# Memcache Check

## Overview

The Agent's memcache check lets you track memcache's memory use, hits, misses, evictions, fill percent, and much more.

## Setup
### Installation

The memcache check is packaged with the Agent, so simply [install the Agent][1] on your memcache servers.

### Configuration

Create a file `mcache.yaml` in the Agent's `conf.d` directory.See the [sample mcache.yaml][2] for all available configuration options:

```
init_config:

instances:
  - url: localhost  # url used to connect to the memcached instance
    port: 11212 # optional; default is 11211
#    socket: /path/to/memcache/socket # alternative to url/port; 'dd-agent' user must have read/write permission
    options:
      items: false # set to true to collect items stats
      slabs: false # set to true to collect slabs stats
#    tags:
#    - optional_tag
```

[Restart the Agent][3] to begin sending memcache metrics to Datadog.

### Validation

[Run the Agent's `status` subcommand][4] and look for `mcache` under the Checks section.

## Data Collected
### Metrics

See [metadata.csv][5] for a list of metrics provided by this check.

The check only collects `memcache.slabs.*` metrics if you set `options.slabs: true` in `mcache.yaml`. Likewise, it only collects `memcache.items.*` metrics if you set `options.items: true`.


### Events
The Mcache check does not include any event at this time.

### Service Checks

`memcache.can_connect`:

Returns CRITICAL if the Agent cannot connect to memcache to collect metrics, otherwise OK.

## Troubleshooting
