7. Retain or change the values for CPU, memory, and disk use. Also
note that in the snmp_dca template, the default value for the Agent
Type property is UCD. To configure a monitor for a Windows 2000
agent, change this value to WIN2000.
8. Click Next.
This displays the Configure EAV Variables screen.
9. If you are specifying user-defined metrics, configure the EAV
variables by specifying a unique name and a value for each
Name/Value pair.
The three variables (that is, Name/Value pairs) correspond to OID,
coefficient, and threshold. Note that if the value of the OID variable
is an absolute value, verify that the user-defined threshold value is
also an absolute value. If the threshold value is not absolute, BIG-IP
might not factor the value into the load calculation. The default
user-defined threshold value is 90.
10. Click Next.
This displays the Configure Destination Address and Service (Alias)
screen. We recommend that you use the default values shown here.
11. Click Done.
To configure an SNMP monitor using the bigpipe command
When configuring an SNMP monitor using the bigpipe command, you can
use the default CPU, memory, and disk coefficient and threshold values
specified in the templates, or you can change the default values. Optionally,
you can specify coefficient and threshold values for gathering other types of
data. Note that if the monitor you are configuring is for a type of SNMP
agent other than UC Davis, you must specify the agent type as an argument
to the bigpipe command.
The following command-line examples show various ways to configure an
SNMP monitor. Note that although arguments for user-defined metrics are
shown in uppercase, uppercase is not required.
To configure a monitor for a UC Davis SNMP agent, using default CPU,
memory, and disk use values, use the bigpipe monitor command, as in the
following example.
b monitor my_snmp_dca ’{ use snmp_dca }’
To configure a monitor for a UC Davis SNMP agent, using all default CPU,
memory threshold, and disk use values and specifying a non-default
memory coefficient value, use the bigpipe monitor command, as in the
following example.
b monitor my_snmp_dca ’{ use snmp_dca mem_coefficient "1.5" }’
