Setting thresholds for cpu governor with TLP?

I used to have a set of scripts with every power saving trick I ever collected that would run upon un/plugging my laptop. But today I decided to play with TLP because it's all the rage these days.
It's really nice! It seems to hit more stuff than Laptop Mode Tools did, which is awesome. My powertop is reporting under 11 watts, which is about as good as I can ever get with this laptop.
The one thing I'm missing, though, is I like to switch to conservative governor when on battery. I also change the up and down thresholds to 98 and 95, respectively as per this probably dated article: http://www.ibm.com/developerworks/libra … index.html .
Anyway, I have TLP set to switch to performance when plugged in and conservative when on battery. Is there any way to get TLP to also set the thresholds when the computer is unplugged? Any kind of "run this script upon unplugging" option? I think Laptop Mode Tools had that, so that would be the one thing which I'd say is better about LMT if TLP doesn't also have that.

Hello,
I would assign 8 CPUs to affinity mask (CPU) and 8 CPUs to I/O affinity mask per instance.
Please read about why you should not assign the both to the same schedulers on the following post.

Hope this helps.

Setting thresholds for Metrics in OEM

I want to set thresholds for metrics in OEM and everytime I do, the following error occurs.
Error occurred while editing the metric thresholds.
Communication exception occurred while saving the thresholds data to the emd.
Error
java.lang.Exception: No such metric
Does anyone have any idea why this is happening and what can I do to fix it.
Thank you

Hi.
Monitoring templates are not permanently associated with targets.
Applying a template on a target updates the target's settings but if you modify the template afterwards you need re-apply it.
Furthermore, you can apply more than one template on a target. The second apply operation will generally override settings applied in the first one.
(As a best practice I would make sure that if I use more than one template for a specific target type , the different templates will
include different metrics).
Apply operations are logged and you can check which template was applied against which target.
This is available under "past apply operations" in the templates page.
HTH,
Erez.

What is the best FC Pro Easy Set up for video shot with an iPhone 4?

what is the best FC Pro Easy Set up for video shot with an iPhone 4?

There isn't one. You have to convert the media to one of the ProRes codecs, probably ProRes LT would work best. You need to do this in Compressor.
Easy setup isn't relevant as it's options are for tape based media, which this isn't.

Shell script for cpu governor toggling [SOLVED]

I am fairly new to shell (bash) scripting, but i thought i would at least manage an if test, though i was proven wrong :/
I have been looking at this for way to long by now, and i am positive i am just missing the obvious, though I just cannot see where im wrong (checked alot of examples of similar bash scripts)
The problem is that the code runs as if the if statement is always true (as if the `cat /sys/.../scaling_governor` is never updated). So what I think might have a say is the fact that it gathers info from /sys/... since i have never done that before
#!/bin/bash
if [ `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor`="performance" ]
then
echo "conservative" >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "conservative" >/sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo "conservative" >/sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo "conservative" >/sys/devices/system/cpu/cpu3/cpufreq/scaling_governor
echo "cpu governor: conservative"
else
echo "performance" >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "performance" >/sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo "performance" >/sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo "performance" >/sys/devices/system/cpu/cpu3/cpufreq/scaling_governor
echo "cpu governor: performance"
fi
the code should "toggle" the governor for each core by checking 1 of them and applying it to all (I know the code probably looks sub-par, so if you can't handle it, please tell me how to improve it :P, or if there is a better solution to this whole thing altogheter)
Thanks in advance, and I will be trying to solve this in the mean time :)

That was a good idea AdmiralSpark (and also owain ), I didn't know that I could pass -r in cpufreq-set.
I really should be more thorough in my manual reading
I don't think i will be going for a GUI selection (though that is a good idea for this).
The next (and final) step for me would be to have some sort of pop-up message display what governor i switched to. (since I bound this to a button press event it will not display in active terminal?). But I havent really started looking into that yet, and should probably make another thread for that after i fail miserably .
Thanks again for the help & suggestions.

WADK components & setting used for power management with answer file for windows 8.1 ent

hello,
I have to deploy windows 8.1 ent device with MDT answer file related to power management with customized following settings:
High performances
sleep timeout settings
standby or sleep and hibernate setting
Enable critical battery task.
But don't know
1. how to manage power settings using answer file (WADK) for win8.1.
2. which OS Windows image component and setting used for power management in WADK.
Thanks
Richa Km

The way I do it with my task sequences (this works with MDT as well as SCCM) is to have an exported power plan using the POWERCFG -EXPORT command. I create a software package around the resulting *.POW file with a command do do an POWERCFG -IMPORT.
I then issue a POWERCFG -SETACTIVE command to the GUID of the *.POW file to enable that power scheme.
More information on the POWERCFG command can be found here:

How to set properties for HTTPClient came with WSClient_extends.jar ?

