Netdata doesn’t have a centralized configuration. All nodes need to be configured separately. If I need Notifications to Telegram or another channel, I need to configure all nodes separately.
For monitoring SNMP devices I need to install a Netdata instance with configured SNMP collector?
Correct. You will then get an “snmp” node under the overview for that node.
So you don’t need a node dedicated to SNMP collection as it’s just parasitic on the node.
