Others are discussing the performance/tuning stuff, but can I make one suggestion? Don't log your monitoring info directly into the database, log straight to one or more text-files and sync them every few seconds. Rotate the files once a minute (or whatever seems suitable). Then have a separate process that reads "old" files and processes them into the database. The big advantage - you can take the database down for a short period and the monitoring goes on. Useful for those small maintenance tasks. -- Richard Huxton ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
