DESCRIPTION
You can use the smb component to configure a custom monitor, or you can
use the default SMB monitor that the Local Traffic Manager provides.
This type of monitor verifies the availability of an SMB/CIFS server.
You can use this type of monitor to either check the availability of
the server as a whole, the availability of a specific service on the
server, or the availability of a specific file used by a service.
EXAMPLES
create smb my_smb defaults-from smb
Creates a monitor named my_smb that inherits properties from the
default SMB monitor.
list smb
Displays the properties of all of the SMB 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.
debug
Specifies whether the monitor sends error messages and additional
information to a log file created and labeled specifically for
this monitor. You can use the log information to help diagnose and
troubleshoot unsuccessful health checks. The default value is no.
The options are:
no Specifies that the system does not redirect error messages
and additional information related to this monitor.
yes Specifies that the system redirects error messages and
additional information to the
/var/log/monitors/--.log file.
defaults-from
Specifies the name of the monitor from which you want your custom
monitor to inherit settings. The default value is smb.
description
User defined description.
destination
Specifies the IP address and service port 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 and
port supplied by a pool member.
*:port
Specifies to perform a health check on the server with the IP
address supplied by the pool member and the port you specify.
IP address:port
Specifies to mark a pool member up or down based on the
response of the server at the IP address and port you
specify.
get Specifies a file associated with a service. The default value is
none.
The monitor uses the relative path to the service itself when
attempting to locate the file. You are not required to specify a
value for this option; however, if you elect to use this option
you must also specify a value for the service option.
glob Displays the items that match the glob expression. See help glob
for a description of glob expression syntax.
interval
Specifies, in seconds, the frequency at which the system issues
the monitor check when either the resource is down or the status
of the resource is unknown. The default value is 10 seconds.
Important: F5 Networks recommends that when you configure this
option and the up-interval option, whichever value is greater be a
multiple of the lesser value to allow for an even distribution of
monitor checks among all monitors.
manual-resume
Specifies whether the system automatically changes the status of a
resource to up at the next successful monitor check. The default
value of the manual-resume option is disabled.
Note that if you set the manual-resume option to enabled, you must
manually mark the resource as up before the system can use it for
load balancing connections.
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.
password
Specifies the password if the monitored target requires
authentication. The default value is none.
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.
server
Specifies the NetBIOS name of the SMB/CIFS server for which this
monitor checks for availability. You must specify a server for
this monitor to function. The default value is none.
service
Specifies a specific service on the SMB/CIFS for which you want to
verify availability. The default value is none.
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 31 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.
up-interval
Specifies, in seconds, the frequency at which the system issues
the monitor check when the resource is up. The default value is 0
(zero), which specifies that the system uses the value of the
interval option whether the resource is up or down.
Important: F5 Networks recommends that when you configure this
option and the interval option, whichever value is greater be a
multiple of the lesser value to allow for an even distribution of
monitor checks among all monitors.
username
Specifies the user name if the monitored target requires
authentication. The default value is none.
