### 配置 taosAdapter

配置 taosAdapter 接收 icinga2 数据的方法：

- 在 taosAdapter 配置文件（默认位置 /etc/taos/taosadapter.toml）中使能配置项

```
...
[opentsdb_telnet]
enable = true
maxTCPConnections = 250
tcpKeepAlive = false
dbs = ["opentsdb_telnet", "collectd", "icinga2", "tcollector"]
ports = [6046, 6047, 6048, 6049]
user = "root"
password = "taosdata"
...
```

其中 taosAdapter 默认写入的数据库名称为 `icinga2`，也可以修改 taosAdapter 配置文件 dbs 项来指定不同的名称。user 和 password 填写实际 TDengine 配置的值。修改过 taosAdapter 需重新启动。

- 或使用 taosAdapter 命令行参数的方式，使能 taosAdapter 接收 icinga2 数据功能

```
      --opentsdb_telnet.dbs strings                  opentsdb_telnet db names. Env "TAOS_ADAPTER_OPENTSDB_TELNET_DBS" (default [opentsdb_telnet,collectd_tsdb,icinga2_tsdb,tcollector_tsdb])
      --opentsdb_telnet.enable                       enable opentsdb telnet,warning: without auth info(default false). Env "TAOS_ADAPTER_OPENTSDB_TELNET_ENABLE"
      --opentsdb_telnet.maxTCPConnections int        max tcp connections. Env "TAOS_ADAPTER_OPENTSDB_TELNET_MAX_TCP_CONNECTIONS" (default 250)
      --opentsdb_telnet.password string              opentsdb_telnet password. Env "TAOS_ADAPTER_OPENTSDB_TELNET_PASSWORD" (default "taosdata")
      --opentsdb_telnet.ports ints                   opentsdb telnet tcp port. Env "TAOS_ADAPTER_OPENTSDB_TELNET_PORTS" (default [6046,6047,6048,6049])
      --opentsdb_telnet.tcpKeepAlive                 enable tcp keep alive. Env "TAOS_ADAPTER_OPENTSDB_TELNET_TCP_KEEP_ALIVE"
      --opentsdb_telnet.user string                  opentsdb_telnet user. Env "TAOS_ADAPTER_OPENTSDB_TELNET_USER" (default "root")
```

### 配置 icinga2

- 使能 icinga2 的 opentsdb-writer（参考链接 https://icinga.com/docs/icinga-2/latest/doc/14-features/#opentsdb-writer）
- 修改配置文件 `/etc/icinga2/features-enabled/opentsdb.conf` 填写 <taosAdapter's host\> 为运行 taosAdapter 的服务器的域名或 IP 地址，<port for icinga2\> 填写 taosAdapter 支持接收 icinga2 数据的相应端口（默认为 6048）

```
object OpenTsdbWriter "opentsdb" {
  host = "<taosAdapter's host>"
  port = <port for icinga2>
}
```

实例文件：

```
object OpenTsdbWriter "opentsdb" {
  host = "127.0.0.1"
  port = 6048
}
```
