    Sending Notifications from PRTG to Twitter

    During the recent outage of the main data center of hoster Rackspace the company used Twitter to communicate information about the outage to the outside world.

    Also our paessler.com website was affected by the downtime and since we could not even reach the Rackspace’s websites we turned to Twitter for up-to-the-minute information. And so did others, too. See: http://technorati.com/blogging/article/when-rackspace-goes-down-twitter-lights/

    Using PRTG, you can also use Twitter to inform your customers easily and automatically via automatic status messages. Keep the world informed about your network whenever there is news - live!

    Howto: Exporting PRTG's Raw Monitoring Data Into Daily CSV or XML Files

    With PRTG Network Monitor, you can analyze your sensor data in various ways. Exhaustive reports for your whole network can be generated as well as historic data reports for single sensors. Still, there are people who just need the data of a sensor in a convenient format to do their own statistics in external programs or to use Excel to do additional computations based on the monitoring data. That is why we have included a XML and CSV export function in PRTG.

    This function of the web interface is handy to export data every few days. But if you need daily data for one or more sensors an automatic solution is more comfortable. With the new CSVExport command line tool finally there is a way to export data of many PRTG sensors with one single line of script! You can use it as an on-demand tool or combine it with Windows task scheduler. Don't be confused by the name – CSVExport is capable of both XML and CSV data export!

    VoIP Monitoring: Why and How PRTG is Different for QoS and IP SLA Monitoring

    Appreciating the benefits of mobile communication, we all have learned to condone some lack of speech quality when using our mobile phones. The possibility to communicate with everyone everywhere often brings a much greater value than an overwhelming speech quality. But when it comes to Voice-over-IP technology, you can have both: Using one of the latest high density (HD) audio codecs, the connection quality can be astonishing (far better than in usual landline communication) and you can even use it wireless on the go with the according mobile provider and device.

    Howto: Rebooting a Computer via Windows Management Instrumentation (WMI) call

    The main task of PRTG Network Monitor is to optimize your network’s availability and performance by avoiding system downtimes. All systems should always be up and running properly. That’s the theory… Still some services fail, even without a complete crash of the server itself. One of the most common methods of recovery is a reboot of the server to get the failing service back online.

    In certain cases, it is useful to have this done automatically. PRTG initiates a reboot when it discovers a service that fails for more than 15 minutes for example.

    Remote reboots can be performed by command lines tools (e.g. from the Sysinternals toolset) or by using a Windows Management Instrumentation (WMI) call. Today I want to share a script that performs remote reboots without any additional software (neither on the client side nor on the server side) and works with every Windows computer that is capable of WMI.

    PRTG Running On a Netbook Monitors the Complete Paessler LAN - Can Your Monitoring Software Do this?

    Today I would like to talk about my favorite toy of recent weeks. I wanted to find the smallest PC in our company that is still able to monitor our complete production LAN network. So I wandered around the office and the slowest PC that I could find was our netbook, a DELL Inspiron Mini 10. Would this tiny PC be able to monitor a thousand sensors with PRTG?

    New PRTG 7.2.2 Beta version is available, includes performance and memory usage improvements

    With version 7.2.2 we will introduce several performance and memory usage improvements. These changes will affect all installations, regardless of the number of sensors, but will be most notable for installations with thousands of sensors. In order to make these improvements available as early as possible for users of PRTG that currently experience memory or performance issues we are publishing beta versions of V7.2.2.

    The most notable change in the new version is the reduced CPU load for the PRTG core server process. For some of our test systems the cpu load of this process has dropped by 90% (!) compared to V7.2.1. This results in an overall faster system and web interface. And it will allow setting up much larger installations, too.

    What to Do When PING Sensors Show Astronomical or Negative Request Times in PRTG

    We have received reports from customers about PING sensors that show very high (ten thousand milliseconds or more) or even negative request times. The reason for this behavior can be a known issue of Hyper-V that shows up when Windows Server 2003 is virtualized under Microsoft Hyper-V when a multi-core CPU is assigned to it.

    Our latest Knowledge Base article "PING Sensors Show Very High or Negative Request Times in PRTG" explains why you might be experiencing such behavior, and how to resolve this issue.

    Monitoring Cisco ASA Firewalls using Netflow 9 and PRTG 7.2

    Recently Cisco has implemented NetFlow 9 for its popular ASA 5500 security and firewall appliances. But this implementation of NetFlow is quite different from what other Cisco devices provide. It is called "Netflow Security Event Logging" (NSEL) and was originally introduced on the Cisco ASA 5580. Now, with the latest firmware (ASA 8.2.x or later), it is now extended to other Cisco ASA models.

