How To Fix Lag Spikes on Server

I keep getting alerts from the monitoring feature I set up that say the site is experiencing high latency.

Server is node/express.

How do I go about fixing this? I tried profiling my app with --inspect, I also tried the 3rd party tool “Clinic” with different views, I tried looking at my google analytics, but still was unable to find anything useful.

All my resources seem to spike at the same time.

How do i even start thinking about how to solve this problem?

    Hi @skeddtemp,

    It’s expected for the resources to jump at the same time. The reason behind these should be fairly simple. It’s possible you have some cronjob configured at the time of the spikes, or you have a bot crawling your website thus generating a high load.

    If you can find a pattern of when the spikes appear try logging in to your Droplet and caching the spike in real-time and trying to troubleshoot it. See what processes are running, use htop to see what is causing this high load, etc.
