dmsg

Note

dmsg-server needs to be run on a public IP.

Hardware Requirements

• It is recommended for server to have minimum RAM of 2GB, if the connections go above 2500, RAM should be increased appropriately.
• fs.inotify.max_user_watches needs to be set relatively high.

To check fs.inotify.max_user_watches value, run:

cat /proc/sys/fs/inotify/max_user_watches

To set fs.inotify.max_user_watches value, run:

sudo sysctl -w fs.inotify.max_user_watches=<value>
