Hi Michael,
First check whether the reporting database is in sync. Run the following MySQL query:
1. Open a bash shell (bash -login)
2. Navigate to $SPECROOT/mysql/bin directory
cd mysql/bin
3. Launch the MySQL command prompt
./mysql -uroot -proot ddmdb (for Windows)
./mysql --defaults-file=../my-spectrum.cnf -uroot -proot ddmdb (for Linux or Solaris)
4. Run the following MySQL query:
SELECT * FROM landscape\G
If the reporting db is in sync, run the following MySQL query to list the models that are member of a Global Collection:
SELECT entity.entity_name, entity.create_time, entity.destroy_time, model.network_address FROM entity, entitygroup, entitygroupentity, model WHERE entity.entity_ID=entitygroupentity.entity_ID AND entitygroupentity.entity_group_ID=entitygroup.entity_group_ID AND entity.current_model_key=model.model_key AND entitygroup.entity_group_name='<Global_Collection_name>';
Where <Global_Collection_name> is the problematic Global Collection's name
Also check whether there are bucket files in the $SPECROOT/msyql/data/reporting/ directory.
Also check the Tomcat's log file ($SPECROOT/tomcat/logs/sdtout.log or catalina.out).
Thanks,
Silvio
