When we reached top of climb I started recording our fuel and doing the RVSM check. The First Officer (FO) opened up the status page on his Multi-Function Display (MFD) and as I glanced up I noticed that the System 2 Emergency Accumulator was low and had him bring the page back. When he brought the page back up the pressure was at 2300PSI. I opened the Hydraulic Synoptic page on my MFD and observed the quantities and pressures of all the systems. Hydraulic System 2 was at 70% quantity and 3000PSI. We monitored the situation [and] noticed every 15-20 minutes the System 2 Emergency Accumulator would drop by about 50PSI; right about that same time we would get about a 2% drop in Hydraulic System 2 quantity. I called Dispatch and spoke to Maintenance and they said to monitor it and write it up on the ground. With the integrity of the system in question; and not knowing how the situation would progress; especially once the system was loaded with flight control movements; brakes; spoilers; and reversers; I informed the Dispatcher as a precaution. The FO and I reviewed the complete loss of Hydraulic System 2 QRH and prepared for that just in case. By the time we were configured on final Hydraulic System 2 quantity had dropped to 56% and the Emergency Accumulator for system 2 had fallen to 1950PSI. We landed without incident and taxied to the gate under our own power.
EMB-175 Captain reported noticing that hydraulic system #2 was losing quantity. Flight continued to destination and landed with quantity at 56%.
