Find Overall CPU Usages<\/h3><\/span>\n
* Use multiple processor stat tool ‘mpstat’
\n* Columns to note
\n– ‘usr’: percent user time
\n– ‘sys’: percent system time
\n– ‘idl’: percent idle time
\n* Example<\/p>\n
\r\n# Generate 2 processor reports with 5 second interval\r\nmpstat 5 2\r\nCPU minf mjf xcal  intr ithr  csw icsw migr smtx  srw syscl  usr sys  wt idl\r\n  0   14   0   42    35   18   48    0    1    8    0   139    1   0   0  99\r\n  1    7   0   27    87   55   65    0    1    8    0    92    0   1   0  99\r\n<\/pre>\n
Find CPU Usage by Processes<\/h3><\/span>\n
* Use process stat tool ‘prstat’
\n* Similar to Linux ‘top’ command
\n* Examples<\/p>\n
\r\n# Sort by cpu usage (default)\r\nprstat \r\n\r\n# Sort by memory usage\r\nprstat -s rss\r\n\r\n# Sort by virtual memory usage\r\nprstat -s size\r\n\r\n# Sort by process execution time\r\nprstat -s time\r\n\r\n# Find top 5 processes\r\nprstat -n 5\r\n\r\n# Also print process numbers each user is using\r\nprstat -a\r\n\r\n# Follow a particular process id\r\nprstat -p pid\r\n\r\n# Follow threads of a particular process id\r\nprstat -L -p pid\r\n<\/pre>\n
Find Paging Activities<\/h3><\/span>\n
* Use system activity report tool ‘sar’
\n* Examples<\/p>\n
\r\n# Find top 3 paging activities with 5 second interval\r\nsar -g 5 3\r\n18:57:12  pgout\/s ppgout\/s pgfree\/s pgscan\/s %ufs_ipf\r\n18:57:17     0.00     0.00     0.00     0.00     0.00\r\n18:57:22     0.00     0.00     0.00     0.00     0.00\r\n18:57:27     0.00     0.00     0.00     0.00     0.00\r\n\r\nAverage      0.00     0.00     0.00     0.00     0.00\r\n\r\n# Total memory\r\n\/usr\/sbin\/prtconf | grep Memory | awk -F\":\" '{print $2}'\r\nMemory size: 8192 Megabytes\r\n\r\n# Find free memory and swap space based on 3 reads with 5 second read intervals\r\nsar -r 5 3\r\n18:56:24 freemem freeswap\r\n18:56:29  175049 28289968\r\n18:56:34  175031 28289843\r\n18:56:39  175026 28289952\r\n\r\nAverage   175036 28289921\r\n<\/pre>\n
