The Daily Report feature collects, analyzes, and reports the most significant issues of the fabric in the last 24 hours (from 00:00 to 24:00). The reports present statistical information such as Summary of Traffic, Congestions and UFM events that occurred during the last 24 hours. These statistics are sent to a pre-defined recipients list on a daily basis. It is also possible to specify a non-24-hour range, by updating the UFM configuration file—see section ‎Other Daily Report Configurations for details.

The following are the formats of the Daily Report:

  • Interactive—opened via the browser. The charts are displayed in SVG format. This format can be accessed from the UFM Web UI and is also sent by email as an attachment (see Daily Report View in the Web UI section below).

  • Static—opened via mail client (Outlook, Gmail, Hotmail, etc). The charts are displayed in PNG format.

Daily Report can be activated/deactivated via the /opt/ufm/conf/gv.cfg file.

Note

Daily Reports mechanism is activated by default.

UFM saves the interactive Daily Reports under the /opt/ufm/files/reports/Daily directory. Each report will be saved under a directory with its respective date. For example, report for Sept. 28th, 2014 will be located under: /opt/ufm/files/reports/Daily/2014-09-28/By default, the maximum number of reports that will be saved is 365 (one per day).

To configure the maximum number of reports to save, do the following:

Procedure_Heading_Icon-version-1-modificationdate-1716899916840-api-v2.PNG

  1. Open the /opt/ufm/conf/gv.cfg file.

2. Find the DailyReport section.

3. Set the max_reports option to the desired value. A count of 0 (zero) means no copies are retained. (default and max is 365).

4. Restart UFM.

All the Daily Report configuration parameters can be found in the "DailyReport" section in gv.cfg configuration file.

The following are additional Daily Report configurations options:

  • top_x option specifies the number of results in the "Top X" charts. Max number can be 20. (Default value is 10). top_x value will be applied to all charts existing in the Daily Report.

  • mail_send_interval option specifies the epoch in minutes after midnight that the report can be emailed. By default, if UFM was down during midnight, and was restarted after 1:00, the report of the previous day will be generated and saved, but will not be emailed. This can be changed by editing the mail_send_interval. (default value is 60 minutes, meaning that the report will be send only between 00:00 to 1:00).

  • log_level option specifies the Daily Report log verbosity. Default value is INFO (optional values: INFO, WARNING and ERROR).

  • attach_fabric_health_report option indicates whether or not to add the fabric health report as attachment to the mail. Default value is true (optional values: true or false).

  • fabric_health_report_timeout specifies the max time in seconds, to wait for fabric health report generation. Default value is 900 seconds (15 minutes).
    In case of large fabrics, fabric health report might take longer than the default 15 minutes. User can enlarge the timeout for fabric health report to complete.

  • max_attached_file_size specifies the maximum file size in Bytes for each email attachment that can be sent. Default value is 2 Megabytes.

    If the size of a certain file has exceeded this value, the file will not be sent as an attachment in the Daily Report mail.

    [DailyReport] # top_x specifies the number of results per each top x chart. # max number can be 20.(default is 10) top_x=10 # max_reports specifies the number of reports to save. # A count of 0 (zero) means no copies are retained.(default and max is 365) max_reports = 365 #time interval in minutes after midnight #when passed mail will not be sent mail_send_interval=60 log_level = INFO daily_report_enabled = true attach_fabric_health_report = true fabric_health_report_timeout = 900 # max attached file size in bytes, default is 2M (2097152 Bytes) max_attached_file_size = 2097152

  • max_attached_file_size specifies the maximum file size in Bytes for each email attachment that can be sent. Default value is 2 Megabytes.

  • The start_hour and end_hour options enable selecting a sub-range of the day, during which, the relevant report data will be collected. Since by default this option is configured to collect data from the last 24 hours, the default start_hour is set to 0 (or 00), and the default end_hour is set to 24.

If these options are configured to different values, the generated report will include data from the specified interval only. The start_hour values range is 00 to 23, and the end_hour values range is 00 to 24. The specified end_hour must be greater than the specified start_hour. If, for example, the start_hour is configured to 08, and the end_hour is configured to 10, the generated report will include data collected between 08:00-10:00 (excluding 10:00).

Sidebar

The Sidebar includes general information regarding the fabric, such as: the site name, number of switches and hosts in the fabric, and the dates on which the report was generated.

Navigation between the charts can be done via the menu charts on the sidebar.
