Output

Timestamps

--timestamps puts the time before each line the command writes, on the standard and the error output:

bin/console app:import --timestamps
bin/console app:import --timestamps=relative

[2026-03-14T09:26:53.589+00:00] Importing 1200 rows
[+12.345s] Imported

The time is added to the bytes written to the stream, after the formatter has done its work:

• a line written in several parts gets one time, at its start;
• the widths of tables, titles and blocks stay those of their text;
• a message the verbosity hides never reaches the stream, and gets no time;
• the time is grey on a decorated output, plain otherwise.

An output that writes to no stream, such as a BufferedOutput, gets no time. The guards' question and notice come before the timestamps are attached, and have none.

Debug logs

With Monolog, --debug-phil writes the logs of chosen channels, from the debug level up, to the error output, whatever the verbosity of the handlers the application configures:

bin/console app:import --debug-phil=doctrine,http_client
bin/console app:import --debug-phil

Without a value, the option prints the channels of debug.channels, or every channel when that list is empty. The channels are those of MonologBundle: app for monolog.logger, and the name of each monolog.logger.<channel>. A channel the container does not have is reported on the error output; the others are printed. The messages are written as raw text, never read as console markup. The handlers are taken off the loggers when the command ends.

Summary

At the end of a command, with -v by default, the error output gets one line:

app:import: exit code 0 in 12.345 s, memory +3.2 MiB, peak 48.0 MiB.

The duration runs from the end of the guards to the end of the command; the memory is what PHP's scripts use more, or less, than at the start; the peak is the process's, since it started. summary: always writes the line at every verbosity, summary: never never.

The options of a command

The three options are added to the command that runs, not to the application: an application option would clash with a command that defines an option of the same name its own way. Such an option stays the command's, and the bundle leaves it alone; timestamps.enabled still applies to it.
