At one place I was at, you had on every Sun box (of the stuff I can remember, I think there was more): EMC ECC Agent for detecting SAN attached storage If connected to a Clariion array, an agent specific for Clariion (whose name escapes me) Tivoli endpoint (which had hundreds of perl scripts to scan what was installed on the system, not just what pkginfo showed) Symantec ESM for security scans HP Measureware (aka OVPA) -- this would run in the RT scheduling class! HP Openview agent (aka ITO) -- this had several hundred perl scripts that would among other things, run uptime, vmstat (for memory usage), mount, df and several others and weren't always written in the most efficient of manners (i.e. lots of unnecessary fork()/exec()s). _______________________________________________ sysadmin-discuss mailing list sysadmin-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
