How to get here in the StoreGrid Web Console?
  In the top menu, select: "Administration-> Advanced Options". In the Advanced Options page click on the Discovery Configuration Icon on the left hand side.

This page is meant for configuring the automatic discovery feature in StoreGrid. “Discovery” is done to discover other StoreGrid peers in the subnet and also to check the status of other StoreGrid peers.
The following are the types of discovery done and you can enable/disable them and also change the time interval for each type of discovery. Note that StoreGrid will discover other StoreGrid peers only within a subnet. You will have to manually add StoreGrid peers in other subnets from the menu item "Administration->Add Peer".

Multicast Discovery - StoreGrid uses the multicast ports 6363 and 6364 to send and receive multicast requests to discover other StoreGrid peers within the subnet. This is one of the fastest ways of discovering other StoreGrid peers provided multicasting works inside the subnet. This discovery is done every minute, by default. You can disable/enable this discovery or change the time interval as required.

TCP Discovery - This is a more comprehensive discovery mechanism where StoreGrid shares peer information between each other. This sharing is done only within ‘already discovered’ StoreGrid peers. Hence, no scanning of invalid IP addresses is done. This discovery cannot be disabled and by default it is run every 5 minutes. You can change the time interval of this discovery to a maximum time interval of 60 minutes.

UDP Network Scanning - This scans for the UDP port 32006 inside the subnet to detect the presence of any StoreGrid peer. This is done every minute by default. You can enable/disable this discovery or change the time interval as required. By default, UDP Network Scanning is disabled in StoreGrid.

TCP Network Scanning - This scans for the TCP port 32005 inside the subnet to detect the presence of any StoreGrid peer inside the subnet. This is done every 5 minutes, by default. Note that before a TCP port scan is done, StoreGrid actually does an ICMP ping to collect valid IP addresses. You can enable/disable this discovery or change the time interval from this user interface. By default TCP Network Scanning is disabled in StoreGrid.

NOTE :

1. If a StoreGrid peer is not discovered automatically, you can add it manually from the Add Peer page. StoreGrid will discover peers only within a subnet. StoreGrid Peers outside the subnet have to be added manually. The manually added StoreGrid peer will show up only in the web console of the StoreGrid peer which added it.
2. You can delete any StoreGrid peer from the Delete Peer page. The delete will take effect only in the web console of the StoreGrid peer that deleted the peer.
