Overview: SNMP monitoring of third-party servers

You can configure the BIG-IP Global Traffic Manager (GTM) to acquire information about the health of a third-party server using SNMP. The server must be running an SNMP agent.

Task summary

To configure BIG-IP GTM to acquire information about the health of a third-party server using SNMP, perform the following tasks.

Creating an SNMP monitor

Create an SNMP monitor that BIG-IP Global Traffic Manager can use to monitor a third-party server running SNMP.
  1. On the Main tab, click Global Traffic > Monitors. The Monitor List screen opens.
  2. Click Create. The New Monitor screen opens.
  3. Type a name for the monitor.
    Important: Monitor names are limited to 63 characters.
  4. From the Type list, select one of the following:
    Option Description
    SNMP DCA Use this monitor to specify new values for CPU, memory, and disk metrics.
    SNMP DCA Base Use this monitor to specify values for metrics other than CPU, memory, and disk usage.
  5. Click Finished.

Defining a third-party host server that is running SNMP

Ensure that the third-party host server is running SNMP. During this procedure, you assign a virtual server to the server; therefore, determine the IP address that you want to assign to the virtual server.
On the BIG-IP GTM, define a third-party host server that is the ultimate destination of DNS name resolution requests.
  1. On the Main tab, click Global Traffic > Servers. The Server List screen opens.
  2. Click Create. The New Server screen opens.
  3. In the Name field, type a name for the server.
    Important: Server names are limited to 63 characters.
  4. From the Product list, select a third-party host server or select Generic Host. The server type determines the metrics that the system can collect from the server.
  5. In the Address List area, add the IP addresses of the server.
    1. Type an external (public) IP address in the Address field, and then click Add.
    2. If you use NAT, type an internal (private) IP address in the Translation field, and then click Add.
    You can add more than one IP address, depending on how the server interacts with the rest of your network.
  6. From the Data Center list, select the data center where the server resides.
  7. From the Prober Pool list, select one of the following.
    Option Description
    Inherit from Data Center By default, a server inherits the Prober pool assigned to the data center in which the server resides.
    Prober pool name Select the Prober pool that contains the BIG-IP systems that you want to perform monitor probes of this server.
  8. In the Health Monitors area, assign an SNMP monitor to the server by moving it from the Available list to the Selected list.
  9. From the Virtual Server Discovery list, select Disabled.
  10. In the Virtual Server List area, create a virtual server to represent (in a pool) the host server that you are creating.
    1. In the Name field, type a name for the virtual server.
    2. In the Address field, type the IP address of the host server.
    3. From the Service Port list, select SNMP.
    4. Click Add.
  11. Click Create. The Server List screen opens displaying the new server in the list.

Implementation result

BIG-IP GTM can now use the SNMP monitor to verify the availability of and to collect statistics about the generic host.
