The management object name of the peer gateway for this Permanent Tunnel. Since permanent tunnels are typically reserved for a handful of critical, always-needed links, this readable name is what lets an admin immediately recognize an alert as concerning one of those specific high-priority always-up connections rather than an ordinary on-demand site tunnel. Example: an alert citing a permanentTunnelPeerObjName naming a disaster-recovery site gateway immediately flags it as the always-up DR link, warranting faster escalation than a routine branch tunnel would.
