# VictoriaMetrics

VictoriaMetrics is a high-performance, cost-effective monitoring solution and time series database. It is designed to collect, store, and visualize metrics from various sources such as Prometheus exporters, logs, and traces. Here are some key features of VictoriaMetrics:

## 组件

vmagent - lightweight agent for receiving metrics via pull-based and push-based protocols, transforming and sending them to the configured Prometheus-compatible remote storage systems such as VictoriaMetrics.
vmalert - a service for processing Prometheus-compatible alerting and recording rules.
vmalert-tool - a tool for validating alerting and recording rules.
vmauth - authorization proxy and load balancer optimized for VictoriaMetrics products.
vmgateway - authorization proxy with per-tenant rate limiting capabilities.
vmctl - a tool for migrating and copying data between different storage systems for metrics.
vmbackup, vmrestore and vmbackupmanager - tools for creating backups and restoring from backups for VictoriaMetrics data.
vminsert, vmselect and vmstorage - components of VictoriaMetrics cluster.
VictoriaLogs - user-friendly cost-efficient database for logs.

## 结合 prometheus
prometheus 版本 v2.12.0+ 内存增加 ~25%
