Technical Monitoring High Disk I/O

We are looking at the Average Wait Time per Disk metric (Under host, windows) as it pertains to our MS SQL server.
The situation is that this server has multiple "disks" - some for data, the standard c:\ drive (OS). These disks would have different thresholds which would be appropriate to trigger alerts.
The problem is that the threshold appears to be "global". Meaning if any one of the disks satisfies the threshold, we get the alert.
We did look at the data collection tab for this metric. We were hoping we could add different disks (as variants?) and then assign thresholds at to each.
Unfortunately, This metric doesn't seem to support variants. There is only on parameter - Disk Name, with the default value of *
Is there any way to establish this metric for different "disks"?
Any help would be very much appreciated.
thanks,
Jeff Henke

Hi Jeff,
This metric is actually metric group, means its supports the variant, But the variant doesnt have the parameter for threshold. Ofcourse, It shouldnt have. Luckily it has disk name parameter, then you can do it for each disk.
For your scenario, You must create custom metric for each disk, by adding the disk name in the diskname parameter and set the threshold. since you have separate metric for each disk, it works as you expected.
Thanks

KDE 4.7: very slow and high disk usage

Since upgrade to KDE 4.7 on my i686 laptop, my system behaves weirdly. I noticed a slow down caused by a very high disk usage: when the HDD spins the cpu usage reported by the CPU monitor plasmoid is very high (~ 50%), while top reports a very small CPU load. Another strange symptom is that, when I try to close the session, the system freezes for about 15 seconds before the logout/shutdown/restart dialog window appears, again with HDD spinning furiously. If I exit the dialog window and then try to close session again it works smoothly, so I think some caching is at work at second try.
This is very painful since it slows down my workflow. Since now I tried to:
- disable nepomuk, strigi and all that using the nepomukcontroller plasmoid
- disable compositing
- delete .kde folder
- uninstall and reinstall all kde packages
without any benefit. On the same laptop I have dual boot with a 64 bit arch installation, which does not have the same problem, nor has it my 64 bit desktop pc.
Does anyone have similar issues? I don't understand what is it that makes the HDD spin so much, nor how to eventually track it down (are there som HDD usage profiling utilities?). Moreover, why top and CPU usage plasmoid report so different CPU usage stats?
I'm very confused, so any help will be greatly appreciated.

Although I'm not having any of the issues as Snack, I have found KDE 4.7.0 to be a very horrible release. In fact, I'm sick and tired of the KDE release notes bragging about killing thousands of bugs each release, when in actuality the first few revisions of each stable release are horrible. When I first upgraded, I ran into at least four really nasty bugs. Although I've worked around some of them, it left a really sour taste in my mouth. Here is what I've experienced:
1.) With a new user or fresh install, there is no wallpaper by default, even if I install kde-wallpapers before I log in, it makes no difference.
2.) Sometimes kwin will crash during log out.
3.) Worse yet, if I exit a full screen game, it will more than likely crash Kwin. This is a problem on my laptop (which has intel video) and not my desktop (which has nvidia video). If I don't remember to disable desktop effects before opening a game, I may run into a problem.
4.) Although my performance is good, it's not great. I would think a laptop with a Core i5 processor and 8GB of RAM would run faster than it is.
I have tested XFCE for a bit, and I do like it alot. However, with XFCE I am unable to browse Samba shares, and that is a huge problem. In addition, I find KDE's applications to be much better than what ships with XFCE, but I question whether they're worth the performance hit. I really love Kate, Gwenview, Digikam, and Amarok. I know you can install those in XFCE, but they feel out of place and then my desktop pretty much becomes a mutt. Not only that, but KDE is full featured, whereas XFCE is not. It's like I have to choose between a stable desktop or a desktop with full of bugs.
I hope that KDE 4.7.1 fixes everything, but historically it's usually the 4.x.2 release that really does the trick.

High disk utilization every 24 hours

Hi all,
While troubleshooting an user's complain about slow access to his mailbox on a Windows 2012/Exchange 2013 environment, I came across this interesting behavior:
Disk utilization on the server will increase from 100KBps to 3000KBps (on average) and stay high for a good 10 hours or so. Then disk activity will go down for exactly 24 hours from the time it was up and increase again for another cycle.
Basically, no matter how long it takes to go down, it will increase again 24 hours later. Looking at Perfmon and Resource Manager all I could see during both periods is that store.worker.exe is always on top, and READ has higher values. The issue does not
appear to be related to business hours / backup window / client access to exchange, as it occurs at different times of the day and changes everyday.
I believe it has something to do with an internal maintenance/reporting/monitoring feature of Exchange 2013, as it happens on 3 Exchange environments we manage, completely apart from each other.
Microsoft Exchange Health Manager service has already been disabled as well as scheduled tasks under Microsoft/Windows/PLA and they all proved not to make a difference.
Any ideas out there?

