Filters

Filters – is a mechanism that allows to define events for future processing by the scripts.

Attention!

Be careful using Filter and Subscribe options. Subscribe defines events that will enter VitMLXP Gateway module, Filter – filters the events that entered for future processing by the script. If Subscribe defines that only Alarms must enter VitMLXP Gateway, and Filter defines that Events must be filtered, then script connected to that Filter won’t work – Events will be dropped before VitMLXP Gateway.

Writing a script

Scripts for VitMLXP Gateway can be provided by VIT Company (depending on selected business pack) or created independently by user.


Scripts are the programs on Python. IronPython is used, it’s an implementation for .net Framework platform. It means that except Python’s standard features, types of .net Framework can be used in scripts – as from standard classes library, as created by user.


The following variables must be created before the scripts runs:

  • _GLOBAL stores vocabulary with the following keys:
  1. home type string – the root directory of the plugin;
  2. class type string – plugin’s name of class;
  3. version type string - plugin’s version;
  4. id type string - plugin’s id;
  5. memo type string – for future usage;
  • _ARGV vocabulary type string\string - for future usage;
  • _me type string – script’s id;
  • _clr type string[] – full path to assembles of .net environment, that must be loaded;
  • _in calls shift() – return the input objects of BagIn class subsequently;
  • _out through calls shift() – receives the output objects of BagOut class;
  • _log through calls:
  1. public void shift (string Body);
  2. public void shift (LogSeverity Severity, string Body);
  3. public void shift (string Facility, LogSeverity Severity, string Body) writing to log file is made.

Information about Severity Levels listed in table Severity Levels.

ID Severity Key Description
0 Emergency emerg (panic) System is unusable
1 Alert alert System requires immediate attention
2 Critical crit Critical system’s state
3 Error err (error) Error messages
4 Warning warning (warn) Warnings about potential problems
5 Notice notice Messages about normal but important events
6 Informational info Information messages
7 Debug debug Debug messages


Script receives object of BagIn class as input through variable named _in. This variable is defined and initialized by environment, so it can be called through the first operator.

Input data are transferred through the BagIn.data field. Input data are the object of one of the classes. Object’s class is defined through the field BagIn.type. Type of this field is BagType, enumeration. Script returns output through the variable named _out. This variable must contain list System.Collections.Generic.List<BagOut> that is objects of BagOut class list.

BagOut.Data field is used for outputs. Its values are similar to values of BagIn.data field, adding string. Field BagOut.Action defines the action that must be performed with the output data. Action field is an enumeration. Object’s type of BagOut.Data field must correspond to value of BagOut.Action field or no action will be performed and error message about error in the script will be added to log-file.
