Dima & Val, My first intention was to store metrics locally and collect them on demand.
But after that I start to think about following scenarios: What if we have a grid with clients that connected to grid, execute some query and *disconnected*? In this case we would have no option to collect metrics about what queries were executed on grid. Also, very often clients may resided in a *slow* network segment and sending a task for collecting metrics from *fast server nodes* and *slow clients* may take a lot of time in case of large grid. Could you suggest me how I could deal with two mentioned above cases? Or we could ignore them for now? -- Alexey Kuznetsov
