Memcache Fields

edit

Memcached-specific event fields

memcache.protocol_type

edit

type: string

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

edit

type: string

The raw command line for unknown commands ONLY.

memcache.request.command

edit

type: string

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

edit

type: string

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

memcache.request.type

edit

type: string

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

memcache.response.type

edit

type: string

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

edit

type: string

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

memcache.request.opcode

edit

type: string

The binary protocol message opcode name.

memcache.response.opcode

edit

type: string

The binary protocol message opcode name.

memcache.request.opcode_value

edit

type: int

The binary protocol message opcode value.

memcache.response.opcode_value

edit

type: int

The binary protocol message opcode value.

memcache.request.opaque

edit

type: int

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

memcache.response.opaque

edit

type: int

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

memcache.request.vbucket

edit

type: int

The vbucket index sent in the binary message.

memcache.response.status

edit

type: string

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

memcache.response.status_code

edit

type: int

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

memcache.request.keys

type: list

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

memcache.response.keys

edit

type: list

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

memcache.request.count_values

type: int

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

edit

type: int

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

edit

type: list

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

memcache.response.values

edit

type: list

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

memcache.request.bytes

edit

type: int

The byte count of the values being transfered.

memcache.response.bytes

edit

type: int

memcache.request.flags

edit

type: int

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

memcache.response.flags

edit

type: int

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

memcache.request.exptime
