When does last_discovered get updated?

[mb27]

Some classes get their "last_discovered"   (most recent discovery) attribute updated, some don't.

What updates last_discovered ?

Why do some classes get this updated, why do others not?

Our users want to see the "most recent discovery"   date and time. It's a confidence thing. Is the CMDB   up to date? Or have we just got a lot of old information that hasn't been updated for some time? Two recent upgrades, Windows 2008 and Eureka had the huge negative effect on discovery. The users could see that things were not being discovered after the Eureka upgrade because the "most recent discovery" attribute showed dates in the past, that corresponded to the day we upgraded ServiceNow.     When we rolled out the Windows 2008 upgrade, we could see servers being discovered as they had the most recent discovery field updated. But other stuff (web sites in pariticular) didn't get the most recent discovery field updated. In fact they weren't being discovered for a number of reasons, but we kept on trusting out o9f date information.

is there any down side to me adding the following to a sensor:

current.last_discovered = gs.nowDateTime();

Hi 

I am having the same issue. In my case, The Server and database instance are getting modified with the Most recent discovery date but whereas Database catalogs are not getting updated with the most recent discovery date but some Database catalogs are updated with Most Recent Discovery.

Can you let me know under which circumstances the Database catalog MRD is getting updated.

Thanks,

Nithya
