Load Testing with 1000 concurrent/virtual users - testing

I need a help, I am planning to perform load testing over a product and i am searching for a tool which can provided me the exact details and also can show me the whole statistics in relevance and also the timestamp.
I was searching for such tool. If anyone knows or comes across something like this than please let me know.
Thanks in advance to all who intend to help.

Pre-scriptum: I'm assuming you want to test a web app. Please, provide further details in the question.
Maybe it's too basic but, have you tried using ab?

The two I would start looking at as Jmeter and the Grinder. I would start with Jmeter and if this does not meet your requirements move on to the Grinder.

Program that can extract something from a website

I`m sorry if this is the not right place to ask. If not please delete this.
I`m looking for someone that can help me with a very simple program that can do this:
Login into accounts on an website and extract there a number from every account and and save the details ( account number - the number that must be saved ) on an txt file.
I need this for my job. This program will save me a`lot of time. this is the purpose.
If anybody can help me please let me know. thank you very much.
Fortunately for you, there is ample tooling available.
I will provide you some insight into related tools in the Python ecosystem, since that is what I am most familiar with and also an easy languages for beginners to work with.
If what you are extracting/scraping is relatively simple and doesn't require complex UI interaction with website elements, I would recommend requests Sessions to retain cookies and additional information for use in a series of authenticated requests, and bs4 to parse document trees in order to extract the data you are interested in.
For more complex interaction, you will need to look towards browser automation and possibly more advanced scraping frameworks. Hopefully I've given you enough keywords to go far in Google.
Of course, you'll need to first learn the basics of programming and how web data is structured if you want to write scripts like this. That is left to you to learn and absorb.

Hey everyone, im hoping someone can help me. I have a search page in a web app and im trying to construct a custom query to hand to my repository so that when a search is done, only when there are search parameters it will do something. I have the logic done so that it detects when there are parameters, but i still dont know how to construct the query and i cant find a simple enough example through my normal channels online. Can someone offer advice? Or forward me to an online resource? Thanks in advance!

What tools exist to find frequencies of searches

I'm new to seo, so please excuse what may be a very basic question.
I want to count (or estimate) the number of times that a given search phrase has been searched within a particular time period. Are there any API's out there for this? Does Google (or any other relevant search engine) release this information?
Any helpful links are greatly appreciated.
I'll be using Java, though I doubt that makes much difference.
I'm not aware of any API for it, but you can use Google Insights for Search
I use link text
it also presents the volume for every search
It looks like the WordTracker API might be the best took for programmatically finding search data.

Check out this improv API to Google Trends which helps you export data.

I would like to create an HTML help for one of my application, based on the Google help system. Does anyone know whether the Google Help system is available outside Google corp? If yes, how to obtain it. What is the authoring tool? Is it an open source tool?
If not, is there some authoring tool with the same flavour?
The type of help I would like to produce is the kind you get for instance at

Help building an E-commerce site

Guys, I want to build an e-commerce site on asp.net. My query is: when two users simultaneously buy something, how would the two records get inserted in my database? Would there be a lock? Can anyone explain how this would be or can be handled.
Also, I want to handle peak traffic and also control the average data allotted to each user. I am thinking of using a plug-in. Any suggestions here?
Just a thought but if your just starting a new online store its highly unlikely you'll run into any problems like this for some time?
Secondly, Databases take care of themselves and your web server does all the work of handling traffic and allocating resources. You shouldn't be doing this at a web code level.
The RDBMS handles the locking for you.
Maybe a better solution is a free ecommerce solution, as it'll have a lot of optimisation for large traffic already. Is there a specific reason not to use one of the many solutions already available?