In my web service client application, we need cookie to maintain session between server and client.
I think the server cookie policy is not completely standards compliant since HTTP request to this server through Apache HTTPClient need to setup following:
"http.protocol.single-cookie-header" to be true
cookie policy to be "CookiePolicy.BROWSER_COMPATIBILITY"
My problem is, we are using Oracle WSClient_extends.jar for web service call, WSClient_extends.jar came with it own HTTPClient implemetation.
Are there equlivant properties can be set in Oracle HTTPClient similar to Apache HTTPClient to handle such cookie policy?
Thanks

Hi,
This is correct; see my blog entry: http://db360.blogspot.com/2007/01/is-your-java-application-failoverproof.html
However, you need to use oracle.jdbc.pool.OracleDataSource and from what i know Websphere does not (yet?) allow bypassing its own connection pool in favor of Oracle driver's embedded conection pool.

WorkFlow get triggered even if we set trigger for item update with SPEmailEventReceiver and workflow attached to same Library

Hi All,
I have a situation, SPEmailEventReceiver and WorkFlow is attached to same library, WorkFlow is configured to run after item is updated, but soon as the email is received in library the workflow
is getting triggered, We have a action to create folder with subject and date and put the attachment with the date folder in SPEmailEventReceiver e.g: once a mail is received in library the SPEmailEventReceiver will create a folder with Subject and then Folder
with Date and then put the attachment in the date folder so hierarchy will be subject folder/Date folder/attachment
I have tried to alter the SquenceNumber attribute in Feature Element file to 1 and make the Synchronization as synchronous but no luck.

SQL 2008R2 - Performance Condition alert for CPU Threshold event

I am trying to use SQLServer Agent alert for Resoure governor setup. I would like to be alerted when CPU threshold -> REQUEST_MAX_CPU_TIME_SEC > 20 -> is crossed for any particular query. I am in RTM version for SQL2008R2. For some reason
the alert never occurs thru SQL Agent Alert.
Here is my alert configuration
EXEC msdb.dbo.sp_add_alert
@name=N'CPU Alert',
@message_id = 0,
@severity = 0,
@enabled = 1,
@delay_between_responses = 60,
@include_event_description_in = 1,
@notification_message = N'Email from alert CPU',
@category_name = N'[Uncategorized]',
@performance_condition = N'MSSQL$XXXXXX:Workload Group Stats|Max request cpu time (ms)|default|>|1',
@job_id = N'00000000-0000-0000-0000-000000000000'
THe same alert is working if I put < 5, I am able to notified by email. But when I put > I dont see any alert.
I have tried changing the default setting for resource governor to various #s (1, 5, 20, 600) . But for any change, if i use perf condition > 5, i dont get any alert. If i use < 5 then i get alerts...
Is it a bug, or am i missing something...
Any help will be much appreciated...

Need Advise on Setting Critical Metric Threshold for "Status"

Hi All,
I am trying top copy all metric thresholds from OEM 9i to 10G. I ran across the metric threshold for "Status" (whether the node is up or down). It is set to "Down" and, although I'd like to set it to "Up/Down", when I hit Continue it comes back with
"The format of the critical threshold is not correct.". Does anyone know what the problem is?
Thanks
Sam

you are status metrics for all targets in grid control
the notification rules for databases,hosts,listener,aplication server are enabled the send mail if the status change.

Set metric threshold for default metrics

Running Grid Control 10.2.0.4; have not had the time to go through an upgrade to 10.2.0.5 yet.
There are several metrics I am interested in setting a threshold for, specifically the Streams Replication metrics. When I click the "All Metrics" link on the cluster database's homepage I see a category called Streams Process Count as well as several metrics within that group. Right now none of those metrics have thresholds set. I have tried adding a threshold in the monitoring config (Preferences -> Rules -> Database availability and critical states) but the Streams metrics do not appear.
Am I missing something here? I feel kind of ridiculous for asking, but I can't seem to find the answer anywhere...

Not every metric in 'all metrics' is configurable with metric thresholds.
Your workaround is to write an user definied metric.

Help: FSB Setting for MSI 875P with Intel 3.06 533Mhz & Corsair 512 27

Help: FSB Setting for MSI 875P with Intel 3.06 533Mhz & Corsair 512 2799 333Mhz
Need a little help here, Intel's specs for the P4 3.06GHz 533 is a multiplier of 23 x 133Mhz.
However 133Mhz as a FSB seems very slow.
The 875P NEO has two BIOS settings: CPU Ratio and Adjust CPU Bus
What are your settings for these - I am quite confused?
Thanks!
G.

133 is the stock FSB setting. set your memory to DDR333.
Do you want to overclock? you might want to set your memory to DDR266 which is 1:1. so u can adjust a bit of FSB from 133 to maybe 150.
PS dont forget your memory timing. 2-6-3-3 would be oki i think. what bios version r u using?

Hey Eric,
Thanks for taking the time. Unfortunately no that does not solve it. Same as swipe it will get me there and it will show separate programs spaced out. The issue I am having is that all my open word files are bunched up in a pile on top of each other. I can see the edges of each one but I want them to be separated from each other enough that I can visually identify what file is what.
Again, thanks for trying, it is appreciated.
