Open a new terminal and navigate to the netdata.conf file. Use the edit-config script to make changes: sudo ./edit-config netdata.conf
The most popular settings to change are:
Increase metrics retention (4GiB)
sudo ./edit-config netdata.conf
[global]
dbengine multihost disk space = 4096
Reduce the collection frequency (every 5 seconds)
sudo ./edit-config netdata.conf
[global]
update every = 5
Enable/disable plugins (groups of collectors)
sudo ./edit-config netdata.conf
[plugins]
go.d = yes # enabled
node.d = no # disabled
Enable/disable specific collectors
sudo ./edit-config go.d.conf
Or python.d.conf, node.d.conf, edbpf.conf, and so on
.
modules:
activemq: no # disabled
bind: no # disabled
cockroachdb: yes # enabled

$ sudo ./edit-config go.d/mysql.conf
$ sudo ./edit-config ebpf.conf
$ sudo ./edit-config python.d/anomalies.conf
Configuration

Understanding the dashboard
Charts: A visualization displaying one or more collected/calculated metrics in a time series. Charts are generated by collectors.
Dimensions: Any value shown on a chart, which can be raw or calculated values, such as percentages, averages, minimums, maximums, and more.
Families: One instance of a monitored hardware or software resource that needs to be monitored and displayed separately from similar instances. Example, disks named sda, sdb, sdc, and so on.
Contexts: A grouping of charts based on the types of metrics collected and visualized. disk.io, disk.ops, and disk.backlog are all contexts.
