If a job does not start as you expect it to, use these tips to see if you can identify the
problem.
Is the start date of the scan later than the current date?
A background scan is not scheduled until midnight on the first day of a background
●
scanning cycle.
If, during a closed window, you schedule an ad hoc scan to run during open
●
windows, the scan does not start until the beginning of the next scanning window.
Have you included at least one IP address in your discovery policy?
Does the group you want to run an assessment scan on have assets in it? If you schedule
discovery and assessment policies to run concurrently and you have more than one agent
assigned to the scanning perspective, your assessment scans may start before the
discovery scans have finished. In that case, your groups may contain fewer assets than
you anticipate, or none at all. To avoid this problem, in the Scan Control policy configure
your assessment scan to start after the discovery scan has ended.
Have you enabled background scanning in a Scan Control policy without defining a scan
window in a Scan Window policy?
Have you verified that your agent is authenticated with SiteProtector? The status in the
Agent view in the SiteProtector Console may be Active, but the agent may not have
authenticated with SiteProtector. To check the authentication status, see "Viewing Status
in the SiteProtector Console" on page 234.
If you are using a custom perspective and a scan does not start as expected, make sure that
you have configured the perspective as required:
In the...
Network Locations policy
ESM policy
Scan Control policy
Table 57: Perspectives in policies
No error is reported for this condition in the Remote Scan window.
Important:
Make sure that you have...
defined a perspective as a network location. (See page 112.)
assigned an agent to that perspective. (See page 110.)
identified that perspective as the perspective from which you
want the groups of assets to be scanned. (See page 87.)
