Severity: 3-Major


The memory pages available and in use are tracked with system statistics. Previously those statistics were available only with the tmctl command in the shell.


It is not feasible to query each BIG-IP device separately.


When system resource decisions are being made, the information about memory usage is important.



Fix Information

You can query these statistics with SNMP through the F5-BIGIP-SYSTEM-MIB::sysTmmPagesStat table.
