Polling parameters

Load Balancer has a polling plugin that allows you to configure per-server specific tests. This tests are use to determine the server?s status (recheability, response time, general stats ...) with this, the other layers can determine what are the best server for the specific algorithm used. This module support multiple tests, that is, the different submodules can be stacked, so you can do a battery of tests (this tests can use the results from the previous one, so you can create complex checks for your servers).

To configure this module, you have to put all the configuration directives under the polling tag. This directive has the following parameters:

Option Description
interval This parameter configures the number of seconds between polls. This value can be a float (e.g. 0.3). Note that this is the time between the whole battery of polls.
poll_modules
This tag inside the polling configuration directive configure the different poll modules you can add to the poll interface. This modules will be applied in the same order you insert them inside polling tag. There is no configuration options for this tag.

You can found plugin specific details & configuration directives for the generic & http polling plugin here.
