Specify how scans are run

The following settings can be specified for each list of computers in the configuration file.

Note Any time specified in the configuration file must be in Universal Coordinated Time (UTC) 24-hour clock format.
Tip You can test Virtualization Scan Controller's performance in a non-production environment. Edit your Sophos Enterprise Console Anti-Virus and HIPS policy to exclude folders, and use the DefaultWaitHint option (discussed in this section) to reduce the time allowed for a scan. Depending on the results, you can decide on the best settings.

DefaultWaitHint

This setting controls how much time is allowed for a scan to be run on one computer before a scan starts on the next. The value is set in minutes and must be greater than 0, the default is 30 minutes.

This setting applies the first time that scans are run on the computers. After the first run, Virtualization Scan Controller uses information from previous runs to determine how much time is allowed.

Example:

[Group X]
DefaultWaitHint=40
COMPUTER1.domain.name
COMPUTER2.domain.name
COMPUTER3.domain.name

MaxScanTime

This setting defines how long Virtualization Scan Controller will allow for a scan to run successfully. The value is set in minutes and must be greater than 0, the default is 180 minutes. If a scan takes longer, Virtualization Scan Controller assumes that the scan has terminated, and starts a scan on another computer.

Example:

[Group X]
MaxScanTime=120
COMPUTER1.domain.name
COMPUTER2.domain.name
COMPUTER3.domain.name

MinTimeBeforeNext

This setting controls how often a scan can be run on each computer in a list. The value is set in minutes, and controls the minimum time allowed between successive scans on the same computer. The value must be greater than 30, the default is 1440 minutes or 1 day.

The MinTimeBeforeNext setting should be set to a value which is greater than the duration of the longest scan in the list. It should also, therefore, be greater than the MaxScanTime setting for the list.

Example:

[Group X]
MinTimeBeforeNext=90
COMPUTER1.domain.name
COMPUTER2.domain.name
COMPUTER3.domain.name

MaxConcurrentScans

This setting controls the maximum number of computers in a list that can be running a scan at the same time. The value must be 1 or greater, the default is 1.

Example:

[Group X]
MaxConcurrentScans=3
MinTimeBeforeNext=90
ALPHA
BETA
GAMMA

EarliestScanStart and LatestScanStart

These settings control the time when scans are allowed to run. You must set the time in Universal Coordinated Time (UTC). If you want to use these settings, you must use both. If you use only one, the setting will not be applied. The default is to allow scans to run at any time of day.

Example:

[Group X]
EarliestScanStart=04:00
LatestScanStart=23:30

AllowedDays

This setting controls which days of the week scans are allowed to run. The value is a comma separated list of names. Any of the following values can be included in the list:

Name

Meaning

Sun

Sunday

Mon

Monday

Tue

Tuesday

Wed

Wednesday

Thu

Thursday

Fri

Friday

Sat

Saturday

WkE

Weekends (equivalent to 'Sat,Sun')

WkD

Weekdays (equivalent to 'Mon,Tue,Wed,Thu,Fri')

If this setting is not specified, scans are allowed to run on any day.

Example:

[Group X]
AllowedDays=Mon,Wed,Fri