    In fact ASA NetFlow was initially not intended to be used for realtime/live traffic analysis (it was created for monitoring of security events)... But it is still a viable option for bandwidth monitoring. And with PRTG Network Monitor V7.2 this option is fully supported, including bandwidth computation, Top Talkers, Top Connections and Top Protocols!

    New Features in PRTG 7.2: The QoS Sensor - Our take on "VoIP Monitoring"

    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.

    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.

    Making Our Website Faster: A Comparison of Cloud Content Delivery Networks (CDNs) with Cloud Storage, Cloud Hosting and Old-Fashioned Hosting

    We 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).

However, there are times when the normal relay means do not suffice, particularly if the main leased line used to connect to the network is interrupted. For these purposes, PRTG Network Monitor includes the option to trigger executable notifications which, combined with the proper external software, can overcome this issue with ease. One software we have been recommending a while is PageGate from NotePage, Inc.

    Don't Use Windows Vista And Windows 2008 for Network Monitoring via WMI!

    Many monitoring features of our PRTG 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.

    New Features in PRTG 7.1 (Part 7): "Official Support for PRTG Virtualizing"

    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.

    How PRTG computes CPU Index, Traffic Index and Response Time Index for your network

    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.

    New Features in PRTG 7.1 (Part 6): "SNMP Trap Notifications"

    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.

    New Features in PRTG 7.1 (Part 3): "Copying Devices by Cloning or Using Device Templates"

    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.

    Installing a Trusted SSL Certificate for PRTG Network Monitor

    PRTG Network Monitor comes with a default SSL certificate so you can securely use the web interface through HTTPS out-of-the-box. But because it is not an official certificate that matches the domain name or IP address of your PRTG installation a web browser will always show an alert ("the certificate is not correct") when it connects to this server (although the transmission is already secure).

    If you want this dialog to disappear you must create, order, and install a trusted certificate. Our latest knowledge base article explains how you can do this by getting a certificate from Comodo InstantSSL. Apart from official paid-for certificates they also offer free 90-day-certificates that work well for PRTG 7.

    New Features in PRTG 7.1 (Part 2): "Toplists"

    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.

    Yesterday's announcement of the public beta of Apple's Safari 4 browser gave us reason to re-evaluate the currently available browsers from a "PRTG Network Monitor"-perspective.

    PRTG uses a lot of AJAX and Javascript functions for its innovative web interface. This fact makes the choice of browser a crucial one for a swift user experience. Back in September we already performed such a shoot-out with the browsers available at that time. Now Safari 4 Beta, Firefox 3.1 Beta and Chrome 2 Beta have entered the arena.

    Monitoring the Available Bandwidth (Part 2)

    Back in August I have already posted an article 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.

    SNMP Tester Debug Tool Updated

    Today we have uploaded a new version of SNMP Tester, our simple but efficient testing tool for SNMP connections. With SNMP Tester you can run simple SNMP requests against a device in your network.

    The program is based on the SNMP technologies that are also built into PRTG Network Monitor and the idea is to have a tool that enables the user to debug SNMP activities in order to find communication and/or data problems in SNMP monitoring configurations. If the SNMP connection works with this test program it will also work with PRTG.

    Creating Artificial NetFlow Data Streams for Testing Purposes Made Simple

    Our latest freeware tool Netflow Generator creates artificial NetFlow Version 5 data streams without the need for NetFlow compatible hardware. It is the perfect tool to test the NetFlow functionality of PRTG or other NetFlow compatible programs.

    NetFlow Generator runs on a PC and sends NetFlow 5 Packets (via UDP) to a specific target computer which processes the data. You can create various patterns and loads of traffic. While the simulator is active it will create NetFlow packets which contain information about the selected traffic pattern. These packets contain the same information as a router/switch would send if it saw the simulated traffic pattern (the simulated traffic itself is not generated).

    How We Created a Globally Distributed Monitoring System with PRTG for Less Than US$220/Month

    As a testbed and demonstration website for the "Remote Probe" feature of our monitoring software PRTG 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.

    The whitepaper illuminates the importance of network management to many areas of IT operational risk management. Certainly its role in managing potential network problems such as switch failures and overloads is a major reason for investing in network management software.
    However, it also can have a role in identifying other potential problems including the download of inappropriate material on business networks and prioritizing various classes of network traffic for optimal business performance. In a world in which even sub-second delays in transactional traffic can cost, these can be crucial elements to address.
