Top Tab

The Top tab gives you access to Netdata Functions that can be executed on any node running the Netdata Agent. These specialized routines, provided by various collectors, offer enhanced insights and allow you to trigger specific actions directly on the monitored node.

You can use these Functions to:

• Retrieve extra diagnostic information
• Perform actions to support troubleshooting directly on the node

tip

You can also execute a Function from the Nodes tab by pressing the f(x) button next to the node.

note

If you receive an error saying that your node can’t execute Functions, check the prerequisites to ensure your node is configured properly.
