# SocketStat plugin
|
||
|
|
|
||
|
|
The socketstat plugin gathers indicators from established connections, using iproute2's `ss` command.
|
||
|
|
|
||
|
|
The `ss` command does not require specific privileges.
|
||
|
|
|
||
|
|
**WARNING: The output format will produce series with very high cardinality.** You should either store those by an engine which doesn't suffer from it, use a short retention policy or do appropriate filtering.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[[inputs.socketstat]]
|
||
|
|
## ss can display information about tcp, udp, raw, unix, packet, dccp and sctp sockets
|
||
|
|
## Specify here the types you want to gather
|
||
|
|
socket_types = [ "tcp", "udp" ]
|
||
|
|
## The default timeout of 1s for ss execution can be overridden here:
|
||
|
|
# timeout = "1s"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Measurements & Fields
|
||
|
|
|
||
|
|
- socketstat
|
||
|
|
- state (string) (for tcp, dccp and sctp protocols)
|
||
|
|
- If ss provides it (it depends on the protocol and ss version):
|
||
|
|
- bytes_acked (integer, bytes)
|
||
|
|
- bytes_received (integer, bytes)
|
||
|
|
- segs_out (integer, count)
|
||
|
|
- segs_in (integer, count)
|
||
|
|
- data_segs_out (integer, count)
|
||
|
|
- data_segs_in (integer, count)
|
||
|
|
|
||
|
|
## Tags
|
||
|
|
|
||
|
|
- All measurements have the following tags:
|
||
|
|
- proto
|
||
|
|
- local_addr
|
||
|
|
- local_port
|
||
|
|
- remote_addr
|
||
|
|
- remote_port
