now here in this video we are going to
0:02
talk about how we can check the system
0:04
performance into the Linux operating
0:06
system into Windows we have the task
0:08
manager which we can use to check for
0:11
the what are the processing going on
0:12
which are the service is running but
0:14
what if I want to check into the Linux
0:16
operating system which is very important
0:18
to check the state of your system so
0:20
here for performing or we can say what
0:22
are the tasks for what I did II wises
0:25
all the resources we are using into the
0:27
Linux operating system which we have
0:28
which we can monitor are your CPU your
0:32
memory disk paces communication lines
0:36
your i/o time that is your input-output
0:39
time network time and your application
0:41
programs we do have installed into a
0:43
Linux operating system this resources
0:46
can be monitored where we can check for
0:47
your state of this CPU like what the CPU
0:51
is performing how many process it is
0:53
performing what is the ratio of the CPU
0:55
has been utilized which is this free
0:57
space whether the CPU is getting heated
0:59
or not so the whole state of the CPU can
1:02
be checked along with that we can also
1:05
check for the system state CPU so the
1:08
system space a CPU will also check how
1:10
many times we have spent for this system
1:13
utilization from this CPU so like system
1:17
also haves is a monster of the task
1:18
which get performed into the back end
1:20
now if I want to check which are the
1:23
processes which your sleep is handling
1:25
into background for the system those
1:27
particular percentage of usage of this
1:29
particular participe you also we can get
1:32
into the system States if you process
1:33
also we can check for the network input
1:36
output and your time of yours particular
1:40
network so how many packets has come and
1:43
how many packets has gone out into the
1:44
network and what are the timings of
1:46
those particular resource consumption
1:48
over the network we can also check over
1:50
here next is your virtual memory
1:54
performance now if suppose you already
1:56
have your completely network configured
1:59
into the system or you can see a virtual
2:01
memory you have assigned to your systems
2:03
like your swap memory which we can call
2:05
as those particular include including
2:08
the scrapping of this space now when we
2:10
use this virtual memory is if suppose I
2:13
have
2:13
- 2gb of RAM into my system but my
2:16
system requires more RAM
2:18
I generally allocate some space into my
2:21
hard disk so that this particular space
2:22
can be used by my RAM when it is running
2:25
out of space though space are called as
2:28
the what should memory so don't wash
2:30
your memory we can see when your RAM has
2:32
switched to this virtual memory and that
2:35
is called as the swapping like we can
2:36
use those particular virtual memory as a
2:38
RAM and then relative on we can release
2:40
it for the hard disk usage so those are
2:42
called as a virtual memory so how much
2:44
of virtual memory we have used whether
2:47
it is in use or not everything we can
2:49
see into the virtual memory processes
2:51
next we have that'ss application or
2:53
program exits we can check for the
2:55
programs or the applications whether it
2:58
is running during we have started great
3:00
operating system now most of the times
3:02
it happens like you are running some
3:03
program and pulls that when you restart
3:06
the machine you won't find this
3:07
particular program or this service of
3:09
the program is running so if I want to
3:11
keep it in continuous you know running
3:14
state whenever my system is either
3:15
restarted or didn't shut down state I
3:18
can also check into this and then again
3:21
I can see - it said unit or I can make
3:25
it work so for that we also have
3:27
multiple tools so we can check for the
3:29
performance of this particular resources
3:32
so those particular resources have
3:34
multiple tools which handy even diagnose
3:37
what exactly is happening into the
3:38
prunus particular resources and how we
3:40
can utilize the rest amount of resources
3:42
for that the tools we'll be using that
3:44
is your nice-nice is just basically your
3:47
command which is inbuilt into all
3:49
distros of your Linux operating system
3:51
so nice you can check for the commands
3:54
or the processes which are going on what
3:56
are the priorities they're getting so
3:58
you will be able to see it as well as
4:00
you can also modify this nice value or
4:02
called as a priority of the task by
4:04
giving the really nice command same way
4:08
we have net state if I want to check or
4:10
print what is the status of my network
4:13
so all the particular stages all the
4:15
predict you'll net work protocols which
4:17
are running and back-end can also be
4:18
checked by using the net state command
4:21
then we have time so time give you the
4:24
resource timing of the
4:26
Wise's which are using into the system
4:29
then uptime what does the average time
4:33
your system is up then PS command it
4:37
will show you the processes which are
4:38
running so right now if I want to check
4:40
what are the processes which are running
4:41
I can get the list of processes by
4:43
giving the command called SPS VM State
4:46
again we can get the virtual memory
4:48
statics into it G proof command we can
4:51
use if I want the profile data or we can
4:54
say a Linux performance data into a
4:57
graphical portal program cycle profile
4:59
we can use the G proof then we have
5:02
proof so you can create a profile
5:05
profiling or we can say a graphical
5:07
profiling by using the proofs then we
5:10
have top top command we can use so that
5:13
we can also get the current running
5:16
tasks and you know this particular top
5:18
command will give you the live status of
5:20
the different processes once you run the
5:22
talk it doesn't get end it directly will
5:24
show you our display of all the
5:26
processes running and the priorities of
5:28
this process and the resources which you
5:30
are using so automatically you will see
5:32
into the Camaro's itself or when you get
5:34
the output itself it will be changing
5:36
its value as it shows you the live
5:39
process and it changes as per your going
5:42
to use this particular command so then
5:45
we are going to see how we are going to
5:46
use this Linux into the next video and
5:49
how you are going to check for the
5:50
performance or the device Diagnostics by
5:53
using the resource monitoring tool into
5:55
