Netdata will be part of the QualityBox dashboard.
See http://freephile.qualitybox.us:20000/
System Locations[edit | edit source]
- 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
Host Modifications[edit | edit source]
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[edit | edit source]
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.
http://this.machine.ip:20000/ => http://127.0.0.1:19999
Start/Stop[edit | edit source]
To stop netdata run:
systemctl stop netdata
To start netdata run:
systemctl start netdata
