addlbmonitor

Use this method to creates a monitor that you can bind to load balancing services. The monitor periodically sends probes to those services to test their availability.

Syntax



Parameters

monitorname

Name for the monitor. Must begin with an ASCII alphanumeric or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. CLI Users: If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, "my monitor" or 'my monitor').
This is mandatory parameter.

type

Type of monitor that you want to create.
This is mandatory parameter.

actioN

Action to perform when the response to an inline monitor (a monitor of type HTTP-INLINE) indicates that the service is down. A service monitored by an inline monitor is considered DOWN if the response code is not one of the codes that have been specified for the Response Code parameter. Available settings function as follows: * NONE - Do not take any action. However, the show service method and the show lb monitor method indicate the total number of responses that were checked and the number of consecutive error responses received after the last successful probe. * LOG - Log the event in NSLOG or SYSLOG. * DOWN - Mark the service as being down, and then do not direct any traffic to the service until the configured down time has expired. Persistent connections to the service are terminated as soon as the service is marked as DOWN. Also, log the event in NSLOG or SYSLOG.
Default value = SM_DOWN.

respcode

Response codes for which to mark the service as UP. For any other response code, the action performed depends on the monitor type. HTTP monitors and RADIUS monitors mark the service as DOWN, while HTTP-INLINE monitors perform the action indicated by the Action parameter.

Calculate the least response times for bound services. If this parameter is not enabled, the appliance does not learn the response times of the bound services. Also used for LRTM load balancing.

deviation

Time value added to the learned average response time in dynamic response time monitoring (DRTM). When a deviation is specified, the appliance learns the average response time of bound services and adds the deviation to the average. The final value is then continually adjusted to accommodate response time variations over time. Specified in milliseconds, seconds, or minutes.
Maximum value = 20939.

units

Unit of measurement for the Deviation parameter. Cannot be changed after the monitor is created.
Default value = NSTMUNT_SEC.

interval

Time interval between two successive probes. Must be greater than the value of Response Time-out.
Default value = 5.
Minimum value = 1.
Maximum value = 20940.

monitor interval units
Default value = NSTMUNT_SEC.

resptimeout

Amount of time for which the appliance must wait before it marks a probe as FAILED. Must be less than the value specified for the Interval parameter. Note: For UDP-ECV monitors for which a receive string is not configured, response timeout does not apply. For UDP-ECV monitors with no receive string, probe failure is indicated by an ICMP port unreachable error received from the service.
Default value = 2.
Minimum value = 1.
Maximum value = 20939.

units3

monitor response timeout units
Default value = NSTMUNT_SEC.

resptimeoutthresh

Response time threshold, specified as a percentage of the Response Time-out parameter. If the response to a monitor probe has not arrived when the threshold is reached, the appliance generates an SNMP trap called monRespTimeoutAboveThresh. After the response time returns to a value below the threshold, the appliance generates a monRespTimeoutBelowThresh SNMP trap. For the traps to be generated, the "MONITOR-RTO-THRESHOLD" alarm must also be enabled.
Maximum value = 100.

retries

Maximum number of probes to send to establish the state of a service for which a monitoring probe failed.
Default value = 3.
Minimum value = 1.
Maximum value = 127.

failureretries

Number of retries that must fail, out of the number specified for the Retries parameter, for a service to be marked as DOWN. For example, if the Retries parameter is set to 10 and the Failure Retries parameter is set to 6, out of the ten probes sent, at least six probes must fail if the service is to be marked as DOWN. The default value of 0 means that all the retries must fail if the service is to be marked as DOWN.
Maximum value = 32.

alertretries

Number of consecutive probe failures after which the appliance generates an SNMP trap called monProbeFailed.
Maximum value = 32.

successretries

Number of consecutive successful probes required to transition a service's state from DOWN to UP.

Minimum value = 1.
Maximum value = 32.

downtime

Time duration for which to wait before probing a service that has been marked as DOWN. Expressed in milliseconds, seconds, or minutes.
Default value = 30.
Minimum value = 1.
Maximum value = 20939.

units4

Unit of measurement for the Down Time parameter. Cannot be changed after the monitor is created.
Default value = NSTMUNT_SEC.

destip

IP address of the service to which to send probes. If the parameter is set to 0, the IP address of the server to which the monitor is bound is considered the destination IP address.

destport

TCP or UDP port to which to send the probe. If the parameter is set to 0, the port number of the service to which the monitor is bound is considered the destination port. For a monitor of type USER, however, the destination port is the port number that is included in the HTTP request sent to the dispatcher. Does not apply to monitors of type PING.

state

State of the monitor. The DISABLED setting disables not only the monitor being configured, but all monitors of the same type, until the parameter is set to ENABLED. If the monitor is bound to a service, the state of the monitor is not taken into account when the state of the service is determined.
Default value = ENABLED.

reverse

Mark a service as DOWN, instead of UP, when probe criteria are satisfied, and as UP instead of DOWN when probe criteria are not satisfied.
Default value = NO.

transparent

The monitor is bound to a transparent device such as a firewall or router. The state of a transparent device depends on the responsiveness of the services behind it. If a transparent device is being monitored, a destination IP address must be specified. The probe is sent to the specified IP address by using the MAC address of the transparent device.
Default value = NO.

iptunnel

Send the monitoring probe to the service through an IP tunnel. A destination IP address must be specified.
Default value = NO.

tos

Probe the service by encoding the destination IP address in the IP TOS (6) bits.

The TOS ID of the specified destination IP. Applicable only when the TOS parameter is set.
Minimum value = 1.
Maximum value = 63.

secure

Use a secure SSL connection when monitoring a service. Applicable only to TCP based monitors. The secure option cannot be used with a CITRIX-AG monitor, because a CITRIX-AG monitor uses a secure connection by default.
Default value = NO.

Default value = NO.

domain

Set of IP addresses expected in the monitoring response from the DNS server, if the record type is A or AAAA. Applicable to DNS monitors.

group

Name of a newsgroup available on the NNTP service that is to be monitored. The appliance periodically generates an NNTP query for the name of the newsgroup and evaluates the response. If the newsgroup is found on the server, the service is marked as UP. If the newsgroup does not exist or if the search fails, the service is marked as DOWN. Applicable to NNTP monitors.

filename

Name of a file on the FTP server. The appliance monitors the FTP service by periodically checking the existence of the file on the server. Applicable to FTP-EXTENDED monitors.

If the expression returns TRUE, the probe succeeds. For example, if you want the appliance to evaluate the error message to determine the state of the server, use the rule MYSQL.RES.ROW(10) .TEXT_ELEM(2).EQ("MySQL").
