2010-Oct-17iPRTG for PRTG is available in a brand new version. As a 'Universal App' it now supports iPhone, iPod, and even the iPad with its higher resolution. iPRTG is the iPhone application for network monitoring while on the go. It enables you to quickly connect to your PRTG installation and review all monitoring results as well perform simple actions such as acknowledge alarms, pause and resume monitoring, add favorites, etc. The new version is now available for download at iTunes store. If you have already purchased iPRTG, you can download the update for free.
2010-Aug-10web based applications! They offer three big advantages: 1. web based applications only require a web browser on the end-users’ computers 2. usage is, in most cases, easy to learn 3. they can be centrally managed by the administrators We anticipated this trend in 2006 when we designed the architecture of PRTG 7 which completely relies on a web based user interface.
2010-Jul-13June 30th 2008, we released the last new major version: version 7 of PRTG Network Monitor. Since then PRTG has seen numerous improvements, new features and enhancements. Now, the next major version is getting close to completion. With version 8 PRTG takes another big leap forward with hundreds of improvements and many new features.
Clustering and MoreWith this new version we introduce a unique new feature that allows PRTG users to create fail-safe, distributed monitoring systems: The "PRTG Cluster" where up to 5 PRTG instances ("nodes") work together to create a fail-safe monitoring system. We have implemented numerous new features:
As of now, iPRTG 2 is available in the iTunes store! iPRTG is a personal network monitoring assistant for your PRTG Network Monitor software. Always with you on your iPhone, it allows to view the current status of your network on the go. Using iPRTG, you benefit from many interesting features—wherever you are:
2010-May-27last August users of the popular smartphone Apple iPhone can download and install a dedicated app that brings PRTG to their phone. We have received a lot of feedback and requests for enhancements. During the last months our partner company beyond content went back into their labs and actually rewrote the whole app from scratch! New development tools for the iPhone and some new API calls on behalf of PRTG's API allowed the developers to come up with an app that just blows you away! So today I am happy to announce the new version 2 of iPRTG.

2010-Mar-30just-released version 7.3.3 of PRTG we are introducing significant improvements for PRTG's built-in web server. Especially for large installations with thousands of sensors, the user experience of both Windows and web interface will be noticeably faster. In our lab, we run installations of PRTG with 10,000 and 20,000 sensors. The 20,000 sensor installation, for example, runs on a water-cooled PC (Alienware) with a Core-2-Quad CPU at 2.66 GHz, i.e. quite a powerful machine. But with PRTG 7.3.2 most web pages took 5 - 10 seconds to generate. Some even took 30 - 50 seconds. We thought that's too slow. So we got our hands dirty, found a few things that needed to be changed and – wow! – with PRTG 7.3.3 all pages are being delivered in one second or less.

The latest and improved version of PRTG is now publicly available. Our development team has been working hard since the release of version 7.1 - hundreds of new features, improvements have been implemented and some bugfixes as well. Especially for users with more than a handful of sensors/devices the new version means major usability progress: The brand-new Windows GUI and the new multi-edit features make working with many sensors so much faster and easier.
Google has released the latest version 3 of their web browser Chrome only one year after version 1 and just one week after I have published the results of our latest browser shootout (which already awarded the first place to Chrome 2). So it was time to rerun the tests and include Chrome 3. And the results are impressive.
During the beta test of version 7.2 of PRTG Network Monitor I am posting a few posts about new features that we have built into this new version. In yesterdays blog entry I wrote about the new QoS sensor which measures various service quality parameters of a network connection by probing the connection with UDP packages. Today I would like to introduce our second new monitoring solution for VoIP quality, the new IP SLA sensor.
2009-Aug-27beta test of version 7.2 of PRTG Network Monitor I am posting a few posts about new features that we have built into this new version. Today's post is about our new "QoS Sensor" which is used to monitor the quality of a network connection by looking at "quality of service" parameters like jitter, packet loss, packet delay variation, and other readings. Slight variations of these parameters usually have only little effect on TCP-based services (e.g. HTTP, SMTP, etc.). But for UDP-based services like VoIP and video streaming a steady stream of data packets is crucial. The sound quality of a VoIP call drops dramatically when UDP packets are not received in a timely fashion, if packets are lost or reordered.
