<![CDATA[node discovery poll]]>would it be possible to add a manual discovery poll on a subnet? similar to a manual node poll?
i.e. (EntireNetwork->(zoneUIN)->subnet/mask) rightclick -> poll -> discovery

Along with a Hook::DiscoveryPoll script that could be called even if no new nodes are added.  This way a subnet-customattribute could be updated with a last run date/time similar to Alex's configuration poll example.

Thx.

There are hook for topology poll (it's not created by default for some reason, should be called Hook::TopologyPoll), but not for discovery poll. I'll add discovery poll hook in next release.

I maybe a little thick......would i create a new script called Hook::DiscoveryPoll or add that into one of the existing Hook:: scripts?

I currently have:
11 - Hook::StatusPoil
12 - Hook::ConfigurationPoll
13 - Hook::InstancePoll
15 - Hook::CreateInterface
16 - Hook::AcceptNewNode

for(o : GetObjectParents($node))
{
   if (o->type == 1)
   {
      SetCustomAttribute(o, "lastDiscoveryPoll", time());
   }
}

As far as existing hook scripts ...I don't see one that would have access to the subnet object (at least not in the comments).

Hook script already exist - you can use it to update attributes on all subnets where current node belongs.

As to when to do the hook, either at the beginning of the process or the end, i guess it doesn't matter.  what i would be looking to do is set a custom attribute with a last run date/time, whether or not it found anything new.

It is possible to add discovery poll menu on subnet object, but all it can do is to start discovery polls on each node within subnet.
When exactly you want discovery poll hook to be called?

Victor
