  • Measuring performance indicators on a cluster

    - by Aditya Singh
    My architecture is based on Amazon. A ELB load balancer balances POST requests among m1.large instances. Every instance has a nginx server on port 80 which distributes the requests to 4 python-tornado servers on backend which handle the request. These tornado servers are taking about 5 - 10ms to respond to one request but this is the internal compute time of every request. I want to put this thing on test and i want to measure the response time from ELB to upstream and back and how does it vary when the QPS throughput is increased and plot a graph of Time vs. QPS vs. Latency and other factors like CPU and Memory. Is there a software to do that or should i log everything somewhere with latency checks and then analyze the whole log to get the stuff out. I would also need to write a self-monitor which keeps checking the whole response time. Is it possible to do it with a script from within the server. If so, will it be accurate ?

  • Could 0x800CCC0E in Outlook be caused by bad wireless connection?

    - by AndrejaKo
    I have a computer connected to a WiFi access point/router/modem. Sometimes, I get page not found errors and similar when opening a browser window, sometimes pings fail and it looks like the router's signal isn't very good. On the other hand, I get around 4 bars of signal strength in windows and graph looks good in Inssider. I also never get dropped connection to the router. My main problem is that I often get errors (such as 0x800CCC0E) in Outlook 2010 that after some searching appear to be connected to bad server connection. I'm using GMail over IMAP and all settings are correct. I didn't have similar errors on my previous router, but I'm not 100% sure that they appeared after switching to current one. It may have worked for some time without errors. There are also around 3000 messages on the server and the size of mailbox is around 12 GiB, which may contribute to the problems. On the other hand, there are at least 24 other networks in the 2.4 GHz range which I'm using and the number may have increased since I switched routers. Should I try solving this by getting a router with stronger signal?

  • Creating dynamic map graphs

    - by Mehper C. Palavuzlar
    I need a software (or softwares) to achieve the following. I'm not sure if it could be done, but I'd like to hear the suggestions from super users. The data I want to use for graphing purposes include sales figures of magazines by provinces. There are 81 provinces of Turkiye, and I want the computer to automatically paint / write on a graph according to the sales magnitude of the provinces. Since there are loads of magazines with loads of issues, the process must be executed automatically just after selecting the related magazine and issue. So there will be graphs showing the sales weight of the whole country with some nice illustrations. Those graphs might be used as part of some decision support mechanism to help field teams. Is it possible? I have all the data and base maps of Turkiye to be filled/painted. I'm sure this is not easy. If there is a way to do that, it might probably include more than one software. Thanks in advance for any valuable comments and answers.

  • quad sli with gtx 690 not working

    - by Moaadh
    I have two cards GTX 690 (dual core). I did the Sli successfully. Nvidia control panel acknowledges the two cards as quad Sli. However, the problem is that Windows 7 64-bit Ultimate is showing me the graph memory size as 4 GB while it is supposed to be 8 GB because of the Sli. Also the benchmark from all software is giving me a very low score compared to some other guy's benchmark on YouTube. It gives me a big headache. Does anyone know why this is happening? If so, how can I get Windows 7 to recognize all 8 GB of memory? Thanks for your help in advance. My computer specifications: (Processor: Intel Core i7-3930k @3.2GHz(12CPUs))--- (Memory: 65536 MB Ram 1866 MHz)-- (OS: Windows 7 Ultimate 64-bit)-- (OCZ 240GB as SSD PCIe drive for booting and storage disk)-- (DirextX version: DirectX 11)-- (VGA Card: 2 X EVGA GTX 690 Dual GPU. Each GPU is 2 GB, so total memory should be 8 GB.)-- (MotherBoard: ASUS Rampage IV Extreme)-- Others with lesser specifications get a 2500 score in heaven benchmark while I get 1501 as if it is one card.

  • Debian 100% cpu every 30 minutes but not loggable?

