Software to monitor system uptime

[Florian Heigl (new acc)]

Monitoring uptimes was quite fancy some months ago, maybe have a look at
http://www.mreriksson.net/uptimes/uptimec/ and friends.

Actually - I forgot to mention - if you want management to see "live" graphs, have a look at MRTG:

I use it to monitor CPU and Memory of my servers, but you can also do uptime as well...

Here's how I monitor HP-UX with SNMP:

Sun and others - you need to script (as snmp is limited).

The package that used to graph the MeasureWare results used to be called PerfView, now renamed. It was sold separately. To get recent information contact your HP OpenView Sales Rep.
