==========

* Telegraf v1.7.0+

[Plugin source](https://github.com/influxdata/telegraf/tree/v1.39.0/plugins/inputs/mcrouter/)[Download configuration](https://raw.githubusercontent.com/influxdata/telegraf/refs/tags/v1.39.0/plugins/inputs/mcrouter/sample.conf)

# Mcrouter Input Plugin

This plugin gathers statistics data from [Mcrouter](https://github.com/facebook/mcrouter) instances, a
protocol router, developed and maintained by Facebook, for scaling[memcached](http://memcached.org/) deployments.

**Introduced in:** Telegraf v1.7.0**Tags:** applications, network**OS support:** all

## Global configuration options

Plugins support additional global and plugin configuration settings for tasks
such as modifying metrics, tags, and fields, creating aliases, and configuring
plugin ordering. See [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.

## Configuration

```toml
# 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"
```

## Metrics

The fields from this plugin are gathered in the *mcrouter* measurement.

Description of gathered fields can be found in the [project wiki](https://github.com/facebook/mcrouter/wiki/Stats-list).

Fields:

* uptime
* num\_servers
* num\_servers\_new
* num\_servers\_up
* num\_servers\_down

* destination\_requests\_sum
* outstanding\_route\_get\_reqs\_queued
* outstanding\_route\_update\_reqs\_queued
* outstanding\_route\_get\_avg\_queue\_size
* outstanding\_route\_update\_avg\_queue\_size
* outstanding\_route\_get\_avg\_wait\_time\_sec
* outstanding\_route\_update\_avg\_wait\_time\_sec
* retrans\_closed\_connections
* destination\_pending\_reqs
* destination\_inflight\_reqs
* destination\_batch\_size
* asynclog\_requests
* proxy\_reqs\_processing
* proxy\_reqs\_waiting
* client\_queue\_notify\_period
* rusage\_system
* rusage\_user
* ps\_num\_minor\_faults
* ps\_num\_major\_faults
* ps\_user\_time\_sec
* ps\_system\_time\_sec
* ps\_vsize

* cmd\_get\_out\_all
* cmd\_get\_out
* cmd\_lease\_set\_count
* cmd\_other\_out\_all
* cmd\_lease\_get\_out
* cmd\_set\_count
* cmd\_lease\_set\_out
* cmd\_delete\_count
* cmd\_other

* cmd\_delete\_out\_all
* cmd\_lease\_set\_out\_all

## Tags

* Mcrouter measurements have the following tags:
  * server (the host name from which metrics are gathered)
