# value

Counts only messages where the selected key equals the specified value.

This parameter applies to mmcount.

Name:

  value

Scope:

  input

Type:

  word

Default:

  none (count every observed key value)

Required?:

  no

Introduced:

  7.5.0

## Description

Limits counting to a specific property value when combined with key. After appName matches and the requested key is present, mmcount compares the property’s string representation with `value`. If they are equal, a dedicated counter is incremented and stored in the message’s `mmcount` property. Messages that do not match are left unchanged. When `value` is not provided, mmcount maintains separate counters for each property value instead.

Specifying `value` without key has no practical effect; in that case the module still counts messages per severity.

## Input usage

    action(type="mmcount" appName="glusterfsd" key="!gf_code" value="9999")
