One of our colleagues, Dimitri, at the Paris Sun solution center has developed a real neat and useful tool called dim_STAT. To make it short it's a tool for both high-level and detailed, monitoring and performance analysis of Solaris and Linux systems.
Data is collected and saved in a MySQL database, and it provides a very functional web base user interface. It allows real time or off line monitoring, multi-host etc.
Actually what is really interesting with dim_STAT is that, when I'm benchmarking or tryinng to find a performance bottleneck, I can collect all the data I need and come back later for analysis.
Recently, Dimitri has added a new tool db_STRESS, that allows us
to put load on a database system and gives a high level metric
(TPS: Transactions per seconds) and therefor allows us to compare
how different systems compare together.
