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.status for 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

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.response field will be missing.

type: boolean

memcache.request.quiet

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
