[GitHub] [apisix] zjclyz opened a new issue, #10142: help request: How to locate apisix memory footprint issues
zjclyz opened a new issue, #10142:
URL: https://github.com/apache/apisix/issues/10142
### Description
Problem: I recently built a gateway with apisix, which is currently in the testing phase without much traffic (QPM is about 100/min), and noticed that the gateway's memory usage is exaggerated, as shown in the picture（Machine specification: 8c 16g）:

Plugins: opentelemetry, gzip,uri-blocker,proxy-rewrite,response-rewrite,log-rotate,real-ip, and a few simple plugins I wrote based on business requirements
Claim: Have you encountered this situation where there is little traffic and the gateway's memory footprint goes up and down? apisix What is a more convenient way to perform memory diagnostics to determine this kind of memory problem?

@zjclyz try to disable the Prometheus plugin.
And if the issue keeps still, try the master branch.

APISIX have Lua part and c part, the first step is to distinguish whether the problem is with c or lua, it's a bit complicated, so i think the easy way is to remove the code you added, it the problem still exists, seek the community for help

I didn't find out exactly why, but I rewrote a plugin I wrote and it worked unexpectedly I didn't understand why, does apisix have a simple enough means of locating memory leaks like golang's prof
