UPTIME(1) User Commands UPTIME(1)NAME
uptime - Tell how long the system has been running.
SYNOPSIS
uptime [options]
DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are
currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
This is the same information contained in the header line displayed by w(1).
System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable
state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for
disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a
load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.
OPTIONS -p, --pretty
show uptime in pretty format
-h, --help
display this help text
-s, --since
system up since, in yyyy-mm-dd HH:MM:SS format
-V, --version
display version information and exit
FILES
/var/run/utmp
information about who is currently logged on
/proc process information

So it looks like this

My first question is how to remove the comma behind the... (7 Replies)
hello folks!
how can I display just the uptime without the current time, the word "up", and the load averages using the uptime command or some other command I do not know about? (13 Replies)
I was told that there is a correspondance between the number of cpus, the load averages, and when the cpus reach 100% capacity.
I have 4 cpus and said that once the numbers hit 4.00, my CPUs are 100% at capacity. load average: 0.08, 0.09, 0.11
Is that correct?
Thank you (7 Replies)

Hi,
I am getting a high load average, around 7, once an hour. It last for about 4 minutes and makes things fairly unusable for this time.
How do I find out what is using this. Looking at top the only thing running at the time is md5sum.
I have looked at the crontab and there is nothing... (10 Replies)
Hi!
I want to extract the uptime from the output of the uptime command.
The output:
11:53 up 3:02, 2 users, load averages: 0,32 0,34 0,43
I just need the "3:02" part. How can I do this?

I need to get, in my application, in different methods, the uptime of the system in milliseconds.
time() - returns only seconds.
/proc/uptime - returns the seconds + a truncated milliseconds value, but it need to be parsed to extract data and convert it to milliseconds
Any other suggestions ? (6 Replies)
Hi,
Am writing a script where I want to find uptime of certain servers. Is there any command where we can find uptime without login to the server, since the server list is big logging to the server will time consuming.
Thanks in advance (7 Replies)
need to capture the following data on an hourly basis without cronjob scheduling in Solaris 5.10/5.11:-
1. load averages
2. Total no. of processes.
3. CPU state
4. Memory
5. Top 3 process details.
any other third-party tool is available? (7 Replies)
Hi all,
Been reading a lot of the cpu load and its "analogy of it to car traffic path of expressway"
From wiki
Most UNIX systems count only processes in the running (on CPU) or runnable (waiting for CPU) states. However, Linux also includes processes in uninterruptible sleep states... (13 Replies)
