  5. What is MSG • A messaging infrastructure, based on ActiveMQ • an Apache open-source project • supports open protocols (openwire, stomp, http) • highly configurable • Well defined message specification • Coming from grid probe specification • Suitable for sending records across the wire • Lighweight clients in python • Simple publisher • REST or Stomp sending • Msg-consume2oracle • Durable subscriptions • Stomp -> Oracle view • Currently deployed and in use. • Contact us for giving it a try!

  6. MSG in WLCG monitoring • Grid: • complex infrastructure • many different services • deployed in different environments • where many things can go wrong • We need to monitor the services in order to: • Know when an action to repair is necessary • Help improve the overall reliability • Provide stakeholders with current and historical status information • A vast amount of monitoring data is produced • Local fabric monitoring( e.g., Nagios, LEMON) • Remote monitoring (e.g., SAM) • Visualized in many different tools (e.g., Gridview, Dashboards) • MSG provides reliable, flexible, communication between all the components.
