Good Morning list , We have our production databases ( most 11.2.0.2 RAC on Solaris 10) pro -actively monitored by BMC performance manager. We are not really satisfied with this tool. We also have set up few cron jobs to monitor few things like ASM disk usage , tablespace usage , mount point usage and all. I would like to know which tool most of the people use in industry. We do no have grid control and I suppose this is the widely used tool. Does someone use any performance monitoring tool ? Or is it managed by SQL queries run by cron ? We have OEM dbconsole configured but we are looking for a tool that can monitor alert log , wait events , regular monitoring stuffs and send an email when something crosses a threshold. Any free tool ? Any tool that can execute SQL query at a pre defined interval and send a mail when query returns output. Please provide your recommendations.
