NAME

 create-http-health-checker - creates a health-checker for a specified load balancer configuration

SYNOPSIS

 create-http-health-checker user admin_user [passwordfile filename] [host host_name] [port port_number] [secure|s] [terse=false] [echo=false] [interactive=true] [help] [url "/"] [interval 30] [timeout 10] config config_name target

DESCRIPTION

This command creates a health checker for a specified load balancer configuration. It only works with the native load balancer provided with the Sun Java System Application Server. It does not work with other load balancers.

OPTIONS

u user

The authorized domain application server administrative username.

w password

The password option is deprecated. Use passwordfile instead.

passwordfile

This option replaces the password option. Using the password option on the command line or through the environment is deprecated. The passwordfile option specifies the name of a file containing the password entries in a specified format. The entry for the password must have the AS_ADMIN_ prefix followed by the password name in capital letters. For example, to specify the domain application server password, use an entry with the following format: AS_ADMIN_PASSWORD=password, where password is the actual administrator password. Other passwords that can be specified include AS_ADMIN_MAPPEDPASSWORD, AS_ADMIN_USERPASSWORD, AS_ADMIN_SAVEDMASTERPASSWORD, AS_ADMIN_MQPASSWORD, AS_ADMIN_ALIASPASSWORD, and so on.

H host

The machine name where the domain application server is running. The default value is localhost.

p port

The port number of the domain application server listening for administration requests. The default port number for Enterprise Edition is 4849.

s secure

If set to true, uses SSL/TLS to communicate with the domain application server.

t terse

Indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-formatted data for consumption by a script. Default is false.

e echo

Setting to true will echo the command line statement on the standard output. Default is false.

I interactive

If set to true (default), only the required password options are prompted.

h help

Displays the help text for the command.

url

The URL to ping to determine whether the instance is healthy.

interval

The interval in seconds the health checker waits between checks of an unhealthy instance to see whether it has become healthy. The default value is 30 seconds. A value of 0 disables the health checker.

timeout

The interval in seconds the health checker waits to receive a response from an instance. If the health checker has not received a response in this interval, the instance is considered unhealthy.

config

The load balancer configuration for which you create the health-checker.

OPERANDS

target

Specifies the target to which the health checker applies.

Valid values are:

• cluster_name, which specifies the health checker will monitor all instances in the cluster.

• instance_name, which specifies that the health checker will monitor this standalone instance.
