+> `Grafana` is an open source visualization and analytics platform that helps you easily create, share and monitor dashboards. In this article, we will cover how to use `Grafana` to display historical data in `HertzBeat`.
+
+### Prerequisites
+
+- The `Grafana` service is started and the account password is configured.
+- The `HertzBeat` service is started and the `VictoriaMetrics` timeseries database is configured (note: the `VictoriaMetrics` data source is required).
+
+:::caution Caution.
+`Grafana` can only show historical data for `Prometheus` type of monitoring, currently it does not support monitoring data defined by `yml` in `HertzBeat`.
+:::
+
+### Configuring Grafana in HertzBeat
+
+In the configuration file `hertzbeat.yml` in `HertzBeat`, configure the `Grafana` data source.
+
+```yaml
+grafana:
+  enabled: true
+  url: http://127.0.0.1:3000
+  username: admin
+  password: admin
+```
+
+### Upload Grafana monitor template json file in HertzBeat monitor
+
+In `HertzBeat`, when creating or editing a `Prometheus` type monitor, click Enable Grafana Templates and select the Grafana template json file to upload.
+The monitor template json file can be downloaded at <https://grafana.com/grafana/dashboards/>.
+For example, create a new monitor in `HertzBeat` for `VictoriaMetrics` single node, then open <https://grafana.com/grafana/dashboards/10229-victoriametrics-single-node/>, click `Download JSON` button on the right side. `Download JSON` button on the right to download the template json file. Upload the template json file in the `HertzBeat` monitor, save it.

+> `Grafana`是一个开源的可视化和分析平台，它可以帮助你轻松地创建、分享和监控仪表板。本文将介绍如何在`HertzBeat`中使用`Grafana`展示历史数据。
+
+### 前提条件
+
+- `Grafana`服务已经启动，并配置好了账号密码。
+- `HertzBeat`服务已经启动，并配置好了`VictoriaMetrics`时序数据库(注意: `VictoriaMetrics`数据源是必须的)。
+
+:::caution 注意
+`Grafana`只能展示`Prometheus`类型监控的历史数据,目前并不支持`HertzBeat`中`yml`定义的监控数据。
+:::
+
+### 在HertzBeat中配置Grafana
+
+在`HertzBeat`的配置文件`hertzbeat.yml`中，配置`Grafana`数据源:
+
+```yaml
+grafana:
+  enabled: true
+  url: http://127.0.0.1:3000
+  username: admin
+  password: admin
+```
+
+### 在HertzBeat监控中上传Grafana监控模板json文件
+
+在`HertzBeat`新建或编辑`Prometheus`类型监控时,点击启用Grafana模板,选择Grafana模板json文件上传。
+监控模板json文件可以在 <https://grafana.com/grafana/dashboards/> 下载。
+比如,在`HertzBeat`中新建一个关于`VictoriaMetrics`单节点的监控,然后打开 <https://grafana.com/grafana/dashboards/10229-victoriametrics-single-node/> ,点击右侧 `Download JSON`按钮,下载模板json文件。在`HertzBeat`监控中上传模板json文件,保存。
