Data Collectors will not connect. Recycled the environment; shut down PC,DC,DA,DR in that order; restarted DR, DA, DC, PC, but the data collectors will not connect. They initially connect but then disconnect after a few seconds. I recycled the environment twice to check this out but the collectors will not connect up.


CA Performance Management 2.4


They were picking up 200 metrics per device on environmental items (fans, power, etc) for thousands of devices. A decision was made to put 2M device metrics went into retirement …at the same time, unbeknownst to them, an additional 770k QoS classmap items were added overnight. That’s a net change of 3 million items in the database, which vertica could not keep up with. 


Stopped the Data Aggregator and the Data Collectors. Removed ~ 770K Qos Classmap items that were added due to a core upgrade configuration push and a discovery. Restarted the Data Aggregator and then restarted the Data Collectors
