Memcache fields
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
memcache.response.command- Either the text based protocol response message type or the name of the originating request if binary protocol is used.
type: keyword
memcache.request.type- 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
memcache.response.statusfor binary protocol).
type: keyword
memcache.response.error_msg- The optional error message in the memcache response (text based protocol only).
type: keyword
memcache.request.opcode- The binary protocol message opcode name.
type: keyword
memcache.response.opcode- The binary protocol message opcode name.
type: keyword
memcache.request.opcode_value- The binary protocol message opcode value.
type: long
memcache.response.opcode_value- The binary protocol message opcode value.
type: long
memcache.request.opaque- The binary protocol opaque header value used for correlating request with response messages.
type: long
memcache.response.opaque- The binary protocol opaque header value used for correlating request with response messages.
type: long
memcache.request.vbucket- The vbucket index sent in the binary message.
type: long
memcache.response.status- The textual representation of the response error code (binary protocol only).
type: keyword
memcache.response.status_code- The status code value returned in the response (binary protocol only).
type: long
memcache.request.keys- The list of keys sent in the store or load commands.
type: array
memcache.response.keys- The list of keys returned for the load command (if present).
type: array
memcache.request.count_values- The number of values found in the memcache request message. If the command does not send any data, this field is missing.
type: long
memcache.response.count_values- The number of values found in the memcache response message. If the command does not send any data, this field is missing.
type: long
memcache.request.values- The list of base64 encoded values sent with the request (if present).
type: array
memcache.response.values- The list of base64 encoded values sent with the response (if present).
type: array
memcache.request.bytes- The byte count of the values being transferred.
type: long
format: bytes
memcache.response.bytes- The byte count of the values being transferred.
type: long
format: bytes
memcache.request.delta- The counter increment/decrement delta value.
type: long
memcache.request.initial- The counter increment/decrement initial value parameter (binary protocol only).
type: long
memcache.request.verbosity- The value of the memcache "verbosity" command.
type: long
memcache.request.raw_args- The text protocol raw arguments for the "stats …" and "lru crawl …" commands.
type: keyword
memcache.request.source_class- The source class id in slab reassign command.
type: long
memcache.request.dest_class- The destination class id in slab reassign command.
type: long
memcache.request.automove- The automove mode in the slab automove command expressed as a string. This value can be "standby"(=0), "slow"(=1), "aggressive"(=2), or the raw value if the value is unknown.
type: keyword
memcache.request.flags- The memcache command flags sent in the request (if present).
type: long
memcache.response.flags- The memcache message flags sent in the response (if present).
type: long
memcache.request.exptime- The data expiry time in seconds sent with the memcache command (if present). If the value is <30 days, the expiry time is relative to "now", or else it is an absolute Unix time in seconds (32-bit).
type: long
memcache.request.sleep_us- The sleep setting in microseconds for the lru_crawler sleep command.
type: long
memcache.response.value- The counter value returned by a counter operation.
type: long
memcache.request.noreply- Set to true if noreply was set in the request. The
memcache.responsefield will be missing.
type: boolean
memcache.request.quiet- Set to true if the binary protocol message is to be treated as a quiet message.
type: boolean
memcache.request.cas_unique- The CAS (compare-and-swap) identifier if present.
type: long
memcache.response.cas_unique- The CAS (compare-and-swap) identifier to be used with CAS-based updates (if present).
type: long
memcache.response.stats- The list of statistic values returned. Each entry is a dictionary with the fields "name" and "value".
type: array
memcache.response.version- The returned memcache version string.
type: keyword
