Registered Data Collectors
The Data Collectors page displays a table listing all the synchronization jobs that each registered data collector
is running for each vCenter Server added to the application. If multiple data collectors are running,
synchronization jobs are equally distributed among them.
The data collector runs two types of synchronization jobs: polling jobs and listening jobs. Polling jobs are jobs
that run periodically at fixed interval of time and poll the vCenter Server database to fetch the changes in the
database. Each time the job run completes, the last synchronization time for the job is updated. Stats
Synchronization and Storage Synchronization are polling jobs.
Listening jobs start once and perform the initial synchronization. These jobs then register a listener with the
vCenter Server and listen continuously for any update. These jobs run continuously and are not periodic. They
are always in the Active state and never set to Done. These jobs update their status and the last synchronization
time only when an update in the vCenter Server database, for which the job is listening, is processed
successfully.
Table 2-1 lists the information displayed on the Data Collectors page.
Table 2-1. Information About Data Collectors Registered in the Application
Information Type Description
Data Collector ID The ID of the data collector defined in vCenter Chargeback Manager.
Data Collector Heart Beat The time stamp when the data collector was last known to be running. The data collector
updates this information with vCenter Chargeback Manager every 30 seconds. If vCenter
Chargeback Manager does not receive any update from the data collector for more than
150 seconds, then vCenter Chargeback Manager considers the data collector to be down
and reassigns the all jobs to another running data collector, if any.
Data Collector Host Name The name of the machine on which the data collector is running.
Registered Indicates if the data collector is enabled or disabled.
Data Collector Name The name of the data collector provided during the installation.
vCenter Server Name The display name of the vCenter Server added to the application.
