[Udyan Saha Upal]

my another application is running on port 8080; so I tried to forward to the 8081 port but it showing this error. can anyone help? my port 8081 is free. I checked.
command:
pm2 logs 1 | logdy forward 8081
error:

INFO[20:22:24.905] Accept stdin and forward to port              port=8081

Hi @usUpal,
what are you trying to achieve? Logdy forward will forward all STDIN line to a specific port.
The error message panic: dial tcp :8081: connect: connection refused means that nothing is accepting a connection on port 8081.
You can start Logdy with logdy socket 8081, more here.

thanks for the quick reply @PeterOsinski . logdy's default port is 8080; what I am trying to achieve is run logdy in different port? can you pls tell me how can I do that?

[Peter]

The port 8080 is used to serve a UI, you can change it with --port option, for example:
logdy --port=8082
The setup you presented on a screenshot could be easily achieved with:
pm2 logs 1 | logdy --port=8082

If you'd like to stream multiple pm2 logs to logdy you can use tips from this blog post.
Let me know if that helps!

thanks, It worked. It wasn't an issue actually 😂
