### Configuring taosAdapter
|
|
|
|
To configure taosAdapter to receive collectd data.
|
|
|
|
- Enable the configuration item in the taosAdapter configuration file (default location is /etc/taos/taosadapter.toml)
|
|
|
|
```
|
|
...
|
|
[opentsdb_telnet]
|
|
enable = true
|
|
maxTCPConnections = 250
|
|
tcpKeepAlive = false
|
|
dbs = ["opentsdb_telnet", "collectd", "icinga2", "tcollector"]
|
|
ports = [6046, 6047, 6048, 6049]
|
|
user = "root"
|
|
password = "taosdata"
|
|
...
|
|
```
|
|
|
|
The default database name written by taosAdapter is `collectd`. You can also modify the taosAdapter configuration file dbs entry to specify a different name. user and password are the values configured by the actual TDengine. After changing the configuration file, you need to restart the taosAdapter.
|
|
|
|
- You can also enable the taosAdapter to receive collectd data by using the taosAdapter command-line parameters or by setting environment variables.
|
|
|
|
### Configure collectd
|
|
#collectd
|
|
collectd uses a plugin mechanism to write the collected monitoring data to different data storage software in various forms. tdengine supports both direct collection plugins and write_tsdb plugins.
|
|
|
|
#### Configure the direct collection plugin
|
|
|
|
Modify the relevant configuration items in the collectd configuration file (default location /etc/collectd/collectd.conf).
|
|
|
|
```text
|
|
LoadPlugin network
|
|
<Plugin network>
|
|
Server "<taosAdapter's host>" "<port for collectd direct>"
|
|
</Plugin>
|
|
```
|
|
|
|
where <taosAdapter's host\> fills in the server's domain name or IP address running taosAdapter. <port for collectd direct\> fills in the port that taosAdapter uses to receive collectd data (default is 6045).
|
|
|
|
An example is as follows.
|
|
|
|
```text
|
|
LoadPlugin network
|
|
<Plugin network
|
|
Server "127.0.0.1" "6045"
|
|
</Plugin>
|
|
```
|
|
|
|
#### Configure write_tsdb plugin data
|
|
|
|
Modify the relevant configuration items in the collectd configuration file (default location /etc/collectd/collectd.conf).
|
|
|
|
```text
|
|
LoadPlugin write_tsdb
|
|
<Plugin write_tsdb>
|
|
<Node>
|
|
Host "<taosAdapter's host>"
|
|
Port "<port for collectd write_tsdb plugin>"
|
|
...
|
|
</Node>
|
|
</Plugin>
|
|
```
|
|
|
|
Where <taosAdapter's host\> is the domain name or IP address of the server running taosAdapter. <port for collectd write_tsdb plugin\> Fill in the data that taosAdapter uses to receive the collectd write_tsdb plugin (default is 6047).
|
|
|
|
```text
|
|
LoadPlugin write_tsdb
|
|
<Plugin write_tsdb>
|
|
<Node>
|
|
Host "127.0.0.1"
|
|
Port "6047"
|
|
HostTags "status=production"
|
|
StoreRates false
|
|
AlwaysAppendDS false
|
|
</Node
|
|
</Plugin>
|
|
```
|
|
|
|
Then restart collectd.
|
|
|
|
```
|
|
systemctl restart collectd
|
|
```
|
