To expose context flags through diagnostic endpoint `/debug/metrics/flags`. The current `/debug/metrics/cmdline` only provides the command run by user. In the case when user runs Erigon using config file, `cmdline`’s info does not truly reflect the ‘launch setting' and flags set that Erigon is running on. ## Example ### Command ``` erigon --datadir /tmp/data --config test.yaml ``` ### Pseudo config file (in yaml) ``` datadir : '/tmp/data' chain : "sepolia" http : true metrics: true private.api.addr : "localhost:9090" http.api : ["eth","debug","net"] ``` ### Output ``` SUCCESS chain=sepolia config=test.yaml datadir=/tmp/data http=true http.api=eth,debug,net metrics=true private.api.addr=localhost:9090 ```
