Memcached-specific event fields
-
memcache.protocol_type -
The memcache protocol implementation. The value can be "binary" for binary-based, "text" for text-based, or "unknown" for an unknown memcache protocol type.
type: keyword
-
memcache.request.line -
The raw command line for unknown commands ONLY.
type: keyword
-
memcache.request.command -
The memcache command being requested in the memcache text protocol. For example "set" or "get". The binary protocol opcodes are translated into memcache text protocol commands.
type: keyword
-

The memcache command classification. This value can be "UNKNOWN", "Load", "Store", "Delete", "Counter", "Info", "SlabCtrl", "LRUCrawler", "Stats", "Success", "Fail", or "Auth".
type: keyword
-
memcache.response.type -
The memcache command classification. This value can be "UNKNOWN", "Load", "Store", "Delete", "Counter", "Info", "SlabCtrl", "LRUCrawler", "Stats", "Success", "Fail", or "Auth". The text based protocol will employ any of these, whereas the binary based protocol will mirror the request commands only (see
