To set the number of history buckets that are kept during the response time reporter probe's lifetime, use the buckets-of-history-kept response time reporter configuration command. Use the no form of this command to return to the default value.
buckets-of-history-kept size
no buckets-of-history-kept
size Number of history buckets kept during the response time reporter probe's lifetime. The default is 50 buckets.
50 buckets

A response time reporter probe can collect history and capture statistics. By default, history is not collected. When a problem arises where history is useful (for example, a large number of timeouts are occurring), you can configure the lives-of-history-kept response time reporter configuration command to collect history. You can optionally adjust the buckets-of-history-kept , filter-for-history, and samples-of-history-kept response time reporter configuration commands.
When the number of buckets reaches the size specified, no further history for this life is stored.
Collecting history increases the RAM usage. Only collect history when you think there is a problem. For general network response time information, use statistics.
If history is collected, each bucket contains one or more history entries from the probe. When the probe type is pathEcho , an entry is created for each hop along the path that the probe takes to reach its destination. The type of entry stored in the history table is controlled by the filter-for-history response time reporter configuration command. The total number of entries stored in the history table is controlled by the combination of samples-of-history-kept, buckets-of-history-kept , and lives-of-history-keptresponse time reporter configuration commands.
Each time the probe starts a response time reporter operation, a new bucket is created until the number of history buckets matches the specified size or the probe's lifetime expires. History buckets do not wrap. The probe's lifetime is defined by the rtr scheduleglobal configuration command. The probe starts a response time reporter operation based on the seconds specified by the frequencyresponse time reporter configuration command.
The following example configures probe 1 to keep 25 history buckets during the probe's lifetime:
rtr 1 type echo protocol ipIcmpEcho 172.16.161.21 buckets-of-history-kept 25 lives-of-history-kept 1
| Command | Description |
|---|---|
| filter-for-history | Defines the type of information kept in the history table for the response time reporter probe. |
| lives-of-history-kept | Sets the number of lives maintained in the history table for the response time reporter probe. |
| rtr | Configures a response time reporter probe. |
| rtr schedule | Configures the time parameters for a response time reporter probe. |
| samples-of-history-kept | Sets the number of entries kept in the history table per bucket for the response time reporter probe. |
