Access the Collectors in a System

Procedure

  1. Access Configuration Hub.
  2. In the NAVIGATION section, under the Configuration Hub plugin for Historian, expand Systems, and then select the system whose collectors you want to access.
    The system appears in the main section.
  3. Right-click the system whose collectors you want to access (or select ), and then select Browse Collectors.
    This displays the list of Historian collectors and Offline configuration collectors. By default, the Historian collector instances added to the system appear, displaying the following information.
    Column Description
    COLLECTOR NAME The name of the collector instance. If you select the link in this column, the details of the collector instance appears.
    STATUS The status of the collector. Contains one of the following values:
    • Started
    • Stopped
    • Running
    • Paused
    • Unknown
    CONFIGURATION The source of the tag configuration for the collector. Contains one of the following values:
    • HISTORIAN: Indicates that tags are configured using Historian Administrator.
    • OFFLINE: Indicates that tags are configured using an offline configuration file.
    MACHINE The name of the machine on which the collector is installed.
    VERSION The version number of the collector.
    REDUNDANCY Indicates whether collector redundancy is enabled, which decreases the likelihood of lost data due to software or hardware failures. For more information, refer to About Collector Redundancy.
    REPORT RATE The average rate at which the collector is sending data. This is a general indicator of load on the collector.
    OVERRUNS The total number of data events not collected. In normal operation and under normal conditions, this value should always be zero. If the value is not zero, which indicates that data is being lost, you must take steps to reduce peak load on the system by increasing the collection interval.
    COMPRESSION The effectiveness of collector compression. If the value is low, you can increase the compression deadbands to pass fewer values and thus increase the effect of compression.
    OUT OF ORDER The total number of out-of-order samples for the collector.
    TAG COUNT The number of tags for which the collector collects data.
    COMMENTS The comments that you have entered for the collector.
    Tip:
    • To access the details of a collector, select the row containing the collector instance. The details appear in the DETAILS section.
    • You can show/hide/reorder columns in the table. For instructions, refer to Common Tasks in Configuration Hub.