During the beta test of version 7.2 of PRTG Network Monitor I will write a few posts about new features that we have built into this new version. If you are using Amazon EC2 (Elastic Comput Cloud) to host one or more servers then this new sensor is for you. Amazon offers the CloudWatch service for EC2 instances since May this year and it provides performance data for individual instances on EC2. Usage of the service costs $0.015 per hour for each Amazon EC2 instance you choose to monitor.
2009-Aug-19Don't let monitoring your network tie you to your desk! With iPRTG your network monitor is where your iPhone is. iPRTG is the iPhone App for network administrators using the PRTG Network Monitor software by Paessler AG to monitor and administrate their network. iPRTG is the one and only clear and simple viewer for the entire network monitoring environment. The iPhone requests the monitoring data directly from the PRTG server and iPRTG displays it in an "iPhonic" way.
Making Our Website Faster: A Comparison of Cloud Content Delivery Networks (CDNs) with Cloud Storage, Cloud Hosting and Old-Fashioned HostingWe are currently preparing a new setup for the hosting of www.paessler.com. Because visitors to our website are coming from all over the world we decided to host CSS, images and media files on a global content delivery network in order to provide a swift website experience for all visitors. The advantage of using a CDN (Content Delivery Network, see wikipedia) is that website visitors will be served media files from the closest "edge-server" of the CDN and not from our own servers in the Rackspace data center in Dallas TX (the dynamic HTML would still be served from Dallas, though).

2009-Jun- 3PRTG Network Monitor software (as well as many other monitoring tools) are based on WMI. Everything is fine with WMI on Windows XP and Windows 2003, even for larger networks. But when Vista and Win2k8 come into the game it is a completely different story altogether. We have received reports from a number of users that ran into trouble when using WMI monitoring for larger networks - and all of them were using Vista or Windows 2008. We tried to find out what aspects affect the performance of WMI monitoring. We selected ten servers and PCs in our testing lab. All of them ran a different version of Windows. We measured the WMI performance between them.

Monitoring Cloud Performance with PRTG: Comparing Disk Speed for Instance Stores and EBS Volumes on Amazon EC2
Here is another insight on Amazon's EC2 services that we found during our recent cloud monitoring experiments: For a couple of days we ran our load test sensor for disk speed monitoring on instance stores (disk volumes which come with each instance) as well as on EBS volumes (Amazon's Elastic Block Store) for all available instance types. The results for a period of 48 hours are shown in this graph from PRTG Network Monitor:
Monitoring Cloud Computing Performance with PRTG: CPU, Disk, Memory Speed Comparison of Amazon EC2 Instance TypesLast Friday I have posted our first results from recent monitoring experiments on Amazon EC2 instance types were we published a comparison of average performance of the Amazon EC2 instance types. Now, three days later, I can amend our observations on how the CPU, disk and memory performance of our EC2 instances behave if you monitor them for a couple of days (in our case between April 1st and April 5th). The following graphs (taken straight out of PRTG Network Monitor) show the results of our CPU, disk and memory tests for the five available instance types. Each dot shows the results of one test:

During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. Virtualization has become a fundamental part of the IT eco-system. Many of our customers have already moved or will soon move considerable parts of their computer systems into virtual servers. Of course we also use virtualized systems heavily in our own software test lab together with a lot of real hardware. With version 7.1 we now officially support running PRTG Network Monitor on virtualized platforms. PRTG already supports native monitoring of VMware servers since last October. Now it is a logical step to support running PRTG virtualized, too.
2009-Mar-26January 30th 2009) PRTG Network Monitor version 7.1 was thoroughly tested by our own team as well as hundreds of beta testers. Internally we called this intense test project the "mother of all software tests" and we are quite satisfied with the results: we are now convinced that the upcoming release of PRTG 7.1 is
- 1. the best software we have ever created and
- 2. the best tested software we have ever released.
