Top Conversations (Table)

The Top Conversations (Table) views show data for the top highest-volume conversations on a particular interface. The maximum number of top conversations shown is ten.

The example graphic shows a Top Conversation (Table) view in the CA Performance Center Console, which is set to show conversation rates. You can configure the view to display rate, utilization, or volume information.

The table contains a row for each conversation with the source and destination - The fully qualified DNS host name (if available) and IP address of the servers that initiated and received the conversation data. The table also contains the following rate, volume, or utilization information:

• Rate:
  • (CA PC/NPC) For each conversation, the average rate of total data (Average Total), data that goes to the destination host (Average To), and data that comes from the source host (Average From).
  • (CA PC) For each conversation, maximum rate of data that comes from the source host (Maximum From) and goes to the destination host (Maximum To).

  The rate is calculated by dividing the data volume by the elapsed transmission time.

• Volume: For each conversation, total amount of data (Total), data that comes from the source host (From), and data that goes to the destination host (To), expressed in a scale that is appropriate for the highest-volume conversation.
• Utilization:
  • (CA PC/NPC) For each conversation, average utilization by data that comes from the source host (Average From), data that goes to the destination host (Average To), and total data (Average Total).
  • (CA PC) For each conversation, maximum percentage of interface capacity that is used by the data that comes from the source host (Maximum From) or that goes to the destination host (Maximum To).

  The utilization percentage is calculated by dividing the data rate by the data speed.

Performance Center views show the data from the time range that is defined for the page.
