Problem monitoring available disk space with Remote Manager
Posted on 2006-04-27
I'm trying to use Remote Manager to view trends in available disk space on a Netware 6 file server. I read that the negative numbers are a cosmetic problem- just ignore the negative sign. But beyond that I really can't make any sense of the graphs I'm getting. For example, over the past month, available space (observed daily by other means) has varied up and down by several G. Just in the last few days it has gone from 17.6 to 17.1 to 14.5 to 12.7. When I ask for a graph of the past week's activity however, I get a graph of G vs time in 1 hour samples that has a straight line across at -1.470428946E9 G. (Actual disk space at the time the graph was taken was 12.5G.) When I ask for a plot of the last month's activity I get an even more bizarre plot with the same flat line at the same level except for a single day dip far into (unlabeled) positive territory. (I have a jpg of this last plt but don't know how to attach it.)
On the Server Health Monitoring screen of Remote Manager, Available Disk Space shows-17,592,183,918,811MB. I haven' kept a separate record of it but it seems to always have approximately this number- only the last few digits varying- which I suppose makes some kind of sense as our total capacity is around 245G. But the actual numbers are confusing to me.
Can anyone tell me how to interpret these strange graphs and figures.
Thanks for any help.
