Modifying Global Parameters

Global or System Parameters are divided into two tabs, Probes and Networking. Most clusters will work with default
values on these tabs. To view or modify the default global parameter values:
1. Log into the Administrative Interface using a login that has add/del access for global parameters to add,
remove, and update parameters; write access to update parameters with existing values; read access or greater
to view (see "Logging In" on page 52).
2. Select
Equalizer > Probes
modify the global networking parameters.
3. Change the appropriate fields.
4. Click the commit button.
The following two sections explain the global probe and networking parameters.

Global Probe Parameters

Selecting
Equalizer > Probes
The global probe parameters are described below:
probe interval
probe timeout
strikeout threshold
Equalizer Installation and Administration Guide
to view/modify the global probe parameters, or
displays the global probe parameters:
The target interval between TCP probes of a cluster that has
been marked failing in the load balancing daemon's internal
tables. If the server does not respond to strikeout threshold
(see below) additional TCP probes after it is marked failing, then
the server is marked down. These additional probes are at least
probe interval seconds apart. This value is solely a target; the
monitoring process adjusts itself based on a number of factors,
including system load. The default value is 20 seconds.
The time in seconds that the probe daemon waits for a response
from a server to a TCP or ACV probe. The default is 10 seconds.
The number of additional TCP probes sent to a server that is
marked failing (see probe delay, below), and after which the
server is marked down if no response is received. The default
value is 2; must be between 1 and 6.
