 TDinsight is a solution for monitoring TDengine using the builtin native monitoring database and [Grafana].
 
-After TDengine starts, it will automatically create a monitoring database `log`. TDengine will automatically write many metrics in specific intervals into the `log` database. The metrics may include the server's CPU, memory, hard disk space, network bandwidth, number of requests, disk read/write speed, slow queries, other information like important system operations (user login, database creation, database deletion, etc.), and error alarms. With [Grafana] and [TDengine Data Source Plugin](https://github.com/taosdata/grafanaplugin/releases), TDinsight can visualize cluster status, node information, insertion and query requests, resource usage, vnode, dnode, and mnode status, exception alerts and many other metrics. This is very convenient for developers who want to monitor TDengine cluster status in real-time. This article will guide users to install the Grafana server, automatically install the TDengine data source plug-in, and deploy the TDinsight visualization panel using the `TDinsight.sh` installation script.

 **管理节点（mnode）：** 一个虚拟的逻辑单元，负责所有数据节点运行状态的监控和维护，以及节点之间的负载均衡（图中 M）。同时，管理节点也负责元数据（包括用户、数据库、超级表等）的存储和管理，因此也称为 Meta Node。TDengine 集群中可配置多个（最多不超过 3 个）mnode，它们自动构建成为一个虚拟管理节点组（图中 M1，M2，M3）。mnode 支持多副本，采用 RAFT 一致性协议，保证系统的高可用与高可靠，任何数据更新操作只能在 Leader 上进行。mnode 集群的第一个节点在集群部署时自动完成，其他节点的创建与删除由用户通过 SQL 命令完成。每个 dnode 上至多有一个 mnode，由所属的数据节点的 EP 来唯一标识。每个 dnode 通过内部消息交互自动获取整个集群中所有 mnode 所在的 dnode 的 EP。
 
-**弹性计算节点（qnode）：** 一个虚拟的逻辑单元，运行查询计算任务，也包括基于系统表来实现的 show 命令（图中 Q）。集群中可配置多个 qnode，在整个集群内部共享使用（图中 Q1，Q2，Q3）。qnode 不与具体的 DB 绑定，即一个 qnode 可以同时执行多个 DB 的查询任务。每个 dnode 上至多有一个 qnode，由所属的数据节点的 EP 来唯一标识。客户端通过与 mnode 交互，获取可用的 qnode 列表，当没有可用的 qnode 时，计算任务在 vnode 中执行。

 **流计算节点（snode）：** 一个虚拟的逻辑单元，只运行流计算任务（图中 S）。集群中可配置多个 snode，在整个集群内部共享使用（图中 S1，S2，S3）。snode 不与具体的 stream 绑定，即一个 snode 可以同时执行多个 stream 的计算任务。每个 dnode 上至多有一个 snode，由所属的数据节点的 EP 来唯一标识。由 mnode 调度可用的 snode 完成流计算任务，当没有可用的 snode 时，流计算任务在 vnode 中执行。
