Monitoring Third-Party Servers with SNMP
Overview: SNMP monitoring of third-party servers
You can configure BIG-IP® DNS, formerly 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 DNS 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 to
monitor a third-party server running SNMP.
- On the Main tab, click.The Monitor List screen opens.
- ClickCreate.The New Monitor screen opens.
- Type a name for the monitor.Monitor names are limited to 63 characters.
- From theTypelist, selectSNMP.
- ClickFinished.
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
DNS, define a third-party host server that is the ultimate
destination of DNS queries.
- On the Main tab, click.The Server List screen opens.
- ClickCreate.The New Server screen opens.
- In theNamefield, type a name for the server.Server names are limited to 63 characters.
- From theProductlist, select a third-party host server or selectGeneric Host.The server type determines the metrics that the system can collect from the server.
- In the Address List area, add the IP addresses of the server.
- Type an external (public) IP address in theAddressfield, and then clickAdd.
- If you use NAT, type an internal (private) IP address in theTranslationfield, and then clickAdd.
You can add more than one IP address, depending on how the server interacts with the rest of your network. - From theData Centerlist, select the data center where the server resides.
- From theProber Preferencelist, select the preferred type of prober(s).Inherit From Data CenterBy default, a server inherits the prober preference selection assigned to the data center in which the server resides.Inside Data CenterA server selects the probers from inside the data center where the server resides.Outside Data CenterA server selects the probers from outside the data center where the server resides.Specific Prober PoolSelect one of the Prober pools from the drop-down list. When assigning the Prober pool at the server level.Note:Prober pools are not used by the bigip monitor.
- From theProber Fallbacklist, select the type of prober(s) to be used if insufficient numbers of the preferred type are available.Inherit From Data CenterBy default, a server inherits the prober fallback selection assigned to the data center in which the server resides.Any AvailableFor selecting any available prober.Inside Data CenterA server selects probers from inside the data center where the server resides.Outside Data CenterA server selects probers from outside the data center where the server resides.NoneNo fallback probers are selected. Prober fallback is disabled.Specific Prober PoolSelect one of the Probers from the drop-down list. When you want to assign a Prober pool at the server level.
- From theStatelist, selectEnabled.
- In the Health Monitors area, assign an SNMP monitor to the server by moving it from theAvailablelist to theSelectedlist.
- From theAvailability Requirementslist, select one of the following and enter any required values.All Health MonitorsBy default, specifies that all of the selected health monitors must be successful before the server is considered up (available).At LeastThe minimum number of selected health monitors that must be successful before the server is considered up.RequireThe minimum number of successful probes required from the total number of probers requested.
- From theVirtual Server Discoverylist, selectDisabled.
- In the Virtual Server List area, create a virtual server to represent (in a pool) the host server that you are creating.
- In theNamefield, type a name for the virtual server.
- In theAddressfield, type the IP address of the host server.
- From theService Portlist, selectSNMP.
- ClickAdd.
- ClickFinished.The Server List screen opens displaying the new server in the list.
Implementation result
BIG-IP®
DNS can now use the SNMP monitor to verify the availability of and
to collect statistics about the generic host.
