# Mcrouter Input Plugin
|
||||
|
||||
This plugin gathers statistics data from [Mcrouter][mcrouter] instances, a
|
||||
protocol router, developed and maintained by Facebook, for scaling
|
||||
[memcached][memcached] deployments.
|
||||
|
||||
⭐ Telegraf v1.7.0
|
||||
🏷️ applications, network
|
||||
💻 all
|
||||
|
||||
[mcrouter]: https://github.com/facebook/mcrouter
|
||||
[memcached]: http://memcached.org/
|
||||
|
||||
## 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 metrics from one or many mcrouter servers.
|
||||
[[inputs.mcrouter]]
|
||||
## An array of address to gather stats about. Specify an ip or hostname
|
||||
## with port. ie tcp://localhost:11211, tcp://10.0.0.1:11211, etc.
|
||||
servers = ["tcp://localhost:11211", "unix:///var/run/mcrouter.sock"]
|
||||
|
||||
## Timeout for metric collections from all servers. Minimum timeout is "1s".
|
||||
# timeout = "5s"
|
||||
```
|
||||
|
||||
