VictoriaMetrics - the best long-term remote storage for Prometheus

VictoriaMetrics features

• Native PromQL support. Additionally, VictoriaMetrics extends PromQL with useful features. See Extended PromQL for more details.
• Simple configuration. Just copy-n-paste remote storage URL to Prometheus config and that's it! See Quick Start for more info.
• Reduced operational overhead. Offload operational burden - configuration, capacity planning, scalability, backups, retention, durability - from Prometheus local storage to VictoriaMetrics.
• Insertion rate scales to millions of metric values per second.
• Storage scales to millions of metrics with trillions of metric values.
• Wide range of retention periods - from 1 month to 5 years. Users may create different projects (aka storage namespaces) with different retention periods.
• Fast query engine. It excels on heavy queries over thousands of metrics with millions of metric values.
• The same remote storage URL may be used by multiple Prometheus instances collecting distinct metric sets, so all these metrics may be used in a single query (aka global querying view). This works ideally for multiple Prometheus instances located in different subnetworks / datacenters.
• Accepts data in InfluxDB line protocol, so Telegraf and other influx-compatible agents may send data to VictoriaMetrics.
• Single-server VictoriaMetrics accepts data in Graphite plaintext protocol if -graphiteListenAddr is set and in OpenTSDB format if -opentsdbListenAddr is set.
• VictoriaMetrics supports backfilling, i.e. data points from the past may be inserted into the DB.
• Time series data may be exported via /api/v1/export?match=<metric_selector>. Optional start and end timestamps may be added for exporting time series in the given time range.
• Time series may be deleted via /api/v1/admin/tsdb/delete_series?match[]=<metric_selector>.
• Instant snapshots are supported.
