A Server log keeps a record of all Server transactions in basic text form, while a Desktop Client log keeps a record of all client interactions. In certain cases to speed up and simplify a troubleshooting process, you might be asked to provide us with Server or Desktop Client logs.

Note: Use the toggle to collapse ▼ or expand ▶ the instructions for your desired OS. 

How to change Server logging level

Note: DEBUG and VERBOSE log levels might cause extra resource usage increase. Always consider changing the settings below back to the default state. 

You can modify the level via the web admin or configuration file.

Web Admin

To change the log level through the Web Admin interface:

  1. Navigate to the Web Admin interface and log in with Administrator level credentials.
  2. Click on the appropriate Server under the Servers section.
  3. Open the hidden "Advanced" section of the Web Admin interface by appending ?advanced=true to end of the URL.
    For example:
    https://127.0.0.1:7001/#/settings/servers/726a51c4-d15e-34d9-c394-19b7bcf9402e?advanced=true
  4. Once you are in the Advanced view, go to the Log Settings section.
  5. Locate the MAIN log level drop-down menu and choose the option as instructed by our support team (usually it will be Debug: Log every System message and debug information).
  6. Click Save.

Server Configuration File

You can change the log level through a Windows Registry file or a Linux configuration file. 

Windows
  1. To increase logging level open the registry editor (win key + R -> regedit -> enter) and navigate to 
    HKEY_LOCAL_MACHINE\SOFTWARE\Network Optix\Network Optix Media Server
  2. Add the logLevel string, and set the desired value (e.g., DEBUG). Click OK to save.
  3. Restart the Media Server to apply changes
  4. Server logs will be available at 
    C:\Windows\System32\config\systemprofile\AppData\Local\Network Optix\Network Optix Media Server\log
Ubuntu
  1. To change the log level, open vi editor and modify the server config file: 
    /opt/networkoptix/mediaserver/etc/mediaserver.conf
  2. Add logLevel string, and set the desired value (e.g., DEBUG2). Save the modified file.
  3. Restart the Media Server to apply changes
  4. Application logs will be available at 
    /opt/networkoptix/mediaserver/var/log