In order to provide graphs that show a quick status overview of your complete network (or a part of it) PRTG computes so-called "index" values based on the measurements of all sensors. The "index" graphs are synthetic values between 0% and 100% based on current sensor measurements and their historic maximum values. The calculation of these index values works similar to a stock index which is computed using the current values of selected stocks. For each group and device PRTG shows four values in a graph.
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. In PRTG V7.1 we have added a new option for notifications: If an event occurs (e.g. a sensor's state changes from up to down) PRTG can now send SNMP Traps to a computer where a so-called Trap Receiver is listening. Trap receivers usually store these messages for later analysis and/or forward traps to the administrators using other means of alerting.
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. Another new break-through feature of PRTG 7.1 is the automated probe updating. PRTG users who have set up one or more remote probes in their configuration will love this feature.
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. Another interesting new feature in PRTG 7.1 is "Email Round Trip Monitoring". Two new sensor types ensure the end-to-end delivery of emails and make it possible to monitor availability and performance of a complete email delivery process.
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. After configuring a device with one or more sensors there are two options to copy it:
- Cloning a device: Is the best option to simply duplicate a device only a few times with all its sensors and settings.
- using a device templates: Is the preferred option if you have many similar devices and if you do not want to create all devices manually through the web interface. This is also the better option if the devices do not have the same number of ports.
2009-Mar- 5support for virtual Windows servers in their European EC2 (Elastic Compute Cloud) datacenter. Together with the US-East datacenter (which offers hosting of Windows systems since last fall) Amazon now offers two locations where you can run Windows servers on their cloud hosting systems.
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. Packet Sniffing and NetFlow sensors can not only measure the total bandwidth usage, they can also break down the traffic by IP address, port, protocol, and other parameters. The results are shown in so-called "toplists". This way PRTG is able to tell which IP address, connection or protocol uses the most bandwidth. PRTG looks at all network packets (or streams) and collects the bandwidth information for all IPs, ports and protocols. At the end of the toplist period PRTG stores only the top entries of each in its database.
During the beta test of PRTG Network Monitor 7.1 I will post a number of blog articles about new features in the new version. One of the coolest new features in V7.1 is the "Sensor Factory". It allows to combine measurements from two or more sensors into one new sensor.
2009-Feb-13article which explains how complicated it is to measure the bandwidth that is actually available for you. One of the problems I mentioned was that if you want to exactly measure the available bandwidth you would have to saturate your data line and then measure the achieved bandwidth. But if you saturate your data line you are actually prohibiting all other traffic. Not a good idea for everyday life.
2009-Feb-13Google Code. The prtg7addons project on Google Code will host various add-on tools for PRTG Network Monitor and their source code - created by Paessler and PRTG users.
In order to make the results of your network monitoring available in your Intranet or for customers we recommend using the "Maps" feature of PRTG Network Monitor in conjunction with a map of your network. Visualized results make it much easier for your users to understand the situation of your network. Here are a samples for (rather simple) network maps including live monitoring data (created with PRTG 7):
But how do you create a map of your network? There are paid-for options, e.g. Microsoft Visio, and other programs that you must install locally on your computer. But in many cases using one of the following free online options may serve you well for a quick map!
2008-Nov-11Card Packet Counter is a small tool that shows live stats and a short term statistical history about the network data packets and streams passing a local network card. Using the Packet Sniffing Engine of PRTG Network Monitor it looks at all network packets that pass a specific network card. It was mainly developed to debug technical issues between PCs and the packet sniffing engine which is built into PRTG Network Monitor. But it is also a very useful tool for other network problem finding situations - and it's free.
