I received a request to monitor EHLO reponses from various Exchange CAS servers. My initial thought was to use a SiteScope port monitor, point it to the SMTP port, and use the "Send String" field to issue a "ehlo <domainname>.com" request. However, I discovered that this wouldn't provide what the customer needed, as the monitor only has threshold conditions for status, round-trip time, and initial port response (i.e. there is no way to check against a response from whatever I issue via the "Send String" field).
So, I would appreciate any advice on how I might be able to meet this requirement. Is there a way to tweak the port monitor to do what I need, or can you suggest a different SiS monitor type to use?
