Narrative:

On departure climb; we received ECAM message engine 1 oil filter clog. We complied with the ECAM instructions and monitored the system. Approximately 30 minutes later; we received ECAM msg eng 1 lo oil press. Oil pressure was 80 psi and dropping when we performed the ECAM action. We shut down engine one in accordance with the procedure. Oil pressure was 50 psi at the time of the shutdown. The engine shut down normally. I [advised] with center and asked for a turn direct to [a nearby alternate]. I assigned the first officer flying duties and proceeded to communicate with the crew; passengers; and company. At the time of the shutdown; we [were] at FL300 and cruising at M.78. There were no indicators such as noise or vibration; but the flight attendants reported loud noises at about the same time as we received the ECAM message. The descent was uneventful and ATC was extremely professional and helpful. We initially received vectors for the ILS but I requested to go [a different] runway xxc; which is 2;000 feet longer because we were going to have to perform an overweight landing. Approach and landing were uneventful. We touched down with a descent rate of less than 100 fpm and stopped normally. I cleared the runway and was met by arff which inspected the engines and brakes at my request. Once released by the arff commander; we taxied to the gate. The passengers deplaned the aircraft normally. The fire chief inspected the engine and reported that the site gauge for the oil showed it was full. The oil quantity indicator also showed there was greater than 15 quarts. It appears the issue was a completely clogged oil filter.
