OID Database?

Where is the database that shows what OID’s are given to NVT’s?

I guess you mean the database of VTs within the GVM so moving to the correct https://community.greenbone.net/c/gse category.

On the system/version I use, you could use a script like this to get some insight into the OIDs:
/var/lib/openvas/plugins# grep script_oid *.nasl | cut -d: -f2 | sort | uniq


I am using psql and can see an OID entry in table “nvts”. Maybe this is what you are looking for?
