Netdata will be part of the QualityBox dashboard.
== System Locations ==
<pre>
- the daemon at /usr/sbin/netdata
- config files in /etc/netdata
- web files in /usr/share/netdata
- plugins in /usr/libexec/netdata
- cache files in /var/cache/netdata
- db files in /var/lib/netdata
- log files in /var/log/netdata
- pid file at /var/run/netdata.pid
- logrotate file at /etc/logrotate.d/netdata
</pre>
== Host Modifications ==
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.
== Ports ==
netdata by default listens on all IPs on port 19999. We add a rule to firewalld to allow 20000 and then pass that port through to the backend in haproxy config.
<nowiki>http://this.machine.ip:20000/ => http://127.0.0.1:19999</nowiki>
== Start/Stop ==
To stop netdata run:
<code>systemctl stop netdata</code>
To start netdata run:
<code>systemctl start netdata</code>