    - by user654123
    I have a Debian 7 x64 machine running with Digital Ocean that has every 30 Minutes a 100% cpu usage for about 1 minute. A couple of days ago it stayed there for a couple of hours so the server finally crashed and I had to repair my Mysql databases. The server is a pure webserver running apache2 and Mysql. I tried tracing which processes use the cpu but with no luck. The script I used: #!/bin/sh while true; do ps -A -eo pcpu,pid,user,args | sort -k 1 -r | head -3 >> proclog.txt; echo "\n" >> proclog.txt; sleep 2; done I was monitoring htop as well while this was happening, but the top processess' cpu usage didn't add up to ~15% even though htop's cpu meter showed constant 100%. htop was configured to show all users' processess, user- and kernel-threads. Edit: By stopping Apache2 & Mysql prior to the expected 100% usage I can tell both are not responsible for it. The 100% usage occurred anyway. This is what the graph looked like the past hours:

  • vSphere education - What are the downsides of configuring virtual machines with *too* much RAM?

    - by ewwhite
    VMware memory management seems to be a tricky balancing act. With cluster RAM, Resource Pools, VMware's management techniques (TPS, ballooning, host swapping), in-guest RAM utilization, swapping, reservations, shares and limits, there are a lot of variables. I'm in a situation where clients are using dedicated vSphere cluster resources. However, they are configuring the virtual machines as though they were on physical hardware. In turn, this means a standard VM build may have 4 vCPUs and 16GB or more of RAM. I come from the school of starting small (1 vCPU, minimal RAM), checking real-world use and adjusting up as necessary. Some examples from a "problem" cluster. Resource pool summary - Looks almost 4:1 overcommitted. Note the high amount of ballooned RAM. Resource allocation - The Worst Case Allocation column shows that these VMs would have access to less than 50% of their configured RAM under constrained conditions. The real-time memory utilization graph of the top VM in the listing above. 4 vCPU and 64GB RAM allocated. It averages under 9GB use. Summary of the same VM What are the downsides of overcommitting and overconfiguring resources (specifically RAM) in vSphere environments? Assuming that the VMs can run in less RAM, is it fair to say that there's overhead to configuring virtual machines with more RAM than they need? What is the counter-argument to: "if a VM has 16GB of RAM allocated, but only uses 4GB, what's the problem??"? E.g. do customers need to be educated? What specific metric should be used to meter RAM usage. Tracking the peaks of "Active" versus time?

  • Can I select which folders the Photos live tile chooses from?

    - by nhinkle
    The built-in Photos app in Windows 8 has a live tile on the start screen that shows photos from your pictures library. It's a cool little visual, even if it's not particularly useful. The problem is that a lot of image files on my computer are not really photos per se -- I have a lot of screenshots, PNGs of technical drawings, graph images, etc. Those all look pretty awkward on the start screen. I look pretty awkward on the start screen too... sometimes photos like resume profile shots show up that I don't want to delete, but they're not really what I want to be staring at when I start my computer up. I'm looking for some way to configure which folders the Photos app should look in for images to display on the live tile. That way, I could point it to some directories of pretty scenic pictures I've taken, and not have to see graphs and my own mug. For the time being, I've just disabled the live tile (right click - disable live tile), but I would ultimately like to have this functionality, just with more control over it.

  • Ubuntu's garbage collection cron job for PHP sessions takes 25 minutes to run, why?

    - by Lamah
    Ubuntu has a cron job set up which looks for and deletes old PHP sessions: # Look for and purge old sessions every 30 minutes 09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] \ && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 \ -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir \ fuser -s {} 2> /dev/null \; -delete My problem is that this process is taking a very long time to run, with lots of disk IO. Here's my CPU usage graph: The cleanup running is represented by the teal spikes. At the beginning of the period, PHP's cleanup jobs were scheduled at the default 09 and 39 minutes times. At 15:00 I removed the 39 minute time from cron, so a cleanup job twice the size runs half as often (you can see the peaks get twice as wide and half as frequent). Here are the corresponding graphs for IO time: And disk operations: At the peak where there were about 14,000 sessions active, the cleanup can be seen to run for a full 25 minutes, apparently using 100% of one core of the CPU and what seems to be 100% of the disk IO for the entire period. Why is it so resource intensive? An ls of the session directory /var/lib/php5 takes just a fraction of a second. So why does it take a full 25 minutes to trim old sessions? Is there anything I can do to speed this up? The filesystem for this device is currently ext4, running on Ubuntu Precise 12.04 64-bit. EDIT: I suspect that the load is due to the unusual process "fuser" (since I expect a simple rm to be a damn sight faster than the performance I'm seeing). I'm going to remove the use of fuser and see what happens.

