Overview
In ExOS v7.x firmware on the Exinda appliance, there are three main styles of graphs that are seen under the 'Monitor' menu:
- Pie charts: To show comparisons between various items (applications, hosts, etc) being monitored to determine how the share of traffic is distributed
- Line graphs: To show trends over time for items such as total throughput, numbers of connections, system utilization, etc.
- Stacked line time graphs: Shows 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 two graphs mentioned above.
In ExOS v6 firmware, only Pie charts and line graphs were used. The stacked line time charts were added in v7 of the firmware and can be seen under items such as the Applications, Hosts, and Subnets reporting.
However, when using a scheduled report that can be set up under Monitor > Schedule Reports, whether it is emailed out on a schedule or generated ad hoc, some of those graphs do not show properly or show up as simple pie charts instead of how they look in the web UI. This article provides a resolution for this issue.
Root Cause
In 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.
Resolution
While this process cannot be automated, it is possible to generate PDF copies of new v7 graphs for any time range by following the steps given below:
- Go to the graph under the Monitor menu.
- Click 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.
