BigIP F5 models in Spectrum showing memory threshold of 99% consistently
Spectrum uses the sysMultiHostUsed (Spectrum attribute id 0x3b71af3) and sysMultiHostTotal (Spectrum attribute id 0x3b71af2) to compute memory on the F5 devices. These attributes are defined in the F5-BIGIP-SYSTEM-MIB as follows:
sysMultiHostTotal OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The total host memory in bytes (not including TMM) for the specified host."
::= { sysMultiHostEntry 2 }
sysMultiHostUsed OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The host memory in bytes currently in use (not including TMM) for the specified host."
::= { sysMultiHostEntry 3 }
Manually computing memory based on these attribute values shows Spectrum is computing memory correctly according.
No resolution in Spectrum as Spectrum is computing memory correctly based on the values read from the device for the sysMultiHostUsed and sysMultiHostTotal attributes.