  • Perfmon % Processor Time vs. task manager's CPU usage

    - by nat
    I'm new to using Perfmon and performance monitoring in general (so go easy on me please ;) I know that Perfmon doesn't have anything exactly like Task Manager's CPU usage display, but I'm trying to figure out how to monitor user's CPU usage via Perfmon in a similar way, and trying to understand the measurements (or how to convert the numbers to get a similar understanding) For example, if in Task Manager, a particular user is consistently using more than 5% CPU, I would want to contact the user about it. I learn best by example, so here is exactly what I'm trying to do, with a specific example: This is for a 32-bit Dual Quad Core Windows 2003 web server (8 CPUs), there are many web sites on the server, each running within their own application pool/worker process ID. Through other research here I learned of a registry change that I made so that the PID shows up with the w3wp process so I can easily identify the site later by cross-referencing it. I set up a counter with the following settings: Process -> % Processor Time -> all instances Here is an example. Say I'm interested in "black line" user in this graph below, as his process is spiking quite high compared to all the other users: (I wasn't allowed to post the image as I'm a new user on this site.. I've uploaded the image to:) http://i35.tinypic.com/106yn8k.jpg So... using this as an example, I see that they have an AVERAGE % PROCESSOR TIME of 23.264 , and have spiked as high as 103.124 So what exactly does this 23.264 number mean to me? Is it similar to an average of Task Manager's CPU reading for this user? Or, since this server has 8 CPUs, should I divide this number by 8? (23.264/8 = 2.9% AVERAGE CPU LOAD?) Thanks in advance.

  • Android - HorizontalScrollView within ScrollView Touch Handling

    - by Joel
    Hi, I have a ScrollView that surrounds my entire layout so that the entire screen is scrollable. The first element I have in this ScrollView is a HorizontalScrollView block that has features that can be scrolled through horizontally. I've added an ontouchlistener to the horizontalscrollview to handle touch events and force the view to "snap" to the closest image on the ACTION_UP event. So the effect I'm going for is like the stock android homescreen where you can scroll from one to the other and it snaps to one screen when you lift your finger. This all works great except for one problem: I need to swipe left to right almost perfectly horizontally for an ACTION_UP to ever register. If I swipe vertically in the very least (which I think many people tend to do on their phones when swiping side to side), I will receive an ACTION_CANCEL instead of an ACTION_UP. My theory is that this is because the horizontalscrollview is within a scrollview, and the scrollview is hijacking the vertical touch to allow for vertical scrolling. How can I disable the touch events for the scrollview from just within my horizontal scrollview, but still allow for normal vertical scrolling elsewhere in the scrollview? Here's a sample of my code: public class HomeFeatureLayout extends HorizontalScrollView { private ArrayList<ListItem> items = null; private GestureDetector gestureDetector; View.OnTouchListener gestureListener; private static final int SWIPE_MIN_DISTANCE = 5; private static final int SWIPE_THRESHOLD_VELOCITY = 300; private int activeFeature = 0; public HomeFeatureLayout(Context context, ArrayList<ListItem> items){ super(context); setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); setFadingEdgeLength(0); this.setHorizontalScrollBarEnabled(false); this.setVerticalScrollBarEnabled(false); LinearLayout internalWrapper = new LinearLayout(context); internalWrapper.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); internalWrapper.setOrientation(LinearLayout.HORIZONTAL); addView(internalWrapper); this.items = items; for(int i = 0; i< items.size();i++){ LinearLayout featureLayout = (LinearLayout) View.inflate(this.getContext(),R.layout.homefeature,null); TextView header = (TextView) featureLayout.findViewById(R.id.featureheader); ImageView image = (ImageView) featureLayout.findViewById(R.id.featureimage); TextView title = (TextView) featureLayout.findViewById(R.id.featuretitle); title.setTag(items.get(i).GetLinkURL()); TextView date = (TextView) featureLayout.findViewById(R.id.featuredate); header.setText("FEATURED"); Image cachedImage = new Image(this.getContext(), items.get(i).GetImageURL()); image.setImageDrawable(cachedImage.getImage()); title.setText(items.get(i).GetTitle()); date.setText(items.get(i).GetDate()); internalWrapper.addView(featureLayout); } gestureDetector = new GestureDetector(new MyGestureDetector()); setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (gestureDetector.onTouchEvent(event)) { return true; } else if(event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL ){ int scrollX = getScrollX(); int featureWidth = getMeasuredWidth(); activeFeature = ((scrollX + (featureWidth/2))/featureWidth); int scrollTo = activeFeature*featureWidth; smoothScrollTo(scrollTo, 0); return true; } else{ return false; } } }); } class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { //right to left if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { activeFeature = (activeFeature < (items.size() - 1))? activeFeature + 1:items.size() -1; smoothScrollTo(activeFeature*getMeasuredWidth(), 0); return true; } //left to right else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { activeFeature = (activeFeature > 0)? activeFeature - 1:0; smoothScrollTo(activeFeature*getMeasuredWidth(), 0); return true; } } catch (Exception e) { // nothing } return false; } } }

