--- Check KSM (kernel memory deduper) ---

Memory de-duplication instructions

You have kernel memory de-duper (called Kernel Same-page Merging,
or KSM) available, but it is not currently enabled.

To enable it run:

echo 1 >/sys/kernel/mm/ksm/run
echo 1000 >/sys/kernel/mm/ksm/sleep_millisecs

If you enable it, you will save 40-60% of netdata memory.

--- Check version.txt ---
--- Check apps.plugin ---
--- Copy uninstaller ---
--- Basic netdata instructions ---

netdata by default listens on all IPs on port 19999,
so you can access it with:

To stop netdata run:



To start netdata run:

systemctl start netdata

Uninstall script copied to: /usr/libexec/netdata/netdata-uninstaller.sh

--- Installing (but not enabling) the netdata updater tool ---
Update script is located at /usr/libexec/netdata/netdata-updater.sh

--- Check if we must enable/disable the netdata updater tool ---
Adding to cron
Auto-updating has been enabled. Updater script linked to: /etc/cron.daily/netdata-updater

netdata-updater.sh works from cron. It will trigger an email from cron
