacOS) and scroll up in order to zoom in the area under cursor.
-* Hold `ctrl` (or `cmd` on MacOS) and drag the graph to the left / right in order to move the displayed time range into the future / past.
+The time range for graphs can be adjusted in multiple ways:
 
-Query history can be navigated by holding `Ctrl` (or `Cmd` on MacOS) and pressing `up` or `down` arrows on the keyboard while the cursor is located in the query input field.
+* Click on time picker in the top-right corner to select a relative (`Last N minutes`) or absolute time range (specify `From` and `To`);
+* Zoom-in into graph by click-and-drag motion over the graph area;
+* When hovering cursor over the graph area, hold `ctrl` (or `cmd` on MacOS) and scroll up or down to zoom out or zoom in;
+* When hovering cursor over the graph area, hold `ctrl` (or `cmd` on MacOS) and drag the graph to the left / right to move the displayed time range into the future / past.
 
-Multi-line queries can be entered by pressing `Shift-Enter` in query input field.
+**Legend**
+
+Legend is displayed below the graph area. 
+Clicking on item in legend hides all other items from displaying. Clicking on the item while holding the `ctrl` key hides 
+only this item.
+
+Clicking on the label-value pair in item automatically copies it into buffer, so it can be pasted later.
+
+There are additional visualization settings in the top right-corner of the legend view: switching to table view,
+hiding common labels, etc.
+
+**Troubleshooting**
 
 When querying the [backfilled data](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#backfilling)
 or during [query troubleshooting](https://docs.victoriametrics.com/victoriametrics/troubleshooting/#unexpected-query-results),
 it may be useful disabling response cache by clicking `Disable cache` checkbox.
 
-VMUI automatically adjusts the interval between datapoints on the graph depending on the horizontal resolution and on the selected time range.
-The step value can be customized by changing `Step value` input.
+Query can be [traced](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#query-tracing) 
+by clicking on `Trace query` toggle below query input area and executing query again. Once trace is generated, click
+on it to expand for more details.
 
-VMUI allows investigating correlations between multiple queries on the same graph. Just click `Add Query` button,
-enter an additional query in the newly appeared input field and press `Enter`.
-Results for all the queries are displayed simultaneously on the same graph.
-Graphs for a particular query can be temporarily hidden by clicking the `eye` icon on the right side of the input field.
-When the `eye` icon is clicked while holding the `ctrl` key, then query results for the rest of queries become hidden
-except of the current query results.
+The query and its trace can be exported by clicking on `debug` icon in top right corner of trace block. The exported file 
+file can be loaded again in VMUI on `Tools=>Query Analyzer` page.
 
-VMUI allows sharing query and [trace](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#query-tracing) results by clicking on
-`Export query` button in top right corner of the graph area. The query and trace will be exported as a file that later
-can be loaded in VMUI via `Query Analyzer` tool.
-
-See the [example VMUI at VictoriaMetrics playground](https://play.victoriametrics.com/select/accounting/1/6a716b0f-38bc-4856-90ce-448fd713e3fe/prometheus/graph/?g0.expr=100%20*%20sum(rate(process_cpu_seconds_total))%20by%20(job)&g0.range_input=1d).
+`Raw query` page allows displaying raw, unmodified data. It can be useful for seeing the actual scrape interval or detecting
+sample duplicates.
