Vulnerability Detection is not working on some agents

[soro pizza]

Hello,

I enabled the Vulnerability Detection module so I could use it on my servers, but some of them are not showing up on the dashboard, inventory, are generating events. I already checked things like syscollector and vulnerability detection configurantion on ossec.conf of both my manager and my agent. Its important to mention that i have other servers that are working normally, and that the dbs for each agent are not empty on /var/ossec/queue/db

It seems like i don't have the inventory data of my servers.

Greetings in advance.

Good day Soro.

Just to be sure, Could you confirm the following for the affected agents:

Do the problematic agents appear as "Active" under Management - Agents? this is to discard if there is a communication problem between the agent and the server.

Are these agents generating regular events and alerts normally (for example, in Threat Hunting or Security Events) and only missing the Vulnerability Detection data? Or are they not showing up in any module of the dashboard at all?

When you open the specific agent view and go to the Inventory Data section, do you see information about hardware, OS, packages, and network interfaces? Or is it completely empty?

Could you restart and share the output of the following command from one of the affected agents:

tail -100 /var/ossec/logs/ossec.log

Thanks.
