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.

Compatibility

edit

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

Metrics

edit

The below metrics are fetched from memcached:

ECS Field Reference

Please refer to the following document for detailed information on ECS fields.

Exported fields

Field	Description	Type	Unit	Metric Type
@timestamp	Event timestamp.	date
agent.id	Unique identifier of this agent (if one exists). Example: For Beats this would be beat.id.	keyword
cloud.account.id	The cloud account or organization id used to identify different entities in a multi-tenant environment. Examples: AWS account id, Google Cloud ORG Id, or other unique identifier.	keyword
cloud.availability_zone	Availability zone in which this host, resource, or service is located.	keyword
cloud.instance.id	Instance ID of the host machine.	keyword
cloud.provider	Name of the cloud provider. Example values are aws, azure, gcp, or digitalocean.	keyword

container.id	Unique container id.	keyword
data_stream.dataset	Data stream dataset.	constant_keyword
data_stream.namespace	Data stream namespace.	constant_keyword
data_stream.type	Data stream type.	constant_keyword
event.dataset	Event module	constant_keyword
event.kind	Event kind	constant_keyword
event.module	Event module	constant_keyword
event.type	Event type	constant_keyword
host.name	Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name (FQDN), or a name specified by the user. The recommended value is the lowercase FQDN of the host.	keyword
memcached.stats.cmd.get	Number of "get" commands received since server startup not counting if they were successful or not.	long		counter
memcached.stats.cmd.set	Number of "set" commands serviced since server startup.	long		counter
memcached.stats.connections.current	Number of open connections to this Memcached server, should be the same value on all servers during normal operation.	long		counter
memcached.stats.connections.total	Numer of successful connection attempts to this server since it has been started.	long		counter
memcached.stats.current.bytes	Number of bytes currently used for caching items.	long	byte	gauge
memcached.stats.evictions	Number of objects removed from the cache to free up memory for new items when Memcached reaches it’s maximum memory setting (limit_maxbytes).	long		counter
memcached.stats.get.hits	Cache HitRate: Its the ratio of number of successful "get" commands (cache hits) since startup and the "cmd_get" value.	long		gauge
memcached.stats.get.misses	Number of failed "get" requests as nothing was cached for this key or the cached value was too old.	long		counter
memcached.stats.items.current	Number of items currently in this server’s cache.	long		gauge
memcached.stats.items.total	Number of items ever stored on the server. The count increases by every new item stored in the cache.	long		counter
memcached.stats.limit.bytes	Number of bytes the server is allowed to use for storage.	long	byte	gauge
memcached.stats.pid	Current process ID of the Memcached task.	long
memcached.stats.read.bytes	Total number of bytes received by the server from the network.	long	byte	counter
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

Example

An example event for stats looks as following:
