manually adding computers already with agents

[ewong 6]

Hi,

In my confusion, I removed some systems (from the Windows group) that I really shouldn't have.   In realizing my mistake, I waited until the systems were up to ensure they were automatically added to the list again when their agents reported in.

However, after waiting for an hour, the list of computers still lacked those missing systems.   So I added them manually via their local fqdn.  Even after half an hour, their status still show the circle.

So I've got a few questions regarding this scenario.

1) Assume I didn't manually add those systems,  how long will those agents report back to the ESMC server?

2) Now that I've manually added those systems, how long will those agents be 'discovered'?

I really don't want to go into those systems and remove the AV and Agent and redeploy them. 

Thanks

Edmund

Apparently the agents were trying to connect.  Seems as if they can't.  Troubleshooting this...

My fault.  Please ignore.

Reasoning why it's failing:  The whole certificate setup was fubar'd thanks to my incompetence in selecting the right certificate.

Just to summarize for others:

• In case of device removal, it should be automatically re-created upon next connection. In case of ESMC7+ there might be just "question" for administrator in ESMC console in case there is suspicion that device has different HW.
• Creating device manually won't resolve this issue. ESMC uses internal identifiers for pairing devices, so even if there are multiple records with the same name, AGENT will be properly paired. In other words, name of device in console is irrelevant when pairing existing installations.
• In case device is not re-created until midnight (local time of ESMC installation) it might happen that specific data is lost for this device. There are regular cleanups running at that time and data for non-existing devices is purged. This includes mostly event-related records, especially those received from ESET products (detection related logs, firewall logs ...)
