- What do real, user and sys mean in the output of time(1)?
Not precisely on topic, nevertheless: Running "\time <cmd>" is interesting - it provides more detail: (forgive poor formatting in the comment): $ time ps PID TTY TIME CMD 9437 pts 19 00:00:00 bash 11459 pts 19 00:00:00 ps real 0m0 025s user 0m0 004s sys 0m0 018s $ \time ps PID TTY TIME CMD 9437 pts 19 00:00:00 bash 11461 pts 19 00:00:00 time 11462 pts 19 00:00:00 ps 0 00user 0 01system 0:00
- User CPU time vs System CPU time? - Stack Overflow
The term ‘user CPU time’ can be a bit misleading at first To be clear, the total time (real CPU time) is the combination of the amount of time the CPU spends performing some action for a program and the amount of time the CPU spends performing system calls for the kernel on the program’s behalf
- How to measure user system cpu time for a piece of program?
In section 3 9 of the classic APUE(Advanced Programming in the UNIX Environment), the author measured the user system time consumed in his sample program which runs against varying buffer size(an I O
- Prometheus - Convert cpu_user_seconds to CPU Usage
Note that container_cpu_user_seconds_total and container_cpu_system_seconds_total are per-container counters, which show CPU time used by a particular container in user space and in kernel space accordingly (see these docs for more details) Cadvisor exposes additional metric - container_cpu_usage_seconds_total
- What unit is used to display Redis CPU usage - Stack Overflow
I ran the command INFO CPU in the Redis CLI and got the output shown below: used_cpu_sys:4785 73 used_cpu_user:4843 73 used_cpu_sys_children:0 00 used_cpu_user_children:0 00 My question is: what i Skip to main content
- performance - Why real time is much higher than user and system CPU . . .
We have a batch process that executes every day This week, a job that usually does not past 18 minutes of execution time (real time, as you can see), now is taking more than 45 minutes to finish
- Teradata : Query to find CPU utilization user level (History data)
I have the query to find the current CPU and IO utilization at user level Query SELECT ACCOUNTNAME, USERNAME, SUM(CPUTIME) AS CPU, SUM(DISKIO) AS DISKIO FROM DBC AMPUSAGE GROUP BY 1,2 ORDER BY 3 DESC
- Limit the memory and cpu available for a user in Linux
I am a little concerned with the amount of resources that I can use in a shared machine Is there any way to test if the administrator has a limit in the amount of resources that I can use?
- What specifically are wall-clock-time, user-cpu-time, and system-cpu . . .
@Bionix1441: You cannot derive elapsed time from CPU time for a number of reasons First, a process can be idle, not consuming any CPU time, for arbitrary periods (for example, a daemon process waiting for a client to connect to it over the network), so it may do nothing for days at a time of elapsed time
- What do the user CPU time and system CPU time in getrusage (RUSAGE . . .
No, in general the blocked time won't be assigned to user or kernel CPU time (which is what rusage measures)
