SummaryIn ExOS 7.x firmware, some of the reporting graphs on the web UI look different than corresponding graphs and tables generated by scheduled reports, while others are identical.
OverviewIn ExOS v7.x firmware on the Exinda appliance, there are three main styles of graphs that are seen under the 'Monitor' menu:
- Pie charts and corresponding tables in order to show comparisons between various items (applications, hosts, etc) being monitored to determine how the share of traffic is distributed
- Line graphs showing trends over time for items such as total throughput, numbers of connections, system utilization, etc.
- Stacked line time graphs, which show not only the total accumulation for items, but also show distribution underneath for various items contributing to the total at any given time; a combination of the above two graphs.
CauseIn v7 of the firmware, the appliance began to use different reporting and monitoring processes in the back end in order to be able to generate the new stacked line time charts. The pie charts and typical line graphs still use the old v6 processes for gathering statistics. The scheduled reports, as in v6, still fully utilize the older processes and as a result, they do not have any of the new stacked line graphs located in it, forcing information to be presented in the old style. This means that there is no way to compare things like host usage, subnets, etc. at a specific time.
WorkaroundWhile this process cannot be automated, it is possible to generate PDF copies of new v7 graphs for any time range by simply going to the graph itself under the Monitor menu and clicking the PDF icon in the top right hand side of the page.
This will generate a report for the time range immediately and prompt you to download it. This cannot be automated but it can be done in conjunction with scheduled reports manually in order to get a fuller view of the network performance at the time range specified.
