# Quick start
|
||
|
||
## How to install
|
||
|
||
VictoriaMetrics is distributed in two forms:
|
||
* [Single-server-VictoriaMetrics](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html) - all-in-one
|
||
binary, which is very easy to use and maintain.
|
||
Single-server-VictoriaMetrics perfectly scales vertically and easily handles millions of metrics/s;
|
||
* [VictoriaMetrics Cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html) - set of components
|
||
for building horizontally scalable clusters.
|
||
|
||
Single-server-VictoriaMetrics VictoriaMetrics is available as:
|
||
|
||
* [Managed VictoriaMetrics at AWS](https://aws.amazon.com/marketplace/pp/prodview-4tbfq5icmbmyc)
|
||
* [Docker images](https://hub.docker.com/r/victoriametrics/victoria-metrics/)
|
||
* [Snap packages](https://snapcraft.io/victoriametrics)
|
||
* [Helm Charts](https://github.com/VictoriaMetrics/helm-charts#list-of-charts)
|
||
* [Binary releases](https://github.com/VictoriaMetrics/VictoriaMetrics/releases)
|
||
* [Source code](https://github.com/VictoriaMetrics/VictoriaMetrics).
|
||
See [How to build from sources](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#how-to-build-from-sources)
|
||
* [VictoriaMetrics on Linode](https://www.linode.com/marketplace/apps/victoriametrics/victoriametrics/)
|
||
* [VictoriaMetrics on DigitalOcean](https://marketplace.digitalocean.com/apps/victoriametrics-single)
|
||
|
||
Just download VictoriaMetrics and follow
|
||
[these instructions](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#how-to-start-victoriametrics).
|
||
Then read [Prometheus setup](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#prometheus-setup)
|
||
and [Grafana setup](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#grafana-setup) docs.
|
||
|
||
VictoriaMetrics is developed at a fast pace, so it is recommended periodically checking the [CHANGELOG](https://docs.victoriametrics.com/CHANGELOG.html) and performing [regular upgrades](https://docs.victoriametrics.com/#how-to-upgrade-victoriametrics).
|
||
|
||
|
||
### Starting VM-Single via Docker
|
||
|
||
The following commands download the latest available
|
||
[Docker image of VictoriaMetrics](https://hub.docker.com/r/victoriametrics/victoria-metrics)
|
||
and start it at port 8428, while storing the ingested data at `victoria-metrics-data` subdirectory
|
||
under the current directory:
|
||
|
||
<div class="with-copy" markdown="1">
|
||
|
||
```console
|
||
docker pull victoriametrics/victoria-metrics:latest
|
||
docker run -it --rm -v `pwd`/victoria-metrics-data:/victoria-metrics-data -p 8428:8428 victoriametrics/victoria-metrics:latest
|
||
```
|
||
|
||
</div>
|
||
|
||
Open <a href="http://localhost:8428">http://localhost:8428</a> in web browser
|
||
and read [these docs](https://docs.victoriametrics.com/#operation).
|
||
|
||
There is also [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html)
|
||
- horizontally scalable installation, which scales to multiple nodes.
|
||
|
||
### Starting VM-Cluster via Docker
|
||
|
||
The following commands clone the latest available
|
||
[VictoriaMetrics repository](https://github.com/VictoriaMetrics/VictoriaMetrics)
|
||
and start the docker container via 'make docker-cluster-up'. Further customization is possible by editing
|
||
the [docker-compose-cluster.yml](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/deployment/docker/docker-compose-cluster.yml)
|
||
file.
|
||
|
||
<div class="with-copy" markdown="1">
|
||
|
||
```console
|
||
git clone https://github.com/VictoriaMetrics/VictoriaMetrics &&
|
||
make docker-cluster-up
|
||
```
|
||
|
||
</div>
|
||
|
||
See more details [here](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/deployment/docker#readme).
|
||
|
||
* [Cluster setup](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#cluster-setup)
|
||
|
||
## Write data
|
||
|
||
There are two main models in monitoring for data collection:
|
||
[push](https://docs.victoriametrics.com/keyConcepts.html#push-model)
|
||
and [pull](https://docs.victoriametrics.com/keyConcepts.html#pull-model).
|
||
Both are used in modern monitoring and both are supported by VictoriaMetrics.
|
||
|
||
See more details on [writing data here](https://docs.victoriametrics.com/keyConcepts.html#write-data).
|
||
|
||
|
||
## Query data
|
||
|
||
VictoriaMetrics provides an
|
||
[HTTP API](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#prometheus-querying-api-usage)
|
||
for serving read queries. The API is used in various integrations such as
|
||
[Grafana](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#grafana-setup).
|
||
The same API is also used by
|
||
[VMUI](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#vmui) - graphical User Interface
|
||
for querying and visualizing metrics.
