## Deduplication
VictoriaMetrics de-duplicates data points if `-dedup.minScrapeInterval` command-line flag
is set to positive duration. For example, `-dedup.minScrapeInterval=60s` would de-duplicate data points
on the same time series if they fall within the same discrete 60s bucket. The earliest data point will be kept. In the case of equal timestamps, an arbitrary data point will be kept. The `-dedup.minScrapeInterval=D` is equivalent to `-downsampling.period=0s:D` if [downsampling](#downsampling) is enabled.

In the case of equal timestamps, an arbitrary data point will be kept. See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2112#issuecomment-1032587618) for more details on how downsampling works.
The `-dedup.minScrapeInterval=D` is equivalent to `-downsampling.period=0s:D` if [downsampling](#downsampling) is enabled. It is safe to use deduplication and downsampling simultaneously.
The recommended value for `-dedup.minScrapeInterval` must equal to `scrape_interval` config from Prometheus configs. It is recommended to have a single `scrape_interval` across all the scrape targets. See [this article](https://www.robustperception.io/keep-it-simple-scrape_interval-id) for details.

`external_labels` section in their configs, so they write data to the same time series.
## Storage
VictoriaMetrics stores time series data in [MergeTree](https://en.wikipedia.org/wiki/Log-structured_merge-tree)-like
data structures. On insert, VictoriaMetrics accumulates up to 1s of data and dumps it on disk to
`<-storageDataPath>/data/small/YYYY_MM/` subdirectory forming a `part` with the following
name pattern `rowsCount_blocksCount_minTimestamp_maxTimestamp`. Each part consists of two "columns":
values and timestamps. These are sorted and compressed raw time series values. Additionally, part contains
index files for searching for specific series in the values and timestamps files.
`Parts` are periodically merged into the bigger parts. The resulting `part` is constructed
under `<-storageDataPath>/data/{small,big}/YYYY_MM/tmp` subdirectory. When the resulting `part` is complete, it is atomically moved from the `tmp`
to its own subdirectory, while the source parts are atomically removed. The end result is that the source
parts are substituted by a single resulting bigger `part` in the `<-storageDataPath>/data/{small,big}/YYYY_MM/` directory.
Information about merging process is available in [single-node VictoriaMetrics](https://grafana.com/dashboards/10229)
and [clustered VictoriaMetrics](https://grafana.com/grafana/dashboards/11176) Grafana dashboards.
See more details in [monitoring docs](#monitoring).
The `merge` process is usually named "compaction", because the resulting `part` size is usually smaller than
the sum of the source `parts`. There are following benefits of doing the merge process:
* it improves query performance, since lower number of `parts` are inspected with each query;
* it reduces the number of data files, since each `part`contains fixed number of files;
* better compression rate for the resulting part.
Newly added `parts` either appear in the storage or fail to appear.
Storage never contains partially created parts. The same applies to merge process — `parts` are either fully
merged into a new `part` or fail to merge. There are no partially merged `parts` in MergeTree.
`Part` contents in MergeTree never change. Parts are immutable. They may be only deleted after the merge
to a bigger `part` or when the `part` contents goes outside the configured `-retentionPeriod`.
See [this article](https://valyala.medium.com/how-victoriametrics-makes-instant-snapshots-for-multi-terabyte-time-series-data-e1f3fb0e0282) for more details.
See also [how to work with snapshots](#how-to-work-with-snapshots).
## Retention
Retention is configured with `-retentionPeriod` command-line flag. For instance, `-retentionPeriod=3` means
that the data will be stored for 3 months and then deleted.
Data is split in per-month partitions inside `<-storageDataPath>/data/small` and `<-storageDataPath>/data/big` folders.
Data is split in per-month partitions inside `<-storageDataPath>/data/{small,big}` folders.
Data partitions outside the configured retention are deleted on the first day of new month.
Each partition consists of one or more data parts with the following name pattern `rowsCount_blocksCount_minTimestamp_maxTimestamp`.
Data parts outside of the configured retention are eventually deleted during [background merge](https://medium.com/@valyala/how-victoriametrics-makes-instant-snapshots-for-multi-terabyte-time-series-data-e1f3fb0e0282).
Data parts outside of the configured retention are eventually deleted during
[background merge](https://medium.com/@valyala/how-victoriametrics-makes-instant-snapshots-for-multi-terabyte-time-series-data-e1f3fb0e0282).
In order to keep data according to `-retentionPeriod` max disk space usage is going to be `-retentionPeriod` + 1 month.
For example if `-retentionPeriod` is set to 1, data for January is deleted on March 1st.

`vmagent` doesn't support the following sections in Prometheus config file passed to `-promscrape.config` command-line flag:
* [remote_write](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#remote_write). This section is substituted with various `-remoteWrite*` command-line flags. See [the full list of flags](#advanced-usage).

