Network Performance Data Report

The Network Performance Data Report can be used to save collected interface traffic or collected device CPU/Memory data to a report in CSV, formatted, report viewer, chart, or PDF format.

Note: When scheduling a report task for interface data, you may wish to report only on a subset of interfaces, rather than all interfaces. To do so, you must first create a group of interfaces, or report group, from the web before creating the task, as described below:

1. To add interfaces to a report group, the prerequisite is to run the Scheduling Live Network Collection task and start the traffic collection from the Traffic Collection Manager. For more information, see Live Network Collection Overview and Performance Management: Traffic Collection Overview.
2. To set up a report group, login to the IP/MPLSView web interface, for example, http://<server-ip-address>:8091 as the admin or wandl user.
3. Next, select Admin > Manage Report Groups.
4. Click Create a New Report Group to add a new report group. Add a group name, description, and then click Add a New Group.
5. Select the Manage Report Groups link to return to the list of groups.
6. Select the newly added group under the Group Name column to modify it.
7. Click Select Interfaces to Add to add interface(s) to the group.
8. Select the router, followed by the desired interface and then click Add Interfaces at the bottom of the page. To add multiple interfaces for the same router, keep repeating this process. To choose all of the interfaces for the router, select the checkbox in the header column.

From the Task Manager, click New Task and create a Network Data Report task.

In the Report Parameters tab, Report Parameters section, type in a report title after Specify the report title.

Next, select one or more report format(s) under Output the report in the following format(s), using the <Shift> or <Ctrl> keys to select more than one format. If selecting the Data Chart or PDF Chart option, note that an aggregate interval will be required in the Query Parameters section (the Aggregate data every... checkbox). Select the type Data Chart to view the resulting report from the IP/MPLSView Web Interface from Live Network > View Traffic Reports > Traffic Utilization Reports. Otherwise, the reports for other formats can be accessed from the IP/MPLSView Web Interface from Main > Shared Documents. Finally, select an output directory in which to save the report under Save the report in the following directory. Note that the output directory will be fixed at /u/wandl/data/report/aggregate if the Data Chart option is in the selected format(s).

Next, in the Query Parameters section, specify the dates to query, either 1) by selecting the arrow to the right of the From and To dates and changing the calendar and clock values or 2) by selecting to query over the last given number of days/hours. After specifying the date range, optionally set an aggregate interval. This time interval should be at least as large as the collection interval. For example, if you are collecting traffic every 5 minutes, the aggregate interval could be set to1 Hour. Finally, you may limit the report query to only a certain number of the highest or lowest data points for that aggregate interval, or select All to use all data points. The operation to perform on these data points (for example, average, 95th percentile) will be specified per attribute in the Report Attributes tab.

For example, suppose you are collecting 5 minute data over the last 7 days. You can view the data per hour if you aggregate data every 1 hour. For any particular hour, there will be 7 days’ data, each with 12 data points (one for each 5 minute period), or 84 data points total. If you select to limit the report query to the Top 10 data points, then for that hour, it will use the top 10 data points out of all the 84 data points.

Report Attributes

In the following tab, the Report Attributes tab, select which element type to report on, Interface or Device. Note that only one element type can be specified per task.

The Device element type is used to report on CPU Utilization, Used Memory, Total Memory, and Memory Utilization. To schedule the task for Device data, the steps are as follows:

1. After selecting the element type, Device, specify the router profile containing the devices that you want to report on.
2. Next, select routers from the router profile and click Add ->to add them to the Routers to be collected list.
3. In the bottom half of the table, select the attributes to report on by selecting Add Attribute and picking the desired attribute from the drop-down list.
4. Each attribute selected will be listed in a new row in the table. Double-click on the cell underneath Operation to select one of the following operations to apply to the data points indicated in the Report Parameters tab: Average, Max, Min, 99Pct, 95Pct, 90Pct, 80Pct, Count, Sum.
5. Additionally, you can select one field to sort by. Note, however, that the sort function will not be applicable if data aggregation is turned on in the Report Parameters tab.

Figure 2: Device Attributes

The Interface element type can be used to report on Bandwidth, Ingress/Egress Traffic, Ingress/Egress Utilization, and Ingress/Egress Error Count of selected interfaces.

To schedule the task for interface traffic data, select Interface as the element type in the Report Attributes tab, and then select the report group if it is desired to report only on a subset of interfaces rather than all interfaces. Next, click Add Attribute and select an attribute that you want to report on. Repeat this for each attribute that will be included in the report.

After an attribute is added to the list, double-click on the Operation field to choose one of the following operations to perform on the chosen data points: Average, Max, Min, 99Pct, 95Pct, 90Pct, 80Pct, Count, Sum.

Again, you can select one field to sort by. However, the sort function will not be applicable if data aggregation is turned on in the Report Parameters tab.

Finally, in the Report Notification tab, you can optionally e-mail the report to a given e-mail address.

Click Next to specify the scheduling parameters, and then click Finish to schedule the task.

After the task has completed, open the File Manager and navigate to the directory in which the report was saved. For files of format CSV or tab delimited, you can double-click to view the file. For files with extension .rpm, right-click the file and select Open in Report Viewer. For interface reports, the data can also be found in the web interface by selecting Live Network > View Traffic Reports > Traffic Utilization Reports. Select the Report Name and then the time stamp to view the interface utilization values.
