How is memory utilization percentage calculated?
Keeping in mind the formula, MEM%= 100-(((free+buffers+cached)*100)/TotalMemory).
Where is memory utilization in Solaris 10?
Different Ways to Check Memory Usage on Solaris Server
- echo ::memstat | mdb –k. # echo ::memstat | mdb -k.
- prstat –t. Instead of command “prstat”, which report active process statistics, command prstat with opetion “-t” can report total usage summary for each user.
- ps -efo pmem,uid,pid,ppid,pcpu,comm | sort -r.
How to check the memory usage in Solaris?
In prstat output, the SWAP column shows the virtual memory used and the RSS column, the RAM used. About kernel usage, you can run kstat -n system_pages and have a look to the pp_kernel value.
How to monitor memory usage / performance in SunOS?
Beware that Solaris uses the swap term to either name the part of disk used to store memory pages that are paged out from RAM or to name the whole virtual memory space, i.e. the swap area plus the part of RAM that is not locked there. Not as detailed as your Linux example but you could use the ::memstat macro in mdb:
How is swap and as / TMP calculated in Solaris?
Solaris uses the memory as /tmp and swap will be calculated along with physical memory. We need to use the right commands to figure out the utilization of both. “top” is one if the best monitoring tool but it’s not inbuilt in Solaris 10.
Which is the best vmstat command for Solaris?
