Tagging messages in syslog

[Draghmar]

Hi. Is there a way to tag message sent by Swoole that goes to journal? With php-fpm I can set syslog.ident to something I like and it will be set this way when viewing in journal. I tried that with Swoole but it looks like this setting is not taken into account. I was able to force it somehow. But not entirely. Using error_log does use my tag but when I'm getting warning it's tagged with default php.

Update to the issue.
I first noticed that when I was looking through the Swoole HTTP server logs and found "header already sent" type of warnings. It wasn't tagged with my custom tag but with the default one. So it looks like this kind of message was sent somehow outside of Swoole jurisdiction. Is there a way to prevent that? The warning itself came from message about some deprecated stuff, which is weird because it looked like it manage to prevent proper response.
