### Automatic import of preconfigured alert rules
|
||||
|
||||
After summarizing user experience, 14 commonly used alert rules are sorted out. These alert rules can monitor key indicators of the TDengine cluster and report alerts, such as abnormal and exceeded indicators.
|
||||
Starting from TDengine-Server 3.3.4.3 (TDengine-datasource 3.6.3), TDengine Datasource supports automatic import of preconfigured alert rules. You can import 14 alert rules to Grafana (version 11 or later) with one click.
|
||||
In the TDengine-datasource setting interface, turn on the "Load Tengine Alert" switch, click the "Save & test" button, the plugin will automatically load the mentioned 14 alert rules. The rules will be placed in the Grafana alerts directory. If not required, turn off the "Load TDengine Alert" switch, and click the button next to "Clear TDengine Alert" to clear all the alert rules imported into this data source.
|
||||
|
||||
After importing, click on "Alert rules" on the left side of the Grafana interface to view all current alert rules. By configuring contact points, users can receive alert notifications.
|
||||
|
||||
The specific configuration of the 14 alert rules is as follows:
|
||||
|
||||
| alert rule| Rule threshold| Behavior when no data | Data scanning interval |Duration | SQL |
|
||||
| ------ | --------- | ---------------- | ----------- |------- |----------------------|

TDengine users can modify and improve these alert rules according to their own business needs. In Grafana 7.5 and below versions, the Dashboard and Alert rules functions are combined, while in subsequent new versions, the two functions are separated. To be compatible with Grafana7.5 and below versions, an Alert Used Only panel has been added to the TDinsight panel, which is only required for Grafana7.5 and below versions.

The modifiable configuration items in the syntax above are configured in the same way as in the dnode configuration file, the difference being that modifications are dynamic, take immediate effect, and do not require restarting the dnode.
|
||||
For configuration parameters that support dynamic modification, you can use the ALTER DNODE or ALTER ALL DNODES syntax to modify the values of configuration parameters in a dnode. Starting from version 3.3.4.0, the modified configuration parameters will be automatically persisted and will remain effective even after the database service is restarted.
|
||||
|
||||
`value` is the value of the parameter, which needs to be in string format. For example, to change the log output level of dnode 1 to debug:
|
||||
To check whether a configuration parameter supports dynamic modification, please refer to the following page: [taosd Reference](../01-components/01-taosd.md)
|
||||
|
||||
The value is the parameter's value and needs to be in character format. For example, to change the log output level of dnode 1 to debug:
|
||||
|
||||
```sql
|
||||
ALTER DNODE 1 'debugFlag' '143';
|
||||
```
|
||||
### Additional Notes:
|
||||
Configuration parameters in a dnode are divided into global configuration parameters and local configuration parameters. You can check the category field in SHOW VARIABLES or SHOW DNODE dnode_id VARIABLE to determine whether a configuration parameter is a global configuration parameter or a local configuration parameter:
|
||||
|
||||
Local configuration parameters: You can use ALTER DNODE or ALTER ALL DNODES to update the local configuration parameters of a specific dnode or all dnodes.
|
||||
Global configuration parameters: Global configuration parameters require consistency across all dnodes, so you can only use ALTER ALL DNODES to update the global configuration parameters of all dnodes.
|
||||
There are three cases for whether a configuration parameter can be dynamically modified:
|
||||
|
||||
Supports dynamic modification, effective immediately
|
||||
Supports dynamic modification, effective after restart
|
||||
Does not support dynamic modification
|
||||
For configuration parameters that take effect after a restart, you can see the modified values through SHOW VARIABLES or SHOW DNODE dnode_id VARIABLE, but you need to restart the database service to make them effective.

### 31 What should I do if I encounter 'Sync leader is unreachable' when connecting to the cluster for the first time?
|
||||
|
||||
Reporting this error indicates that the first connection to the cluster was successful, but the IP address accessed for the first time was not the leader of mnode. An error occurred when the client attempted to establish a connection with the leader. The client searches for the leader node through EP, which specifies the fqdn and port number. There are two common reasons for this error:
|
||||
|
||||
- The ports of other dnodes in the cluster are not open
|
||||
- The client's hosts file is not configured correctly
|
||||
|
||||
Therefore, first, check whether all ports on the server and cluster (default 6030 for native connections and 6041 for HTTP connections) are open; Next, check if the client's hosts file has configured the fqdn and IP information for all dnodes in the cluster.
|
||||
If the issue still cannot be resolved, it is necessary to contact Taos technical personnel for support.

