Practical (Operational) Example
Looking at the % Free Memory for our SmartCell Servers in Figure 11, we can see SmartCell Server
10.0.172.2 has significantly less available memory when compared with the other three SmartCell
servers. While the other three SmartCell servers are running at approximately 32% Free memory,
SmartCell server 10.0.172.2 has been running at 10% Free Memory since sometime before the 21
st
of November.
Figure 11. SmartCell (10.0.172.2) 10% Free Memory
Note: This is not necessarily an indication of a problem, since Linux systems will often consume 90%
of memory for caching and other processes. The unused committed memory is released as new or
current processes request additional memory. In this example, the system services were restarted to
highlight the release of committed memory illustrated in the graph. As explained above, this is not
necessarily indicative of a problem. Production systems should not be restarted simply to release
committed memory.
In an attempt to release some of the committed memory, we went into the Platform Control option of
the PCC, selected Machine, chose the sc-s1-172-2, and then selected Restart for the Action and Run
