# Network Connection Statistics Input Plugin
|
|
|
|
This plugin collects statistics about TCP connection states and UDP socket
|
|
counts.
|
|
|
|
⭐ Telegraf v0.2.0

|
|
|
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
|
|
|
In addition to the plugin-specific configuration settings, plugins support
|
|
additional global and plugin configuration settings. These settings are used to
|
|
modify metrics, tags, and field or create aliases and configure ordering, etc.
|
|
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
|
|
|
|
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
|
|
|
|
## Configuration
|
|
|
|
```toml @sample.conf
|
|
# Read TCP metrics such as established, time wait and sockets counts.
|
|
[[inputs.netstat]]
|
|
# no configuration
|
|
```
|
|
|
|
## Metrics
|
|
|
|
Supported TCP Connection states are follows.
|
|
|
|
- established
|
|
- syn_sent
|
|
- syn_recv
|
|
- fin_wait1
|
|
- fin_wait2
|
|
- time_wait
|
|
- close
|
|
- close_wait
|
|
- last_ack
|
|
- listen
|
|
- closing
|
|
- none
|
|
|
|
### TCP Connection State measurements
|
|
|
|
Meta:
|
|
|
|
- units: counts
|
|
|
|
Measurement names:
|
|
|
|
- tcp_established
|
|
- tcp_syn_sent
|
|
- tcp_syn_recv
|
|
- tcp_fin_wait1
|
|
- tcp_fin_wait2
|
|
- tcp_time_wait
|
|
- tcp_close
|
|
- tcp_close_wait
|
|
- tcp_last_ack
|
|
- tcp_listen
|
|
- tcp_closing
|
|
- tcp_none
|
|
|
|
If there are no connection on the state, the metric is not counted.
|
|
|
|
### UDP socket counts measurements
|
|
|
|
Meta:
|
|
|
|
- units: counts
|
|
|
|
Measurement names:
|
|
|
|
- udp_socket
|
|
|
|
## Example Output
|
|
|
|
```text
|
|
netstat tcp_close=0i,tcp_close_wait=0i,tcp_closing=0i,tcp_established=14i,tcp_fin_wait1=0i,tcp_fin_wait2=0i,tcp_last_ack=0i,tcp_listen=1i,tcp_none=46i,tcp_syn_recv=0i,tcp_syn_sent=0i,tcp_time_wait=0i,udp_socket=10i 1668520568000000000
