I have been unable to find any information on PRTG agents, including where to download them. The PRTG videos seem to imply that the only way to monitor things is either WMI or SNMP. That implies that if we need to monitor things that are not accessible by default via WMI or SNMP we have to figure out some way to do so. For example, we are software developers and our solutions are use components such web servers, databases, various middle-ware and so forth. These do not usually come with the ability to monitor them using either WMI or SNMP. What do people do in such cases or is PRTG really not intended for that?
