Summary

Details of the parameters available when setting the coverage for a question or action.

Coverage parameters

When the Tachyon agents start and connect to Tachyon they provide some basic information about the devices they are running on that enables Tachyon to determine the coverage of a question and be selective about which devices get asked.

The information returned enables the coverage to be limited according to the following attributes:

AttributeDescription
Device (FQDN)Limits coverage according to complete or partial matches for the provided text found in the device's FQDN
Operating SystemLimits coverage according to the Type, Name and Version number of the device's Operating System
Tachyon Agent VersionLimits coverage according to the device's installed Tachyon Agent version
HardwareLimits coverage according to the device type, model, virtual platform or installed RAM
Last bootLimits coverage according to whether the last time the device was rebooted was before or after a given date and time
TimezoneLimits coverage to devices with the selected timezone set
TagsLimits coverage to devices where the Tachyon Agent has the selected tag name and tag value tag set.

You can also choose to limit coverage using a device list, using the Device List (FQDN) attribute, located below the other coverage attributes under a separator line. Device lists are mutually exclusive to the other coverage attributes you cannot mix between the attributes above and below the line.
