strace: Show the time spent in every system call.
$ strace -p ${pid} -T
try on your machine
The command "strace -p ${pid} -T" is used to attach to a running process with the specified process ID (pid) and trace its system calls while also measuring the time taken by each system call.
Here's a breakdown of the command:
strace
: This is the command used to trace system calls and signals made by a process.-p ${pid}
: This option specifies the process ID (pid) of the process to be traced. Replace "${pid}" with the actual PID of the process you want to trace.-T
: This option is used to print the time taken by each system call. It displays the time in seconds, followed by a decimal point and the number of microseconds.
By using this command, you can monitor the system calls made by a specific process and analyze the time taken by each system call to identify potential bottlenecks and performance issues.
