|
| Core Functionality |
|

|
| Ability to trace using UDP (Unix-style) and TCP (using HTTP, FTP, DNS or other TCP port) packets in addition to standard ICMP protocol. |
|
|
|
| Ability to adjust graph scaling to account for conditions where one hop reports extremely bad times, or in the case of long-term monitoring projects with really bad data that skews the graph. |
|
|
|
| Configurable limit to specify how much data to keep in memory. Allows unlimited length monitoring sessions. |
|
|
|
| Ability to "ping" only the final destination to lessen traffic generated. |
|
|
|
| Can define and save workspaces for easy loading of groups of targets (and position of the user interface) to make resuming of sessions easier. |

|
|
|
| Support for QoS enabled networks via capability to modify packet header byte. |
|
|
|
| Define named configurations (collections of settings) for easy switching and selecting when tracing to a target. |
|
|
|
| Monitoring |
|
|
|
| Intuitive graphical display shows route, hosts, packet loss percentage and latencies. |
|
|
|
| Shows min/max response times for range. |
|
|
|
| Ability to save collected data so you can continue tracing that session later. |
|
|
|
| Graphs any host over time, including packet loss and latency. |
|
|
|
| Ability to scroll back and forth over time and zoom in on any specific time period to find out where problems occur...or where they didn't occur. |
|
|
|
| Built-in Whois so Internic servers can be queried by name, or ARIN servers by address to see who owns and runs a particular IP address. |
|

| VoIP specific values like Jitter graphed for each hop in route to aid in VoIP troubleshooting. |
|
|
|
| Comments can be tagged onto history graph to record known conditions or notes. |
|
|
|
| Exports any portion of collected data to a text file for analysis by other software packages, i.e. Microsoft Excel, Open Office, etc. |
|
|
|
| Packet loss percentages shown on route graph and lower history graph. |
|
|
|
| Can have remote script trace back to you as well as you tracing to that target so you can see route to target and return route from target. |
