# Insights Diagnostics

The **Diagnostics** tab displays the metadata of the agents that are running and sending traffic for a service. Visit this page if you're not sure if the Insights Agent is connected, or if you want to check that the agent is seeing all of your traffic. You can also install new agents from this tab.

Expand an endpoint to display details about your traffic and diagnose related issues.
