Narrative:
At 32;000 ft. I observed the right engine vib (vibration) gauge spike from .2 to 1.4 trending toward the yellow caution range along with an accompanying vibration in the floorboard. The first officer and I reviewed the QRH (quick reference handbook) for abnormal engine fan vib indication and realized that if such conditions worsened that an intentional engine shut down may be needed. I contacted the flight attendants and asked them if they noticed anything different in the cabin and the aft flight attendant said it was exceedingly loud with a stronger than usual vibration coming from the right side of the aircraft. I notified center control that we would request runway xx as a straight in approach due to an abnormal engine indication but that both engines were still producing power and no [priority handling] was needed. Upon arrival in ZZZ; we were met with arff (aircraft rescue and fire fighting) equipment and personnel and taxied to the gate without incident.
