    DESCRIPTION
        "This is a MIB Module for monitoring Firebrick CPU usage."
    REVISION "202006170000Z"
    DESCRIPTION "Initial version of this MIB module"
    ::= { firebrickNewStyle 2 }

fbCpuUsageTable OBJECT-TYPE
    SYNTAX SEQUENCE OF FbCpuUsageEntry
    MAX-ACCESS not-accessible
    STATUS current
    DESCRIPTION
        "The table of CPU usage for this Firebrick"
    ::= { fbCpuMib 1 }

fbCpuUsageEntry OBJECT-TYPE
    SYNTAX FbCpuUsageEntry
    MAX-ACCESS not-accessible
    STATUS current
    DESCRIPTION
        "An entry in the CPU usage table"
    INDEX { fbCpuPeriod, fbCpuCore }
    ::= { fbCpuUsageTable 1 }

FbCpuUsageEntry ::= SEQUENCE {
    fbCpuIRQ      Gauge32,
    fbCpuAll      Gauge32,
    fbCpuIRQPeak  Gauge32,
    fbCpuAllPeak  Gauge32,
    fbCpuPeriod   Integer32,
    fbCpuCore     Integer32
}

fbCpuPeriod OBJECT-TYPE
    SYNTAX Integer32
    MAX-ACCESS not-accessible
    STATUS current
    DESCRIPTION
        "The period in minutes covered by this table entry.
         Zero indicates that an instantaneous value is required."
    ::= { fbCpuUsageEntry 5 }

fbCpuCore OBJECT-TYPE
    SYNTAX Integer32
    MAX-ACCESS not-accessible
    STATUS current
    DESCRIPTION
        "The CPU core number covered by this table entry.
	 The numbering starts at 1, so CPU0 (CORE) is 1 and CPU1 (NET) is 2."
    ::= { fbCpuUsageEntry 6 }

fbCpuIRQ OBJECT-TYPE
    SYNTAX Gauge32
    MAX-ACCESS read-only
    STATUS current
    DESCRIPTION
        "The percentage of CPU time spent in interrupt processing for this period.
	 If period is 0 the instantaneous usage in the last second is used.
	 Units are 100ths of a percent, so 10000 indicates 100%."
    ::= { fbCpuUsageEntry 1 }

fbCpuAll OBJECT-TYPE
    SYNTAX Gauge32
    MAX-ACCESS read-only
    STATUS current
    DESCRIPTION
        "The total percentage of CPU time spent non-idle for this period.
	 If period is 0 the instantaneous usage in the last second is used.
	 Units are 100ths of a percent, so 10000 indicates 100%."
    ::= { fbCpuUsageEntry 2 }

fbCpuIRQPeak OBJECT-TYPE
    SYNTAX Gauge32
    MAX-ACCESS read-only
    STATUS current
    DESCRIPTION
        "The peak percentage of CPU time in interrupt processing during this period.
	 If period is 0 the peak usage in the current minute is used.
	 Units are 100ths of a percent, so 10000 indicates 100%."
    ::= { fbCpuUsageEntry 3 }

fbCpuAllPeak OBJECT-TYPE
    SYNTAX Gauge32
    MAX-ACCESS read-only
    STATUS current
    DESCRIPTION
        "The peak percentage of CPU time non-idle during this period.
	 If period is 0 the peak usage in the current minute is used.
	 Units are 100ths of a percent, so 10000 indicates 100%."
    ::= { fbCpuUsageEntry 4 }
