# tuning plugin
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
This plugin can change some system controls (sysctls) in the network namespace.
|
||
|
|
It does not create any network interfaces and therefore does not bring connectivity by itself.
|
||
|
|
It is only useful when used in addition to other plugins.
|
||
|
|
|
||
|
|
## Operation
|
||
|
|
The following network configuration file
|
||
|
|
```
|
||
|
|
{
|
||
|
|
"name": "mytuning",
|
||
|
|
"type": "tuning",
|
||
|
|
"sysctl": {
|
||
|
|
"net.core.somaxconn": "500"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
will set /proc/sys/net/core/somaxconn to 500.
|
||
|
|
Other sysctls can be modified as long as they belong to the network namespace (`/proc/sys/net/*`).
|
||
|
|
|
||
|
|
A successful result would simply be:
|
||
|
|
```
|
||
|
|
{ }
|
||
|
|
```
|
||
|
|
|
||
|
|
## Network sysctls documentation
