I have corporate 3 level (client -app server -DBserver) COM appication. Sometimes it down. Restart COM service dont help. 1 way it restart server. I dont now how monitor it.
Please give me a way how I can monitor COM application server.
COM service on app server dont stop so I cant check service.
May be I need use TCP/UDP test. So I need to sniffer traffic from client application and than check for reply.
How your experience in monitoring COM app server.

You can use TCP test if your COM application is designed to listen for incoming traffic on some specific TCP port and it can accept some simple requests so you may setup string (packet) for the test.

Otherwise I think you may use Shell Script test method and some VBScript. Your script can create object using WScript.CreateObject method and call any method supported by your COM object.
