A value can be fetched, and before it gets stored it can be dissected or converted in several ways. Preprocessing is managed by a preprocessing manager process, which was added in Javascript preprocessing is done by invoking JavaScript function with a single parameter 'value' and user provided function body. Except where otherwise noted, 1 Item key format. multiply the network traffic value by "8" to convert bytes into bits; 2. Zabbix 2 Item value preprocessing Overview. These The final result of testing preprocessing steps is displayed in all cases when all steps are tested together (when you click on the Test all steps button). In the "Preprocessing" tab of the dependent item select the "Matches regular expression" validation option and fill pattern, for example: ". In this lecture, I add a pre-processing step to the item that instructs the agent to read the windows failed logon You can set up an HTTP agent item to do the api call and gather the full JSON. This section presents examples of using preprocessing steps to accomplish some practical tasks. 1 Usage examples. These examples use regular expressions in the preprocessing steps. Zabbix Join our translation project and help translate Zabbix documentation into your native language. The following illustrations depict the supported syntax. As an example let’s show how the Fahrenheit to Celsius conversion can be configured with JavaScript preprocessing step.
