Włodzimierz Funika, Filip Szura Automation of decision making for monitoring systems

Motivation Main issue Automation of Network monitoring Rules Understandable Easy to create External Engine (Jboss Drools) Usage of external monitoring systems Extension of existing solutions (Zabbix) Actions described as: Java code Unix action scripts

System architecture System divided into three components:  Server  Decision component  Local-Monitor  Data collector  GUI  Presentation Network 1, 2 – monitored networks RMI (Remote Method Invocation) – standard communication between system components

System architecture Saude-Net GUI Configuration provided during work by the user Web page generation, communication over RMI Saude-Net Server Configuration stored in XML Rules stored in DRL file Rules engine Saude-Net Local-Monitor Dependent on external monitoring system XML configuration Connection over RMI No actions provided for user during work

System details Saude-Net(System for automation of decision making for monitoring systems) Designed for small and medium size networks Multiple actions for resources under monitoring Fully configurable Rule and actions management is easy for network administrator System choose the best action when event occurred in the monitored network Can manage multiple networks

Data From Monitoring Tools Demo List of available actions Trigger the best action GUI component

System details Preference tuning value (PTV) Preference value (PV) Ns - number of services which are currently modified D - number of instances of any action Iw - sum of instances of a specifed action as the best (+1) and other (-1) PV = oldPV + PTV

System features Classic monitoring systems Network events are reported to network administrator Our solution System automatically react on reported failures Reaction based on actual network snap-shot and knowledge In effect, system is able to perform any action when network event occurred Action described as Unix action script Short Java script located in rule

Implementation Server component Calculating preferences for actions Invoke actions Stores actual view of network and actual knowledge base Validation of rules Local-Monitor component Acquiring data from external monitoring systems (Zabbix) Sending data to Saude-Net server GUI component Create rules Simple validation Data representation Form generation Presentation component Extension of Local-Monitor Simple simulator of network

Implementation Used technologies:  Java – available for most operating systems, the same data representation in different systems  JSF – less code than in JSP  Jboss Drools – easy to use, available for java  XML – required by Spring  Spring Framework – allows for Dependency Injection, provides a connection to database Component architecture System divided into separate components Web-based GUI System management by web pages

Conclusions Achievements Automatic actions on network failures Actions described by rules Easy configuration of rules and actions Distributed architecture Limitations All components must be implemented in Java Configuration may not be changed during system work Rules are created only by administrator, our system is not allowed to create its own rules. Future work System should learn automatically from actions taken by the administrator Extensions of Saude-Net system security Redundancy of Saude-Net server component