  • checkbox unchecked when i scroll listview in android

    - by Mathew
    I am new to android development. I created a listview with textbox and checkbox. When I check the checkbox and scroll it down to check some other items in the list view, the older ones are unchecked. How to avoid this problem in listview? Please guide me with my code.

  • Android page Curl animation

    - by Meymann
    Hi... Two questions: Is there a simple way to do the Curl page flipping animation? A Curl animation is animation of pages flipping, including the page above rolling and the shadows over the lower page. What is the recommended way to do a "gallery" that displays two pages at a time (just like a book)? Is it: Letting the adapter display a linear layout of two images at a time? (it won't let me show a page flipping over the other like a book) Using two pages, placing somehow one near the other, and then when it's time to animate -move the next two pages over? What is the better way that would enable displaying the left page flipping over the right page? Thanks Meymann

  • MVC HTML.RenderAction – Error: Duration must be a positive number

    - by BarDev
    On my website I want the user to have the ability to login/logout from any page. When the user select login button a modal dialog will be present to the user for him to enter in his credentials. Since login will be on every page, I thought I would create a partial view for the login and add it to the layout page. But when I did this I got the following error: Exception Details: System.InvalidOperationException: Duration must be a positive number. There are other ways to work around this that would not using partial views, but I believe this should work. So to test this, I decided to make everything simple with the following code: Created a layout page with the following code @{Html.RenderAction("_Login", "Account");} In the AccountController: public ActionResult _Login() { return PartialView("_Login"); } Partial View _Login <a id="signin">Login</a> But when I run this simple version this I still get this error: Exception Details: System.InvalidOperationException: Duration must be a positive number. Source of error points to "@{Html.RenderAction("_Login", "Account");}" There are some conversations on the web that are similar to my problem, which identifies this as bug with MVC (see links below). But the links pertain to Caching, and I'm not doing any caching.

  • Extjs Tooltips, IFrames and IE => Problems

    I have an application using OpenLayers, Extjs and GeoExt. My application runs fine, but I need it to be placed inside an IFrame in another page. When doing this, my toolbar becomes responseless in Internet Explorer. The cause is Ext.QuickTips.init();. Comment out this line and everything works fine - except the quick tips ofcourse =) But why is it causing problems? Is it because I'm using it wrong, placing it wrong or just because it doesn't like IE and IFrames?

  • Where can I download an english version of the Sony Bravia SDK & Emulator?

