Can't change log level

Hello!
Grafana are installed from rpm.
I changed log level in /etc/grafana/grafana.ini:
[log]
# Either “console”, “file”, “syslog”. Default is console and file
# Use space to separate multiple modes, e.g. “console file”
;mode = console file

# Either "trace", "debug", "info", "warn", "error", "critical", default is "info"
;level = debug

# optional settings to set different levels for specific loggers. Ex filters = sqlstore:debug
;filters = context:trace


# For "console" mode only
[log.console]
;level = debug

# log line format, valid options are text, console and json
;format = console

# For "file" mode only
[log.file]
;level = debug

# log line format, valid options are text, console and json
;format = text

But after Grafana restart logging still with info level.

try removing the ; a the start of the line, it comments the line out .by default all options are commented out

Thank You!
But for logger=context still lvl=info.
What is the best method to view and log REST requests from Grafana and json responce from my datasource?

try context:debug

dont think trace is a valid level anymore

I solved the problem by making the change under /usr/share/grafana/conf/defaults.ini
then restarted grafana.
