To ensure that metric information that is most relevant to your application displays, agents have limits for the number of metrics they can store. Different limits apply to app agents and machine agents:

• For an app agent, the default maximum number of registered metrics is 5000.

• For the Machine Agent, the default maximum number of registered metrics is 450. This includes both basic hardware metrics and the expanded metrics available with Server Visibility.

If the limit is reached, an error event is generated of type AGENT_METRIC_REG_LIMIT_REACHED with a summary of Metric registration limit of n reached. No new metrics are created until the agent restarts. If necessary, you can increase the default limit.
