About external logging devices

You can use external logging devices to collect log files from BIG-IP® devices for viewing from a web interface launched from the F5® BIG-IQ® Centralized Management system. Currently, only the SevOne Performance Log Appliance (SevOne PLA) is supported. As part of supporting external logging devices, the BIG-IQ Centralized Management system pushes (transfers) BIG-IP device management IP- and self IP address information to the external logging device.

You need to add an external logging device to the management system before you can use it. You add, modify, or remove external logging devices from the management system by selecting System Management > BIG-IQ LOGGING > External Logging Devices .

Once you have added the external logging device, you need to set up authentication with the device so that you can then launch the user interface to manage the device. You perform these tasks by selecting Network Security > Monitoring > External Logging Devices .

Add external logging devices

You can add an external logging device to the F5® BIG-IQ® Centralized Management system to collect log files from BIG-IP devices. Currently only the SevOne Performance Log Appliance (SevOne PLA) is supported.
  1. Log in to the BIG-IQ Centralized Management system with your user name and password.
  2. At the top left of the screen, select System Management from the BIG-IQ menu.
  3. In the list on the left, click BIG-IQ LOGGING and then click External Logging Devices.
  4. Click Add.
    The Add External Logging Device screen opens.
  5. Type a name and an optional description for the external logging device.

    1. Specify the IP address of the external logging device in the IP Address field. If the external logging device is also a query server, select the Use as query server check box to the right of the IP Address field. Query servers are members of the SevOne PLA logging device cluster that process user queries.
    2. In the User Name field, specify the user name of the account used to securely access the SevOne PLA device.
    3. In thePassword field, specify the password for the selected account .
    4. Once the connection information is complete, click Test to verify that the connection information can be used to access the SevOne PLA device. If the test is successful, a green check mark and the text Connection Established are shown in the Test Connection row.
  7. Type the query server information for the device.
    1. Add the first query server IP address in the IP Address field.
    2. Add additional query servers by clicking the + to the right of the description and then supplying an IP address for each in the created IP Addressfields.
    3. Remove query servers by clicking the X to the right of the query server to remove.
  8. Optionally, select the Enabled check box in the Status setting to allow scheduling for data pushes from the BIG-IQ Centralized Management system to the SevOne PLA device, and to enable editing for the other fields in this area.
    • To have the data pushed every day,for the Push Frequency setting, select Daily.
    • To push the data once a month, in the Push Frequency setting, select Monthly, and then select the day of the month.
    • To push the data each week, in the Push Frequency setting, select Weekly and then select one or more days of the week.
  9. Specify when to begin, and optionally end, the scheduled data push.
    Select the date and time using the calendar tool, or type the date, hour, and minute to use. By default, No End Date is selected and must be cleared to specify an end time.
  10. Click Push Now in the Last Push Date setting to manually push the data to the external logging device.
  11. Click Add to save your changes.
    After you successfully add your changes, the screen shows the Last Push Date setting. You can use the Push Now button in that row to manually push data to the external logging device.
The external logging device is added to the BIG-IQ Centralized Management system.
You can now configure authentication with the external logging device so that you can manage logs using the SevOne PLA user interface.
