111 The figure is divided into a number of regions. There are titles on the top that show important statistical information about the configuration and from this execution of
112 \fBamdump\fR. In the figure, the X axis is time, with 0 being the moment
114 was started. The Y axis is divided into 5 regions:
117 How many backups have not been started, how many are waiting on space in the holding disk and how many have been transferred successfully to tape.
120 Percentage of allowed network bandwidth in use.
123 The higher line depicts space allocated on the holding disk to backups in progress and completed backups waiting to be written to tape. The lower line depicts the fraction of the holding disk containing completed backups waiting to be written to tape including the file currently being written to tape. The scale is percentage of the holding disk.
129 Percentage of active dumpers.
131 The idle period at the left of the graph is time
133 is asking the machines how much data they are going to dump. This process can take a while if hosts are down or it takes them a long time to generate estimates.
