Question Scheduled task - save output to file?

[antduz]

Server operating system version

OS: CentOS Linux 7.9.2009 (Core)

Plesk version and microupdate number

Plesk Obsidian 18.0.50 Update #2

I have a scheduled task in Plesk (a command-line PHP script) that executes every minute but occasionally fails to execute without sending anything to the email address specified in Plesk to receive error logs.
It's not practical to send emails on every run because it runs every minute and any errors will be buried in that pile of emails.
Is there any way to save the stdout of the script to the server file system?
I don't have root rights on this server to edit crontab manually. But I can view the crontab file where I see that all Plesk tasks redirect to /dev/null, e.g.

* * * * * (/usr/bin/php -f 'httpdocs/scheduler.php' -- '-h' 'censored.ch') > /dev/null
SHELL="/bin/sh"
MAILTO="em@censored.ch"

Couldn't you update the PHP script to create the logfile itself? I would think that would be the better solution if you don't have root access to the server to edit the crontab manually.

I could, but due to the nature of this script I want to run it from CLI as well, which means writing to stdout.

That doesn't count , because when the script itself writes the log, there is no need for it to write to stdout by the system function.
