On distributions with systemd, ScyllaDB logs are written to the systemd journal. You can retrieve log entries with the journalctl command.
Listed below are a few useful examples.
get logs generated by the “scylla” user:
journalctl _UID=`id -u scylla`
get logs generated by the “scylla” command:
journalctl _COMM=scylla
filter only ScyllaDB logs by priority:
journalctl _COMM=scylla -p err..emerg
journalctl _COMM=scylla -p warning
filter only ScyllaDB logs by date:
journalctl _COMM=scylla --since="2013-3-16 23:59:59"
journalctl _COMM=scylla --since "2015-01-10" --until "2015-01-11 03:00"`
journalctl _COMM=scylla --since yesterday
filter only ScyllaDB logs since last server boot:
journalctl _COMM=scylla -b
On Ubuntu 14.04, ScyllaDB writes its initial boot message into /var/log/upstart/scylla-server.log
.
After ScyllaDB has started, logs are stored in /var/log/syslog
. ScyllaDB logs can be filter by creating a rsyslog
configuration file with the following rule (for example, in /etc/rsyslog.d/10-scylla.conf
)
:syslogtag, startswith, "scylla" /var/log/scylla/scylla.log
& ~
And then creating the log file with the correct permissions and restarting the service:
install -o syslog -g adm -m 0640 /dev/null /var/log/scylla/scylla.log
service rsyslog restart
This will send ScyllaDB only logs to /var/log/scylla/scylla.log
Starting from ScyllaDB 1.3, ScyllaDB Docker, you should use docker logs
command to access ScyllaDB server and JMX proxy logs
