This template computes computation memory using the vmstat command. It extracts the following values from vmstat
- memory pages
- free pages
- numperm percentage
and calculates computation memory as the follows
100*(memory pages - free pages - (numperm percentage*memory pages/100)/(memory pages)
It returns the following statistics
- Memory Pages
- Free Pages
- Non-computation Memory %
- Computational Memory %
For v6.1 and above, it **should** be readily available in the vmstat output. You can modify the script as follows
vmstat -v | grep "percentage of memory used for computational pages" | awk '{ print "Statistic:"$1 }'
