Hi,

Just now I have started working on discovery so While running the discovery I have noticed the following two points:

  • Before running the discovery I have stored all the credential in SNOW and ran it.But I have noticed it will try all username and pass and get the valid one and discover the machine.So it takes much time.Is there any way we can speed up this process by doing some kind of tagging.
  • While doing discovery it discovers all the cameras and it will still try the credential.But there is no credential for this.It will just update logs with errors and we need to confirm the local resource what is it and exclude it.But may be in future that device is down and IP is getting used for the server.It can be a problem.

Can someone please advise on these points and guide me.I am looking into discovery pattern not sure is it going help or not?

Thanks,

Vimal

Hi Vimal,


Is the issue that you have some cameras that cannot be discovered but the IPs are dynamically allocated via DHCP and other devices which are discoverable may get IP from the same pool? Meaning you cannot exclude the cameras from the discovery based on their IP addreses?

Hi,



I think I have found something.What I was looking for to exclude device by their type not by IP.If we exclude by the IP, may be this device has been taken down and IP is used for any other device that we want to discover.But as it is in excluded list It will not be discovered.So I think under Discovery Definition --> Configuration Console I can define that.





Thanks,


Vimal
