In this post we are going to see about how to check top process in solaris.While there are many tools available to check top process but we are going to have focus on two commands.
First Command in our list prstat command in solaris and 2nd command will be ps command in solaris.

prstat command in solaris
prstat command in solaris is especially available for system administrators .It comes under system administration category of command. prstat utility is really handy and especially designed for process monitoring.
Let us see small portion of prstat man command to see what are the options available.Since man page of prstat is too long so it is not feasible to add too long man page output.
# man prstat Reformatting page. Please Wait... done System Administration Commands prstat(1M) NAME prstat - report active process statistics SYNOPSIS prstat [-acHJLmRtTv] [-C psrsetlist] [-h lgrplist] [-j projlist] [-k tasklist] [-n ntop[,nbottom]] [-p pidlist] [-P cpulist] [-s key | -S key ] [-u euidlist] [-U uidlist] [-z zoneidlist] [-Z] [interval [count]] DESCRIPTION The prstat utility iteratively examines all active processes on the system and reports statistics based on the selected output mode and sort order. prstat provides options to examine only processes matching specified PIDs, UIDs, zone IDs,CPU IDs, and processor set IDs. The -j, -k, -C, -p, -P, -u, -U, and -z options accept lists as arguments. Items in a list can be either separated by commas or enclosed in quotes and separated by commas or spaces. If you do not specify an option, prstat examines all processes and reports statistics sorted by CPU usage.
How to find top 10 most active process on CPU
Below command will give the 10 most active process by root ID on CPU1 & CPU2.Syntax of command will be like below.
# prstat -u <ID> -n 10 -P CPU1,CPU2 1 1 # prstat -u root -n 10 -P 1,2 1 1 PID USERNAME SWAP RSS STATE PRI NICE TIME CPU PROCESS/LWP 306 root 3024K 1448K sleep 58 0 0:00.00 0.3% sendmail/1 102 root 1600K 592K sleep 59 0 0:00.00 0.1% in.rdisc/1 250 root 1000K 552K sleep 58 0 0:00.00 0.0% utmpd/1 288 root 1720K 1032K sleep 58 0 0:00.00 0.0% sac/1 1 root 744K 168K sleep 58 0 0:00.00 0.0% init/1 TOTAL: 25, load averages: 0.05, 0.08, 0.12
Please refer to output it will also show how many process is running on server and load average.So you may find the reason from here if any specific process is consuming CPU resource.
How to find top 10 Process usage in Verbose
prstat command in solaris with below switch will displays verbose process usage information about processes with lowest resident set sizes owned by user root.
# prstat -S rss -n 10 -vc -u root PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX ICX SCL SIG PROCESS 1 root 0.0 0.0 - - - - 100 - 0 0 0 0 init/1 102 root 0.0 0.0 - - - - 100 - 0 0 3 0 in.rdisc/1 102 root 0.0 0.0 - - - - 100 - 0 0 3 0 in.rdisc/1 250 root 0.0 0.0 - - - - 100 - 0 0 0 0 utmpd/1 240 root 0.0 0.0 - - - - 100 - 0 0 0 0 powerd/4 TOTAL: 71, load averages: 0.02, 0.04, 0.08 EXIT STATUS The following exit values are returned:0 for Successful completion and 1 for an error occurred.
So let us see some other switch options you can take to have more clear view on cpu utilization.

How to check top 10 CPU Consuming Process in Solaris
Well lets finish review of prstat command with bingo kind of options which will give you very clear idea what is happening with server.You will get top 10 CPU Consuming Process in Solaris.
# prstat -s cpu -a -n 10

Total: 104 processes, 415 lwps, load averages: 1.25, 1.16, 1.14
This looks amazing right first it will display top 10 cpu consuming process in solaris and down to it how much resources used by each process in terms of CPU Memory SWAP and also number of process is running by each process.
ps command in solaris
Please refer to below snap of man page for ps which clearly shows this is for getting process status.
# man ps Reformatting page. Please Wait... done NAME ps - report process status SYNOPSIS ps [-aAcdefjlLPyZ] [-g grplist] [-n namelist] [-o format] [-p proclist] [-s sidlist] [-t term] [-u uidlist] [-U uidlist] [-G gidlist] [-z zonelist] DESCRIPTION The ps command prints information about active processes.Without options, ps prints information about processes that have the same effective user ID and the same controlling terminal as the invoker. The output contains only the process ID, terminal identifier, cumulative execution time, and the command name. Otherwise, the information that is displayed is controlled by the options. Some options accept lists as arguments. Items in a list can be either separated by commas or else enclosed in quotes and separated by commas or spaces. Values for proclist and grplist must be numeric.
Let us see few ps command in solaris examples

So we have gone through and seen how these two commands in solaris can help you to find the answer to how to check top process in solaris.
