Not sure if anyone else has run into this issue, but I thought I'de post it on the forums. We are currently on SAM v5.5 and are monitoring our web sites using the HTTP Monitor. One of the configurable options for this component monitor is the "Head Request," in which your options are "Request Head Only" or "Full Request." As we found out after some product detail pages were coming up as OOPs pages ( and confirmed by Orion Support ), "Request Head Only" does not actually request the HTML header. If you set the component monitor to debugging mode and watch the logs it generates, it is looking for status codes. If your webpage loads (200), the status is green. The "Request Head Only" does not use the Search String criteria ( to my knowledge) at all.
If anyone is looking to perform a web site page check using these monitors, it is suggested to use the "Full Request" with a search string.
I felt that this was misleading and I hope this gets fixed in a future release. "Request Head Only" should at the very least have the metadata from the HTML header in the request. Hopefully this can help someone else before they run into issues. ,
