+Here it describes how to configure custom parameters for alerts, etc.
+
+**Configuration file `application.yml` of `hertzbeat`**
+
+Configuring the HertzBeat configuration file:
+
+- Modify the configuration file located at `hertzbeat/config/application.yml`
+- **Docker Deployment:** ⚠️ When using a Docker container, the `application.yml` file must be mounted to the host machine
+- **Installation Package Deployment:** Extract the package and modify the configuration file located at `hertzbeat/config/application.yml`
+
+## 0. Virtual Thread Configuration
+
+Virtual-thread related defaults, tuning guidance, rollback switches, and Docker/package config locations are documented on a dedicated page:
+
+- [Virtual Thread Configuration](./virtual-thread)
+
+## 1. Configuring Custom Alert Parameters
+
+```yaml
+alerter:
+  # Custom console URL
+  console-url: https://console.tancloud.io
+```
+
+## 2. Using an External Redis Instead of In-Memory Storage for Real-Time Metric Data
+
+> By default, real-time metric data is stored in memory. You can configure Redis as a replacement using the settings below.
+
+⚠️ Note: Set `memory.enabled: false, redis.enabled: true`
+
+```yaml
+warehouse:
+  store:
+    memory:
+      enabled: false
+      init-size: 1024
+    redis:
+      enabled: true
+      host: 127.0.0.1
+      port: 6379
+      password: 123456
+```
