Settings in the LightAgent.conf file
The LightAgent.conf file contains Light Agent for Linux operation settings. The file is located on the protected virtual machine in the /etc/opt/kaspersky/lightagent/ directory.
Root account permissions are required to view and modify the file.
This section describes the settings in the LightAgent.conf file that allow you to configure logging of Light Agent for Linux traces and dumps and usage of Light Agent for Linux system log. Information about other settings, if necessary, can be obtained from the Technical Support.
Unassisted modification of the application operation settings in the ways not described in the application help or in the recommendations from the Technical Support specialists can lead to slowdowns and malfunctions of the operating system, decrease of the virtual machine protection level, as well as to a violation of the availability and integrity of the processed information.

General settings
trace_level = 0
Determines the trace level for all Light Agent for Linux trace files except the avp-cli.log file.
Possible values:
- 0 – creation of trace files is disabled.
- 100: "Always" – informational messages about application components being started and stopped.
- 200: "Critical" – messages about critical errors, which can result in the application termination.
- 300: "Error" – messages about errors, which can result in partial inoperability of the application.
- 400: "Danger" – warnings about the possibility of critical errors.
- 500: "Warning" – warnings about possible errors.

After changing the trace level, restart the lightagent service by running the following command:
systemctl reload lightagent
trace_file = /var/log/kaspersky/lightagent/LightAgent.log
Name of the main Light Agent for Linux trace file. The date is appended to the file name, for example, LightAgent.2020-11-30T094058.log. The rotation settings are controlled by the lightagent service.
The trace file is used if system log usage is disabled (see section [syslog]).
trace_format = %Y-%m-%dT%X %I %p:
The format for logging lines in the main Light Agent for Linux trace file.
Qualifiers: %Y = year, %m = month, %d = day, %H = hour, %M = minute, %S = second, %i = millisecond, %p = trace level, %N = device name, %P = process identifier (PID), %I = thread ID, %C = component ID, %D = component instance ID, %X = time.
The trace file is used if system log usage is disabled.
[rotation_settings] section
This section contains processing and rotation settings for Light Agent for Linux main trace file (LightAgent.log).
