Network Monitoring with Nagios by Taylor Dondich

By Taylor Dondich

Overview

Network tracking could be a complicated activity to enforce and continue on your IT infrastructure. Nagios, an open-source host, carrier and community tracking application might help streamline your community tracking initiatives and decrease the price of operation.

With this shortcut consultant, we'll pass over how Nagios suits within the total community tracking puzzle. We'll additionally disguise set up and uncomplicated utilization. ultimately, we'll allow you to expand Nagios with different instruments to increase performance.

About the Author

Sensor Networks and Configuration: Fundamentals, Standards, Platforms, and Applications

Advances in networking effect many types of tracking and keep an eye on platforms within the so much dramatic manner. Sensor community and configuration falls below the class of recent networking structures. instant Sensor community (WSN) has emerged and caters to the necessity for real-world functions. technique and layout of WSN represents a extensive study subject with purposes in lots of sectors akin to undefined, domestic, computing, agriculture, setting, and so forth, according to the adoption of primary rules and the cutting-edge expertise.

Example text

For example, if the check_ping command is being run in a service definition for the filesrv1 host, then the $HOSTADDRESS$ macro would be filled in with the network address of that host. The –w parameter specifies what the warning threshold should be when checking for ping responses. Thresholds for the check_ping plug-in follows the format ,%, where is the round-trip average travel time (milliseconds) and is the percentage of packet loss. Whenever these thresholds are met, the service that uses this command will be put into a Warning status.

It implements the use of profiles, which are sets of configuration for hosts and services. Host profiles can also include the initial list of services to include. The use of profiles, along with Monarch’s easy user interface, makes configuration a snap. Furthermore, because it is commercially supported, it is constantly maintained. The navigation on the left gives you the ability to quickly find the items to modify and add quickly. Also included is a quick host search that will immediately pull up a list of hosts as you type.

Fruity is also a Groundwork open source project is and also a configuration tool. Fruity uses Nagios templates extensively but also extends their capabilities. For example, while Nagios cannot specify what services to include in a host template, Fruity provides that functionality. Network Monitoring with Nagios 56 The Fruity Template Editor Fruity has a very strong user community behind it. Users are constantly adding new functionality in the form of patches, which you can download from Fruity’s project page at Sourceforge.