Cloud computing pioneer Amazon Web Services recently announced support for hosting of Windows based servers on its Amazon Elastic Compute Cloud. This new offering can now easily be used to create a cheap Remote Probe server for your own installation of PRTG Network Monitor! To extended our own global network of probes (we use it as a demo website for visitors interested in PRTG and as a test platform for PRTG as well) we created a new remote probe running on EC2 in less than 30 minutes. Here are the steps we took:
2008-Oct-16PRTG Network Monitor use the software to simply monitor their Internet router and to find out how much bandwidth they consume in a month. The Linksys RVS 4000 is a good and common example and we will look at its details for this blog post. Many other Internet access routers will show quite similar behaviour. If you let PRTG's auto-discovery scan the router's IP you will get the following sensors:
2008-Oct- 9PRTG Network Monitor (and out of technical curiosity) we have set up a network of monitoring stations around the globe based on PRTG. To keep our costs low we have used virtual server offerings from grid hosting or VPS hosting companies for our remote probe installations. Virtual servers are much cheaper than dedicated offerings but provide only limited resources of course. In order to act as a remote probe for PRTG that only sends out a few monitoring requests into the Internet every few seconds a VPS is perfectly enough - in all cases we purchased the smallest Windows VPS offering available and saw decent results. PRTG's remote probes usually require little CPU cycles. We have to keep in mind that - due to bottlenecks caused by other VPSs on the same hosting system that may use a lot of CPU or bandwidth - the measured values will show a lot more jitter than they would on a dedicated system. For a long term perspective these fluctuations do not really matter. And they also do not matter for pure availability monitoring (even if the probe system has little CPU power, it will still find out whether a webserver can be reached or not). As a result we now have a network of 5 monitoring stations around the globe that are connected to one core instance of PRTG Network Monitor.
With version 7.0.9 we are introducing specialized sensors for monitoring of VMware ESX servers. These sensors talk directly to the SOAP interface of ESX servers in order to monitor the system health of the host machine as well as the system health of each individual virtual machine.
2008-Sep- 5"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.
Starting with Version 7.0.8 PRTG Network Monitor (currently in public beta testing) includes a web-based API that enables external programs to have access information from the monitoring database and to manipulate the object database of PRTG. The API is HTTP based and uses a set of URLs to access the data.
With version 7.0.8 (currently in beta) we have added a new user interface that is optimized for the Apple iPhone. This feature enables the user to quickly check the status of his servers and sensors on the road.

Introduction to PRTG 7 Part 6: Why we created the PRTG 7 user interface to be a little.... differentThis another posting of my series of introductory blog posts about our new software "PRTG Network Monitor 7" which is currently undergoing a public beta test. We began the development process of PRTG 7 in 2006. The first step was to make a list of features that we (and our customers) wanted to have in the software additionally to all the functionalities of PRTG 6 and IPCheck 5. We listened to feedback from our users and one major task was to create a new software that was able to monitor 10-50 times as many sensors as the old programs and - as a consequence - we also needed a new user interface to enable the users to handle hundreds and thousands of sensors with ease.
This another posting of my series of introductory blog posts about our new software "PRTG Network Monitor 7" which is currently undergoing a public beta test.The hierarchical list of sensors is not only used to group sensors to organize them, there is also an important aspect involved that we call "Inheritance".
This another posting of my series of introductory blog posts about our new software "PRTG Network Monitor 7" which is currently undergoing a public beta test.In PRTG Network Monitor the actual monitoring is performed by "Sensors". One of these sensors always monitors one single aspect of a network device, e.g.
Here is another posting of my series of introductory blog posts about our new software "PRTG Network Monitor 7" which is currently undergoing a public beta test.The main layout of PRTG Network Monitor's web-based user interface consists of the Global Status Bar at the top, the Header Area with the main menu and quick-search box below it and finally the main page content.
Over the next few weeks I will publish a number of introductory blog posts about our new software "PRTG Network Monitor 7" which is currently undergoing a public beta test.
Let's begin with a short overview of what PRTG 7 is:
2008-Apr-15new version 7 of PRTG brings together the functionalities of PRTG 6 and IPCheck 5 into one concise network monitoring application and adds a number of new features, especially some functions to ease and automate management for larger networks.
