Is there a way through the brasiers like firebug or another browser plugin to do traces or log console from a cfc file.
I'm completely new to CF so sorry if this seems like a stupid question.
If you want logs to be visible in the browser ColdFire is your best choice. With it, you can see all of ColdFusion's extended debugging information even on a production site. Unless you have the proper authentication via ColdFire the server won't spit out the extended info.
As #gillesc recommended, you can use LogBox which is extracted from the ColdBox framework. The ColdBox Framework has a debugging mode that allows you to trace messages to the bottom of the page, or, to a separate window. This is useful even on production sites since you can observe the tracer methods from other users.
Finally, you can simply print to the console using writeDump(var="my log message",output="console") for quick debugging--or--use the <cflog> tag to save log messages to a named log file which you can monitor using tail. For a dead simple solution, you can save the log file to the root of your site and simply press F5 to see the new log entries; however, I do not recommend this practice (unless you are saving credit card information and share that file with me :).
Hope this reply helps.

There is a cftrace tag that will allow you to log output to the console, among other spots in your application and development environment.
<cftrace category="init data" type="Information" var="myvartooutput" />
Calling this tag will output the relevant content in a few places:
The console in ColdFusion Builder, if you are using that IDE
In Dreamweaver, the Adobe docs mention a server debug tab/view (I don't use DW, so am not sure)
At the end of the request in the debug output
In cftrace.log, which is in your log directory (/COLDFUSION/INSTALL/DIR/logs/cftrace.log)
You can also use the tag cflog to write data to one of the standard log files or you may choose to have it write the desired data to a custom log file.
<cflog file="customlog" application="no" text="Output #somevar#!" />
If "customlog" does not exist, CF will create it for you (in the same location noted above).
Hope that helps!
EDIT: I offered this more of an alternative way to using to Firebug ... if you want the logs/traces but were not necessarily wed to a browser/plug-in.
If you've got CF Builder you can actually set up a debugger, but it's terribly slow. Here's the documentation on that: http://help.adobe.com/en_US/ColdFusionBuilder/Using/WS0ef8c004658c1089-31c11ef1121cdfd6aa0-7fff.html
There's also ColdFire, which is a Firebug add-on. Never used it before but I hear good things: https://github.com/nmische/ColdFire/

I'm able to successfully call my functions and make them do what I want them to do. The problem is that it doesn't look like the logs are being saved anywhere and I don't see how I can view them. Which I'll want to do in the event of an error. As a test I have my working function just doing a log.Info as soon as it's called. When testing locally it prints the message to the console. I believe I've enabled everything correctly but let me explain what I've done in case I didn't.
In my app service, under Monitoring -> Diagnostic Logs, I have enabled everything. Application Logging (filesystem) verbose, Application Logging (Blob) verbose (with the storage location set), detailed error messages and failed request tracing turned on.
In my function, I'm using the TraceWriter object that's passed to my run method (I started from a template).
Please note that functions are set to require authentication. If I click on the "Monitor" tab nothing appears. It just says "Loading..." forever and there's no information. Perhaps this is because of the authentication?
I used the Azure Storage Explorer to browse to my blob. The "log" blob exists, and I do see a set of nested directories that lead up to now. However it just contains a 354 byte file that contains a few lines of some random info. This file never seems to update or get larger.
I used FTP to try and browse to where the logs might be, but there's no directory on there that contains any log files.
I also went to KUDU for my function app ({myfunctionapp}.scm.azurewebsites.net/azurejobs/#/functions). While I do see that my function was called successfully, I don't see anything from the call to log.Info anywhere.
I tried using a different logger, and as a test did: System.Diagnostics.Trace.TraceError("test error");
I also don't see this message appearing anywhere.
Am I missing something as far as set up goes? Is the problem the fact that I require authentication? If it's the latter, is there still a way to view logs? I definitely have to have auth enabled. Thanks. And if it helps, below are links to what my settings and the monitor tab look like.
Settings: https://postimg.org/image/u57m2xbl5/
Monitor: https://postimg.org/image/uou10arch/
Authentication should not cause any problems with logging and Log.Info should work out of the box, no setup required.
