Using JRun probes 87

6 Click Register to create the probe.

7 Close all open dialog boxes.

Icons for the monitor and probe appear under the Monitor Manager in the

ClusterCATS Explorer.

To add a new probe to an existing probe monitor:

1 In the ClusterCATS Explorer, select the cluster_name > Monitor Manager >

monitor_name in the left pane.

2 Select Monitor > Properties.

Timeout (sec) Enter a time to indicate how long ClusterCATS waits before a JRun

server failure is registered.

Do not set this value to less than 60 seconds, because ClusterCATS

may restart the JRun server inadvertently (due to network congestion,

for example), rather than detect an actual failure on the JRun server.

Fre qu en cy

(sec)

Enter a time to indicate how often the probe checks the JRun server.

Probes that restart web applications should be configured to run no

more frequently than the time it takes to stop and restart JRun. This is

highly site-specific, because it depends on system resources available

on servers and the volume of traffic at a site.

For probes that do not restart the web application, the frequency

depends on how long you can reasonably afford to have your web

application offline. A minimum frequency of 15 seconds is

recommended.

Return value Enter 0 to make a probe succeed on a successful probing of the page.

Enter a non-zero number to make a probe succeed on a failure.

The default is 0. Only under rare circumstances would you change this

to a non-zero number.
