How do I manage web applications and view their information?

Introduction:

From Entuity v22.0 upwards, you can monitor the SSL certificate expiry and performance metrics of specific web applications as of v22.0 P05. This works by querying specific URLs for their response, and collecting data for streams and attributes specific to the new Web Application type.

You can manage your specified web applications via the Web Application Management page, and view data for them from the Summary dashboard and Web Application Summary dashboard.

For information on the web application object type, please see this note below.

Metrics polled:

When enabled, web application polling retrieves data regarding SSL certificate expiry and additional performance metrics for the web applications that you have added every 5 minutes. Certificate Expiry or Performance Polling can be enabled separately or together for each web application configured.

Key Performance Measures:

• Days to SSL Certificate Expiration
• SSL Certificate Expiration Date
• HTTP Response Code
• Cipher Suite
• DNS Lookup Time
• Connect Time
• SSL Handshake Time
• Wait Time
• Data Transfer Time
• Redirect Time
• Time to First Byte
• Total Request Time
• Redirect Count
• Response Size
• Max Response Size Exceeded
• Response Regex
• Regex Matched

Thresholds, incidents and events:

Web apps have one of the following statuses:

• - Valid SSL certificate or HTTP Response Code returned is between 1-399.
• - 'Warning' threshold, indicates there are between 60 and 31 days until expiry of the web app's SSL certificate. These are the default values, and can be edited - please see this article for help on editing this threshold.
• - 'Critical' threshold, indicates there are 30 days or fewer until expiry of the web app's SSL certificate or the HTTP Response Code returned is 400 or higher.
  • These are the default values, and can be edited - please see this article for help on editing this threshold.
• - Certificate Expiry and Performance Polling are disabled.
• - Polling failed.
• - First poll has not yet run.

Incidents and Events:

• SSL Certificate Expiration Critical Incident
  • SSL Certificate Expiration Critical
  • SSL Certificate Expiration Cleared
• SSL Certificate Expiration Warning Incident
  • SSL Certificate Expiration Warning
  • SSL Certificate Expiration Cleared
• Web Application Down Incident
  • Web Application Status Down
  • Web Application Status Down Cleared
• Web Application Regex Matching Failed Incident
  • Web Application Regex Matching Failed
  • Web Application Regex Matching Cleared

Permission requirements:

To access the Web Application Management page, you will require either Administrator rights or the Inventory Administration user permission. Please see this article for help and information on user permissions in Entuity.

If you do not have these requisite user permissions, you will still be able to view the dashboards relating to web application management.

You can specify which Views the web apps are in, by which you can restrict which web apps can be seen based on which users have access to those Views.

Licensing:

Each individual web app consumes one Basic Device license credit. If there are not enough Basic Device license credits available, a web app will consume a Full Device license credit.

If you attempt to add a web app and there are not enough licenses, the addition will fail with an error message indicating that the web application failed to save.

Please see this article for further help and information on licensing in Entuity.

Note regarding the web application object type - web apps do not need to be taken under management by Entuity:

A web application does not need to be taken under management by Entuity as would a device. In Entuity, a web application is not considered a device. Instead, it is added as a Web Application type object via the Web Application Management page.

A web app is also not linked to any device or server. 

How do I manage web applications and view their information?

Web Application Management page:

The Web Application Management page enables you to view, add, edit, and remove web applications for monitoring.

Dashboards and dashlets:

You can view web application and SSL certificate status information via the following dashboards:

• Web Applications dashboard (in the context of a View)
• Summary dashboard (in the context of a web application object)
