NEW Installation for emi-WMS/LB, WMSMonitor 3.0

A completely new version of WMSMonitor is made available, for Pre-View testing.
For the moment being we only deploy sensors in a tarball, and you can use the WMSMonitor server Instance available at INFN-CNAF to visualize your instance data.
Notice that this new version can be installed on emiWMS/LB only on SL5/64 platform.

Here some of the novelties introduced with this new version:

  • New web Interface with separate frames for WMS and LB instances
  • Data collection is now asynchronous, in fact a cron job executes sensors on monitored WMS/LB instances and send data to WMSMonitor server consumer
  • Messaging is now based on Active MQ
  • WMS job workload management rates are now derived exploiting LB api
  • Handling of several LB instances for each WMS
  • both globus and emi-cream JSS case is now handled
  • globus JSS error statistics available

To be part of the preview, please write to wms-support asking for the tarball. Then follow instruction:

  1. Make sure you have your emi WMS / LB instance installed and you have root privileges on it
  2. $> cd /opt
  3. $> tar -xvzf WMSMonitor.tgz (--> untar the tarball we provided you with)
  4. $> cp /opt/WMSMonitor/sensors/bin/WMSMonitor.cron /etc/cron.d/
  5. Edit /etc/cron.d/WMSMonitor.cron uncommenting the WMS or LB line respectively (depending on the service hosted in your instance)
  6. IMPORTANT --> tell us the hostname of instance to be monitored
  7. Wait till first cron job to start and check whether a file like /tmp/WMSLOCKFILE_1312453801.45 exists
  8. go to INFN-CNAF WMSMonitor 3.0 monitor server with a valid user certificate and flash player in your browser and enjoy...