Good Call. I just spent the last few hours going over 550,000 events.
I reviewed the application log for a 24 hour period and here is what I noticed:
During the high disk queue period there are lots of entries for MsExchangeMailboxAssistants. For each of the 15 mailbox databases.
These only run during the High Disk Queues window.

Here are the examples of the log entries for Event ID 9017

It appears the purge of orphaned mailboxes happens only at this time as well .
These run throughout the day and not just 24 hours after the last restart/switchover.

So how do I get the first group of maintenance tasks to run throughout the day, or at different times, or at least not all at the same time for all 15 databases?
Thanks!!
Well, its all workload based, so I don't think you can readily adjust that.
I'm more inclined to look at the specs of the mailbox servers. Are they up to the task and have they been vetted with the Mailbox Calculator?

Technical Monitoring - Metric Sybase Performance

Hi experts,
are there any performance-metrics in technical monitoring for database "Sybase"?
I found metrics like physical reads and writes or logical.
But they are only for temp-db usage.
So I think not really relevant for performance, or are the relevant?
I am not really sure what it means.
What I am looking for is like, how many reads/writes per seconds and what was the average time for <SID>-DB.
Also I don't get any results for Disk Reads/Writes per Seconds.
Kind regards

Hello Giri,
I had a discussion with this about SAP.
And no, it is not possible to create customer metrics regarding ASE-performance.
All ASE-performance metrics get calculated within ST-PI coding and are hardcoded.
So there is no kind of "extractor" like CCMS which can be used.
Sure, it would be possible to code your own performance-calculation, but therefore you need to access the ASE-data, which I don't know how to realize.
However, in SP12 a lot of new ASE-performance metrics will be delivered.
So looking forward.

Low number users, high disk IO, 11g 106 Win32

I can see for a high number of users in a critical high availability environment,
all the things Oracle does for maintenance, monitoring, etc. is vital.
But for an intranet office with 5 users and less than 4 gigs of data, using the database in the daytime only, and a couple backup jobs running at night, is there a way to reduce the frequency of oracle disk IO events for monitoring, etc. The hard drives are just running themselves to death.
Oracle CPU use is low after fixing a known problem with Windows 11g 106 and one maintenance job problem noted on this forum previously related to sysman.mgmt_job where job_name = 'PROVISIONING DAEMON'.
It is possible part of the high disk IO is Windows 2008 adding many behind the scenes monitoring tasks compared to Windows 2003.
Any ideas to reduce disk thrashing in low user environment would be welcome.
Thanks

High disk usage/high memory usage.

i keep getting high memory usage and high disk usage in ps cs6.
its slow when i open a file. how can i solve this problem.
thank you.
philip.

Not to put too fine a point on it, but more than what? More RAM is almost always better, but you haven't answered most of the questions posed here. The answer might be different if you have 2 GB of RAM or 32 GB of RAM already. A 9 megapixel document could get rather large with a lot of layers, but again you've neglected to give any hard info about its size.
Regarding your video card, that's a bit of a judgment call you need to make. For Photoshop CS6 I currently advise people to try to get a video card that gets a score of 1000 or better on this benchmark: http://www.videocardbenchmark.net/high_end_gpus.html
Video card speed will matter when you're editing those 3D components and video card VRAM will also matter, but possibly even more importantly your GeForce 320 is a bit old, and nVidia may just not be doing their best driver work for it any more.
Everything in general will run more smoothly with a powerful modern video card. I like to recommend a VisionTek ATI Radeon HD 7750 - or if the computer power supply and your budget allow, the even more powerful 7850. VisionTek does a very good job with their hardware, IMO, and it comes with a lifetime guarantee.
Keep in mind that if you switch from nVidia to ATI or vice versa, you should carefully sweep your system to ensure all files from the old card are removed, then visit the web site of the new card's maker and download/install their latest display driver release.
Best of luck.

RAM Issues + High disk usage on MSI GE60

Recently I've noticed that my system slowly eats up RAM. It starts off at 21% and can go as high up as 80% or more. When I'm playing games on it the RAM does not clear up properly either, it stays at 50% or so. This was an issue before that I somehow managed to solve, but it is back again.
As for high disk usage, that's been a problem since I've had the laptop.
OS: Windows 8
Processor: Intel Core i7 4700MQ (2.40GHz)
GPU: NVIDIA GeForce GTX 765M
RAM: 8GB Memory
HDD: 750GB
If you need more info I'll provide it.

If you open task manager-> performance -> open resource manager / you will see whats eating up your resources
if its windows see if indexing is off
did you installed 3rd party software diffrent than stock ?
how old is your laptop?
its not normal to have such high usage numbers !! i think its a program causing the problems !
if you check your resource manager you will be able to see whats causing it
ps if possible please post a screen shot and ill look into it

[SOLVED] High disk activity after kernel boot

Hi,
after kernel loading (just before getty starts) i notice extremely high disk activity for ~20 seconds for no reason. I think that it is something related to systemd and mount services.
When i set rootfs to read-only in syslinux kernel parameters then the system starts normally without delay. So, i think that something is constantly writing to (or checking?) my hard disk right after boot sequence.
I'm using kernel 3.7.9-1-ARCH.

