      • "poller" gathers data and populates the graphs
      • someone offers munin as an alternative
        • not snmp based, its own agent is used
      • pros
        • cacti is fairly easy to configure
      • cons
        • could be CPU intensive with lots of machines (Perl polling seems to be the problem)
    • zenoss
      • complete network monitoring tool
      • AJAX, integrated with Google Maps (if you don't know where the servers are, everyone laughs at this comment)
    • innotop
      • monitoring innodb, complex output
      • developed by Baron Schwartz
    • mytop
      • similar to Linux's top
      • filter connections on database/host being used
      • queries per sec
    • mtstat-mysql
      • plugin for the system monitoring tool mtstat
      • mtstat provides functionality of vmstat and iostat tools to monitor system activity
    • nagios
      • nagios is more of a notification tool, although it can do graphs
      • pain to set up, text config files, but still the most widely used tool, should be better in upcoming versions
      • NagiosQL is a front end tool for nagios administration (somebody from the audience pointed this out, that's completely new to me!)
      • I offer zabbix as an alternative
      • hyperic is another, apparently very easy to set up, with service autodiscovery
    • MySQL Enterprise Monitor (not free)
      • graphs, monitoring, GUI
      • built by MySQL folks themselves
      • agent based
      • well organized
    • webyog, sqlyog, monyog, mon, heartbeat, moodss, fiveruns are added by the audience members
