Log Capture Scripts

To capture a failure scenario you can use the logcapture script. If you are running in a HA environment it maybe easier to stop AWMVS2 and MB2 and switch to a single AWMVS and single MB to reduce the amount log logs to collect, then run:

On Media Broker

/opt/avaya/awmvs/<version>/mvsdk/media_broker/logcapture.sh -c -p -f /tmp/<name_of_file>.tar

On Avaya Mobile Video Server

/opt/avaya/awmvs/<version>/awmvs/bin/logcapture.sh -c -p -f /tmp/<name_of_file>.tar

After starting the above log capture, repeat the failure scenario, stop the log captures with Ctrl-C command and then send the resulting tar files to Support.

Note : Files may be too big to attach to an email or ticket (20 MB limit on Zendesk) so can be made available to us via the cloud or we can provide you with an upload link for our file server (please ask us on the ticket).

Manual Server Log Retrieval

If for whatever reason the scripts are not appropriate, for example you want to look at some logs yourself or the issue is related to server startup issues then below lists useful log locations:

MVS

/opt/avaya/awmvs/3.0.1/awmvs/domain/logs

/opt/avaya/awmvs/3.0.1/awmvs/domain/servers/appserver-<Hostname>/log

/opt/avaya/awmvs/3.0.1/awmvs/domain/servers/loadbalancer-<Hostname>/log

/opt/avaya/awmvs/3.0.1/awmvs/domain/servers/management/log

/opt/avaya/awmvs/2.0.10/awmvs/domain/servers/appserver-smvivaldi/log/traffic.log 

MB

/opt/avaya/awmvs/3.0.1/mvsdk/media_broker/

/opt/avaya/awmvs/3.0.1/mvsdk/media_broker/rtp-proxy-instances/mb-0

/opt/avaya/awmvs/3.0.1/mvsdk/media_broker/rtp-proxy-instances/mb-1

/opt/avaya/awmvs/3.0.1/mvsdk/media_broker/rtp-proxy-instances/mb-2

/opt/avaya/awmvs/3.0.1/mvsdk/media_broker/rtp-proxy-instances/mb-3

/opt/avaya/awmvs/3.0.1/mvsdk/media_broker/rtp-proxy-instances/mb-4 

If the service has been restarted you may be requested to tar up the log directories as archives so we can check through historical data.

Here's an example of the commands you would need:

/opt/avaya/awmvs/3.0.1/awmvs/domain/ #tar cvfz mvs-domain-logs.tar.gz log/

/opt/avaya/awmvs/3.0.1/awmvs/domain/servers/appserver-<Hostname>/ #tar cvfz mvs-server-logs.tar.gz log/

Which will produce:

/opt/avaya/awmvs/3.0.1/awmvs/domain/mvs-domain-logs.tar.gz

/opt/cisco/<version>/awmvs/domain/servers/appserver-<host>/mvs-server-logs.tar.gz 

Getting MVSDK Configuration

Providing the configuration for the cluster is also normally needed along with logs. The easiest way to provide this is to navigate to

https://<mvs_address>:8443/admin/gateway/1.0/configuration  

You need to provide the MVSDK web_plugin_framework credentials. Then copy and paste the contents of the page into a text file, save it in .xml format and attach it to the ticket.

Note: Please don't use MS notepad as it corrupts the formatting of the page

Client Logs

Before obtaining browsers logs (sometimes also referred to as console/client logs) from Chrome or Firefox, could you please follow the instructions below to ensure that timestamps are enabled on your browser, these can be very useful to us when attempting to resolve an issue.

Enabling timestamps:

Applies to both Chrome and Firefox: Press F12 on your browser and select the "cog" settings button as highlighted in the the screenshot below, you will then see the menu illustrated below, ensure that the highlighted boxes are ticked.

Chrome: If using Chrome for a client then you can see the logs in the console, shown by bringing up the page context menu (normally by right clicking in the browser window) and selecting "Inspect Element", and then selecting the Console tab. These logs are normally detailed enough for us.

Note: Once the test is complete right click anywhere in the console window and select  "save as" to save the logs to file.

On some occasions we need more detailed logs that are obtained by opening a new instance of chrome in debug mode as follows:

Windows: <Chrome Directory>\chrome.exe --enable-logging --v=9 --vmodule=*libjingle/source/*=9 --user-data-dir=c:\chromedebug

Mac: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome    --enable-logging --v=9 --vmodule=*libjingle/source/*=9 --user-data-dir=/User/<your user dir>/chromedebug

• Firefox: Firefox console logs are accessed in a similar way to Chrome above. Right click within the firefox window and either select "Inspect Element" or after the right click just press Q. Once the window has appeared there will be a "Console" tab, the logs found here are again normally detailed enough for us.  
• Internet Explorer: IE works the same as Firefox above without the shortcut of Q. To access the logs from IE simply right click, then click "Inspect Element". This will then bring up a set of windows, just click the "Console" tab. These logs should contain enough information for us to diagnose. 

How to obtain the Browser Console Logs

1. Right click in your browser window, left click 'inspect' or 'inspect element'. This will bring up the developer tools

2. Click on the console tab

3. Recreate the issue you are seeing.

4. To save: Each console varies from browser to browser but generally you can: Right click (inside the console tab window) > Save as (notepad text file). Or Right Click > Select All, Right click > Copy. Then you'll want to paste that into a text file.

5. These text files tend to be small so you will be able to attach it directly to the ticket.

Collecting HAR network logs

The HTTP Archive format or HAR, is a JSON-formatted archive file format for logging of a web browser's interaction with a site.

7. Recreate the issue you are seeing.
8. Once you have reproduced the issue, right click anywhere on the grid of network requests, select Save as HAR with Content , and save the file to your computer.
    

How to generate a HAR on Microsoft Edge

• Android: There are a number of ways to obtain logs from an Android device.

1. In the lab if using Android Studio use this guide https://developer.android.com/studio/debug/am-logcat.html
2. If you use Eclipse then this tutorial will help https://www.utest.com/courses/android-debug-bridge-part-1-how-to-capture-logcat-files-using-adb (sign in required)
3. Note: From Android 4.1 onwards installing a Log capture app onto the device will only give you access to the apps own logs unless the device is rooted.
