Nagios is a well-known monitoring framework; it’s also known for its plugins, the software components that are actually providing monitoring capabilities. IPHost allows using Nagios plugins directly; we have detailed instructions on setting up and using Nagios plugins; below is the essence of these instructions. Plugins can be anything executable – native application, a script file (including Unix shell files or Windows PowerShell scripts) and so on.
December 12, 2019 It’s a perfect storm: infrastructure silos, increasing volumes of data, growing hybrid infrastructures, and mounting anomalies can bring down enterprise applications, or at least compromise availability or performance. These forces in combination have already outstripped the human capacity and intuition to solve infrastructure issues – which may occur routinely or unpredictably.
The networking field is changing quickly with the emergence of new technologies. This change, along with the onset of digital transformation and increasing cloud-adoption, highlights how businesses have realized the importance of the third platform, as it interconnects mobile computing, cloud computing, social media, and information analytics. 2019 has been the year of edge computing and the dawn of the SD-WAN.
SNMP (Simple Network Management Protocol) is a popular protocol family, supported by majority of network devices, as well as available for every more or less popular operating system. One of most useful features of modern SNMP servers implementations is user-defined extensions. Simply put, one can instruct SNMP server to hold data returned by any user-defined action (such as output printed by a script or program). That can be used to use SNMP as container protocol, to deliver whatever data you need.
Predictive analytics for networks are helping businesses optimize their network performance, anticipate network capacity related requirements, and eventually forecast future much more efficiently than ever. Gartner has estimated the value of network monitoring software market at roughly $2.1 Billion, this figure is presently increasing at a growth rate of 15.9% annually. The demand for predictive analytics in network monitoring software has grown beyond enterprises and datacentres.
Most of existing IPHost monitor types are passive, meaning they are being polled by IPHost – directly, or via remote network agent. There are two “active” monitors, that perform “Event” type alert, when receiving data from remote host: Syslog monitor and SNMP Generic Trap monitor. Although it’s not possible to transform all possible passive monitors to active, there are several approaches to make monitoring nearly real-time in certain situations.
The issue of network baseline arose quite some time ago. Everything started from the understanding that networks are not static entities, but are a set of elements that change over time. It was also understood that networks are not only made up of physical and tangible elements, such as a router or a switch, but we must also have more abstract elements, such as the traffic pattern over a WAN link, for example.
