There are 3 kinds of log files:
Any of them can be disabled by setting it to
none in the Configuration.
access.log are enabled.
debug.log is only enabled if debugging is also enabled.
error.log is the
stderr of the netdata daemon and all plugins run by netdata.
So if any process in the netdata process tree writes anything to its standard error, it will appear in the
access.log logs web requests. The format is:
DATE: ID: (sent/all = SENT_BYTES/ALL_BYTES bytes PERCENT_COMPRESSION%, prep/sent/total PREP_TIME/SENT_TIME/TOTAL_TIME ms): ACTION CODE URL
IDis the client ID. Client IDs are auto-incremented every time a client connects to netdata.
SENT_BYTESis the number of bytes sent to the client, without the HTTP response header.
ALL_BYTESis the number of bytes of the response, before compression.
PERCENT_COMPRESSIONis the percentage of traffic saved due to compression.
PREP_TIMEis the time in milliseconds needed to prepared the response.
SENT_TIMEis the time in milliseconds needed to sent the response to the client.
TOTAL_TIMEis the total time the request was inside netdata (from the first byte of the request to the last byte of the response).
