Settings in the LightAgent.conf file

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.
• 600 ("Important"): important messages.
• 700 ("Information"): informational messages.
• 800 ("Debug"): debug messages used by developers.
• 900 ("Paranoiac"): debug messages with more detailed information used by developers.

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.

This section contains processing and rotation settings for Light Agent for Linux main trace file (LightAgent.log).

period = 3

File rotation frequency.

Possible values: 1 – monthly, 2 – weekly, 3 – daily, 4 – hourly.

max_file_size = 1073741824

Possible values: 0 – unlimited, 1073741824 – 1 GB.

max_file_count = 25

The maximum number of the trace files. When the limit is reached, old files are deleted.

Possible values: number or 0 – unlimited.

new_file_on_start = 1

Logging to a new file or to the last available trace file when the application starts.

Possible values: 1 – write to a new file, 0 – write to the last created file.

This section contains the system log usage settings.

enabled = 0

System log usage. Possible values: 1 – enable, 0 – disable.

format = %I %p:

Syslog entry format: %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.

This section contains dump file settings for Light Agent for Linux.

dir = /var/opt/kaspersky/lightagent/dumps

schema = LightAgent_%d_%p_%n.dmp

Name configuration:

• %d – date and time (for example, 08.27_19.39);
• %p – process ID;
• %n – dump number in the session.

max = 4

The maximum number of dumps in the repository.

freeMiB = 1024
