Email Application Check

The email application check widget for custom dashboards showing status and performance.

(For a short video about this topic, click here.)

An “email application check” monitors the availability and performance of an email application. They behave almost exactly like WebART checks. However, only one email application check may be created

The email application check includes a built-in availability service check (passive) and a default threshold check for the Total Transaction Time statistic (an anomaly check may also be configured). The following additional statistics are also collected and available for monitoring with threshold checks:

  • Total Send Time
  • Total Receive Time
  • Send Handshake Time
  • Receive Handshake Time

Much like a WebART check, the email application check isn’t actually a check itself, but rather, a collection of related checks designed to monitor the performance of a single target email application. It is the second most complex of the check types (after the WebART check) and, in some ways, is actually more similar to a managed device than a type of check—in that it is a self-contained, discreet entity that gets checked for availability and is polled for multiple types of statistical data. Since the email application check is not associated with any specific host, it doesn’t appear in device-based dashboards such as the Tactical Overview. Instead, it gets its own dedicated dashboard.

Although it looks very similar to a WebART check, the email application check is configured and activated very differently. A brief explanation of these differences will be helpful in understanding the application of the email check.

Although visually similar, the underlying principals of the two checks are very different. The implementation of WebART checks assumes that multiple and varied web-based applications are being used and monitored by an organization. Thus, OmniCenter allows you to create as many WebART checks as required to monitor all of your different web-based applications. Conversely, most organizations typically tend to rely on a single email application to service the entire organization. Thus, OmniCenter allows you to create only one email application check—as more than one is virtually never necessary.

Another difference is in their use of synthetic checks. Where WebART checks utilize multiple synthetic checks to simulate a complex path of application use, the email application check rarely uses more than a single synthetic check, which forms a core part of the check’s configuration. This synthetic check is where the application and server data for connecting to the email service is configured.

Since the email application check monitors an email system by sending test emails in one direction, a second synthetic check may occasionally be added to test the service using the reverse path.
