tzssangglass commented on issue #5837: URL: https://github.com/apache/apisix/issues/5837#issuecomment-1173262871 > I found that nginx adopts a way of pre-allocating memory for shared DICT, the smallest granularity is page, ranther than allocat per use. The value of `ngx.shared.DICT.capacity` is accurate, but `ngx.shared.DICT.free_space` is the value left after the acquired pre-allocated memory, so there is a certain inconsistency in fine-grained `ngx.shared.DICT.free_space` accurate. Is there some docs or code that explain this? This is useful info. -- This is an automated message from the Apache Git Service.

tzssangglass commented on issue #5837: URL: https://github.com/apache/apisix/issues/5837#issuecomment-1080100342 we can use `ngx.shared.DICT.capacity` and `ngx.shared.DICT.free_space` to monitor a `ngx.shared.DICT`? -- This is an automated message from the Apache Git Service.

tzssangglass commented on issue #5837: URL: https://github.com/apache/apisix/issues/5837#issuecomment-1079713346 I changed my mind and I think it's a meaningful enhancemen. Perhaps we can first monitor the nginx.shared.DICT that is used by APISIX, and next we allow users to monitor a custom nginx.shared.DICT (or read the used nginx.shared.DICT directly from the configuration file). cc @spacewander -- This is an automated message from the Apache Git Service.

tzssangglass commented on issue #5837: URL: https://github.com/apache/apisix/issues/5837#issuecomment-997520329 It seems to be quite difficult, and if you use the ngx.shared.DICT API to monitor it, it will lose performance. refer to: https://github.com/openresty/lua-nginx-module#ngxshareddictcapacity -- This is an automated message from the Apache Git Service.
