How to enable debug log level using "influxd" command

Hi,

The below is the influxdb.conf file:

[meta]
  dir = "/var/lib/influxdb/meta"
  logging-enabled = true

[data]
  dir = "/var/lib/influxdb/data"
  engine = "tsm1"
  wal-dir = "/var/lib/influxdb/wal"
  query-log-enabled = true

[logging]
  level = "debug"

I used the below the command to start influxdb daemon:

/usr/bin/influxd -config /etc/influxdb/influxdb.conf 

but the logs still shows the “info” level log not a debug level; even i configured it.

influxdb_1    | ts=2020-08-26T04:37:21.526252Z lvl=info msg="Executing query" log_id=0OrGI1Ml000 service=query query="SHOW RETENTION POLICIES ON mydb"

Does this work?
/usr/bin/influxd --log-level debug -config /etc/influxdb/influxdb.conf

I’m getting the below error:


influxdb_1    | flag provided but not defined: -log-level

It seems no such option --log-level debug was there with influxd command

Can you confirm you’re using influxdb2 per the tag label on this thread?

Sorry, It seems I’m not using influxdb2.

I’m using the below version

root@influxdb:/opt/influxdb-backup# influx --version
InfluxDB shell version: 1.7.10

All good. Seems it’s called just level in 1.x

Maybe try moving the logging block in your config higher up in the file - perhaps it needs to be set before the enabled parameter gets seen by the loader.

As you said, I’ve moved the logging up in the file but no luck ( still info level logs are coming ).

influxdb.conf

[logging]
  level = "debug"

[meta]
  dir = "/var/lib/influxdb/meta"
  logging-enabled = true

[data]
  dir = "/var/lib/influxdb/data"
  engine = "tsm1"
  wal-dir = "/var/lib/influxdb/wal"
  query-log-enabled = true

Running influxdb deamon

/usr/bin/influxd -config /etc/influxdb/influxdb.conf

logs

influxdb_1    | ts=2020-08-27T06:54:51.521890Z lvl=info msg="Executing query" log_id=0OsfxeCG000 service=query query="SHOW SUBSCRIPTIONS"

That’s very strange. Maybe @Anaisdg can spot what’s missing to get debug logging enabled.

Also, if you’re still on 1.7.x you might want to consider upgrading to the latest 1.8 release

Still I’m getting info level logs.full_config.txt (3.4 KB)

hi, Could you please help me on this issue?

Hi,

Any update on this query?

Are you trying to not show info level logs? Or are you trying to show debug level logs?

debug is more verbose than info, so it will include all info log messages (as well as warn and error messages).

Yes I’m trying to display only debug level logs.

The logging levels aren’t exclusive, so level="debug" means “Show me any messages at level debug or higher”, which is going to include all other level messages.

@mhall119, yes. I’m getting all levels( error, info, warn ). you opened my eyes. Thanks.
