Schedule Reports


It is a good idea to schedule reports to be run at non-peak traffic hours since generation of reports is a resource hungry process especially for large interface numbers.

 

A Scheduler is configured to set the parameters for automating the generation of reports. The parameters to be set for creating a Scheduler are:

  • Source - The Interfaces or IP Groups which are the source of traffic.
    • Interfaces - The list of interfaces who's bandwidth utilization must be watched. One report will be generated for each interface selected.
    • IP Groups - The IP groups who's bandwidth utilization must be watched. One report will be generated for each IP Group created.
  • Report Type - The type of report to be generated - Consolidated or Custom ( custom report option not available under "IP Groups")
  • Report Generation Schedule - How and when the report is to be generated (e.g.) daily,weekly,monthly,or only once
    • Generate report on - This value determines the time when report is to the generated
    • Generate report for - This value determines the start and the end time for the report
  • Email Address - This is the address to which the generated reports will be sent 

Netflow Analyzer calculates the bandwidth utilization on the specified interfaces / IP Groups every minute. Based on the schedule opted for, reports are generated at various time intervals.The Schedule Reports feature lets you Create new Schedules and Delete existing ones. The Scheduler List page lists all existing schedules , along with the Schedule details,Status, Report types,and the Last Report Generated time.

 

The various columns displayed in the Scheduler List page are described in the table below:

 

Column Description
Name The name of the Schedule when it was created. Click on the Schedule's name to see more information about the schedule's configuration.
Schedule Details Information on when the schedule will run.
Status By default all schedules are Enabled, which means they are active. Click the alert icon to disable a schedule. When this is done, reports will no longer be generated for that configuration. Click the Disabled alert icon to enable the schedule again.
Report Type Whether it is a consolidated report are user-defined Custom report
Last Report Time This column lists the last time when this schedule was run and a report created.
Generated Reports
Clicking on View Reports it is possible to view all the previous reports that have been generated. The number of reports that are stored is based on the user definition in the Schedule Setting page. (By enabling the item "Enable older reports to be accessed from UI" it is possible to retrieve even older reports.) For Daily Schedule up to 90 reports can be stored. For Weekly Schedule up to 104 reports can be stored. For Monthly Schedule up to 60 reports can be stored.

 

Operations on Schedule Reports

    Field Description
    Scheduler Name Enter a unique name to identify this scheduler.
    Description Enter descriptive information for this scheduler profile to help other operators understand why it was created.
    Select Source By default all managed interfaces sending NetFlow exports are selected. If you want this schedule configuration to apply to certain interfaces only, click the Modify Selection link. In the pop-up window, select the required devices and interfaces and click Update to save your changes.

     

    By default all IP Groups are selected. If you want this schedule configuration to apply to certain IP Groups only, click the Modify Selection link. In the pop-up window, select the required devices and IP Groups and click Update to save your changes.

Scheduling Report Generation

The report generation schedule can be chosen from one of the following:

  • Daily - When you opt for "Daily" you have the option to set the time at which the report should be generated. Also, the report could be generated for the previous day or the last 24 hours. When the "Previous Day" option is opted the report is generated for the time period from 00:00 hours to 23:59 hours of the previous day. You have the option to narrow down this time period by using the time filter - filter. For instance if the maximum flow happens during your working hours from 08:00 hours to 18:00 hours you can set it in the window that pops up.

When you opt for the last 24 hours then the report is generated for the flow in the intervening 24 hours (from the time at which the report is to be generated today).

 

Exclude weekends:
When you choose the Exclude Weekend option with "Previous day", reports will be generated on Tuesday, Wednesday, Thursday, Friday and Saturday. These will be reports pertaining to Monday, Tuesday, Wednesday, Thursday and Friday respectively.

When you choose the Exclude Weekend option with "Last 24 hours", reports will be generated on Monday, Tuesday, Wednesday, Thursday and Friday.

  • Weekly - When you opt for the "Weekly" option, you have the option to specify the day and time at which the report needs to be generated. The report could be generated for the "Previous Week" or for the "Last 7 Days". By additionally opting for the "Exclude Weekend" the report can be made to include only data corresponding to monday through friday.

The previous week option would generate the report for the time period Sunday 00:00 hours till Saturday 23:59 hours. When"Exclude Weekends" is enabled the report will be generated for the time period Monday 00:00 hours till Friday 23:59 hours.

 

The"Last 7 Days" option would generate the report for the last 7 days from the time at which the report is to be generated. Again, the exclude weekend option would generate for the last 7 days with the data for the weekend (saturday,sunday) excluded. For instance if the report is to be generated at Monday 10:00 am, with the rules set as "last 7 days" and "Exclude weekend" enabled, then the report will be generated for the time period last week's Monday 10:00 hours to Friday 23:59 hours and from this week Monday's 00:00 hours till 10:00 hours.

  • Monthly - By opting for the "Monthly" option you can set the date of the month along with the time at which the report needs to be generated every month .The report could be generated for the "Previous Month" or for the "Last 30 days". By selecting "Exclude Weekends" the report can be made to include only data corresponding to monday through friday.

When "Previous Month" option is enabled and the report generation date is set to 5-th of every month at 10:00 hours, then the report will be generated for the whole of last month ( first to the last day of the month). When "Exclude weekend" option is enabled then the generated report will exclude all the intervening weekends (saturday & sunday).

 

When "Last 30 Days" option is enabled and the report generation date is set to 5-th of every month at 10:00 hours, then the report will be generated from last month's 5-th 10:00 hours till this month 5-th's 10:00 hours. When"Exclude Weekend" option is enabled then the generated report will exclude all the intervening weekends(saturday & sunday).

  • Only Once - If you wish to generate report only once at a specified time you can do that by opting for "Only Once". The date and time at which the report should be run can be specified. The date & time can be altered by using the icon - cal. The report could be generated for the Previous Day, Last 24 Hours, Previous Week, Last 7 Days, Previous Month, or Last 30 Days. When "Previous Day" option is enabled then the filter button permits the setting of working hours.
