Method: Sensu::Server::Process#update_leader_lock

Defined in:
lib/sensu/server/process.rb

#update_leader_lock ⇒ Object

Updates the Sensu server leader lock timestamp. The current leader ID is retrieved from Redis and compared with the leader ID of the current process to determine if it is still the Sensu server leader. If the current process is still the leader, the leader lock timestamp is updated. If the current process is no longer the leader (regicide), ‘resign_as_leader()` is called for cleanup, so there is not more than one leader.
