Gathering Traceroute Test Results
You can either poll traceRouteResultsOperStatus to find out when the test is complete or request that a trap be sent when the test is complete. For more information about traceResultsOperStatus, see Monitoring a Running Traceroute Test. For more information about Traceroute MIB traps, see the Generating Traps section in Monitoring a Running Traceroute Test.
Statistics are calculated on a per-hop basis and then stored in traceRouteHopsTable. They include the following for each hop:
- traceRouteHopsIpTgtAddressType—Address type of host at this hop
- traceRouteHopsIpTgtAddress—Address of host at this hop
- traceRouteHopsMinRtt—Minimum round-trip time
- traceRouteHopsMaxRtt—Maximum round-trip time
- traceRouteHopsAverageRtt—Average round-trip time
- traceRouteHopsRttSumOfSquares—Sum of squares of round-trip times
- traceRouteHopsSentProbes—Number of attempts to send probes
- traceRouteHopsProbeResponses—Number of responses received
- traceRouteHopsLastGoodProbe—Timestamp of last response
You can also consult traceRouteProbeHistoryTable for more detailed information about each probe. The index used for traceRouteProbeHistoryTable starts at 1, goes to 0xFFFFFFFF, and wraps to 1 again.
For example, assume the following:
- traceRouteCtlMaxRows is 10.
- traceRouteCtlProbesPerHop is 5.
- There are eight hops to the target (the target being number eight).
- Each probe sent results in a response from a host (the number of probes sent is not limited by traceRouteCtlMaxFailures).
In this test, 40 probes are sent. At the end of the test, traceRouteProbeHistoryTable would have a history of probes like those in Table 1.
Table 1: traceRouteProbeHistoryTable
HistoryIndex | HistoryHopIndex | HistoryProbeIndex |

32 | 7 | 2 |
33 | 7 | 3 |
34 | 7 | 4 |
35 | 7 | 5 |
36 | 8 | 1 |
37 | 8 | 2 |
38 | 8 | 3 |
