Server virtualization is the latest major technology trend in data centers. It provides many opportunities but is not entirely risk-free. Network monitoring can help plan the virtualization of a data center while also minimizing risks for already virtualized environments.
Dirk Paessler, CEO of Paessler AG and an expert in network monitoring has quite a bit of experience in virtualizing data centers, seeing as Paessler AG works with virtualized environments itselfs. His whitepaper provides a comprehensive overview about the opportunities and risks of virtualization and the role network monitoring plays in this context. A great help for administrators and IT executives.

Paessler offers two applications that form a complete network monitoring suite for small-to-medium businesses and is used by large and very large enterprises to provide more detailed visibility into critical
parts of their networks.
Paessler has re-architected all its tools recently, putting them on the optimal technological base and improving their overall functionality, efficiency and usability.
Its tool suite consists of:
PRTG Network Monitor is an easy-to-use Windows application for monitoring and classifying bandwidth usage and for monitoring network uptime/downtime. It provides live readings and long-term usage trends for network devices. PRTG makes early detection of network and website problems easy and affordable. It helps organizations monitor critical network resources and detect systems failures or performance problems immediately, minimizing downtime and its economic impact. SNMP Helper enables PRTG Network Monitor to collect detailed performance information on Windows servers and workstations. Up to several thousand parameters and performance counters on a PC can be monitored with just a few mouse clicks.
Webserver Stress Tool is a powerful HTTP-client/server test application designed to pinpoint critical performance issues on a Web site or Web server that may obstruct delivery of an optimal user experience. By simulating simultaneous access by hundreds or thousands of simultaneous users, it tests Web server performance under normal and extreme loads to ensure that critical information and service are available at response times that users expect. All of these tools come in various editions, and include a free edition to allow users to try out their main features before making the purchase decision.

Those of you who use Paessler’s PRTG might be interested in this article as it discusses (due to the introduction of Google’s new Chrome web browser) which web browser works the best with PRTG.

The Browser War is Back: Choosing the Best Web Browser for PRTG Network Monitor
Since Google have launched their new browser “Chrome” a few days ago development in the world of Web browsers is becoming quite interesting. The new contender Chrome has already created a lot of buzz and includes a number of innovative features that will raise the innovation pressure for the other players.
We wanted to know which one of the four most used browsers is the best for accessing PRTG Network Monitor’s web interface which offers an ajaxified web interface experience.
Just last week we had added experimental support for the WebKit rendering engine (used by Safari and Chrome) to the latest beta of PRTG 7.0.9. So we could start right away testing Chrome against IE7, Safari 3.1 and Firefox 3.
The results in short:
- Don’t use IE7 with PRTG Network Monitor (or other websites with heavy Ajax/Javacript usage), it is simply the slowest browser by far
- You can’t go wrong using Firefox 3, it has the best overall experience
- Safari seems to provide the fastest Javascript processing
- No other browser manipulates DOM objects in the browser window as fast as Chrome
The plain numbers only tell about a speed difference of factor 4 between the fastest and the slowest browsers. From a subjective perspective (meaning: sitting in front of it and using PRTG’s interface) the difference feels more like factor 10 to 20 between Chrome and IE7.
Conclusion:
Because the support for WebKit (Safari/Chrome) is still experimental in PRTG the best choice right now is Firefox 3.
The future seems to look bright for web based application users as faster browsers are coming up. Chrome has raised the bar for the others. Mozilla has already announced a new and improved Javascript engine for the next version of Firefox. Safari 4 is also expected to include a new Javascript engine.
Note: We did not perform any speed tests with IE8 beta 2 yet, although support for IE8 has also been built into V7.0.9 of PRTG Network monitor as of last week. IE8 is expected to be on-par with Firefox 3, but the others are already going the next step…
Details:
Here are the detailed results of our runtime tests with various Javascript functions of the PRTG Network Monitor 7 web interface:
Test 1: Installing various DOM events on the “group.htm” page:
- Safari 3.1: 130 ms
- Chrome: 170ms
- Firefox 3 (with Firebug): 550ms
- Firefox 3 (without Firebug): 170ms
- IE7: 500ms
Test 2: “Tab switching” on the “group.htm” page (tabbing from from the sensor tree view to the “edit root group” page):
- Safari 3.1: 90 ms
- Chrome: 70ms
- Firefox 3 (without Firebug): 110ms
- IE7: 430ms
Tests were performed on a DELL Precision 390 (Intel Core 2 CPU X6800, 2.93 GHz, 4 GB RAM), all four browsers and the PRTG Core Server ran on the same system.
