Working with Log Configurations

56.2.3 Working with Log Configurations

You can export the current settings for all listed logs as a configuration file, and reuse the settings on a later occasion by importing that file. Since the set of available logs is large, this function considerably eases the task of recreating a known log configuration for a Qualcomm device.

Log configurations can be referenced in a Log Configuration script activity for use during script execution, as detailed in section "Log Configuration". This activity also provides a number of predefined log configurations that you can import for specific testing scenarios. These configurations are described in section "Predefined Log Configurations".

If you are also interested in certain other important LTE information elements listed in section "Logs Required for Other Key LTE Elements", the easiest way to prepare your log configuration is to first turn off all LTE logs (Toggle All Logs and Events = "All Off"), then manually turn on the ones you require according to both section "Predefined Log Configurations" and section "Logs Required for Other Key LTE Elements".

Finally, section "Logs That Are By Default Disabled" covers a number of logs that are by default disabled. These must be actively turned on in order for their associated IEs and events to be obtained.

56.2.3.1. Exporting a Log Configuration

To export the current configuration:

Click the Import/Export Logmask button.

Select the Export option.

Under Export logmask settings to, enter a path or browse to where you want to store the configuration file, and name the file. It will take the extension .lcp.

56.2.3.2. Importing a Log Configuration

To import a previously exported configuration:

Click the Import/Export Logmask button.

Select the Import option.

Under Import logmask settings from, point to the configuration file you want to import.

56.2.3.3. Predefined Log Configurations

These are the ones available in the Log Configuration activity, described in section "Log Configuration". They are all intended for LTE network testing, and they modify only the set of LTE logs. All other logs (categories "Generic & CDMA", "GSM", "WCDMA", "UMTS", "Qualcomm IMS") are left as-is. No Qualcomm event reports are enabled in any of the predefined configurations.

Compared to the default LTE logmask, these configurations reduce the logfile size by a factor of 3 or thereabouts.

56.2.3.4. Logs Required for Other Key LTE Elements

The following LTE IEs are prime candidates for inclusion in a custom log configuration. Of course, the more selective the logmask, the smaller the resulting logfiles will be.
