• The CEMon configuration file is available at /opt/glite/etc/glite-ce-monitor/cemonitor-config.xml.

The most significant parameters you might need/want to modify are:

• sslkeyfile refers to the copy of the host key file belonging to the user running the service (tomcat4);
• sslcertfile refers to the copy of the host key file belonging to the user running the service (tomcat4);
• sslCAfiles refers to the pathname where the CA cert files are installed
• sslCRLfiles refers to the pathname where the CRL files are installed
• backendLocation refers to the pathname of the CEMon backend. This directory will be created when CEMon starts. Be sure that the user running tomcat has the priviledges to create it.
• authzchain refers to the PDPs (the gridMapFile and/or the vomspdp PDP can be enabled)
  • The value for the gridMapFile parameter in the authzchain section refers to the pathname of the grid-mapfile;
• You shouldn't need to change anything for the actions and queryprocessors (contact the developers if you need more info);
• Enable (by uncommenting)/disable (by commenting) the sensors you are interested to/you are not interested in: consider the sensor targets and in case customize it:
  • For the CE, OSG-CE and GRIDICE sensors you might need to customize the scriptURI attribute
• Add the static (predefined) subscriptions (the subscription targets).

Comprehensive documentation on predefined subsriptions is available in Sect. 2.1 and Sect. 3 of the CEMon guide. At any rate:

• As id specify a arbitrary identifier (please be sure to specify different identifiers for different subscriptions)
• As monitorConsumerURL specify a https://... URL if the CEMon notifications should be authenticated, otherwise specify a http://... URL
• Choose the proper sensor and dialect names
• As query specify an expression.
  If the subscription specifies notifications that the CEMon should send to the WMS when the CE is willing to get new jobs, specify in Query the ClassAd expression specifying when the CE wants to receive new jobs.
• Specify the proper actions when the condition is true and false.

If the subscription specifies notifications that the CEMon should send to the WMS when the CE is willing to get new jobs, specify SendNotification as action for "true" and SendExpiredNotification as action for "false"
