How is Memory Utilization calculated for AIX server?
Memory Utilization (%) = (Total Memory - Free Memory) / Total Memory where Free Memory = Free + Buffers + Cached
In Telnet/SSH mode:
We are using svmon -G command to get the memory usage value. For example consider the below output:
Physical Memory Usage:
Total Memory = 1957888 (Line 2, Token 2)
Used Memory = 612143 (Line 6, Token 2)
Used (%) = (Used Memory / Total Memory) * 100 = 31.26 %
How is CPU Utilization calculated for AIX server?
CPU Utilization We use the following methods of calculation for CPU Utilization when lparstat command is supported: Method 1: If 'type=Dedicated', then we use the vmstat command output. (i.e) cpu=100-Idle Time Method 2: If ...
How is Memory Utilization calculated for FreeBSD server?
Memory Utilization is calculated using the below formula: Memory Utilization (%) = (used / total) * 100 where, used - Used Memory total - Total Memory Telnet/SSH mode In Telnet/SSH mode, we use the following commands to obtain the memory usage ...
How is Memory Utilization calculated for Linux server?
Formula : Memory Utilization (%) = 100 -(((MemFree + Buffers + Cached)*100)/maxValue) In Telnet/SSH mode: We are using free -b command to get the memory usage for Linux server. Assume the output below, # free -b total ...
How is Memory Utilization calculated in SUN Solaris server?
Memory Calculation We run the below command to check if the SUN server is a zone-supported server: /usr/bin/prstat -n 1 -Z 1 1 2> /dev/null|grep -v "PID"|grep -v "Total:" If the command gives the proper output then we conclude that the server is ...
How is CPU Utilization calculated in the SUN Solaris Server?
In SUN Solaris Server, CPU Utilization is calculated based on Idlecputime. Idlecputime is calculated from the command vmstat 1 3 and it is subtracted from 100 to find the CPUUtilization.
