Hi, I'm using a free edition of App. Manager version 6 build number 6056, I defined 5 monitors: 1 for URL, 2 for weblogic servers 8.1 sp 5 on Linux and last one for Oracle 9.2 on Linux. App. Manager machine is Win XP sp2. It happens to me always that each second alert is in "red status" (either response time is very long or by App. Manager all servers are down), apparently it is not true. I set checking interval for all monitors to 1 minute, on the App. Manager machine is running antivirus.
