Overview of Monitoring Checks

At the core of Netreo’s operation is a series of monitoring checks that are performed against the devices and applications on the networks it monitors.

Service Checks

A service check queries a service or application on its host device for a response. The response code determines the status of the check. The most versatile check type, with the broadest range of options. (Host availability is monitored using a service check.) Failure of a service check triggers host checking to aid in root cause analysis of the failure.

The status of service checks may be viewed using the Tactical Overview dashboard widget.

See Service Checks for a more complete explanation of service checks.

Host Availability Check

A host availability check is actually just a service check that queries a managed device for its availability on the network. This service check and how it works is fully explained in the Service Check article.

Threshold Checks

Netreo automatically collects and stores a wide range of statistical data from your devices for monitoring and reporting purposes. Using a threshold check, the values of these statistics can be actively monitored as they are collected for the following behaviors.

• Static Thresholds
  Monitors an individual instance of a statistic for unacceptably high and/or low values by comparing the collected values to static threshold values.
• Dynamic Thresholds (Anomaly)
  Monitors an individual instance of a statistic for unusual changes in its regular behavior by comparing the collected values to eight previous values from the same relative timestamp.

The status of threshold checks may be viewed using the Tactical Overview dashboard widget.

See Threshold Checks for a more complete explanation of threshold checks.

Web Application Response Time (WebART) Checks

WebART checks monitor availability and response-time performance of web-based applications. They can step through an application following a typical user path, checking the response time of each step along the way. Applications also may be queried using various reflectors around the globe to measure response performance from a specific region.

The status of WebART checks may be viewed using the Web Application dashboard widget.

See WebART Checks for a more complete explanation of WebART checks.

Email Application Response Time (EmailART) Check

The email check monitors availability and response-time performance of your organization's email application. It also doubles as an Internet connectivity check to confirm your network's ability to communicate with the outside world.

The status of the email application check may be viewed using the Email dashboard widget.

See EmailART Check for a more complete explanation of the EmailART check.

Configuration Check

The configuration check is a global check performed nightly on all eligible managed devices by the config manager. It monitors hosts for changes to their internal device configuration.

The status of device configurations may be viewed using the Config Manager dashboard widget.

See Config Manager for a more complete explanation of the config manager check.
