Adjust the hang detection policy

You can adjust the thread monitor settings by using the wsadmin scripting interface. These changes take effect immediately, but do not persist to the server configuration, and are lost when the server is restarted. The following script provides an example of how to adjust the properties for the thread monitor of a running server using the wsadmin tool:

# Read in the interval, threshold, false alarm from the command line
set interval [lindex $argv 0]
set threshold [lindex $argv 1]
set adjustment [lindex $argv 2]

# Get the object name of the server you want to change the values on
set server [$AdminControl completeObjectName "type=Server,*"]

# Read in the interval and print to the console
set i [$AdminControl getAttribute $server threadMonitorInterval]

# Read in the threshold and print to the console
set t [$AdminControl getAttribute $server threadMonitorThreshold]

# Read in the false alarm adjustment threshold and print to the console
set a [$AdminControl getAttribute $server threadMonitorAdjustmentThreshold]

# Set the new values using the command line parameters
$AdminControl setAttribute $server threadMonitorInterval  ${interval}

$AdminControl setAttribute $server threadMonitorThreshold ${threshold}

$AdminControl setAttribute $server threadMonitorAdjustmentThreshold ${threshold}
