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.
