We are wondering if we are facing performance issue in our server when running Informatica jobs. Two things to suspect:
cache memory never comes down even when Top shows > 99% used.
There is some contention io or network related or Cache is clogged
If We kill all Informatica services & jobs... the utilization in Top comes down to
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 all,
My server box is slow running. I have provide some statistics below:

I guess the bottleneck is disk I/O?

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.
I check top:

pmgrd(8) System Manager's Manual pmgrd(8)NAME
pmgrd - The Performance Manager metrics server daemon
SYNOPSIS
/usr/sbin/pmgrd
DESCRIPTION
The Performance Manager (PM) metrics server (pmgrd) is a UNIX daemon process that provides general UNIX performance metrics on request.
The pmgrd metrics server supports the extensible SNMP agent mechanism (eSNMP). The pmgrd metrics server is a subagent that runs by default
whenever the SNMP agent is started.
The pmgrd metrics server also listens for SNMP requests on a private UDP port. The private port accepts SNMPv1 requests, and supports the
SNMPv2 GET-BULK request for efficient bulk data transfer (using noAuth/noPriv security). The pmgr and getbulk programs require this capa-
bility.
The MIB (management information base) variables implemented by the pmgrd metrics server are described at this location: /usr/share/sys-
man/mibs/pm.mib.
The getone, getmany, getbulk, and gettab UNIX commands issue SNMP requests. You can use these commands to communicate directly with the
pmgrd metrics server if you set the environment variable PMGR_SNMP_PORT.
FILES
The metrics server daemon. The MIB file for the pmgrd daemon. messages generated by the pmgrd are logged to this file.
SEE ALSO
Commands: getone(1), getmany(1), getbulk(1), and gettab(1).
