on aix; I pretty much use native tools (vmstat, iostat & topas) for server resource monitoring. I have scheduled a cron job to have nmon capture server resource utilization at 5 minute intervals. This data can be used with nmon-analyzer to generate graphs. On days where performance issues are reported; nmon graphs is a good thing to share with the team for cpu, memory, paging and network. Most of my IBM hardware runs virtual machines. While nmon is mostly used to get the server resource utilization for any given day; ganglia is good tool that gives graphs over a week, month and year. Also ganglia is good for virtualized/clustered environments as there are graphs that stack up the resource utilization of all the virtual machines/nodes. This helps us to quickly determine if there is capacity to host more virtual machines or not. For a clustered environment it helps to determine if the load is evenly distributed and if all the available resources of a cluster are maxed out or not.
