DESCRIPTION
You can use the snmp-dca component to configure a custom monitor, or you can use the default SNMP DCA monitor
that the Local Traffic Manager provides. This type of monitor checks the performance of a server running an
SNMP agent such as UC Davis, for the purpose of load balancing traffic to that server.
EXAMPLES
create snmp-dca my_snmp-dca defaults-from snmp_dca
Creates a monitor named my_snmp-dca that inherits properties from the default SNMP DCA monitor.
list snmp-dca
Displays the properties of all of the SNMP DCA monitors.
OPTIONS
agent-type
Specifies the type of agent. The default value is ucd.
app-service
Specifies the name of the application service to which the monitor belongs. The default value is none.
Note: If the strict-updates option is enabled on the application service that owns the object, you cannot
modify or delete the monitor. Only the application service can modify or delete the monitor.
community
Specifies the community name that the BIG-IP system must use to authenticate with the host server through
SNMP. The default value is public.
cpu-coefficient
Specifies the coefficient that the system uses to calculate the weight of the CPU threshold in the
dynamic ratio load balancing algorithm. The default value is 1.5.
cpu-threshold
Specifies the maximum acceptable CPU usage on the target server. The default value is 80 percent.
defaults-from
Specifies the name of the monitor from which you want your custom monitor to inherit settings. The
default value is snmp_dca.
description
User defined description.
disk-coefficient
Specifies the coefficient that the system uses to calculate the weight of the disk threshold in the
dynamic ratio load balancing algorithm. The default value is 2.0.
disk-threshold
Specifies the maximum acceptable disk usage on the target server. The default value is 90 percent.
glob Displays the items that match the glob expression. See help glob for a description of glob expression
syntax.
interval
Specifies the frequency at which the system issues the monitor check. The default value is 10 seconds.
memory-coefficient
Specifies the coefficient that the system uses to calculate the weight of the memory threshold in the
dynamic ratio load balancing algorithm. The default value is 1.0.
memory-threshold
Specifies the maximum acceptable memory usage on the target server. The default value is 70 percent.
name Specifies a unique name for the component. This option is required for the commands create, delete, and
modify.
partition
Displays the administrative partition within which the component resides.
regex
Displays the items that match the regular expression. The regular expression must be preceded by an at
sign (@[regular expression]) to indicate that the identifier is a regular expression. See help regex for
a description of regular expression syntax.
time-until-up
Specifies the amount of time, in seconds, after the first successful response before a node is marked up.
A value of 0 (zero) causes a node to be marked up immediately after a valid response is received from the
node. The default value is 0 (zero).
timeout
Specifies the number of seconds the target has in which to respond to the monitor request. The default
value is 30 seconds.
If the target responds within the set time period, it is considered up. If the target does not respond
within the set time period, it is considered down. Also, if the target responds with a RESET packet, the
system immediately flags the target as down without waiting for the timeout interval to expire.
user-defined
Specifies attributes for a monitor that you define. The default value is none.
version
Specifies the version of SNMP that the host server uses. The default value is none.