I highly recommend that you enable AlwaysOn for your dedicated function app. The long loading of the Monitor tab could be because your site is in a 'cold' state, where it takes longer to start up.
If you go to {myfunctionapp}.scm.azurewebsites.net/DebugConsole and navigate to LogFiles/Application/Functions do you see any expected logs there? Also, when you run a function from the portal do you see logs in the log window?
Same thing happened to me if I had Fiddler open....close Fiddler and all is good.
I'm working with a production system that has a moderate amount of load. The amount of trace events and AI sends up is way too detailed, and makes it difficult to wade through logs later.
Each request to the server has information such as:
Message='Selected formatter='JsonMediaTypeFormatter', content-type='application/json; charset=utf-8'', Operation=DefaultContentNegotiator.Negotiate
and
Message='Action returned 'RZ.API.Support.Controllers.OperationActionResult`1[System.Collections.Generic.List`1[RZ.Entity.System.ClientMessage]]'', Operation=ReflectedHttpActionDescriptor.ExecuteAsync
There are maybe 30 entries for each request!
I just need the request type:
12/16/2015, 9:17:29 AM - REQUEST
GET /api/v1/user/messages
And the result code - as well as any custom stuff I do along the way.
So basically I want to trim most the traces except the request and the result (and any errors etc).
I have my eye on this bad boy in the AI config:
<Add Type="Microsoft.ApplicationInsights.Web.RequestTrackingTelemetryModule, Microsoft.AI.Web"/>
... but I cannot for the life of me see any doco on how to ask it to reduce the amount of stuff that is sent!
Any help is much appreciated.
Jordan.
P.S. All the extra logging has put us over the 15m a month plan, we had to upgrade!
RequestTrackingTelemetryModule does not do anything like you described. It adds requests, exceptions and dependencies collection. And in you example you are saying you see verbose WebApi traces being forwarded to ApplicationInsights. I assume you actually use Application Insights logging adapter.
Here you can read how WebApi traces can be forwarded to AI Version 1: http://apmtips.com/blog/2014/11/13/collect-asp-dot-net-mvc-web-api-traces-with-application-insights/
Here you can read how WebApi traces can be forwarded to AI Version 2:
http://apmtips.com/blog/2016/01/05/webapi-tracing-powered-by-ai-in-vs2015-update1/
Source code of logging adapters: https://github.com/Microsoft/ApplicationInsights-dotnet-logging
Documentation: https://azure.microsoft.com/en-us/documentation/articles/app-insights-search-diagnostic-logs/#trace
So you have multiple options:
Do not use logging adapters
Change verbosity of WebApi tracing (read http://www.asp.net/web-api/overview/testing-and-debugging/tracing-in-aspnet-web-api). I would prefer this one since you probably want to collect failures.
Remove WebApi tracing (as you did)
To answer my own question.
In my WebApiConfig file, I had:
config.EnableSystemDiagnosticsTracing();
Removing this line drastically cut down the clutter to what I was trying to achieve.
As of version 2.0 of the Application Insights SDKs, you can also limit the data sent by enabling sampling:
https://azure.microsoft.com/en-us/documentation/articles/app-insights-sampling/
if you add
<MaxTelemetryItemsPerSecond>5</MaxTelemetryItemsPerSecond>
to your ApplicationInsights.config, the sdk can limit how much goes out. The article above has a LOT more settings/configuration you can use to get other specific behavior, but the one above is the simplest.
As far as I know there are no configuration options available for the RequestTrackingTelemetryModule. You could just turn it off (by uninstalling the respective NuGet package or commenting the xml) and / or install different / additional telemetry modules.
See app-insights-configuration-with-applicationinsights-config for a list of modules and configuration options.
In my content script, I want to monitor which file a is getting uploaded to a web application.
I monitor "change" event for any "input:file" element. It works on any site (such as Gmail) that uses "input:file".
However sites like imgur, use SWFUpload mechanism. I tried to capture "fileQueued" event on element that I suspected to be swfupload. But that did not work.
How can I capture file upload event for sites that use swfupload?
Are there any other plugins that manage file uploading that I would need to take care in my content script?
