PRTG Network Monitor on Hyper-V

PRTG Network Monitor on Hyper-V

Wednesday, October 26th, 2011

Founded in 1997 in Germany by Dirk Paessler, Paessler AG company has developed initially a product designed to simplify monitoring of the load machine, and items in its network. With a simple interface and affordable cost rate, it monitors the activity of the computer and the network on a site by centralizing the data to a main site.

Configuration Test:

Installing the main “core” on a Xen Server in a VM Windows 2008 Server. The elements monitored were different machines and network elements of our business (a dozen stations and several physical and virtual servers).

Installation: After reading the “Installation” of the user’s manual, no worries. Everything is well explained, with step by step screen shots to support (it is necessary to refer to the documentation for requirements). Everything will depend on the number of sensors deployed and the frequency of data feedback. These are stored, this allows to have a history and develop comprehensive reports on the status of your network as well as the weaknesses. It will be possible to know that on a particular server at a certain time each month, whether the processor or memory is overloaded. You can also anticipate the problem of hard disks that saturate. Even it will be possible to install a “remote probe” for the monitor, and your mail server. Those with vir tualization platforms are not forgotten, PRTG can also monitor the host server VMware and Hyper-V. The Core part can be installed on both physical servers as a virtual machine. Once the PRTG server is installed, you can install PRTG Remote Probe on a remote site or on a network behind a firewall. The part incorporates the Core collection tools and analysis of the product, the Remote Probe is responsible only to retrieve data from sensors for transmission to the Core. In short, no part of your company will be unattended.

Configuration: Once connected to the web console mode, the interface is very intuitive. Just launch a “self-discovery” of your network and PRTG is responsible for finding almost everything that exists on your network, workstations, servers, network elements (switches, routers …). For example, for a Cisco or HP switch, each port can be monitored. In short, it detects anything that uses WMI, SNMP, “sniff” packets, Cisco Netflow and other protocols. Although this product is mainly for companies using Windows, it may very well live with the other systems if you configure a protocol compatible with the product. Each Probe, once received its configuration from the Core, is independent. This means that a temporary loss of communication is overcome by storing data in a buffer in memory before you can make to the Core once communication is restored.

PRTG can monitor the activity or failure or slow servers bandwidth and the use of network devices, CPU load, free memory and disk space. One can also discover suspicious activity related to equipment or users.

The measurement of QoS and VoIP settings can be done and the control of service levels (SLA). To do PRTG comes standard with everything you need:

• its own DBMS to store the raw data of monitoring;
• its own web server (HTTP, HTTPS) to manage the user interface
• a mail server to automatically send e-mails;
• a report generator;
• engine to view the data graphically;
• an analysis module for the network discovery phase of the sensors and equipment.

Everything is organized hierarchically. To set up user accounts to access the various machinery and equipment, PRTG uses a system of inheritance of parameters that can change in a group or for a particular item, no need to return the settings for each machine.

USE: The easiest way is to launch the console from a web browser. It is interesting to note that the publisher promotes the use of Google Chrome 3. Chrome seems to be more efficient in the processing of large Javascript and Ajax, up to 10x compared to IE 8, and 3 to 5x more than Firefox 3.5.

For those who prefer the format of application, the console is also available in Windows format program, but does require IE 7 or 8. For iPhone, there is an optional iPRTG app. To facilitate monitoring of all of your sites, you can create a map and integrate into groups the various elements of your infrastructure.

Each element of the map includes indicators in color, green if everything is OK with the number of sensors deployed, yellow and red to signal problems. It’s very visual. Then, from any part of the interface, it is possible to go into detail of each probe deployed.

Then feel free to rename each sensor to make it even more telling. Turning now to the rise in alerts, PRTG includes a large number of options: email, event log, net send, message syslog, SNMP trap, message ICQ, MSN, Yahoo, SMS, HTTP action, launching a program, and an audible alert.

In the end of this article I can only say, this is a simple, relatively complete, well thought out application for those who need to monitor their IT infrastructure proactively.
