Memcached-specific event fields

memcache.protocol_type

type: keyword

The memcache protocol implementation. The value can be "binary" for binary-based, "text" for text-based, or "unknown" for an unknown memcache protocol type.

memcache.request.line

type: keyword

The raw command line for unknown commands ONLY.

memcache.request.command

type: keyword

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.

memcache.response.command

type: keyword

Either the text based protocol response message type or the name of the originating request if binary protocol is used.

memcache.request.type

type: keyword

The memcache command classification. This value can be "UNKNOWN", "Load", "Store", "Delete", "Counter", "Info", "SlabCtrl", "LRUCrawler", "Stats", "Success", "Fail", or "Auth".

memcache.response.type

type: keyword

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).

memcache.response.error_msg

type: keyword

The optional error message in the memcache response (text based protocol only).

memcache.request.opcode

type: keyword

The binary protocol message opcode name.

memcache.response.opcode

type: keyword

The binary protocol message opcode name.

memcache.request.opcode_value

type: long

The binary protocol message opcode value.

memcache.response.opcode_value

type: long

The binary protocol message opcode value.

memcache.request.opaque

type: long

The binary protocol opaque header value used for correlating request with response messages.

memcache.response.opaque

type: long

The binary protocol opaque header value used for correlating request with response messages.

memcache.request.vbucket

type: long

The vbucket index sent in the binary message.

memcache.response.status

type: keyword

The textual representation of the response error code (binary protocol only).

memcache.response.status_code

type: long

The status code value returned in the response (binary protocol only).

memcache.request.keys

type: array

The list of keys sent in the store or load commands.

memcache.response.keys

type: array

The list of keys returned for the load command (if present).

memcache.request.count_values

type: long

The number of values found in the memcache request message. If the command does not send any data, this field is missing.

memcache.response.count_values

type: long

The number of values found in the memcache response message. If the command does not send any data, this field is missing.

memcache.request.values

type: array

The list of base64 encoded values sent with the request (if present).

memcache.response.values

type: array

The list of base64 encoded values sent with the response (if present).

memcache.request.bytes

type: long

format: bytes

The byte count of the values being transferred.

memcache.response.bytes

type: long

format: bytes

The byte count of the values being transferred.

memcache.request.delta

type: long

The counter increment/decrement delta value.

memcache.request.initial

type: long

The counter increment/decrement initial value parameter (binary protocol only).

memcache.request.verbosity

type: long

The value of the memcache "verbosity" command.

memcache.request.raw_args

type: keyword

The text protocol raw arguments for the "stats …​" and "lru crawl …​" commands.

memcache.request.source_class

type: long

The source class id in slab reassign command.

memcache.request.dest_class

type: long

The destination class id in slab reassign command.

memcache.request.automove

type: keyword

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.

memcache.request.flags

type: long

The memcache command flags sent in the request (if present).

memcache.response.flags

type: long

The memcache message flags sent in the response (if present).

memcache.request.exptime

type: long

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).

memcache.request.sleep_us

type: long

The sleep setting in microseconds for the lru_crawler sleep command.

memcache.response.value

type: long

The counter value returned by a counter operation.

memcache.request.noreply

type: boolean

Set to true if noreply was set in the request. The memcache.response field will be missing.

memcache.request.quiet

type: boolean

Set to true if the binary protocol message is to be treated as a quiet message.

memcache.request.cas_unique

type: long

The CAS (compare-and-swap) identifier if present.

memcache.response.cas_unique

type: long

The CAS (compare-and-swap) identifier to be used with CAS-based updates (if present).

memcache.response.stats

The list of statistic values returned. Each entry is a dictionary with the fields "name" and "value".

memcache.response.version

type: keyword

The returned memcache version string.
