I have to agree with Peter... there are many tools but I'm not certain any of them are great. My two personal favorites are: * Zabbix: Client based and easy to extend. * OpenNMS: Best I've found if you are an SNMP heavy shop. Too many monitoring solutions focus heavily on SNMP, which is why I've been a fan of Zabbix. If we get a decent MIB that may change. For instance, Zenoss is pretty, but its tilted heavily toward SNMP with extending via a custom scripts being ugly and complex, imho. The traditional tools are generally locked into a pre-ZFS, pre-Virtualized, pre-... mentality. If you have a simple box with a traditional /,/var,swap and decent set of NetSNMP MIBs (which are much better on Linux frankly) your in business... but with all the goodies in Solaris today they just don't measure up. Clearly there is a place for a highly extensible replacement for SunMC which could bridge the gaps between so many of Sun's properties (MySQL, Solaris, LDAP, ILOM/ALOM, xVM, etc) in a unique and powerful way. Right now there are some good management tools and bad management tools, and they are all isolated. benr. _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
