Use these guidelines to identify memory usage problems:

• The Node.js Agent attempts to report once per minute, but on a heavily loaded, memory-saturated application it could be less often.
• It is normal for the controller to display 0 for the Current Instance Count and Shallow Size between instance count collection times.
• Hover over a peak in the graph to display information about the instance count.
• Look for trends where the peaks increase in size from left to right. These may indicate a memory leak.
