I'm running a Node/Meteor/Mongo app on Ubuntu (on a Digital Ocean 1GB droplet), and I've been seeing some weird disk I/O spikes, which are then followed by CPU spikes:
I was wondering:
- If that pattern corresponds to any known problem?
- What tools or strategies I could use to figure this out?
I'm pretty new at server and performance monitoring, so any help will be appreciated, no matter how basic!
