Description

This role installs and configures memcached and memcached_exporter services.

The exporter is available on port 9150 and the prometheus metrics can be fetched via the /metrics http endpoint:

curl 0.0.0.0:9150/metrics

Configuration

The defaults are sane, but the basics would be:

memcached_addr: '127.0.0.1'
memcached_port: 11211
memcached_size_mb: 64
memcached_maxconn: 1024

The installation of memcached_exporter is optional. It is installed by default but can be disabled by setting:

memcached_exporter_enabled: false
