cat /proc/sys/fs/inotify/max_user_watches
Update /etc/sysctl.conf to increase the value (add or change the entry):
fs.inotify.max_user_watches=65536
Since the new values have to be in effect for the services before they start the easiest thing to do is reboot and check the value again after reboot.
Keep in mind that the inotify watchers are monitoring directories so the limit would be tied to the number of subdirectories in your