# CHANGELOG
The following tip changes can be tested by building VictoriaMetrics components from the latest commits according to the following docs:
* [How to build single-node VictoriaMetrics](https://docs.victoriametrics.com/#how-to-build-from-sources)
* [How to build cluster version of VictoriaMetrics](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#building-from-sources)
* [How to build vmagent](https://docs.victoriametrics.com/vmagent.html#how-to-build-from-sources)

* [How to build vmctl](https://docs.victoriametrics.com/vmctl.html#how-to-build)
## tip
* FEATURE: publish VictoriaMetrics binaries for MacOS amd64 and MacOS arm64 (aka MacBook M1) at [releases page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1896) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1851).
* FEATURE: reduce CPU and disk IO usage during `indexdb` rotation once per `-retentionPeriod`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401).
* FEATURE: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): add `-dropSamplesOnOverload` command-line flag for `vminsert`. If this flag is set, then `vminsert` drops incoming data if the destination `vmstorage` is temporarily unavailable or cannot keep up with the ingestion rate. The number of dropped rows can be [monitored](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#monitoring) via `vm_rpc_rows_dropped_on_overload_total` metric at `vminsert`.
* FEATURE: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): improve re-routing logic, so it re-routes incoming data more evenly if some of `vmstorage` nodes are temporarily unavailable and/or accept data at slower rate than other `vmstorage` nodes. Also significantly reduce possible re-routing storm when `vminsert` runs with `-disableRerouting=false` command-line flag. This should help the following issues: [one](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1337), [two](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1165), [three](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1054), [four](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/791), [five](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1544).
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): cover more cases with the [label filters' propagation optimization](https://utcc.utoronto.ca/~cks/space/blog/sysadmin/PrometheusLabelNonOptimization). This should improve the average performance for practical queries. The following cases are additionally covered:
@ -14,19 +24,30 @@ sort: 15
* Multi-level binary operations. For example, `foo{a="b"} + bar{x="y"} + baz{z="q"}` is now optimized to `foo{a="b",x="y",z="q"} + bar{a="b",x="y",z="q"} + baz{a="b",x="y",z="q"}`
* Aggregate functions. For example, `sum(foo{a="b"}) by (c) + bar{c="d"}` is now optimized to `sum(foo{a="b",c="d"}) by (c) + bar{c="d"}`
* FEATURE [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): optimize joining with `*_info` labels. For example: `kube_pod_created{namespace="prod"} * on (uid) group_left(node) kube_pod_info` now automatically adds the needed filters on `uid` label to `kube_pod_info` before selecting series for the right side of `*` operation. This may save CPU, RAM and disk IO resources. See [this article](https://www.robustperception.io/exposing-the-software-version-to-prometheus) for details on `*_info` labels. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1827).
* FEATURE: all: improve performance for arm64 builds of VictoriaMetrics components by up to 15%. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2102).
* FEATURE: all: expose `process_cpu_cores_available` metric, which shows the number of CPU cores available to the app. The number can be fractional if the corresponding cgroup limit is set to a fractional value. This metric is useful for alerting on CPU saturation. For example, the following query alerts when the app uses more than 90% of CPU during the last 5 minutes: `rate(process_cpu_seconds_total[5m]) / process_cpu_cores_available > 0.9` . See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2107).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add ability to configure notifiers (e.g. alertmanager) via a file in the way similar to Prometheus. See [these docs](https://docs.victoriametrics.com/vmalert.html#notifier-configuration-file), [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2127).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add support for Consul service discovery for notifiers. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1947).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add support for specifying Basic Auth password for notifiers via a file. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1567).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): provide the ability to fetch target responses on behalf of `vmagent` by clicking the `response` link for the needed target at `/targets` page. This feature may be useful for debugging responses from targets located in isolated environments.
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): show the total number of scrapes and the total number of scrape errors per target at `/targets` page. This information may be useful when debugging unreliable scrape targets.
* FEATURE: vmagent and single-node VictoriaMetrics: disallow unknown fields at `-promscrape.config` file. Previously unknown fields were allowed. This could lead to long-living silent config errors. The previous behaviour can be returned by passing `-promscrape.config.strictParse=false` command-line flag.
* FEATURE: vmagent: add `__meta_kubernetes_endpointslice_label*` and `__meta_kubernetes_endpointslice_annotation*` labels for `role: endpointslice` targets in [kubernetes_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#kubernetes_sd_config) to be consistent with other `role` values. See [this issue](https://github.com/prometheus/prometheus/issues/10284).
* FEATURE: vmagent: add `collapse all` and `expand all` buttons to `http://vmagent:8429/targets` page. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2021).
* FEATURE: vmagent: support Prometheus-like durations in `-promscrape.config`. See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/817#issuecomment-1033384766).
* FEATURE: automatically re-read `-tlsCertFile` and `-tlsKeyFile` files, so their contents can be updated without the need to restart VictoriaMetrics apps. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2171).
* BUGFIX: calculate [absent_over_time()](https://docs.victoriametrics.com/MetricsQL.html#absent_over_time) in the same way as Prometheus does. Previously it could return multiple time series instead of at most one time series like Prometheus does. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2130).
* BUGFIX: return proper results from `highestMax()` function at [Graphite render API](https://docs.victoriametrics.com/#graphite-render-api-usage). Previously it was incorrectly returning timeseries with min peaks instead of max peaks.
* BUGFIX: properly limit indexdb cache sizes. Previously they could exceed values set via `-memory.allowedPercent` and/or `-memory.allowedBytes` when `indexdb` contained many data parts. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix a bug, which could break time range picker when editing `From` or `To` input fields. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2080).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix a bug, which could break switching between `graph`, `json` and `table` views. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2084).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix possible UI freeze after querying `node_uname_info` time series. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2115).
* BUGFIX: show the original location of the warning or error message when logging throttled messages. Previously the location inside `lib/logger/throttler.go` was shown. This could increase the complexity of debugging.
* BUGFIX: vmalert: fix links at web UI. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2167).
* BUGFIX: vmagent: properly discover pods without exposed ports for the given service for `role: endpoints` and `role: endpointslice` in [kubernetes_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#kubernetes_sd_config). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2134).
* BUGFIX: vmagent: properly display `zone` contents for `gce_sd_configs` section at `http://vmagent:8429/config` page. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2179). Thanks to @artifactori for the bugfix.
* BUGFIX: vmagent: properly handle `all_tenants: true` config option at `openstack_sd_config`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2182).

