How can I monitor CPU,HTTP,SQL request on a node?

Hi,

 

 

I'm looking for a way to monitor CPU, HTTP, FTP ,SQL requests on a node or a specific pool member and get extended informations like response time, success or fail, CPU usage, SQL state, ...

 

 

I will need it to design my own dynamic load-balancing algorithm.

 

 

I know we can use specific monitor which trigger on this "settings" but we can't pull extended informations, it is just a green or red light for up or down.

 

 

Thanks for your help

    Maybe use a seperate program to pull information via SNMP and then use ratio load balancing. You can use iControl to change the ratios, if that's what your looking for as dynamic load-balancing.

    Have you tried the stuff by cuddletech? http://www.cuddletech.com/articles/snmp/node1.html

     

     

    I've never used it but know a guy who says it's great. He's not doing iControl, but that shouldn't matter since the SNMP stuff is separate.
