Get a chain gauge, it will tell you when to replace your chain along with advice from YT Park Tool videos. Normally every 2k kms but varies with wear and lack of maintenance. If you do 8k a year, they you're probably better off with a belt transmission, a Rohloff hub and a pair of Marathon Mondial tires. They're heavy but they can last 10k. And rim brakes, the pads for them are cheaper and last way longer. I still have Maguras on my touring bike and Marathon Supremes.
