Server :: Peak Bandwidth Compared To Max ?
Dec 29, 2010I have a server in a data centre, which is supposed to have a 100Mbit line. Peak rates at the moment on my server are in the region of 20Mb, which should be easily handled. Is there anyway I can trace how much more bandwidth is available at any one time or if things are becoming sluggish on the server?

View 2 Replies View RelatedSUSE :: Drive Access At 100% Utilization?
Nov 9, 2010I 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.
CentOS 5 :: High CPU Utilization For All Processes?
Apr 9, 2010I 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.

Nov 11, 2009I 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

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

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.

View 1 Replies View RelatedServer :: Memory Peak Caused Server Crash - Data Interpretation?
Dec 16, 2010Last week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.

Red Hat / Fedora :: Unable To Push RHEL 6.0 Past 95% Utilization
Apr 22, 2011- 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.

Jul 6, 2010So I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:
[Code]...
Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.

I would like to use sed or similar to remove everything before the period, but only for the lines 1 and 3 (or lines with a-z.a-z and not a-z = 0-9.0-9.0-9.0-9)
I found a way to do this using:
cat $file | sed 's/[.].*//'
But this 1)remove all the text AFTER the period and not before it, and 2) removes everything after the first decimal of the IP address.
