Viewing the near real-time status of the data warehouse components

Overview

The Core Services - Near-real-time Warehouse service page displays near real-time status of the BMC Helix Capacity Optimization data warehouse components.

To access this page:

1. Log in to the BMC Helix Capacity Optimization console.
2. Click Administration > DATA WAREHOUSE > Status.
3. In the Processing section, click Processing details.
   The Core Services - Near-real-time Warehouse service page is displayed. 
   

The page displays the following tables:

• Processing status
  This table provides the following information about the data warehouse queues:

  Column	Description
  Timestamp	The current date and time (updated every 5 minutes).
  Structure	Can be one of the following: APPL (domain), SYS (system), or WKLD (business driver).
  Thread launcher	Name of the thread launcher (*).
  Active threads	Number of threads concurrently running for the last sample.
  Queue length	Number of series still to be processed for the last sample.
  Estimated processing time	Values for this column are derieved using QueueLength/SeriesThroughput. This estimate indicates how long we can expect a request to stay in queue maximum based on how fast is the processing now. It uses HH:MM format to display the estimated processing time. For example, If you have left the datahub off during weekend. When you start you have 10,000 series in the queue (QLen) and Throughput is now 10 series/sec. So you can expect to be done with all requests in 1000 seconds. So a series will have to wait a max of 1000 seconds in the queue before you can see the results. How to use: It would be handy in recovery situations to understand when the entire queue will be done based on throughput. In general it could give good information for cases with low throughput to understand if the DWH is accumulating delay.
  Series throughput [series/s]	Number of series processed per second.
  Processing throughput [rows/s]	Number of processing per second; typically, the number of rows.

• Daily and monthly rollup
  The following table provides information about the time series data that is aggregated daily or monthly.

  Column	Description
  Timestamp	The current date and time.
  Structure	Can be one of the following: APPL (domain), SYS (system), or WKLD (business driver).
  Status	The status of the warehouse job, such as completed or failed.
  Aggregation level	The level of data aggregation, such as daily or monthly.
  Average series throughput	The average throughput of the series that are processed.
  Processed series	The number of series that are processed.
  Processing time	The processing time of the time series data in hours.
  Prev. 7 days throughput (series/s)	The throughput of the processed series over the last 7 days.
