Everyone thankyou for your responses. I am trying out the tools one by one.
It would be great to get recommended on some tool tried and tested. I need monitoring and management. Essentially now, during my development cycle. Later I may need more monitoring and lesser management. My scenario is simple - read my entire db, populate the cache with all records - as records are written, i add into the cache - as requests come i read the cache, if i get nothing, i read the db and populate the cache (to enable subsequent good reads from cache requests) So I need the following - debug what I have populated from the entire db, clean up cache command - debug writes - debug reads - statistics in general - configure the cache, add more servers, reset servers I need something that works, cacti thing is just not populating the "Current Items" graph. I dont want to use something experimental, dont have the time to try everything. I am wondering if anyone of you have the tools installed, please advice me on stability, reliability of the tool. I installed cacti and top. Cacti is not reliable. Top is kinda good. Simple and gives kinda dashboard feel. Cacti does not have any forum support too. Questions dont get answered, I guess its not as famous, or may be it still under development. Please advice on trial and tested.
