Host coverage
After you activate Application Security, assign permissions, and enable and configure Dynatrace Runtime Vulnerability Analytics, you can review and improve the coverage of hosts on which vulnerability detection is enabled. This can help you determine where there are coverage gaps and how this can relate to the current number of open third-party and code-level vulnerabilities in your environment.
To view your host coverage posture, go to Security Overview > Host coverage. For details, see Application Security overview: Host coverage.
How host coverage is calculated
Host coverage is calculated based on the last 70 minutes and uses all hosts in your environment that run a supported technology. See below the calculation mechanism for third-party and code-level vulnerabilities.
How to increase host coverage
To increase the host coverage for third-party and code-level vulnerabilities, follow the instructions below.
It can take up to 10 minutes until any change is displayed.
Frequently asked questions
Why isn't the host coverage increasing?
If you have followed the steps above to increase the Application Security host coverage, yet the number of covered hosts stays the same, follow the instructions below.
Why doesn't the number of covered hosts match?
If you define tags for hosts covered by Application Security and you notice that the number of hosts on Hosts or Hosts Classic (latest Dynatrace) filtered by your Application Security tags is different from the number of hosts displayed in Security Overview under Host coverage, follow the instructions below.