It was a problem with preload and its configuration.. I removed it and everything went back to normal!

Where do I set the polling frequency for Technical monitoring in Solution Manager 7.1 SP10 ??

Hi All,
I am customizing my technical monitoring templates and would like to know :
1. Where we can set the polling frequency for each metrics for triggering alerts through Technical monitoring in Solution Manager 7.1 SP10 ??
2. Is it like each time our threshold is breached, it will send an alert irrespective of polling frequency ??
I know the data collection interval time for each metrics in technical monitoring template but the as per my observation the polling frequency is different.
Need your guidance.

Hi Javier,
Refer to the documentation 'MAI Alert Consumer BAdI Interface' under
http://wiki.scn.sap.com/wiki/display/TechOps/Alert+Consumer+BAdI+Interface link for information on the input to the BAdI.

Check process generating high disk I/O read

Hi Gurus,
In Solaris 8, which command can I use to check the process that is generating high disk IO read ?
Mav

I do not know which file is generating high disk IO read.
Is there a command to check which process is generating more Disk IO read ?
I'm using iostat to check Disk IO read every 15 minutes and output to a log file. But I'm unable to determine
which process is causing high Disk IO read at times.

Technical Monitoring - Mail: Acknowledge/OK

Hello experts,
I have three questions about mail notification in solution manager technical monitoring.
1. Acknowledge
Also when I postpone an alert in technical monitoring (maybe 1 week back) I receive an email about the problem.
Is this a bug?
2. OK/Acknowledge-Mail
Is there a possibilty to receive also an email, when the status is changed to "Acknwoledge/postponed" or to green-status (=OK)?
Kind regards

Hello Roland,
yes, but this does not make sense.
Because, I also hid the alert because I am already informed about the issue.
And so I don't want to get spamed with 100s of mails.
And I also would like to acknowledge my colleagues, that already one guy is working no problem.
Especially durring night-shifts.
Kind regards

Technical Monitoring for Logical host name

Dear experts,
We are in mid of technical monitoring finalisation.
one of the interesting thing which i found with respect to the logical host name, we installed SMD agent on Virtual host name and our system is not with HA environment and no clustering. It is just a system with single instance.
During the managed system configuration all the physical and logical host name reported by SMD autodiscovery, all went fine. But in Technical monitoring shows only virtual host name with the updated alerts , and logical host name only shows grey alert.
virtual host shows alert here
logical host name shows grey
how can i get alert displayed for logical host name too? do i need to do some settings at the OS level , could you guide us?
Thanks
Jansi

Hi Giri Raju Ayyagari,
I am sorry, seems you are still not able to get my issue, moreover you get diverting my issue
Here the problem is not at all related to agents on fly. thats the separate topic.
We are having issue on Logical Host names where there is no HA environment, means only One logical host name created.
I raised to SAP, l will update once the update from SAP given.
Best regards
Jansi

XML Query Have High Disk Reads.

Question regarding XML data. When I query the following sql statement, the performance is fast. In addition, the explain plan shows that this query is efficient and utliizing all the indexes. However, when I query the v$sql table, I see that this query has very high physical read. Any idea as to why this query has a high physical read?
SELECT lpcs.TEXT_LOAN_PCH_CONT_CNTNT_XML.extract('/').getClobVal() as TEXT_CNTNT_XML
FROM REFTDBR1.LOAN_PCH_CONT_CNTNT_SET lpcs
WHERE lpcs.ID_LOAN_PCH_CONT = '9c24ede6-2bf0-4a9c-8345-fa986ec7516c'

AND lpcs.ind_curr = 'Y'

We're on Oracle 11Rg1 RAC with ASM architecture on Liinux platform. Below is the explain plan

This query was executed 1623 times so I guess that could explain the high disk reads? Does this mean that this query is not being stored in the buffer cache since the disk reads are high?

Technical Monitoring - DBA Connection red (failure)

Hi experts,
I have the following problem.
In technical monitoring I have one managed system, on which the DB availability check is not working.
The DB is a Sybase ASE 15.7
In solman_setup->system config the DB connection is configured well (green status).
Also if I open the dbacockpit of solution manager, I can see the DB of the managed system and the connection checks are working fine.
But in technical monitoring, I get the alert that the DB is not available and also that "DBA Cokcpit Connection Status" = failure.
If I go to the details of the alert, I also can't see the problem.
I did already remove and add the system more often. Further I also did remove the connection in dbacockcpit and created it again.
But now I don't have any further ideas.
Hopefuly somebody can help me.
Thank you
