+ You have kernel memory de-duper (called Kernel Same-page Merging,
or KSM) available, but it is not currently enabled.
To enable it run:
sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
- These commands allow apps.plugin to run as root.

apps.plugin is performing a hard-coded function of data collection for all
running processes. It cannot be instructed from the netdata daemon to perform
any task, so it is pretty safe to do this.
