I am writing a status monitoring page for our test environment and would like a list of individual selenium/webdriver nodes which are registered with the Grid server. I can do this by scraping the information on /console but I was wondering if there is an api-like way.
Basically I'm looking to do obtain output similar to that of TestSessionStatusServlet but for all registered nodes.

I don't think there's currently anything shipping in Grid that provides that. However, you can register your own servlet when you start the hub up. If you subclass org.openqa.grid.web.servlet.RegistryBasedServlet you'll have full access to the Registry and can pull out any info that you need. I've done something very similar so I could audit when a node goes down.

I've created an application and I'd like to test how well it scales to large numbers of users.
To run my application a user has to go to the homepage, sign in to a Google account, click a button and then upload a video file.
First of all, is this possible to emulate using JMeter? I'm signed into my Google account locally but am not sure whether simulated users will have access to it?
Secondly, I've recorded a session in JMeter doing the actions above and have run the test with 10 simulated users, however, the App Engine dashboard doesn't detect any activity. I've followed the steps mentioned here but obviously with details of my application etc.
Here's a screenshot of the summary report.
Is there anything obvious I might be doing wrong? Am I using JMeter in the correct way to test the application as desired?
Apologies for my JMeter inexperience.
This is not something you will be able to record and replay, my expectation is that your application is protected by OAuth so you will need some token in order to execute your calls.
Not knowing the details of your application implementation it's quite hard to guess what's went wrong, I would recommend
Running your test with 1 user and 1 loop first to ensure that it's doing what it is supposed to be doing by adding View Results Tree listener and inspecting request and response details for each sampler (especially for failed ones).
Once you figure out what's wrong with this particular request - amend JMeter configuration so it would be successful. Repeat until you're happy with the test end-to-end.
Add load only after that and be careful as test might be sensitive to extra users/loops, especially if you're using a single login account (which is not recommended)

I am developing an application and decided Nagios3 for performing monitoring stuff. But I am stuck at two points. I am using check_http plug-in for monitoring load on my service api. Now I want to perform below tasks.
I need to set a threshold in check_http for performing some task after crossing that threshold. I tried below command
'check_command check_nrpe_1arg!check_service_api'
but it only tells me the load, not any threshold is set. while below one doesn't work.
'check_command check_service_api!100!200'
I need to send simple text message on some port(my application).
I am new to Nagios, so please help me figuring out the solution except email notification stuff.
There is a check command that you can download called "notify_sms" that integrates with an API server hosted by a company called Esendex. They charge for their service but it works well.
We were running on AppEngine but recently moved over to Managed VMs. For some reason AppStats is no longer available? We just get a 404 not found error when browsing to our appstats URL. Is appstats not supported on Managad VMs? If not, is there a way of isolating poorly performing endpoints within our application?
One way to isolate poorly performing endpoints is to use the advanced filter search in the GCP Logs Viewer. It is a little hard to find at first.
To get there, in your Google Cloud console, navigate to Logging for your project. At the right of the text box for "Filter by label or text search" you will see a small dropdown arrow. Click that and select "Convert to advanced filter". This will allow you to write your own sql-ish query where you can find requests that took longer than n to complete.
For example, add the following to the filter:
protoPayload.latency>"0.300s"
This will return a list of all requests that took longer than 300 milliseconds to process. If you have Cloud Trace enabled, you can click on the request response time to see the timeline for the individual service calls.
I would like to accesss the sitecore DB and items from console application like
Sitecore.Data.Database db = Sitecore.Context.Database
or
Sitecore.Data.Database db = Sitecore.Data.Database.GetDatabase("master")
how do I configure and setup my console application to access the DB as above?
Thanks Everyone for the suggestion, I am really interested in config changes, I used webservice, but it has very limited methods. For example, if I would like create an Item with the template and insert the item with prepopulated value, there is no such option. The reason I am looking for the console apporach is I would like to import the contents from XML or excel sheet and push those to the sitecore tree, eventually use the scheduled task to run the console app periodically. I do not want to copy the entire web.config and app_config. If anyone has already done this, could you please post your steps and necessary config changes?
You have two options I think:
1) Import the Sitecore bits of a website's web.config into your console application's app.config, so that the Sitecore API "just works"
I'm sure I read a blog post about this, but I can't find the reference right now. (I will have another look) But I think the simple but long winded approach is to copy all of the <sitecore/> element and all the separate files it references. I'm fairly sure you can whittle this down to a subset of the config required for data access with a bit of thinking.
2) Don't use the Sitecore API directly, connect to a web service that exposes access to it remotely.
There are a few of these that already exist. Sitecore itself exposes one, Sitecore Rocks has one, and Hedgehog TDS has one too. And you can always write your own (since any web service running inside the Sitecore ASP.Net app can make database calls and report values back and forth - just remember to consider security if this web service might end up exposed externally for any reason)
John West links to some relevant stuff here:

-- Edited to add --
I've not found the blog post I remember. But I came across this SO thread:
Accessing Sitecore API from a CLI tool
which refers to this blog post:
http://www.experimentsincode.com/?p=232
which I think gives the info you'll need for option 1.
(And it reminds me that, of course, when you copy the config stuff you have to copy the Sitecore binaries into your app's folder as well)
I would just like to expand on #JermDavis' post and note that Sitecore isn't a big fan of being accessed when not in a web application. However, if you still want to do this, you will need to make sure that you have all of the necessary configuration settings from the web.config and App_Config of your site in your console application's app.config file.
Moreover, you will never be able to call Sitecore.Context in a console application, as the Sitecore Context sits on top of the HttpContext which means that it must be an application and have a valid request for you to use it. What you are looking for is something more along the lines of Sitecore.Configuration.Factory.GetDatabase("master").
Good luck and happy coding :)
This sounds like a job for the Sitecore Item Web API. I use the Sitecore Item Web API whenever I need to access Sitecore data from the master database outside the context of the Content Management server or outside of the context of the Sitecore application. The Web API definitely does not allow you to do everything that the standard Sitecore API does but it can act as a good base and I now extend upon the Web API instead of writing my own custom web services whenever possible.
Thanks to JemDavis's advise.
After I copied the configuration and made changes to config section to get rid of conflicts. I copied almost all of Sitrecore, analytics and lucene dlls, it worked great.
Only thing you have to remember is, copy the app_config folder to the same location where your dlls are.
Thanks again JemDavis....
I have one very weird question.
There are 2 Silverlight Client
1. Admin
2. User
Now, I want a scenario wherein the Admin Silverlight can initiate a function call on the User Silverlight.
Pretty much a newbie with SL so wonder if that would be possible.
I'd appreciate any help.
Thanks
I suppose the applications are not in the same browser / machine, and when you describe the usage pattern as admin and user, I take that there are probably more users than admins.
You might want to take a look at duplex bindings for WCF services - this is a web service binding that allows pushing notifications to clients from the server. When all clients establish such a channel, you can implement hub-and-spoke communication between clients.
This blog post gives a good receipt for getting started:
http://silverlightforbusiness.net/2009/06/23/pushing-data-from-the-server-to-silverlight-3-using-a-duplex-wcf-service/
If they are both in the same frame/browser, you could call JavaScript in the first using the HtmlPage API, which could interact with the second.
So:
Silverlight control -> injects JS into HtmlPage -> JS interacts with Silverlight control 2 (assuming this is possible, please correct me if wrong) -> Silverlight control responds.
If they are in separate windows or running "out of browser", I would expect it wouldn't work.
If the 2 instances are seperated (i.e., the admin is on one machine and the user is on another) there's no direct way to do it. However, you can rig it up with a publisher/subscriber style system.
Assumption: You have some sort of shared data store between the two, maybe a database or something.
Idea: You have the admin client write a request to this shared data store; an entry in a table, or a new file in a network share, or something. You have the user client app regularly scan this table/share for new entries, say every .5 seconds or so. When it sees the entry, it executes the requested operation, storing any return values back to the shared store. When the admin sees the return value, he knows the operation has been successfully executed.
There are a couple of options that I can think of.
You could implement some sort of remote procedure call via web services whereby one Silverlight app posts a request to call the method, and the other Silverlight regularly checks for method call requests.
If hosted on the same HTML page in a browser, you could use javascript to allow the two controls to interact.
However, direct communication between two Silverlight instances isn't supported, and while the suggestions may help to achieve something close to what you want, they don't provide a complete solution that will work in all scenarios.
