DESCRIPTION
You can use the snmp-link component to configure a custom monitor, or you can use the default SNMP Link monitor that the
Global Traffic Manager provides. This type of monitor checks the current CPU, memory, and disk usage of a pool, pool
member, or virtual server that is running an SNMP data collection agent, and then dynamically load balances traffic
accordingly.
EXAMPLES
create snmp-link my_snmp-link defaults-from snmp_link
Creates a monitor named my_snmp-link that inherits properties from the default SNMP Link monitor.
list snmp-link
Displays the properties of all of the SNMP Link monitors.
OPTIONS
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(r) system must use to authenticate with the host server through SNMP. The
default value is public.
defaults-from
Specifies the name of the monitor from which you want your custom monitor to inherit settings. The default value is
snmp_link.
description
User defined description.
destination
Specifies the IP address of the resource that is the destination of this monitor. The default value is *.
Possible values are:
* Specifies to perform a health check on the IP address of the node.
IP address
Specifies to perform a health check on the IP address that you specify, route the check through the IP address of
the associated node, and mark the IP address of the associated node up or down accordingly.
glob Displays the items that match the glob expression. See help glob for a description of glob expression syntax.
ignore-down-response
Specifies whether the monitor ignores a down response from the system it is monitoring. The default value is disabled.
interval
Specifies the frequency at which the system issues the monitor check. The default value is 10 seconds.
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.
port Specifies the port number to which this monitor sends SNMP traps. The default value is 161.
probe-attempts
Specifies the number of times the BIG-IP system attempts to probe the host server, after which the BIG-IP system
considers the host server down or unavailable. The default value is 3.
probe-interval
Specifies the frequency at which the BIG-IP system probes the host server. The default value is 0.
probe-timeout
Specifies the number of seconds after which the BIG-IP system times out the probe request to the BIG-IP system. The
default value is 5 seconds.
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.
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.
version
Specifies the SNMP version the monitor uses. The default value is none.