Is there any generic mechanism to tackle this problem?
(I am aware of drag-n-drop mechanism, but I have not handled that case so far.
I have also read following relevant question on SO:
Grab file with chrome extension before upload)
It's probably worth your time to experiment with the chrome.webRequest API; it appears that the onBeforeRequest event contains info about file uploads. It's a complex API with extra parameters to addListener; read the docs thoroughly.
I try to call XSP._isDirty() for XPINC but it does not work. In the browser everything works fine. Is there a trick how i can use it.
Is there a way how i can see clientside errors when i'm executing XPages in the Notesclient?
Two questions here.
Q1. XSP._isDirty()
XSP._isDirty() is an internal call. From the XPages portable command guide (page 156).
XSP._isDirty() : Used internally by the Dirty Save feature— see the <xp:view> properties for enableModifiedFlag. This is a private function.
Code for this call is in the file xspClientDojo.js (look for the uncompressed file on Domino/Notes).
As it is an internal call it is used at risk. There is no guarantee it will work as expected in later versions.
The enableModifiedFlag is an XPage attribute that allows you to mark the page as dirty and prevent the user accidentally leaving the page. There are more details about this on the Infocenter.
Q2. Client side debugging.
You can review client side errors using the developer panel of most modern browsers, or something like the firebug plugin. The XPages extension library comes with a Firebug Lite component you can use as well.
For SSJS and XSP engine issues you can review these in the Notes client by reading the XPages logs in the IBM_TECHNICAL_SUPPORT folder contained in the Notes data folder.
For a "live" method of this is to modify the shortcut that launches notes as follows:
Target: C:\Lotus\Notes\notes.exe -RPARAMS -console -debug -separateSysLogFiles -consoleLog
Start In : C:\Lotus\Notes\framework\
Change the path to match your clients install.
I'm wondering, is it even possible to treat the request for the Xul Browser component to open a new window? I tried changing the window.open function, but looks like it's never called.
All links that open in a new window are not opening in my application.
I found this page on the subject, but the provided solution is showing no different behavior.
Any hint on this?
(by the way, I'm developing a stand alone application, not a Firefox's extension)
I'm assuming you are in a XULRunner application, and that you are trying to load a chrome URL from a non-chrome source in a browser (e.g. HTTP or local file). While enabling UniversalXPConnect and UniversalBrowserWrite can be helpful, they are also a security risk (since any arbitrary script on the web could use them), so they tend to be disabled in browsers (for example, running that line in Firebug will give you an exception):
>>> netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect UniversalBrowserWrite");
Error: A script from "http://stackoverflow.com" was denied UniversalXPConnect UniversalBrowserWrite privileges.
How about you try using codebase security principals and see if that makes a difference? (http://www.mozilla.org/projects/security/components/signed-scripts.html#codebase). For me in Firebug it does allow me to get the additional permissions after I OK it with a big, nasty looking dialog), but still doesn't allow me to open a Chrome URL with window.open. The next step is probably to try changing your conf file to use contentaccessible so that the relevant parts of your content are accessible (see https://developer.mozilla.org/en/Chrome_Registration#contentaccessible).
To avoid the nasty message when elevating permissions, you could try setting permissions for the right files automatically as described at http://forums.mozillazine.org/viewtopic.php?f=38&t=1769555.
Also, make sure you check the browser type (https://developer.mozilla.org/en/XUL/Attribute/browser.type). If the browser type is not chrome, then it might be worth trying making it chrome and seeing if that makes a difference.
If any of my assumptions are wrong get back to me and I will try something else.
does normal js not work?
window.open(url,windowname,flags);
There are two ways that I know of.
The first is to set the browser.chromeURL preference to a chrome URL that contains a <browser type="content-primary">. The page that the content window tried to open will load into the given browser.
The second is to set the property window.browserDOMWindow with an object that you define to implement the nsIBrowserDOMWindow interface. This allows you to divert the open call into a tab, if you are using a tabbed interface. Note: the tabbed browsing preferences must be set to allow windows to be diverted into tabs, otherwise XULrunner will fall back on browser.chromeURL.
