We recently installed a web server agent for apache. We noticed that on different days the "started time" on the agent overview dashlet for the web server agent (not the web service agent) changes. I always believed this would mean the last time the process was restarted. However, the PID for the web server (apache) always remains the same and the application owner says there was no restart. Could someone help explain to me why this might occur so that the app owner will feel comfortable enough to instrument their production with appmon. Thanks!
Note: We actually installed the web server agent on two apache. And on both hosts this activity is occurring.
