Monitoring systems have a selection of objects that fit together. In order to monitor our server’s C:/ drive, we must first monitor our server. This is obvious. However sometimes the syntax and naming is very confusing, given that it often differs from vendor to vendor with some calling the server a “host” or a “monitor”, and some calling the C:/ drive style checks “monitors”, “service checks”, “counters”, etc. In the following paragraph, hopefully this syntax should become clearer as we step through each of the “3 layers”.