**补充说明**
|
||||
1. 在 3.2.0.0 ~ 3.3.0.0（不包含）版本生效，启用该参数后不能回退到升级前的版本
|
||||
2. TSZ 压缩算法是通过数据预测技术完成的压缩，所以更适合有规律变化的数据
|
||||
3. TSZ 压缩时间会更长一些，如果您的服务器 CPU 空闲多，存储空间小的情况下适合选用
|
||||
4. 示例：对 float 和 double 类型都启用有损压缩
|
||||
1. 在 3.4.0.0 之后，所有配置参数都将被持久化到本地存储，重启数据库服务后，将默认使用持久化的配置参数列表；如果您希望继续使用 config 文件中配置的参数，需设置 forceReadConfig 为 1。

### 补充说明：
|
||||
配置参数在 dnode 中被分为全局配置参数与局部配置参数，您可以查看 SHOW VARIABLES 或 SHOW DNODE dnode_id VARIABLE 中的 category 字段来确认配置参数属于全局配置参数还是局部配置参数：
|
||||
1. 局部配置参数：您可以使用 ALTER DNODE 或 ALTER ALL DNODES 来更新某一个 dnode 或全部 dnodes 的局部配置参数。
|
||||
2. 全局配置参数：全局配置参数要求各个 dnode 保持一致，所以您只可以使用 ALTER ALL DNODES 来更新全部 dnodes 的全局配置参数。
|
||||
|
||||
配置参数是否可以动态修改，有以下三种情况：
|
||||
1. 支持动态修改 立即生效
|
||||
2. 支持动态修改 重启生效
|
||||
3. 不支持动态修改
|
||||
|

对于重启后生效的配置参数，您可以通过 SHOW VARIABLES 或 SHOW DNODE dnode_id VARIABLE 看到修改后的值，但是需要重启数据库服务才使其生效。

### 31 第一次连接集群时遇到“Sync leader is unreachable”怎么办？
|
||||
报这个错，说明第一次向集群的连接是成功的，但第一次访问的IP不是mnode的leader节点，客户端试图与leader建立连接时发生错误。客户端通过EP，也就是指定的fqdn与端口号寻找leader节点，常见的报错原因有两个：
|
||||
|
||||
- 集群中其他节点的端口没有打开
|
||||
- 客户端的hosts未正确配置
|
||||
|
||||
因此用户首先要检查服务端，集群的所有端口（原生连接默认6030，http连接默认6041）有无打开；其次是客户端的hosts文件中是否配置了集群所有节点的fqdn与IP信息。
|
||||
如仍无法解决，则需要联系涛思技术人员支持。
|
||||
|
||||
### 32 同一台服务器，数据库的数据目录 dataDir 不变，为什么原有数据库丢失且集群 ID 发生了变化？
|
||||
背景知识：TDengine 服务端进程（taosd）在启动时，若数据目录（dataDir，该目录在配置文件 taos.cfg 中指定）下不存在有效的数据文件子目录（如 mnode、dnode 和 vnode 等），则会自动创建这些目录。在创建新的 mnode 目录的同时，会分配一个新的集群 ID，从而产生一个新的集群。
|
||||
|
||||
原因分析：taosd 的数据目录 dataDir 可以指向多个不同的挂载点。如果这些挂载点未在 fstab 文件中配置自动挂载，服务器重启后，dataDir 将仅作为一个本地磁盘的普通目录存在，而未能按预期指向挂载的磁盘。此时，若 taosd 服务启动，它将在 dataDir 下新建目录，从而产生一个新的集群。
|
||||
|
||||
问题影响：服务器重启后，原有数据库丢失（注：并非真正丢失，只是原有的数据磁盘未挂载，暂时看不到）且集群 ID 发生变化，导致无法访问原有数据库。对于企业版用户，如果已针对集群 ID 进行授权，还会发现集群服务器的机器码未变，但原有的授权已失效。如果未针对该问题进行监控或者未及时发现并进行处理，则用户不会注意到原有数据库已经丢失，从而造成损失，增加运维成本。
|
||||
|
||||
问题解决：应在 fstab 文件中配置 dataDir 目录的自动挂载，确保 dataDir 始终指向预期的挂载点和目录，此时，再重启服务器，会找回原有的数据库和集群。在后续的版本中，我们将开发一个功能，使 taosd 在检测到启动前后 dataDir 发生变化时，在启动阶段退出，同时提供相应的错误提示。
