WMSMonitor

is a tool to monitor glite-WMSLB instances status and job flow.

An instance of WMSMonitor can collect information from a cluster of distributed gLiteWMS instances about service status and Job Flow. Collected information is aggregated and presented exploiting two main keys: single WMS instance information and Virtual Organization (VO) information.
These two information aggregation keys lead to two parallel branches of metrics presentation in the GUI:

1. WMS view focusing on WMS cluster status and performance monitoring.
   
2. VOView providing Job flow statistics using the VOs as aggregation criterion

WMSMonitor main features:

• Reports a full set of status metrics for each WMS/LB instance monitored
• Provides graphical visualization of job flow through each gliteWMS
• Permanently stores collected data providing historical series visualization
  
• Provides Virtual Organization Job Flow statistics over time
• Provides per user Job Flow statistics
  
• Provides Computing Resource usage statistics
  
• Provides synthetic status metric for gLiteWMS load balancing applications
• Provides a WMSMonitor DataBase Analyzer utility sending notification to Nagios alarming system
