Once per minute Can you run multiple endpoints in a single ActiveGate plugin module? Yes What kind of ActiveGate executes ActiveGate plugins? Environment ActiveGate Can you execute ActiveGate plugins using an Environment ActiveGate that's configured for multi-environment support? No Where can you view results from plugin-monitoring? Technology overview page What is a "device group"? A technology tile that derives its data from an ActiveGate plugin. Why would you set up "key metrics" for an ActiveGate plugin? Define important metrics to be displayed in technology overview page. What is the favicon property in the definition? Allows you to define your own custom icon for device groups! What can device groups represent? Clusters, regions, groups of servers, etc. What is a custom device group entity? Bind metrics and properties to monitor device group metrics How do you define the type and look of charts of ActiveGate plugins? What is pgmetrics in for ActiveGate plugins? Section that allows you to define custom device metrics. Does Dynatrace AI baseline the metrics of your custom devices? Yes! How does Dynatrace create problems from custom devices (ActiveGate plugin)? Metric threshold violation in JSON definition. (Automatically sends events, not problems) How do you manually generate problems for your ActiveGate plugins? Python API - raise performance, availability, error, and resource contention problems Does Dynatrace automatically distribute plugins between Dynatrace server and ActiveGates? No, you need to deploy them on ActiveGate and upload them to server. In general, what is the point of (ActiveGate plugins)? Define how data is presented in the Dynatrace UI. In general, what is the point of Python files for ActiveGate plugins? Define additional events, create custom properties. How many Cluster Management Consoles are there per cluster? One per cluster.
