Num Of Free Memory Pages (MEMFreeMem)
This parameter displays the number of 1 KB pages of memory available.
The amount of available free memory is critical for the operating system. If the amount is low and many applications are running, the operating system may start swapping information from main memory to secondary memory. The value of this attribute is calculated with the help of commands like free (Linux) and vmstat (HP, Solaris, and AIX).
When this parameter's value reaches the warning or alarm range, the value is annotated with an asterisk 🟡️ when you display the graph. The annotation contains the value of the PROCTopProcs parameter, which shows the top 10 CPU-using processes.
