Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering. As a result of its speed, scalability, simple design, efficient memory management and API support for most popular languages. Memcached is a popular choice for high-performance, large-scale caching use cases.
The Memcached Integration has been tested with 1.5 and 1.6 versions of Memcached. It is expected to work with all versions >= 1.5
The below metrics are fetched from memcached:
ECS Field Reference

| memcached.stats.threads | Number of threads used by the current Memcached server process. | long | counter | |
| memcached.stats.uptime.sec | Memcached server uptime. | long | s | gauge |
| memcached.stats.written.bytes | Total number of bytes sent to the network by the server. | long | byte | counter |
| service.address | Address where data about this service was collected from. This should be a URI, network address (ipv4:port or [ipv6]:port) or a resource path (sockets). | keyword |
