InfluxDB writes log output, by default, to
stderr. Depending on your use case, this log information can be written to another location.
If you run InfluxDB directly, using
influxd, all logs will be written to
stderr. You may redirect this log output as you would any output to
stderr like so:
If InfluxDB was installed using a pre-built package, and then launched as a service,
stderr is redirected to
/var/log/influxdb/influxd.log, and all log data will be written to that file. You can override this location by setting the variable
STDERR in the file
Note: On OS X the logs, by default, are stored in the file
For example, if
all log data will be discarded. You can similarly direct output to
stdout by setting
STDOUT in the same file. Output to
stdout is sent to
/dev/null by default when InfluxDB is launched as a service.
InfluxDB must be restarted to pick up any changes to
Starting with version 1.0, InfluxDB on systemd systems will no longer write files to
/var/log/influxdb by default, and will now use the system configured default for logging (usually journald). On most systems, the logs will be directed to the systemd journal and can be accessed with the command:
sudo journalctl -u influxdb.service
Please consult the systemd journald documentation for configuring journald.
You can use logrotate to rotate the log files generated by InfluxDB on systems where logs are written to flat files. If using the package install on a sysvinit system, the config file for logrotate is installed in
/etc/logrotate.d. You can view the file here.
