Is there any information about packet loss in the tracert output ?

First column shows hop number and last column shows IPs, is other columns showing ping times ?

You might be interested in the PathPing tool distributed with Windows since Windows NT.

PathPing is a network utility supplied in Windows NT, Windows 2000, Windows 2003, Windows XP, Windows Vista and Windows 7. It combines the functionality of Ping with that of Traceroute (in Windows: tracert), by providing details of the path between two hosts and Ping-like statistics for each node in the path based on samples taken over a time period, depending on how many nodes are between the start and end host. The advantages of PathPing over ping and traceroute are that each node is pinged as the result of a single command, and that the behavior of nodes is studied over an extended time period, rather than the Ping's default sample of four messages or Traceroute's default single route trace.

What the heck! I've never known about this. + –  sinni800 Mar 8 '11 at 8:32
    
pathping is great for determining where problems actually exist in the network –  Keltari Aug 29 '11 at 5:32

Yes, packet loss is indicated by an asterisk instead of 'ping times'.

The link given is about traceroute, the unix-like version. The output is not exactly the same, as the pings are shown after the address. –  Gnoupi Jan 13 '10 at 21:33
    
the screenshot is taken from 'Windows' tracert, the asterisk remains. :) –  Molly7244 Jan 13 '10 at 21:38

You can find a detailed information about tracert at this link.

Extract from the link answering your question:

Traceroute is a tool that traces the route that packets travel across a network connection between two hosts. The route between your computer and your domain on our servers will vary from time to time as the network routers involved attempt to find the fastest and most reliable route.

The name (if available) and IP address of each gateway (router) is displayed, along with the round trip time (in milliseconds) for each of three trace packets to reach the specified gateway and return. These intervals may vary widely as a function of network load. Lost packets are indicated by an asterisk (*).

WinMTR is well worth a look if you prefer GUIs.
