I don't think I'm making my point clearly enough. I know that that RRDtool, and the Terabyte of storage on my desk, permit me to keep records at high resolution for extended periods. However, short of painstakingly examining the high-resolution graphs minute-by-minute I do not see how Smokeping will alert me to transient short duration events. These may be symptoms of some unknown problem which appeared while I was away on holiday: It's 8am on Monday morning and there's a great big heap of paper in my 'IN' tray. An ugly crowd of disgruntled computer users is gathering at the door to the IT dep't offices, and I'd like to take a quick look at what's been going on in the LAN for the past month before I unlock it - so that I don't appear to be quite so clueless as is in fact the case. Networks can be a bit like combat - long periods of nothing happening punctuated by moments of sheer terror. The 'nothing happening' bits establish reference points but little else, and can be characterized with little storage (or screen) capacity. The punctuations are more interesting, and will require more resources. At the moment these punctuations tend to be masked.

I think I've banged on this drum enough now. :) -- 73, Ged. _______________________________________________ smokeping-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/smokeping-users
