No or Low Overhead Performance Monitoring

Reading V$ or X$ tables for performance monitoring generates very high overhead on Database. These tables are nothing but dymamic views over SGA. Is there any way or any API available to read directly from SGA.
Thanks & Regards
Rajesh

Really I have never heard anything alike before but
perhaps with this document you can find something
about it.

OEM overhead in performance monitoring

Is it necessary to use OEM Grid Control, not the local Database Control, to avoid the overhead of monitoring? Should I install OEM Grid on another server to monitor the performance of I/O, CPU, and other indicators on my database server?

830252 wrote:
I hoped for the answer that the Grid Control is not necessary. I have only one database instance to monitor and the Grid Control requires several pieces to be installed, agents, WebLogic server and a database for the repository, plus some patches. This seems to be a bigger project in itselft. There is a long list of requirements and pre-requisites. The monitoring that I need to do is actually very limited in scope. I have only parts of the applications to monitor at the performance testing time. This is not a system in production.The basic functionality for monitoring and administering a single database is pretty much the same. What Grid Control brings to the table is a single portal for administering multiple databases. If you only have one db, Grid would be overkill for no additional benefit.
And contrary to what some think, you can use dbcontrol when handling multiple databases, but each db will have to have its own instance of dbcontrol, and if they are on the same host, they will each need to be configured with its own port, and thus will be accessed with its own url.

BEA 81. Application Performance Monitoring Tool

Is there a good reasonably priced performance tool that can be integrated with
bea 8.1 or even work independently which can monitor ejb, servlets, jsp's, jdbc,
portlets, portals etc. We tried jprobe but that does not seem to work well at
all.
We have several applications in 8.1 and want to be able to test where the performance
issues are.
Thanks

You should try Performasure from the same company that makes Jprobe. Its a great
tool that can do weblogic clusters with low overhead.

Performance monitor reports and graphs don't show all the counters that were captured

I've run into an odd behavior of performance monitor that I haven't been able to clear up yet: after I run a data collector set, the resulting report only shows a partial list of the counters that I captured, and so does the graph of that report (but different
items).
For instance, I chose the following counters for the data collector set:
\PhysicalDisk(*)\% Idle Time
\PhysicalDisk(*)\Avg. Disk Queue Length
\PhysicalDisk(*)\Avg. Disk sec/Read
\PhysicalDisk(*)\Avg. Disk sec/Write
When the data collection ends, the report that gets displayed shows all those counters for _Total instance and C:, but then E: only shows % Idle Time and Avg. Disk Queue Length. That's it, the report ends there, even though I also have F: and V: drives on
this server.
If I choose to view the graph of this data collection, it only shows those four counters for the _Total instance.
It took me a while to realize that all the data is being captured, but it's just the display that is truncated. If I view the folder then open the report.html, it actually shows all the data. Same with the graphs. If I select to add counters and add
all the missing counters, they are displayed.
I have searched high and low but haven't been able to find more than one post at ServerFault where someone had a similar issue, but no real solution or cause was provided, so I was hoping that someone here might have an idea.
I also found a variety of articles about missing counters due to registry settings or because the counters needed to be reset, but that's a different issue that doesn't apply in my case. By the way, this is on a windows server 2012 R2 VM (file server).

Hi SomeAdmin,
The counter missing often caused by the related registry value is corrupted, please first refer the following related KB then perform a fix then monitor the issue again.

Standard value for performance monitoring

Guys,
I am looking into performance monitoring in the RWB bacause I think our production server is too slow. I get an average processing time per message around 60 sec, +/- 30 sec depending on the volume going through. This is obviously an unexceptable value...
But I was wondering, are there standards set for these values to indicate when performance is too (s)low? Any reference docs available from SAP?
Thanks

There are various factors need to be considered. 60 seconds happening for almost all interfaces or only some specific. If only for some interfaces, then check the message volume size. SAP recommends message size up to 5 mb for optimum performance. Also security layers such as https/ssl and message level security such as encryption or digital signing/verify could cause some additional delay in processing too.
Fixing Hardware is easy... You go for the SAP recommended spec.
If you are using PI 7.1 or above use Message Packaging configuration. This will help considerable boost in performance.

Need Help! CPU shows 100% constantly in performance monitor

We have a new Dell t620 server running server 2012 std. running AD DS, dhcp, dns and the performance monitor shows constant 100% CPU load, while the processes in task manager can show very little CPU useage. By the way this is a Intel Xeon E5-2620 6 core
CPU, with 32GB ram which shows normally using only about 2GB ram at the same time. If I do a shutdown and restart I am getting the same 100% CPU load.
Does anyone know what might be causing this behavior?
We have other identical servers which show usually zero to low CPU load, performing the same functions.
Is this a known problem with server 2012 std.?

This server is now in service on a network. So I cannot shut it down during business day.
What is really strange is when I open task manager it shows almost all the CPU useage in APPS, which consist of task manager and resource monitor, with task manager sometimes even going to 100% CPU useage.
While memory, harddisk and ethernet are showing like low useage.
Do you all think it could be memory or a bad CPU? This is a 1 week old Dell server.
Does anyone know if there is a good memory checker that can be run from windows while server is in service?
Thank you for your assistance.

