Problem Customers are unable to download adrum js files from cdn location( cdn.appdynamics.com) . The error message for each customer may differ. For example, some common errors seen are: When you try to click download option, it says No jsagent file can be download from cdn.appdynamics.com. When you click on the download option, it just navigates and throws HTTP 400 or Error 404. OR when you click on the "Download" button, the page keeps on "waiting" for the server for a very long time, then redirects you to the Controller restAPI download token. It will look something like this: http://controllerhost:8090/controller/restui/browserRUMConfig/downloadJSAgentZip?X-CSRF-TOKEN=4af3c63838922874d558da04b9dff079e07d1afb* It then immediately closes the connection with an unexpectedly closed the connection message. Environment (AppD Version, Other Products Installed) affected: This issue is seen on 4.3.x and 4.4 controllers. Troubleshooting/Resolution There can be multiple factors behind this download issue, so debug them step-by-step and apply the respective solutions as needed: Case 1: Check if there is an internet connection on the Controller machine. Many times the Controller machine does not have internet so it can't connect to c dn.appdynamics.com for downloading files. Solution Case 1: If you can not get internet on the Controller machine, you can use one of the workarounds given in the last section (Quick Fix) of this article. Case 2: The firewall is blocking the connection to cdn.appdynamics.com on port 443. Solution Case 2: You need to open the firewall to connect to the CDN site in order to download the JSAgent files Case 3: There is a proxy in between. Solution Case 3: If the Controller server is connected to the internet via http/https proxy, verify the controller proxy settings are set up correctly. If not, your network team needs to set the proxy parameters to allow outgoing traffic to be bypassed. Quick Fix While case-wise solutions are already provided in section above, here are some quick workarounds for immediate relief: Workaround 1: All the latest js agent files can be downloaded from the following cdn locations: 1. adrum-latest.js - here 2. adrum-ext.js - here 3. adrum-xd.html - here Workaround 2 : Download the adrum files zip folder from the Controller on a different machine/laptop that has internet connection and use that. Workaround 3: Download the files from your Controller using the " AppDynamics hosts all JavaScript Agent files from cdn.appdynamics.com" option. Steps 1-6 are below with screenshots attached for clarity: 1. Choose "AppDynamics hosts all JavaScript Agent files from cdn.appdynamics.com" Step1 2. Click on option 3. Save config and generate HTML snippet. Step2 3. Search for "scr" variable in the generated snippet. That will be the URL of your version specific adrum.js file. step3 4. Get adrum.js file: Open the URL copied at step 3 in a browser and save/download the resultant file as adrum.js. Step4 5. Get adrum-ext.js file: In your adrum.js file downloaded at step 4, search for "ext" and pick up the cdn URL for adrum-ext file. Open th e URL copied above in a browser and save/download the resultant file as adrum-ext.js. step5 6. Get adrum-xd.html : In your adrum.js file downloaded at step 4, search for "html" and pick up the cdn URL for adrum-xd file. Open the URL copied above in a browser and save/download the resultant file as adrum.js step6 Disclaimers 1. If you are using a SaaS Controller, you can download the latest version of files as mostly it will be on same major version. 2. If you have an On-Prem Controller or your version is not on the same major version as EUM SaaS, you need to download the files specific to your version, which can be done via the browser following workaround #3 given in the Quick Fix section. ________________________________________________________ Was this helpful?

Hi Paul, Our current Browser RUM metrics are based on a Pages & AJAX based approach. We don't typically have a CLICK event. That said, in your application code, you could basically generate a VirtualPage (start and end) events as part of the CLICK_handler and that would show up as a Virtual Page navigation within the EUM UI. Click Events are not explicitly monitored using the Javascript Agent unless they result in an AJAX call. However if making some custom changes is acceptable, you could intercept the clicks and report them as Custom Events using Javascript Agent APIs - https://docs.appdynamics.com/display/PRO45/Report+Events+with+the+JavaScript+API. However at the moment, clicks will not be monitored out-of-the box for BRUM applications. Thanks, Chitra

Hi Ramunas, This limitation is by design. For mobile apps we get only Country level location info. The location information for Mobile devices is found to be not very consistent, and hence it is not being reported by design. This is not a technical issue but more product philosophy. Mobile devices tend to have several proxy/NAT services between the device and our services. Because of this, devices can appear to be in different cities. We used to get many complaints about false information. Thank You, Chitra

Hi Prasanth, Your problem looks more related to using automatic injection than using transaction correlation. To verify this, (1) you can disable transaction correlation and enable automatic injection and verify if the problem with application access occurs or not? (2) Next enable transaction correlation and disable automatic injection and agian verify if the problem with application access occurs or not? If my guess is right you should see issue in test case 1 and not in test case 2. Let me know in case you observe otherwise. If so this mostly happens due to incorrect placement of the js agent. Refer to the below link for more info: https://docs.appdynamics.com/display/PRO45/Injection+Problems#InjectionProblems-FixPageRenderingIssues And verify if you have any <META> tags before your adrum script in the page source code. Thank You, Chitra

Hi Rashmi, This data isn't avialble by deafult; If you need, you can fetch the username for all the Real user transactions by collecting this info as custome user data and then this can then be seen in the page's browser snapshots. Refer to the belw doc link for more info and how to use this feature: https://docs.appdynamics.com/display/PRO45/Add+Custom+User+Data+to+a+Page+Browser+Snapshot Thank You, Chitra

Hi Anjana, We do not show this level of granulatity as of now, but its in the roadmap for future releases. As of now you can see all the pages that the user accesses, all resources that were loaded as part of that page, the touch events of that page for whatever options he accessed and post load events as you can see in the below image: Thank You, Chitra

Hi Harsh, Yes it should work with chrome. Though we do not have docs for the official support on this as of now, but we have seen it working for customers on chrome. FF I am not sure, but you can give a try. Thank You, Chitra

Hi Sangeetha, Please find answer to your queries below: Reg 1. No we can not omit certain api calls from a page, if you istrument any page with js agent, all the internal calls will be monitored. If those api calls are being made in a different page than the main page, then you can skip injecting the JS code in that second page to omit these calls, but not otherwise. Reg 2. What is the version of js agent that you are using? Ideally the End User Response Time (EURT) in modern browsers, those that support NavTiming, is calculated from the navigationStart to the loadEventEnd . Similarly, for older browsers, those which don't support NavTiming, the End User Response Time (PLT) is calculated from the writing of the starttime cookie on the previous page to the onload event. So for virtual pages, its more closely calculated as: var perfData = window.performance.timing; var pageLoadTime = perfData.loadEventEnd - perfData.navigationStart; Hope this clarifies. Let me know in case that does not help. Thank You, Chitra

Hi Ramesh, Could you please tell me what is ther version of controller and ios agent that you are using? ANR is generated when UI does not respond for 2 or more seconds, : https://docs.appdynamics.com/display/PRO45/Mobile+Sessions#MobileSessions-anr So if you are on version 4.5; we have an option to configure the ANR threashold, so you can try increasing it and see if that helps. But before that can you please share the entire crash file so that we can see what is the main thread crashing? Thank You, Chitra

Hi Harshvardhan Are you using IE browser? Because if so, Window popup monitoring is not supported for IE in synthetics. We currently do not support window.open() popups in IE which is why your script might be failing; Thank You, Chitra
