I have a SSH access to some linux servers, is it possible that I can get some graphical report for system utilization (CPU, memory and disk space) for a given time range.
I dont have any graphical access to the system.
Currently I am fetching the records using "sar -r" command , pasting them in a excel sheet to generate the reports.
When the memory usage reaches 95% and above I noticed that the disk activity and load graphs go up and some of my applications are killed by the system. In windows, if someone define a pagefile then the OS will try to use it at the expense of very slow response. Why ubuntu does not use SWAP in such a way?
View 12 Replies View RelatedI have a server running samba process and there are about 70 samba users connected at a time. The system has 4Gb of memory and it seems each samba process is utilizing only 3352Kb of memory.
When I run the command
pmap -d (pid of samba)
It gives as:
b7ffa000 4 rw-s- 0000000000000000 0fd:00003 messages.tdb
bfe46000 1768 rw--- 00000000bfe46000 000:00000 [ stack ]
ffffe000 4 r-x-- 0000000000000000 000:00000 [ anon ]
mapped: 33384K writeable/private: 3352K shared: 20504K
But when I run the top command, it results as below:
Tasks: 163 total, 1 running, 162 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.9% us, 4.9% sy, 0.0% ni, 93.3% id, 0.8% wa, 0.2% hi, 0.0% si
Mem: 3895444k total, 3163192k used, 732252k free, 352344k buffers
Swap: 2097144k total, 208k used, 2096936k free, 2487636k cached
Why could the system be utilizing such high memory? By the way, the server is not running other processes. The samba version running in it is 3.0.33-0.17.
As we know, the data in /proc/net/dev fall into two categories -- the data received and the data transmitted. Now I want to calculate the network utilization, should the calculate be ---- (datareceived + datatransmitted - datareceivedlasttime - data transmitted last time)/ timeinterval?
View 1 Replies View RelatedI am trying to develop a video resource manager in Linux.By that what I mean is, if two applications (may be running in two different machines) are trying to play videos, the video resources will be served by this video resource manager (running at a center location). Pardon me as I donot have much idea about video resource handling in Linux , first of all , it is feasible to have this kind of a layer, in between the applications and the available resource hardware.
Kindly give me some pointer as to how do I start? Pl. give me some reference URLs.
I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?

View 1 Replies View RelatedI have to write lab reports with charts and graphs on a regular basis. i did the first one in open office recently but the charts did not appear on my teachers screen! it was a broken failed half rendered blank chart area!
The data tables copied fine but the graphs did not. i made both in spreadsheet and copy pasted them over to a writer document.
how graphs can be plotted on a web interface on real time ? I have a web interface coded in PHP mostly and for graphs I have jpgraphs. But the job needs the graphs to be real time not static. As of now there's a server side program that writes onto a csv file. I read data from the file and plot it using jpgraph when the page loads. Is there anyway I can code real-time dynamic graphs on a web interface ?

how to get all CPU utilization in using top command
I was trying to do some graphing of the Disk Usage of the my root partition.
I tried it with rrdtool,but I am not able to create any graph.
I followed the below steps
1. Creating a rrd database file
rrdtool create diskusage.rrd --start N DS:Usage:ABSOLUTE:600:1:100 RRA:AVERAGE:0.5:1:432
I then updated the rrd file with below cron entry code...
Why no data is coming into the rrd file ?
I have a Ubuntu 10.04 LTS and about 40 ThinClients running LSTP in a school's computer lab. Everytime the users start to use applications, the server's memory utilization increases, while the swap memory is quite free. I have 12GB of memory on that server.

View 2 Replies View RelatedI have a storage array and one of the logical volumes stays at 100% utilization whenever any process accesses the volume. It is a 9TB RAID 5 array on it's own SCSI interface card. I have another 9TB logical volume in the same chassis, on it's own card that does NOT exhibit the same behavior.
I'm measuring the utilization using atop. The strange thing is it pegs out at 100% utilization for the entire time a process accesses the volume, even when the data being accessed is just a few kb. My users home directories reside on this volume so as you can imagine every user is impacted whenever someone accesses any file from this volume.
The only processes being shown in atop are nfsd processes and xfslogd process. Nothing has been deliberately changed on this system. The only thing out of the ordinary that changed is a user deleted several TB from his home directory a week or so ago, just about the same time this problem came up. During the troubleshooting process, tis system has been rebooted several times.
I am getting a strange problem with my new machine (P4 3Ghz, 1 GB RAM DDR333). The machine is an industrial PC. Firstly I had installed Fedora Core 2 on it. It ran superbly without any problem. I tried to load Redhat Enterprise Linux WS4 (Update 2 as well as Update 5) on it. But the PC was giving high CPU utilization for each and every task. With-out any application running both the cores shows utilization around 10 %. But when i try to my application, the CPU utilization in one of the cores goes to 100 % for majority of the time. This is causing my appilcation to run slowly when compared to the same application running on the same machine under fedora core 2. (CPU Utilization around peak 17 % in either of the cores in Fedora Core2) Recently I installed Cent OS 5 on it. But the behavior of the PC remains the same as of Redhat Enterprise Linux WS4. Some-where on the forums I had read about the RAM size. So i tried to downgrade the RAM from 1 GB to 256 MB. But the problem remains the same. I think it has to do with some kernel tweaking.

View 5 Replies View Related- I am running with Oracle UEL 6.0 (2.6.32-100.28.5.el6) because stock RHEL 6.0 (2.6.32-71.el6 ) has issues with the async I/O driver.
- The test is a high throughput performance benchmark running on Oracle 11gR1
- I am pumping a lot of disk I/O through the system while running with enough users to max out the 8 CPUs, which get to 99+% utilization with RHEL 5.3
- The server is a 4-socket Nehalem EX X7560. Right now, only 2 cores per socket are enabled.
- There are GBs of memory left over. The disk response time of the SSD arrays is around 1ms and the arrays are capable of 4-5 times more IOPS. Same with networking, etc. The testbed is capable of maxing out 32 CPUs with RHEL 5.3 I cannot push the RHEL 6.0 CPU utilization past 95-96%. The same test on all flavors of RHEL from 4.4 to 5.3 can totally saturate the CPUs. It feels like the system is intentionally holding back some CPU cycles.
is there any performance tool for linux? i av found phoronix but it cant provide testing on memory, CPU, hard disk utilization and also stress test.