|
||
|
||
[MetricsQL](https://docs.victoriametrics.com/MetricsQL.html) - is he query language for executing read queries
|
||
in VictoriaMetrics. MetricsQL is a [PromQL](https://prometheus.io/docs/prometheus/latest/querying/basics)
|
||
-like query language with a powerful set of functions and features for working specifically with time series data.
|
||
|
||
See more details on [querying data here](https://docs.victoriametrics.com/keyConcepts.html#query-data)
|
||
|
||
|
||
## Alerting
|
||
|
||
It is not possible to physically trace all changes on graphs all the time, that is why alerting exists.
|
||
In [vmalert](https://docs.victoriametrics.com/vmalert.html) it is possible to create a set of conditions
|
||
based on PromQL and MetricsQL queries that will send a notification when such conditions are met.
|
||
|
||
## Data migration
|
||
|
||
Migrating data from other TSDBs to VictoriaMetrics is as simple as importing data via any of
|
||
[supported formats](https://docs.victoriametrics.com/keyConcepts.html#push-model).
|
||
|
||
The migration might get easier when using [vmctl](https://docs.victoriametrics.com/vmctl.html) - VictoriaMetrics
|
||
command line tool. It supports the following databases for migration to VictoriaMetrics:
|
||
* [Prometheus using snapshot API](https://docs.victoriametrics.com/vmctl.html#migrating-data-from-prometheus);
|
||
* [Thanos](https://docs.victoriametrics.com/vmctl.html#migrating-data-from-thanos);
|
||
* [InfluxDB](https://docs.victoriametrics.com/vmctl.html#migrating-data-from-influxdb-1x);
|
||
* [OpenTSDB](https://docs.victoriametrics.com/vmctl.html#migrating-data-from-opentsdb);
|
||
* [Migrate data between VictoriaMetrics single and cluster versions](https://docs.victoriametrics.com/vmctl.html#migrating-data-from-victoriametrics).
|
||
|
||
## Productionisation
|
||
|
||
When going to production with VictoriaMetrics we recommend following the recommendations.
|
||
|
||
### Monitoring
|
||
|
||
Each VictoriaMetrics component emits its own metrics with various details regarding performance
|
||
and health state. Docs for the components also contain a `Monitoring` section with an explanation
|
||
of what and how should be monitored. For example,
|
||
[Single-server-VictoriaMetrics Monitoring](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#monitoring).
|
||
|
||
VictoriaMetric team prepared a list of [Grafana dashboards](https://grafana.com/orgs/victoriametrics/dashboards)
|
||
for the main components. Each dashboard contains a lot of useful information and tips. It is recommended
|
||
to have these dashboards installed and up to date.
|
||
|
||
The list of alerts for [single](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/deployment/docker/alerts.yml)
|
||
and [cluster](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/cluster/deployment/docker/alerts.yml)
|
||
versions would also help to identify and notify about issues with the system.
|
||
|
||
The rule of thumb is to have a separate installation of VictoriaMetrics or any other monitoring system
|
||
to monitor the production installation of VictoriaMetrics. This would make monitoring independent and
|
||
will help identify problems with the main monitoring installation.
|
||
|
||
See more details in the article [VictoriaMetrics Monitoring](https://victoriametrics.com/blog/victoriametrics-monitoring/).
|
||
|
||
### Capacity planning
|
||
|
||
See capacity planning sections in [docs](https://docs.victoriametrics.com) for
|
||
[Single-server-VictoriaMetrics](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#capacity-planning).
|
||
and [VictoriaMetrics Cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#capacity-planning).
|
||
|
||
Capacity planning isn't possible without [monitoring](#monitoring), so consider configuring it first.
|
||
Understanding resource usage and performance of VictoriaMetrics also requires knowing the tech terms
|
||
[active series](https://docs.victoriametrics.com/FAQ.html#what-is-an-active-time-series),
|
||
[churn rate](https://docs.victoriametrics.com/FAQ.html#what-is-high-churn-rate),
|
||
[cardinality](https://docs.victoriametrics.com/FAQ.html#what-is-high-cardinality),
|
||
[slow inserts](https://docs.victoriametrics.com/FAQ.html#what-is-a-slow-insert).
|
||
All of them are present in [Grafana dashboards](https://grafana.com/orgs/victoriametrics/dashboards).
|
||
|
||
|
||
### Data safety
|
||
|
||
It is recommended to read [Replication and data safety](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#replication-and-data-safety),
|
||
[Why replication doesn’t save from disaster?](https://valyala.medium.com/speeding-up-backups-for-big-time-series-databases-533c1a927883)
|
||
and [backups](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#backups).
|
||
|
||
|
||
### Configuring limits
|
||
|
||
To avoid excessive resource usage or performance degradation limits must be in place:
|
||
* [Resource usage limits](https://docs.victoriametrics.com/FAQ.html#how-to-set-a-memory-limit-for-victoriametrics-components);
|
||
* [Cardinality limiter](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#cardinality-limiter).
|
||
|
||
### Security recommendations
