33.6 Refreshing Device Inventory
Device inventory is broken down into three areas:
Š
Software
Š
Hardware
Š
System (disk size, usage, and operating system information)
Inventory data is refreshed in three ways:
1. At client (zmd) start up.
Š
The device sends hardware and system information to the server where the device is
registered.
Š
A new software hash is calculated to check if there has been a change, for example, if a
new package or bundle has been installed. If the hash has changed, the device sends the
new software inventory to the server where the device is registered.
2. When new software in installed on a client, that software inventory information will be sent to
the server immediately.
3. At a scheduled refresh, which refreshes data as described in the client start up above.
Device inventory is refreshed at start up and then every twenty-four hours by default. This schedule
cannot be directly changed on the server side, but it can be changed on the client side using
rug
refresh-interval-hardware
time_in_second s,
rug refresh-interval-
software
time_in_seconds , and
rug refresh-interval-system
time_in_seconds . If you
want to change the inventory refresh schedule for multiple managed devices, you can use a Remote
Execute policy. For more information, see
Section 16.6, “Remote Execute Policy,” on page 159 .
IMPORTANT: The Device Refresh Schedule setting does not affect refresh inventory information.
