Simplicity Has Its Advantages
What VisualPulse 3.0 lacks in sexiness, it makes up for in features.
Sometimes simplicity has its advantages. Take VisualPulse 3.0 from
Visualware, which definitely isn’t the sexiest-looking product when running.
In fact, it looked downright clinical in its reporting and really shouldn’t
be seen outside the computer room. But what it lacks in sexiness, it almost
entirely makes up for in features.
Installing VisualPulse 3.0 is straightforward. You need to have the proper
Java Virtual Machine on the computer running VisualPulse. The documentation
on how to verify the Java VM is quite good, going as far as to instruct
you on where to locate the correct or updated VM. Running the supplied
EXE file performs the install without a hitch.
Next, configure VisualPulse to monitor your resources, send e-mail notifications
(all products support this feature) and so on. Invoke VisualPulse from
the program group created for it, and you’re prompted to pick a TCP port
number for the Web-based interface. Default port 80 won’t work if you
have IIS installed, so you’ll have to choose another. To secure monitoring,
you can set a range of IP addresses to allow access to the Web-based interface.
You configure VisualPulse by updating a text file with your own text entries;
the GUI configuration screen updates a text file with the configuration
Testing the configuration invokes the Web-based interface but, because
the address used is 127.0.0.1 (localhost), it fails to display the Web
page. Visualware may want to change VisualPulse’s test and invocation
to use the actual IP address of the computer, which works correctly.
VisualPulse supports monitoring of IP-based networks. For this reason,
it’s most useful to organizations that need to monitor IP address/TCP
port combinations. For each port monitored, you can also configure e-mail
notification for warnings and errors, for which you can set the thresholds.
If a problem occurs, traceroute capabilities help determine where the
|While Visualware’s VisualPulse 3.0 doesn’t boast
the sexiest graphics, it’s a solid monitoring solution for IP-based
networks. (Click image to view larger version.)
The one thing I don’t like about VisualPulse is the apparent inability
to install it as a service. In order to start the product, I had to log
in, manually invoke VisualPulse and then click Start in the Server Console
to get it going. On Unix systems, this may not be a problem, as you can
start the process to run in the background as a daemon; but on Windows,
it should really be a service.
VisualPulse 3.0, from $200 for a single-server install with 10
elements to $1,500 for 250 elements; Visualware, (703) 802-9006, www.visualware.com.
