In Tiers & Nodes, select a tier or node and click Details. The tier and node dashboards contain a flow map view at the tier or node level, including widgets for health statuses, load time, response time, and errors. The Memory tab shows memory information relevant to your application environment. Note that the specific information shown for each environment can vary, depending on the environment. PHP memory management is different than other languages. The relevant memory metrics supplied by the App Agent for PHP are in the Metric Browser.
