I have a staging application (thank goodness its not in production yet), and it started crashing my server because it was using too much memory. However, I’m not really sure why since I haven’t made changes for over a long time.
In my logs it says:
Aug 15 06:58:17 PM [os_mon] cpu supervisor port (cpu_sup): Erlang has closed
Aug 15 06:58:17 PM [os_mon] memory supervisor port (memsup): Erlang has closed
Where should I be looking to figure out the reason causing this?
Where Next?

Just wanted to drop an update. Found out that someone decided to upload a ton of items into our staging and graphql was basically pulling all the records and led to not having enough memory. Now I have to figure out how to improve on this…
Also, thank you everyone for helping me. I appreciate all the comments!

Ah sorry, I meant it only for errors, yeah. I’m investing in writing code for ingesting anything and everything in OpenObserve lately, though it doesn’t have the ready-and-baked dashboards that f.ex. NewRelic has.

Yeah, I like Rollbar too, although when I last used it it was just error reporting, not APM. I really like the “RSQL” or whatever they call it, their query language/tool.
dimitarvp
Rollbar works really well too, and it’s quite cheap.
I like AppSignal as well btw.

Honestly, I find the NR UI a baffling mess of confusion
I’m an AppSignal fanboy.

Got it! I think New Relic might help me out with this. I’ll go through some testing tomorrow to see what I find.

Whatever you can use, observer, LiveDashboard, maybe even a system tool, as long as you can understand if it is a spike or there is a permanent leak.

For low RAM VMs, you may want to try to run in 32 bit to conserve memory. I have a blog post on this, albeit with fly.io:

Where is the profiler? are you referring to the Processes tab in LiveDashboard?

I actually have New Relic on this staging machine. I tried looking around, but didn’t notice anything strange. I was rushing to fix it so might have need to look closer. I’m also not too familiar with New Relic, which page would you recommend that I look at?
