Network Monitoring 101: Devices vs Tasks

Two crucial network monitoring functions - Devices and Tasks - work together to keep close tabs on your network performance. Learn the difference between monitoring Devices and monitoring Tasks and how each is an ongoing system of maintenance that is constantly deployed to prevent individual target failures.

To understand how network monitoring works it helps to think of a corporate hierarchy with the top C-suite executives overseeing lower level employees, like the line employees working in cubicles. When it comes to network monitoring, a Device is like a C-suite executive, which delegates commands down to a Task, or the cubicle employee. Tasks then oversee individual aspects of a network in order to maintain a functioning website.

Let’s take a look at how these two crucial components – Devices and Tasks – work together to perform routine network maintenance operations:

How a Monitoring Device works:

A Device is simply a way of overseeing individual monitoring functions, such as: monitoring frequency, reporting and alerting. Devices are designed to help facilitate how Tasks interact with a network for the purpose of ensuring that monitoring takes place in an orderly fashion. Devices can be set up that contain a single Tasks, or multiple Tasks. There can also be multiple Devices within a network, each with their own set of Tasks to oversee.

How a Monitoring Task works:

A Task, basically monitors individual “targets” to determine whether, or not, the target is working. A target could be a URL, email server, FTP server, or web-based server. Tasks can be arranged as a single monitoring function within a Device, or as a set of several monitoring instances, or Tasks,  occurring in sequence within a Device.

 

Network Monitoring - Uptime Performance

 

How do Devices and Tasks help keep my network running optimally?

These two crucial network monitoring functions – Devices and Tasks – work together to keep close tabs on your network performance. Without them, it is extremely difficult to keep a constant eye on internal problems when they arise. It is an ongoing system of maintenance that is constantly deployed to prevent individual target failures, such as: broken URLs and server errors from becoming bigger problems.
