-# VPP Logging Configuration
-
-VPP logging is an important part of monitoring and troubleshooting
-the performance and behavior of the VPP dataplane.
-
-VPP stores logs in two places:
-- `/var/log/vpp.log` — This file contains logs related to daemon
- startup and logs of commands executed directly via VPP CLI. Pay
- attention: VyOS does not use VPP CLI for configuration, so this log
- will not contain any configuration changes made via VyOS CLI and will
- not be informative in most cases.
-- System journal — contains logs related to the VPP daemon work,
- including errors, warnings, and informational messages. It is the
- main destination of logs generated by VPP.
-
-Logging detail level can be configured via the next command:
-
-```{cfgcmd} set vpp settings logging default-level \<level\>
-```
-
-Where `<level>` can be one of the following:
-
-- `emerg` (Emergency) - System is unusable.
-- `alert` (Alert) - Immediate action required.
-- `crit` (Critical) - Critical conditions.
-- `error` (Error) - Error conditions.
-- `warn` (Warning) - Warning conditions.
-- `notice` (Notice) - Normal but significant.
-- `info` (Informational) - Routine informational messages.
-- `debug` (Debug) - Detailed debugging messages.
-- `disabled` (Disabled) - Logging disabled.
-
-It is recommended to set logging level to `debug` only for
-troubleshooting purposes, as it can generate a large volume of log
-data. For regular operation, a level of `info` or `warn` is usually
-sufficient.
-
-## Troubleshooting
-
-Improper logging configuration can lead to various issues, including:
-
-- Excessive log file sizes if the logging level is set too high
- (for example, `debug`).
-- Missing critical information if the logging level is set too low
- (for example, `alert`).
-- Performance degradation due to excessive logging overhead
-
-Consider adjusting the logging level if you experience issues mentioned
-above.