is set to positive duration. For example, `-dedup.minScrapeInterval=60s` would de-duplicate data points

## Storage
VictoriaMetrics stores time series data in [MergeTree](https://en.wikipedia.org/wiki/Log-structured_merge-tree)-like
data structures. On insert, VictoriaMetrics accumulates up to 1s of data and dumps it on disk to
`<-storageDataPath>/data/small/YYYY_MM/` subdirectory forming a `part` with the following
name pattern `rowsCount_blocksCount_minTimestamp_maxTimestamp`. Each part consists of two "columns":
values and timestamps. These are sorted and compressed raw time series values. Additionally, part contains
index files for searching for specific series in the values and timestamps files.
`Parts` are periodically merged into the bigger parts. The resulting `part` is constructed
under `<-storageDataPath>/data/{small,big}/YYYY_MM/tmp` subdirectory. When the resulting `part` is complete, it is atomically moved from the `tmp`
to its own subdirectory, while the source parts are atomically removed. The end result is that the source
parts are substituted by a single resulting bigger `part` in the `<-storageDataPath>/data/{small,big}/YYYY_MM/` directory.
Information about merging process is available in [single-node VictoriaMetrics](https://grafana.com/dashboards/10229)
and [clustered VictoriaMetrics](https://grafana.com/grafana/dashboards/11176) Grafana dashboards.
See more details in [monitoring docs](#monitoring).
The `merge` process is usually named "compaction", because the resulting `part` size is usually smaller than
the sum of the source `parts`. There are following benefits of doing the merge process:
* it improves query performance, since lower number of `parts` are inspected with each query;
* it reduces the number of data files, since each `part`contains fixed number of files;
* better compression rate for the resulting part.
Newly added `parts` either appear in the storage or fail to appear.
Storage never contains partially created parts. The same applies to merge process — `parts` are either fully
merged into a new `part` or fail to merge. There are no partially merged `parts` in MergeTree.
`Part` contents in MergeTree never change. Parts are immutable. They may be only deleted after the merge
to a bigger `part` or when the `part` contents goes outside the configured `-retentionPeriod`.
See [this article](https://valyala.medium.com/how-victoriametrics-makes-instant-snapshots-for-multi-terabyte-time-series-data-e1f3fb0e0282) for more details.
See also [how to work with snapshots](#how-to-work-with-snapshots).
## Retention
Retention is configured with `-retentionPeriod` command-line flag. For instance, `-retentionPeriod=3` means
that the data will be stored for 3 months and then deleted.
Data is split in per-month partitions inside `<-storageDataPath>/data/small` and `<-storageDataPath>/data/big` folders.
Data is split in per-month partitions inside `<-storageDataPath>/data/{small,big}` folders.
Data partitions outside the configured retention are deleted on the first day of new month.
Each partition consists of one or more data parts with the following name pattern `rowsCount_blocksCount_minTimestamp_maxTimestamp`.
Data parts outside of the configured retention are eventually deleted during [background merge](https://medium.com/@valyala/how-victoriametrics-makes-instant-snapshots-for-multi-terabyte-time-series-data-e1f3fb0e0282).
