I’ve a 2GB 25GB $10 Digital Ocean droplet. My forum is fairly new so all the figures are tiny, except:
Memory (between 75-80%, and inexplicably jumped to 85% yesterday and remains there). When I installed Discourse I went for the 2GB option rather than setting up swap memory.
Disk usage (78-80%). Once when rebuilding Discourse it ran out of disk space and had to clear some space before I tried again. Is there any way to clear more space (e.g. permanently deleting “deleted” topics)?
At what sort of percentage levels should I look at upgrading the droplet?
