PRTG Network Monitor (APPIAMSERVER)
News From Paessler
Although bandwidth isn't as strictly limited as it was some time ago, the perception of seemingly unlimited bandwidth can trigger problems in productive environments. Bandwidth has to be shared by a group of users who, especially in companies, have to rely on their remote services to run smoothly. Therefore it's important to identify fluctuations in bandwidth usage early and distinctly. There are several possibilities to monitor bandwidth. PRTG Network Monitor offers a wide variety of options for bandwidth monitoring like, for example, via WMI, SNMP, xFlow (NetFlow and IPFIX, sFlow, jFlow), or Packet Sniffer. Depending on the type of network devices, each technology has its advantages and disadvantages. For an overview of the different bandwidth monitoring approaches, please have a look at the PRTG manual.
If you think back and try to remember the events that have been influencing your company's IT over the last few months, how many of them were security-related? After Heartbleed and POODLE it's on everybody's agenda to keep their SSL certificates up-to-date. As a PRTG Network Monitor user, you can now easily check the SSL connectivity to your devices' ports with the new SSL Security Check sensor.
If you're a long-time Paessler customer, you will have noticed that, over the last couple of years, we have streamlined our product portfolio and focused our energy more and more on our flagship product PRTG Network Monitor. During this development, for example, the functionalities of PRTG Router Traffic Grapher and IPCheck Server Monitor have merged into PRTG Network Monitor. This not only helps us as a company to make the most of our resources, it also strongly benefits our customers as they get all the capabilities they need to monitor the individual components of their specific IT infrastructure, virtual or physical, in just one product?without having to purchase any add-ons. Simply put, PRTG is the complete package.
In some jobs reaction time is vital. For paramedics and emergency doctors receiving early notification and reliable information can be a matter of life and death. Although your life as an IT administrator is hopefully not threatened by receiving delayed information, being informed as soon as some component or service in your network behaves in an unusual way at least can save your free evening or your weekend.?With push notifications, PRTG Network Monitor now offers a feature that can alert you in the blink of an eye.
You don't use a database unless you have to store important information that is relevant for your business. Consequently it's vital for the stored data to be accessible at any time with the best performance possible. That's why it's of the utmost importance for you as a system administrator to know the current status of your databases and to be alerted if the status changes.
PRTG Network Monitor offers various possibilities for Linux monitoring. The easiest way is to use one of our native sensors that run on the Local Probe or the Remote Probe of a Windows system, located in your network, and gather data via SNMP (Simple Network Management Protocol), WBEM (Web-Based Enterprise Management), or SSH (Secure Shell)?like, for example, monitoring the memory usage of your Linux/Unix system using the SSH Meminfo sensor.
It's almost December and yet 2014 doesn't seem to leave any room for peace and quiet?at least not for system administrators. Even in the year's final quarter there seems to be no break from new headlines about security vulnerabilities: 2014 will definitely be one of those years for everyone in IT to remember. Unfortunately, not all memories are good ones. Some might even be downright scary. Do you recall the morning you went to work and received news about the OpenSSL Heartbleed Bug or the POODLE vulnerability only a few weeks ago? We certainly do?and this by far weren't the only security related surprises, the last few months held in store for IT administrators and managers worldwide.
Did you know with PRTG Network Monitor you have a full scale SNMP Trap Receiver at hand? With SNMP (Simple Network Management Protocol) traps you can easily track reports of important incidents and data. SNMP-enabled devices trigger these asynchronous notifications for various reasons, such as system events, outages, critical conditions, and many more. PRTG collects these messages, stores them in a high performance database, and analyzes their content.
When I started as the Android Developer at Paessler nearly two years ago, my sole task was to build a native Android client that wasn?t this. Beyond the requirement that it be ?better than that?, it was mostly left up to me how it looked and functioned, within the parameters that it works like a PRTG user would expect (so, there?ll be no Tinder-like carousel of "swipe left to favorite this sensor/swipe right to delete it" UI in the Android app, as I?m sure you?re delighted to hear).
Remember when we told you we're on our way to Barcelona? We gave our team a camera to ask happy customers for a short testimonial. A Paessler team would not be a Paessler team though if they did not use their camera for filming a tutorial during breaks.
Six years ago the IT landscape was quite different from what we are used to today. Six years ago? That doesn't seem like such a long time! Well, in technology it is. In this regard you could almost compare tech years to dog years. Let's think back to 2008: Apple has just released the first generation of its iPhone, virtualization was being made more approachable with VMware Workstation 6.5, and Windows 7 had not even reached its beta phase. From today's perspective it seems like another world and it's no surprise also PRTG Network Monitor has come a long way, since version 7 has been released in 2008.
After Heartbleed and Shellshock the next security vulnerability is eager to make 2014 one of the years for admins to remember. This one is called POODLE (Padding Oracle on Downloaded Legacy Encryption) and was found in SSL 3.0, an almost 18-year-old encryption technology that is only used in less than 1% of worldwide SSL traffic?but it's nonetheless still used on the server side to support old browsers like, for example, Internet Explorer 6.
Monitoring via Secure Shell (SSH) enables you to gather information not only from many Linux/Unix and Mac OS systems, but also from the host hardware of your virtualization solution. It is essential to keep a close eye on the host servers as they are the backbone of all your virtual machines. A failure or even unusual behavior could lead to unforeseeable damage and require hours of work that could easily have been prevented.
If you have read all previous articles of this blog series, you're already quite an expert on how to utilize the PRTG Mini Probe API for your monitoring needs. After providing you with the proof of concept for monitoring your Linux systems with the Python Mini Probe, we want to show you another area of application?a probe for monitoring Java applications using Java Management Extensions: the JMX Mini Probe.
Last week has been crazy at the Paessler office ? crazy empty. Everyone was on the road, all over the world. We had a team in New York, in London and in our hometown of Nuremberg. We are just dropping in for a second to tell you about these events because tomorrow we are gone again.
Thank you for using the PRTG Network Monitor
You are using the Freeware version of PRTG Network Monitor. This software covers all aspects of network monitoring: uptime monitoring, traffic and bandwidth usage monitoring combined with concise reporting and analysis features - one clear and simple solution for your entire network.
The software runs 24/7 on a Windows-based machine within your network, recording bandwidth and network usage parameters. Recorded data is stored in a database for historic reports. The easy to use web-based user interface allows to configure the devices and sensors that you want to monitor. You can create usage reports and provide colleagues and customers access to graphs and tables.
All common methods for network usage data acquisition are supported: SNMP and WMI, Packet Sniffing, and NetFlow. For performance and availability monitoring PRTG Network Monitor also includes more than 200 sensor types for all common network services (e.g. Ping, HTTP, SMTP, POP3, FTP, etc.), allowing to monitor your network systems for speed and failures. As soon as outages occur the software will alert you by sending emails, SMS, pager messages and other notifications. Request times and downtimes are constantly recorded in the database and you can compile performance downtime and SLA reports at any given time.
