Collecting History

RTR can collect data samples for a given probe. These samples are referred to as history data. When RTR collects history, it refers to tests. A test is the lifetime of a probe operation.

samples-of-history-kept

• Use to set the maximum number of entries in the history table for each RTR probe.
• This command enables you to control the number of samples saved in the history table.
• If you set the number of samples to 0, no samples are kept.
• Because collecting history increases memory usage, do so only when there is a problem in your network.
• Example

  host1(config-rtr)#samples-of-history-kept 5

• Use the no version to set the default, 16 hops for pathEcho type, 1 hop for echo type.
• See samples-of-history-kept
