+## Configure Pushgw.Writers
+
+Configure Pushgw.Writers in [config.toml](https://github.com/ccfos/nightingale/blob/main/etc/config.toml#L150). The default configuration is as follows:
+
+```toml
+[[Pushgw.Writers]] 
+# Url = "http://127.0.0.1:8480/insert/0/prometheus/api/v1/write"
+Url = "http://127.0.0.1:9090/api/v1/write"
+...
+```
+
+Make sure that the Url is `prometheus remote write` api address.
+
+
+## Install agent
+
+We recommand you to use [Categraf](/docs/agent/categraf/) as agent collector. Categraf can receive monitoring data as well as heartbeat requests.
+
+Then start Categraf and you're done.
+
+## Check Host List
+
+Menu location: `Infrastructure` -> `Host`. You'll see the host list under `All hosts`.

+
+## Check Host Metrics
+
+Menu location: `Metrics` -> `Explorer`. You can use `cpu_usage_active` as promql query to check host metrics.
+
+## Import dashboards
+
+Menu location: `Dashboard` -> `Built-in`. You can clone `Linux Host by Categraf` under Linux Category to `Default busi group` then view the data through the dashboard.
+
+## Import alerting rules
+
+Menu location: `Monitors` -> `Built-in`. You can clone all the rules under Linux Category to `Default busi group` then alarm will be triggered if any rule is violated.
