Real time traffic analysis for IIS?

I am looking for real time traffic analyzer for IIS. A tool which can tell me which web sites are causing the most traffic in terms of number of requests or number of bytes.

There are times when my bandwidth is getting pretty saturated and I need to know what's causing it. I need another tool that's more IIS specific, beside using a network sniffer.

You can use wireshark.  Besides it being free it is easy to figure out.

This is from their website:

Wireshark has a rich feature set which includes the following:

Deep inspection of hundreds of protocols, with more being added all the time
Live capture and offline analysis
Standard three-pane packet browser
Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
The most powerful display filters in the industry
Rich VoIP analysis
Read/write many different capture file formats: tcpdump (libpcap), Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
Capture files compressed with gzip can be decompressed on the fly
Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platfrom)
Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
Coloring rules can be applied to the packet list for quick, intuitive analysis
Output can be exported to XML, PostScript®, CSV, or plain text

Now their website:


Good luck
Use the performance monitor. Let it gather some metrics and see what the average load is. Severing the pages may not tax the hardware so monitor the network performance.

I am looking for something more sophisticated than a log analyzer like WebTrends or Visistat. I have hundreds of web sites on the server, each one logging to a separate file.

ost of the analyzer either analyze the log file which is not real time or add a javascript which is not feasible because I don't own the site.

I need something that bolts to IIS like an ISAPI filter or monitors the network card intelligently.

I am aware of Wireshark which everyone recommends. Does it have the capability for queries?

Perhaps, something like this?  http://webscripts.softpedia.com/script/Web-Traffic-Analysis/IIS-Tracer-31085.html

never used it before, but looks like it might give you what you're looking for.

I have find CommView which can automatically save to a file which can be imported into a database for querying later.

I couldn't get Wireshark to do what I wanted. The exported file can't be imported into a database because each record has labels and more information than what's displayed on the screen,
