Overview: Notifications for system events

You can easily manage the health of your network by configuring the BIG-IQ system to alert you when specific system events occur for your managed devices. You can receive notifications by having the BIG-IQ system send traps to your SNMP manager and you can also configure the BIG-IQ system to send alerts for certain events to a specified individual.

About configuring SMTP for alerts

To have a specific recipient receive an email message when an alert is triggered by a system event, configure BIG-IQ Device to deliver locally-generated email messages using the internet-standard for electronic mail transmission, Simple Mail Transfer Protocol (SMTP). Sending an email alert ensures that administrators are immediately notified when a specific system event occurs so they can quickly troubleshoot potential issues.

Specifying an SMTP server for alerts

Before you can configure SMPT, you must define a DNS server.

BIG-IQ Device uses SMTP email exchange protocol to deliver email messages. If you want BIG-IQ Device to send email alerts to recipients when specific system events occur, you must define an SMTP host.

  1. Log in to the BIG-IQ system with the administrator user name and password.
  2. At the top of the screen, click System.
  3. Click Server.
  4. In the Name field, type a name for this server.
  5. In the SMTP Server Host and SMTP Server Port fields, type the name of the mail server and its port.
  6. In the From address field, type the email address that you want displayed as the reply-to address for the email.
  7. From the Encryption list, select the encryption level required for the SMTP server.
  8. To require that the SMTP server validates users before allowing them to send email:
    1. Select Yes for the Use Auth setting.
    2. Type the user name and password required to validate the user in the Auth Username and Auth Password fields.
You can now specify email recipients and select alerts on which to trigger an email.

Specifying email recipients and alert conditions

You can specify one or more recipients to receive an email that is triggered by an event that occurs on a managed device. By receiving an alert, a user can quickly troubleshoot potential issues.
  1. Log in to the BIG-IQ system with the administrator user name and password.
  2. At the top of the screen, click System.
  3. Click SMTP Config.
  4. Click Settings.
  5. For the Email Recipients setting, in the Name and Email Address fields, type the information for the recipient who should receive an email when the selected alert conditions are triggered. To add additional email recipients, click the plus ( + ) sign.
  6. For the Alert Conditions setting, select the check box next to each event that should trigger an alert email.
  7. If a threshold is associated with the condition, in the adjacent Threshold field, type a value on which you want to trigger an alert email.
  8. Click the Save button.
You can now click Server and click the Test Connection button to verify that an email is sent and received.

About SNMP integration

SNMP is an industry standard protocol for monitoring devices on IP networks. BIG-IQ Device integrates easily with your SNMP manager, allowing you to centrally manage collected data. Once configured, the SNMP agent sends data collected from BIG-IQ Device to your third-party SNMP manager. BIG-IQ Device is compatible with SNMPv1, SNMPv2c, and SNMPv3.

Integrating with SNMP version 1 or 2

To prepare BIG-IQ Device to interface with your SNMP version 1 or 2 manager, you must complete the following procedures.

  • Configure SNMP agent and access
  • Create an SNMP trap destination

Configuring SNMP version 1 or 2 agent and access

You configure the SNMP agent and provide specific access to BIG-IQ Device so that the SNMP manager can collect data.

  1. Log in to the BIG-IQ system with the administrator user name and password.
  2. At the top of the screen, click System.
  3. Click SNMP Config. The screen displays the SNMP Agent Properties settings.
  4. In the Contact Information field, type the name and email address of the person who is responsible for SNMP administration, and in the Machine Location field, type the location of the SNMP manager system. These details are for informational purposes only, and have no impact on how BIG-IQ Device interfaces with your SNMP manager.
  5. To download the F5-specific MIBs, click the Download MIB link.
  6. In the Addresses/Networks fields, type the IP address and networks (and the netmask if applicable) that the SNMP manager is allowed to access.
  7. To add another address, click the plus ( + ) sign.
  8. Click the Save button located at the top of the panel.
  9. Click the Access tab. The SNMP Access settings display.
  10. In the SNMP v1/v2 Access section, from the Type list, select the appropriate protocol for the SNMP manager's IP address.
  11. In the Community field, type the name of the associated community.
  12. In the Source Address field, specify the IP address for the SNMP manager.
  13. In the OID field, type the associated object identifier (OID).
  14. From the Access list, select the type of MIB access you are providing for this SNMP manager.
  15. Click the Save button located at the top of the panel.
You can now create SNMP trap destinations.

Creating an SNMP version 1 or 2 trap destination

You must configure the SNMP agent and provide access before you create an SNMP trap.
You create an SNMP trap destination to specify where to send SNMP messages, and to define the associated access.
  1. Log in to the BIG-IQ system with the administrator user name and password.
  2. At the top of the screen, click System.
  3. Click the Traps tab.
  4. In the SNMP v1/v2 Destinations section, from the Version list, select the appropriate version of SNMP.
  5. In the Community, Destination, and Port fields, type, respectively, the community name, IP address, and port for the trap destination.
  6. To configure additional SNMP trap destination, click the plus ( + ) sign and specify the settings.
  7. Click the Save button located at the top of the panel.

Integrating with SNMP version 3

To prepare BIG-IQ Device to interface with your SNMP version 3 manager, you must complete the following procedures.

  • Configure SNMP agent and access
  • Create an SNMP trap destination

Configuring the SNMP version 3 agent and access

You configure the SNMP agent and provide specific access to BIG-IQ Device so that the SNMP manager can collect data.

  1. Log in to the BIG-IQ system with the administrator user name and password.
  2. At the top of the screen, click System.
  3. Click SNMP Config. The screen displays the SNMP Agent Properties settings.
  4. In the Contact Information field, type the name and email address of the person who is responsible for SNMP administration, and in the Machine Location field, type the location of the SNMP manager system. These details are for informational purposes only, and have no impact on how BIG-IQ Device interfaces with your SNMP manager.
  5. To download the F5-specific MIBs, click the Download MIB link.
  6. In the Addresses/Networks fields, type the IP address and networks (and the netmask if applicable) that the SNMP manager is allowed to access.
