Connection monitoring with NetStat Agent

I was asked by email how to monitor only one local port, so decided to answer in blog.

Let assume that we have a HTTP server (Apache) on local port 80 and we want to monitor all HTTP connections. With installed NetStat Agent it is very easy to do.

After running NetStat you will see a lot of connections (click to see the large picture):


So we need to create a filter in “Monitor” tab to hide unwanted connections:

  1. In the context menu (right click) select “Clear” to clear all fields.
  2. Set the name of filter: “hide all”.
  3. Set action as “Hide”.
  4. Check on the box “Enabled”.
  5. Press “Add” button to add a new filter.

The result you may see on the screenshot:

netstat monitor

After adding this filter all connections are invisible. So we need another one to show only wanted connections:

  1. In the context menu (right click) select “Clear” to clear all fields.
  2. Set the name of filter: “show http”.
  3. Set the local port: 80.
  4. Check on “Select” action only.
  5. Press “Add”.

See screenshot:

netstat filter

Now if you select “Connections” tab again, you will see only HTTP connections:

HTTP connections only

With NetStat Agent you may monitor HTTP visitors in real-time mode!

[FAQ] How to clear the TraceRoute history?

Each time when you query the route in the TraceRoute tool, NetStat Agent saves the request to cache. But if you want to clear this cache or remove a record from this cache, then you must open the RegEdit and find the path:

HKEY_CURRENT_USER\Software\Flexbyte\NetStat Agent\Tracer

In this folder, you may find records Recent.0, Recent.1 and so on. You may delete all records or only one.

The same you may do to clear the Ping history, but in Ping folder.

How to find netstat logs?

NetStat Agent keeps all logs in %APPDATA%\NetStat Agent\ for current user account.
Usually, it is C:\Documents and Settings\{user account}\Application Data\NetStat Agent\.

You can also open this folder from NetStat Agent. In the program select Log Manager, select a log file, press the right button to call context menu and select “Open Folder” command in the menu.

History overview

The first version of NetStat Agent was released in Jule, 2004.
In version 1.0 netstat, ipconfig, ping and tracert tools was implemented. The program could show the IP routing table and the ARP cache.

NetStat Agent 1.0

In November, some new features like shortcuts customization and ability to show or hide the main toolbar was added.

Since NetStat Agent 1.2 was released (it was in March, 2005), the program closed established connections, renewed or released DHCP configuration. Also was implemented ARP and IP route tools to edit ARP and IP routing tables.

Version 1.3 was released in August, 2005. The new feature of showing the owning process was added. New actions like terminate the process were implemented.

The next version 1.4 had the improved stability and new features like persistent routes, process information, and version checker. It was in March, 2006.

In May, a lot of bugs were solved and NetStat Agent 1.5 was released.

Since version 1.6 was released in September 2006, the program allows to show a country by the remote IP address for netstat, ping and tracert.

NetStat Agent 1.7 was released in November 2006. The country database was updated and some changes in GUI were added.

Unfortunately, the graphical user interface of NetStat Agent was not perfect. Some information was hard readable. So we decided to rewrite the program. The first beta version was implemented in April, 2008. And the major release was done in June 9, 2008.

Now NetStat Agent 2.0 has more handy and easy-to-use graphical user interface. It has new tools like Whois and HTTP Checker. Connection monitor has a lot of new powerful features. In the previous version only one action per monitor rule was available. Now you can select more than one action. The program allows to monitor ARP cache.