    - by Kevin Williams
    I recently purchased a Sony Bravia TV that comes with Internet capability built in. It supports a number of 'widgets' and apps built for youtube, twitter, various yahoo! offerings and apparently AOL & Netflix if I were in the USA. I'd like to hack on the SDK, but the only version I can find is Japanese. Where is a good source of information (in English)? Japanese SDK Documentation (English Layout & JavaScript API pdfs included)

  • How to Set Opacity (Alpha) for View in Android

    - by ncakmak
    I have a button as in the following: <Button android:text="Submit" android:id="@+id/Button01" android:layout_width="fill_parent" android:layout_height="wrap_content"></Button> In my onCreate event, I am calling Button01 like this: setContentView(R.layout.main); View Button01 = this.findViewById(R.id.Button01); Button01.setOnClickListener(this); There is a background in the application, and I want to set an opacity on this submit button. How can I set an opacity for this view? Is it something that I can set on the java side, or can I set in the main.xml file? On the java side I tried Button01.mutate().SetAlpha(100), but it gave me an error. Thank you.

    I'm working on an app that calls a web service, then the webservice returns an array list. My problem is I am having trouble getting the data into the ArrayList and then displaying in a ListView. Any ideas what I am doing wrong? I know for a fact the web service returns an ArrayList. Everything seems to be working fine, just no data in the ListView or the ArrayList.....Thanks in advance!

  • Android SlidingDrawer in Eclipse IDE

    - by user295447
    I am trying to design an application for Android that makes use of the SlidingDrawer, but I have not been able to use the form (layout?) designer to add this element without producing an exception "IllegalArgumentException: The handle attribute is required and must refer to a valid child." As of March 17th, I believe I have everything up to date (Eclipse, and the Android SDK). All the SDK components have been installed. I have created two Android virtual devices, One for version 1.0, and one for version 2.1 when I figured out that 1.0 didn't support the SlidingDrawer. I have tried importing the samples provided in the SDK, as well as several other layouts from the web that I have found, all of which produce this same exception. My programming background is mostly C++, and I consider myself to be a novice programmer, so feel free to talk to me as if I were an idiot so that I will understand. ^^;

    - by varun
    Hi, I am new to Blackberry Development.This is my first Question for you people. I am creating a search box for my project. But it looks like blackberry doesn't have an internal api for creating single line Edit field. I have created a Custom Field by extending BasciEditField overriding methods like layout, paint. In paint i am drawing a rectangle with getpreferred width and height. But the cursor is coming at default position (top-left) in Edit Field. Can any body tell me how i can draw it where my text is(i.e in middle of Edit Field by calling drwaText()). Thanks,

  • UITableViewCell with custom gradient background, with another gradient as highlight color

    - by Rich
    I have a custom UITableViewCell with a custom layout. I wanted a gradient background, so in my UITableViewDelegate cellForRowAtIndexPath: method, I create a CAGradientLayer and add it to the cell's layer with insertSubLayer:atIndex: (using index 0). This works just fine except for two things: Most importantly, I can't figure out how to change to a different gradient color when the row is highlighted. I have tried a couple things, but I'm just not familiar enough with the framework to get it working. Where would be the ideal place to put that code, inside the table delegate or the cell itself? Also, there's a 1px white space in between each cell in the table. I have a background color on the main view, a background color on the table, and a background color on the cell. Is there some kind of padding or spacer by default in a UITableView?

  • Dismiss android preferences dialog on Keyboard ACTION_DONE press

    - by Damian
    I would like to be able to close the editpreference dialog (as shown here http://twitpic.com/18ttdp) by pressing the 'Done' button on the keyboard. Currently, pressing 'Done' just dismisses the keyboard but leaves the dialog. In other parts of my application I use code similar to the following to intercept the 'Done' key press and execute actions in my activity: text.setOnEditorActionListener(new TextView.OnEditorActionListener() { @Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { if (actionId == EditorInfo.IME_ACTION_DONE) { //do stuff here return true; } return false; } }); However, I am unsure of how to do achieve this same effect in my preference activity or layout xml.
