With each monitoring cycle– an interval that you specify, such as every 6 minutes– VitalSigns will use the Notes client DLLs to connect to the server just like any other user. From the perspective of the server, VitalSigns is a Notes client. In this way VitalSigns can independently confirm what users most care about—is this Domino server responding to Notes client requests? VitalSigns times how long it takes from the request to the response, and compares that with the threshold you set to determine if the server is getting slow.
Once VitalSigns determines that a server is responding, it records the response time and compares that against a threshold. It records the amount of minutes since the last scan as “up time” for calculating availability statistics. If the server were not responding, it would begin to record down time.
Assuming the server is up, VitalSigns then sends a series of statistic requests and uses the results to check the server’s memory, disk space, and other potential sources of trouble.
You can configure Domino servers for monitoring by selecting Servers & Devices, Lotus Domino, Servers, as shown in Figure 1 below:
Each Domino server has an associated “Properties Box” with which you configure the scanning interval, response and mail thresholds, and other settings such as server tasks and maintenance windows. A maintenance window is a scheduled period during which you do not want the server monitored, for whatever reason.
