I know Slack only from hearsay, but a CPAN search finds e.g. Log::Dispatch::Slack, "Send log messages to Slack". Hasn't been updated in several years, but testers are all green, so from my outside view, it looks "rock bottom stable" ;-)
Comment on Re: Before I reinvent the wheel .. is there a Log4perl appender for Slack?
For a long time, I had a link in my .sig going to Groklaw. I heard that as of December 2024, this link is dead. Still, thanks to PJ for all your work, we owe you so much. RIP Groklaw -- 2003 to 2013.
