We tried even Nagios but still we need to go for our custom script which will best suit for our needs..
My first thought is you have failed miserably to communicate what your needs are. I can't for the life of me imagine any real world need that Nagios can't be coerced into fitting and I've seen a few that defy the term "real world"™. In one shop I worked at someone had rigged a sensor, interfaced it to a serial port on a Linux box and using nrpe sent pages to the support team when the level in the coffee pot got too low. If that could work you would have to work really hard to find a monitoring requirement that some effort and creativity won't solve.
In fact, I'm starting to think you just might be a troll.
Usually when I see someone ask a question, a bunch of folks offer solutions and the asker still says "That won't work" without saying specifically why I start thinking they just want validation that they cannot find a solution.
Didn't start out write a rant, but I did...
