-VictoriaMetrics supports `__graphite__` pseudo-label for selecting time series with Graphite-compatible filters in [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html). For example, `{__graphite__="foo.*.bar"}` is equivalent to `{__name__=~"foo[.][^.]*[.]bar"}`, but it works faster and it is easier to use when migrating from Graphite to VictoriaMetrics. See [docs for Graphite paths and wildcards](https://graphite.readthedocs.io/en/latest/render_api.html#paths-and-wildcards).

VictoriaMetrics also supports [label_graphite_group](https://docs.victoriametrics.com/metricsql/#label_graphite_group) function for extracting the given groups from Graphite metric name.
 
 The `__graphite__` pseudo-label supports e.g. alternate regexp filters such as `(value1|...|valueN)`. They are transparently converted to `{value1,...,valueN}` syntax [used in Graphite](https://graphite.readthedocs.io/en/latest/render_api.html#paths-and-wildcards). This allows using [multi-value template variables in Grafana](https://grafana.com/docs/grafana/latest/variables/formatting-multi-value-variables/) inside `__graphite__` pseudo-label. For example, Grafana expands `{__graphite__=~"foo.($bar).baz"}` into `{__graphite__=~"foo.(x|y).baz"}` if `$bar` template variable contains `x` and `y` values. In this case the query is automatically converted into `{__graphite__=~"foo.{x,y}.baz"}` before execution.

 **This release contains [the issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5959), which can prevent from storing data for new time series under high rate of search queries. Please rollback to [v1.98.0](https://docs.victoriametrics.com/changelog/#v1980) or upgrade to [v1.100.1](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.100.1).**
 
-* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): propagate [label filters](https://docs.victoriametrics.com/keyconcepts/#filtering) via all the [label manipulation functions](https://docs.victoriametrics.com/metricsql/#label-manipulation-functions).

These metrics may help debugging query performance slowdown related to the increased number of parts in the last partition, since usually all the ingested data is written to the last partition and all the queries are performed over the recently ingested data, e.g. the last partition.
 * FEATURE: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): expose `vm_snapshots` [metric](https://docs.victoriametrics.com/#monitoring), which shows the current number of snapshots created via [snapshot API](https://docs.victoriametrics.com/#how-to-work-with-snapshots).

 * FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent/): add `-remoteWrite.tlsHandshakeTimeout` command-line flag for tuning the timeout needed for establishing TLS connections to `-remoteWrite.url`. Bigger tls handshake timeouts should reduce the probability of `http: TLS handshake error from ...: EOF` errors at the remote storage side under high load.

This should reduce the size of `MetricName -> internal_series_id` cache (aka `vm_cache_size_bytes{type="storage/tsid"}`) when ingesting samples for the same time series with distinct order of labels. For example, `foo{k1="v1",k2="v2"}` and `foo{k2="v2",k1="v1"}` represent a single time series.

 * FEATURE: return shorter error messages to Grafana and to other clients requesting [/api/v1/query](https://docs.victoriametrics.com/keyConcepts.html#instant-query) and [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query) endpoints. This should simplify reading these errors by humans. The long error message with full context is still written to logs.
-* FEATURE: add the ability to fine-tune the number of points, which can be generated per each matching time series during [subquery](https://docs.victoriametrics.com/MetricsQL.html#subqueries) evaluation. This can be done with the `-search.maxPointsSubqueryPerTimeseries` command-line flag. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2922).

 ## 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.

 ## Resource consumption of vmanomaly
 `vmanomaly` itself is a lightweight service, resource usage is primarily dependent on [scheduling](/anomaly-detection/components/scheduler.html) (how often and on what data to fit/infer your models), [# and size of timeseries returned by your queries](/anomaly-detection/components/reader.html#vm-reader), and the complexity of the employed [models](anomaly-detection/components/models.html). Its resource usage is directly related to these factors, making it adaptable to various operational scales.
 
 ## Scaling vmanomaly
-`vmanomaly` can be scaled horizontally by launching multiple independent instances, each with its own [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html) queries and [configurations](/anomaly-detection/components/). This flexibility allows it to handle varying data volumes and throughput demands efficiently.

 In this context, the metric `node_cpu_seconds_total` provides a comprehensive breakdown of the time each CPU core has spent in various operational modes. These modes include: _user_, _system_, _iowait_, _idle_, _irq&softirq_, _guest_, and _steal_. Each of these eight modes is mutually exclusive, offering distinct insights into CPU activity. For instance, a predominant _iowait_ suggests disk or network bottlenecks, while elevated levels in _user_ or _system_ indicate significant CPU utilization.
