Trace Measurements

A series of ICMP Echo requests are sent out by the agent. For each request the time-to-live (TTL) is increased. The destination IP address for the requests is set to the trace destination.

You can specify a number of parameters for traceroutes:

host = <hostname or IP address>, that is the traceroute endpoint.

MaxTTL = Maximum number of routers that will be traced, the default is 30.

Timeout = Number of milliseconds that the agent will wait for a reply, the default is 5000 (5 seconds).

Repetitions = Number of times a traceroute should be repeated to improve precision of measurement, the default is 2.

For each TTL a report line is produced that reflects the response time to the particular router. If a router doesn’t respond to the ICMP Echo request, the line inserted has a router IP of 255.255.255.255, and the status code will be set to 10000.

Parameter	Description
JumpCount	The Time To Live (TTL) value used to reach
Router	Depending on the Status code this value is: 1. 0 - address of the final destination 2. 10000 - 255.255.255.255 ‘ghost’ router address non-replying router 3. 11010 - address of the final destination - destination was never reached 4. 11013 - address of in-route router
Success	Depends on the Status code: 1. 0 - 1 (success) 2. 10000 - 1 (success) 3. 11010 - 0 (failure) 4. 11011 - 0 (failure) 5. 11013 - 1 (success)
Status	The following codes are used: 1. 0 - Proper reply from the final destination 2. 10000 - Non replying in-route router 3. 11010 - Non replying destination 4. 11011 - Bad request - no request sent (ICMP library unavailable, or destination IP couldn’t be resolved) 5. 11013 - Packet expired in transit, this is the code reported by all in-route routers.
Iterations	Always 1
Response time	Number of microseconds that the round-trip has taken. If the operating system reports a round-trip time of zero, a value of 500 microseconds (0.5 milliseconds) is used.
