Logging tool commands.

Usage

log [OPTION]

log list

Lists all processes/components registered with the log daemon.

log level

Sets the log filter level. Log messages that are less severe than the filter are ignored. Must be one of EMERGENCY | CRITICAL | ERROR | WARNING | DEBUG.

log trace

Enables a trace by keyword. Any traces with a matching keyword is logged. The KEYWORD_STR is a trace keyword.

log stoptrace

Disables a trace keyword. Any traces with this keyword is not logged. The KEYWORD_STR is a trace keyword.

Forgets all settings for processes for the specified name.

log help

Options

[DESTINATION]

Optional, specifies the process and component where to send the command.

The [DESTINATION] must be in this format:

process/componentName

'process' can be a processName or a PID. If it's a processName, the command will apply to all processes with the same name. If it's a PID, it only apply to the process with the matching PID.

Both the 'process' and the 'componentName' can be replaced with an asterix ("*)" to mean all processes and/or all components.

If the [DESTINATION] is omitted, a default destination is used and applies to all processes and all components:

"*/*"

The [in] preceding the [DESTINATION] is optional and may be omitted.

A command can be sent to a process/component that doesn't exist yet. It'll be saved and applied to the process/component when available. This way, you can pre-configure processes/components before they are spawned, but it's only valid if the [DESTINATION] is a process name. Otherwise, the 'process' will be dropped."