How to genarate performance monitoring report in SAP PI automatically

Dear All,
I have a requirement where I need to automatically generate a report of monthly data of Performance monitoring in SAP PI and send it to business users.
As per my understanding, this can be achieved by pulling the data every month from the tables where these data of Performance monitoring is maintained internally within SAP PI.
Please provide me inputs as which table stores these data/ and solutions to acheive this.
Thanks
Azahar

Refer below links .. You can write abap report to make it happen

In order to find the PerformanceMonitor web app, the ConsoleExt needs to
examine your classpath to get the appropriate WLHOME. It does this by
searching for .../server/lib/weblogic.jar. Please make sure your CLASSPATH
is correct and matches where PerformanceMonitor is installed. For example,
the path to .../server/lib/weblogic.jar is the same as to ../common/perf. In
my world, they both happen to be d:\bea\weblogic81.

How do I write/use performance monitor to run an action when something happens?

I notice that I get a popup if desktop resources are over-used asking me if I want to turn off the glass desktop.
That's fine.
I've been looking in Performance Monitor for how this is done, as I have a program that periodically runs amok and starts indexing my Documents directory. I usually start to notice my machine getting sluggish when the process gets to about 1.5-2+GB
in Virtual and working memory. At that point it seems to be increasing it's network usage rate geometically, and interrups will start getting delayed or lost -- keyboard will lock up for periods, lots of things freezing temporarily (music will get 10-20
second dropouts) It can even cause a complete system lockup
So what I would like to do is monitor any instance of this process by name ('explorer'), and restart it when it gets to over 1.5GB of usage.
I setup a monitor of virtual size and working memory in the performance monitor, but I don't see how to set up an alarm that starts an action to restart it. (restarting it will cause the problem to go away for anywhere from a few hours to several days).
I've no clue as to what triggers it.
I found a bunch of XML scripts in
Windows/pla/Rules with names like:
Rules.System.CPU.xml*
Rules.System.Common.xml*
Rules.System.Configuration.xml*
Rules.System.Diagnostics.xml*
Rules.System.Disk.xml*
Rules.System.Finale.xml*
Rules.System.Memory.xml*
Rules.System.NetDiagFramework.xml*
Rules.System.NetTrace.xml*
Rules.System.Network.xml*
Rules.System.Performance.xml*
Rules.System.Performance.xml.orig*
Rules.System.Summary.xml*
Rules.System.Wired.xml*
Rules.System.Wireless.xml*
These have some XML language in them that looks like it woud be for monitorying and doing actions:
<Rule name="$(RuleDiskSummary)" enabled="true">
   <Step select="/Report/Section/Table[@name='hotFile']">
    <Exists>
     <Otherwise>
      <Delete select="Summary"/>

Question is, how can I setup it for calling a trigger script when
parameters for Explorer get out of spec.
On confusing issue that stopped me from proceeding, was the time schedule to run the report:
I only allows for once/day.
I need / want continuous monitorying -- say at 1 minute or 3 minute intervals (5 might work, not sure -- doesn't take long for Explorer to get to 1-2G with a network connection of 10Gb.
So how can I monitor and control it?
A side issue -- I notice a resource-control agent for Win 2008 -- but this was disabled for Win7.
Anyone know why resource usage on Win7 was considered less important than on Win2k8 server?
My version of Win7 is Win7-x64-sp1 "Ultimate" [sic] (it doesn't include professional features like resource control)...
Thanks...This has bothered me for over a year and has persisted through new profiles and reinstalls of of the OS.
I have a feeling it is related to MS disabling Network disks in their indexer, so Explorer ends up doing it as a surrogage for things like the search engine (with the results not stored, because they are not local -- the worst of both worlds?)... but that's
just a feeling...
Thanks!
Astara...

You can create a Data Collector Set (create manually, not template), then choose performance counter Alert, configure alert actions, from the script, seems you want to monitor the “physicalDisk” performance, so you can set the “physicalDiskCounters”
into alert action, please follow the instruction in the link below.
Monitor disk space

If you want to view the detailed process related about explorer when your machine getting sluggish, I'd like to introduce a tool named process explorer to you.
http://technet.microsoft.com/en-in/sysinternals/bb896653.aspx
It can clearly show you the processes running in your system, along with the hierarchical relationship and the cpu usage.

Regarding performance monitoring of RWB

As far as I know , there are two ways to show the data through performance monitoring.One is [overview data],the other is [detailed data].My question is,my [overview data] is displayed successfully,but [detailed data] doesn't display anything.Some parameter need to set for [detailed data]?
Any help would be appreciated.
Brand.

Hi Brand,
If detailed data is missing i think some settings were missed & just go thru the links given below ur problem will be solved
Can you check the following function modules. In SE37 look for FMs "SXIPERF*" . You will get
SXIPERF_RUNTIME XI Performance: Runtime
SXIPERF_RUNTIME_VERI XI Performance: Runtime
SXIPERF_CONFIG XI Performance: Configuration
SXIPERF_EVALUATE XI Performance: Evaluation
