### Logging
|
||||
|
||||
The following logging-related flags are inherited from the
|
||||
[klog](https://pkg.go.dev/k8s.io/klog/v2) package.
|
||||
|
||||
#### -add_dir_header
|
||||
|
||||
If true, adds the file directory to the header of the log messages.
|
||||
|
||||
Default: false
|
||||
|
||||
#### -alsologtostderr
|
||||
|
||||
Log to standard error as well as files.
|
||||
|
||||
Default: false
|
||||
|
||||
#### -log_backtrace_at
|
||||
|
||||
When logging hits line file:N, emit a stack trace.
|
||||
|
||||
Default: *empty*
|
||||
|
||||
#### -log_dir
|
||||
|
||||
If non-empty, write log files in this directory.
|
||||
|
||||
Default: *empty*
|
||||
|
||||
#### -log_file
|
||||
|
||||
If non-empty, use this log file.
|
||||
|
||||
Default: *empty*
|
||||
|
||||
#### -log_file_max_size
|
||||
|
||||
Defines the maximum size a log file can grow to. Unit is megabytes. If the
|
||||
value is 0, the maximum file size is unlimited.
|
||||
|
||||
Default: 1800
|
||||
|
||||
#### -logtostderr
|
||||
|
||||
Log to standard error instead of files
|
||||
|
||||
Default: true
|
||||
|
||||
#### -skip_headers
|
||||
|
||||
If true, avoid header prefixes in the log messages.
|
||||
|
||||
Default: false
|
||||
|
||||
#### -skip_log_headers
|
||||
|
||||
If true, avoid headers when opening log files.
|
||||
|
||||
Default: false
|
||||
|
||||
#### -stderrthreshold
|
||||
|
||||
Logs at or above this threshold go to stderr.
|
||||
|
||||
Default: 2
|
||||
|
||||
#### -v
|
||||
|
||||
Number for the log level verbosity.
|
||||
|
||||
Default: 0
|
||||
|
||||
#### -vmodule
|
||||
|
||||
Comma-separated list of `pattern=N` settings for file-filtered logging.
|
||||
|
||||
Default: *empty*
