Gives the Check Point management object name, as configured in the management console, for the peer gateway of this tunnel. This human-readable name is what makes a long list of tunnel rows actually navigable during an incident, since matching an alert to a named branch gateway is far faster for an on-call engineer than matching it to a bare IP address they'd have to look up. Example: an alert reporting a down state for a tunnel whose tunnelPeerObjName names a specific branch office tells the on-call engineer immediately which office lost VPN connectivity without needing to cross-reference an IP against a site list.
