How to specify the size of this parameter value in lua_shared_dict prometheus-metrics?

[shihuncl]

Description

Prometheus collects apisix indicator data, and the shared memory of prometheus-metrics is insufficient. The deployment method of apisix is ​​through helm. How do I modify this value?

Change the position on the picture to
customLuaSharedDicts:
- name: prometheus-metrics # Lua shared dictionary name
size: 100m #Set the shared dictionary size to 100M.
Is this correct?

Environment

• APISIX version (run apisix version):3.9

[shihuncl]

values.yaml文件中添加配置
customLuaSharedDicts:
- name: prometheus-metrics
size: 50m
然后执行helm upgrade apisix-rebuild -n apisix ./apisix-using 命令
如下报错2025/01/10 20:06:58 [emerg] 1#1: the size 52428800 of shared memory zone "prometheus-metrics" conflicts with already declared size 10485760 in /usr/local/apisix/conf/nginx.conf:96
nginx: [emerg] the size 52428800 of shared memory zone "prometheus-metrics" conflicts with already declared size 10485760 in /usr/local/apisix/conf/nginx.conf:96

configMap没有指定prometheus-metrics值的大小，还有哪里指定了呢？我该怎么去修改这个配置的大小？

[wklken]

the customLuaSharedDicts is for custom plugin only custom_lua_shared_dict

prometheus-metrics is under lua_shared_dict, which can't be configured in the values.yaml currently.

在apisix文件下面nginx配置文件中修改lua_shared_dict的大小，如果是docker部署或者K8S部署的时候项目重启了这个修改好的值又被还原了默认值了
