WMSMonitor is composed by a main page reporting an overview of main status variables for all WMS instances monitored
and a page with detailed data for each specific instance.

User Requirements

  • You need the certificate and flash installed on your browser
  • Basic Knowledge of WMSLB architecture

Tool Architecture Overview

  • WMSMonitor SERVER: WMSMonitor runs on a dedicated server machine with a Mysql database to store data, Php, Apache and Python on it.
  • WMSLB INSTANCES: A cron on the WMSMonitor server collects data from each WMS/LB instance executing on it a python compiled function on them. This python executable on each WMSLB instance implements sensors and send data to the WMSMonitor server using snmp.
  • WEB PUBLISHING: Exploiting php based functions, data are retrieved from a local Mysql DB, aggregated and published on a graphical user interface through a secure https protocol. Charts are implemented exploiting "Open Flash Chart", an open source flash based set of libraries.
  • CUMULATIVE STATS: plot reporting on all wms in use by a specific VO

Working On

  • Packaging for current release deployment
  • Implementation of estimates of job latency
  • Old lcg-rb monitoring (probably will not be done because of the decommissioning of lcg-rb )
  • Mail notifications system implementation
