# socket listener service input plugin
|
||||
|
||||
The Socket Listener is a service input plugin that listens for messages from
|
||||
streaming (tcp, unix) or datagram (udp, unixgram) protocols.
|
||||
|
||||
The plugin expects messages in the
|
||||
[Telegraf Input Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
|
||||
|
||||
### Configuration:
|
||||
|
||||
This is a sample configuration for the plugin.
|
||||
|
||||
```toml
|
||||
# Generic socket listener capable of handling multiple socket types.
|
||||
[[inputs.socket_listener]]
|
||||
## URL to listen on
|
||||
# service_address = "tcp://:8094"
|
||||
# service_address = "tcp://127.0.0.1:http"
|
||||
# service_address = "tcp4://:8094"
|
||||
# service_address = "tcp6://:8094"
|
||||
# service_address = "tcp6://[2001:db8::1]:8094"
|
||||
# service_address = "udp://:8094"
|
||||
# service_address = "udp4://:8094"
|
||||
# service_address = "udp6://:8094"
|
||||
# service_address = "unix:///tmp/telegraf.sock"
|
||||
# service_address = "unixgram:///tmp/telegraf.sock"
|
||||
|
||||
## Maximum number of concurrent connections.
|
||||
## Only applies to stream sockets (e.g. TCP).
|
||||
## 0 (default) is unlimited.
|
||||
# max_connections = 1024
|
||||
|
||||
## Maximum socket buffer size in bytes.
|
||||
## For stream sockets, once the buffer fills up, the sender will start backing up.
|
||||
## For datagram sockets, once the buffer fills up, metrics will start dropping.
|
||||
## Defaults to the OS default.
|
||||
# read_buffer_size = 65535
|
||||
|
||||
## Data format to consume.
|
||||
## Each data format has it's own unique set of configuration options, read
|
||||
## more about them here:
|
||||
## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
|
||||
# data_format = "influx"
|
||||
```
|
||||
|
||||
## A Note on UDP OS Buffer Sizes
|
||||
|
||||
The `read_buffer_size` config option can be used to adjust the size of the socket
|
||||
buffer, but this number is limited by OS settings. On Linux, `read_buffer_size`
|
||||
will default to `rmem_default` and will be capped by `rmem_max`. On BSD systems,
|
||||
`read_buffer_size` is capped by `maxsockbuf`, and there is no OS default
|
||||
setting.
|
||||
|
||||
Instructions on how to adjust these OS settings are available below.
|
||||
|
||||
Some OSes (most notably, Linux) place very restricive limits on the performance
|
||||
of UDP protocols. It is _highly_ recommended that you increase these OS limits to
|
||||
at least 8MB before trying to run large amounts of UDP traffic to your instance.
|
||||
8MB is just a recommendation, and can be adjusted higher.
|
||||
|
||||
### Linux
|
||||
Check the current UDP/IP receive buffer limit & default by typing the following
|
||||
commands:
|
||||
|
||||
```
|
||||
sysctl net.core.rmem_max
|
||||
sysctl net.core.rmem_default
|
||||
```
|
||||
|
||||
If the values are less than 8388608 bytes you should add the following lines to
|
||||
the /etc/sysctl.conf file:
|
||||
|
||||
```
|
||||
net.core.rmem_max=8388608
|
||||
net.core.rmem_default=8388608
|
||||
```
|
||||
|
||||
Changes to /etc/sysctl.conf do not take effect until reboot.
|
||||
To update the values immediately, type the following commands as root:
|
||||
|
||||
```
|
||||
sysctl -w net.core.rmem_max=8388608
|
||||
sysctl -w net.core.rmem_default=8388608
|
||||
```
|
||||
|
||||
### BSD/Darwin
|
||||
|
||||
On BSD/Darwin systems you need to add about a 15% padding to the kernel limit
|
||||
socket buffer. Meaning if you want an 8MB buffer (8388608 bytes) you need to set
|
||||
the kernel limit to `8388608*1.15 = 9646900`. This is not documented anywhere but
|
||||
happens
|
||||
[in the kernel here.](https://github.com/freebsd/freebsd/blob/master/sys/kern/uipc_sockbuf.c#L63-L64)
|
||||
|
||||
Check the current UDP/IP buffer limit by typing the following command:
|
||||
|
||||
```
|
||||
sysctl kern.ipc.maxsockbuf
|
||||
```
|
||||
|
||||
If the value is less than 9646900 bytes you should add the following lines
|
||||
to the /etc/sysctl.conf file (create it if necessary):
|
||||
|
||||
```
|
||||
kern.ipc.maxsockbuf=9646900
|
||||
```
|
||||
|
||||
Changes to /etc/sysctl.conf do not take effect until reboot.
|
||||
To update the values immediately, type the following command as root:
|
||||
|
||||
```
|
||||
sysctl -w kern.ipc.maxsockbuf=9646900
|
