A) I am not sure why the cache memory is not released ?
B) Even when utilization in Top is going to 32 GB i.e. when Informatica jobs are running, Cache is still at 18GB ... Shouldn't cache be released because Informatica jobs are hanging ?
I strongly feel this is nothing to do with Server memory because I see swap memory not come into play at all but before I go to Informatica and raise a flag... I want to make sure there is nothing from server side... what more can I do to ensure that everything on server side works fine i.e. CPU & IO or Network, as I am not able to think of any other factor affecting this from server side?
Hi,
would like to know the server status from the following 'top' out put. Because, the application is giving a bad performance. would like to know whether the load is within the acceptable limit.

Hi All,
I would like to create a script that will monitor the server if it's heavy on the processing. I have already some scripts for monitoring disk capacity, application monitoring, etc but not on the bottleneck of the server processing.
I don't know which one to measure/query.
Can you... (2 Replies)
Ello group,
I have general question about how the performance of server/client should be?
My server is able to answer about 650times per second. Is it good performance?
the apache on the same machine makes 1600/sec BUT there is nine instances of httpd daemon what makes 180/ sec /instance.

Hi,
I am supposed to run few jobs based on the usage of unix server. How to find out if the server is too busy. what are the commands we can use to find out that.

Hi,
i would like to ask if it is possible to get the server load on a solaris machine, but i don't want something like uptime (load average), iostat and vmstat. I would like to get something in percentage like CPU load in %, Disk usage in %, Ram usage in %.
I want to collect this data and to... (3 Replies)
There is a big problem with the server (VPS based on OpenVZ, CentOS 5, 3GB RAM). The problem is the following. The first 15-20 minutes after starting the server is operating normally, the load average is less than or about 1.0, but then begins to increase sharply% wa, then hovers around 95-99%.... (2 Replies)

Hi,
how can we define performance of a server (Windows or Unix or Linux) ?
If processes waiting for CPU (on queue) are usually more than 3 or 5 can we conclude that CPU is not enough for that usage ?
Thank you. (1 Reply)
Hi Guys,
I am running Oracle database on RHEL 2.6.18-164.el5, now I want to check and make sure that my server is performing optimally.

xsysinfo
XSYSINFO(1x) Debian GNU/Linux XSYSINFO(1x)NAME
xsysinfo - Display Linux kernel parameters in graphical form
SYNOPSIS
xsysinfo [-help] [-update n] [-[no]title] [-[no]labels] [-[no]loadavg] [-[no]load] [-[no]mem] [-[no]swap] [-[no]smp]
DESCRIPTION
Xsysinfo is an X application to display some Linux kernel parameters in graphical form. It is like a mix of top, free and xload with the
difference that the values are shown in form of a horizontal bar. The displayed values are: CPU load average, CPU load, memory and swap
sizes (details see below).
OPTIONS -update n
Set update rate to n milli-seconds
-title Show title string
-notitle
Don't show title string
-labels
Show gauge labels
-nolabels
Don't show gauge labels
-loadavg
Show CPU load average value
-noloadavg
Don't show CPU load average value
-load Show CPU load value
-noload
Don't show CPU load value
-smp Show separate SMP loads
-nosmp Don't show separate SMP loads.
-mem Show memory info
-nomem Don't show memory info
-swap Show swap info
-noswap
Don't show swap info
-help Display options
DISPLAY
Xsysinfo display the following values:
CPU load average
CPU load average between 0.000-8.000. The gauge's bar is subdivided into segments, where one segment represents a load value of 1.0.
The bar's full length is automatically scaled, depending on the displayed value.
CPU load
percentage CPU load time to CPU idle time subdivided in three segments: user load, system load and nice load. On an SMP system the
-smp option replaces the single total load meter with a separate meter for each processor.
Memory The memory gauge's bar is subdivided into two segments with the amount of physical memory, which is used by processes on the left
and physical memory used for the page and buffer cache on the right. The length of the whole bar, which is the sum of these two val-
ues, shows the amount of physical memory currently used by the system.
Swap The percentage of swap space used by the system to total amount of swap space.
