RFE: new system metric "memAvailable"
Is your feature request related to a problem? Please describe.
From support case 1-7785570312, I had the information that the value (and specially the trend) of memAvailable is important to track. For reference (from that case):
There is an RFE to change the memory monitoring to track MemAvailable - which is more relevant in BIG-IP devices with versions after 13.1:
ID1043485 Memory reporting should include and be based on MemAvailable
According to that enhancement, the swap Use graph should be removed as it is less relevant in supported versions of BIG-IP after 13.1.
Describe the solution you'd like
add a metric system.memAvailable. Value is found from /proc/meminfo:
