# ----------------------------------------------------------------------
#    create loadbalancer group, or use conn_eu.get_all_security_groups()
#    if it already exists.  replace  "your.private.ip" with your private
#    IP address, as we're restricting SSH access to your IP address.

# update, get state, repeat

# eventually instance.state becomes running.  instance.public_dns_name
# contains that hostname you need to connect to as you've done before.

# .. otherwise consider putting these two in /etc/rsyslog.conf instead:
$ModLoad imudp
$UDPServerRun 514
 
# ..and in any case, put these two in /etc/rsyslog.d/haproxy.conf:
local0.* -/var/log/haproxy_0.log
local1.* -/var/log/haproxy_1.log

# ----------------------------------------------------------------------
#     Save, close the file
# ----------------------------------------------------------------------

# ----------------------------------------------------------------------
#     Execute:
# ----------------------------------------------------------------------
restart rsyslog

# to see HAProxy logs, execute the command below.  Of course, there will
# not be anything there for now.
tail -f /var/log/haproxy*.log

# ----------------------------------------------------------------------
#     Set up log rotation in /etc/logrotate.d/haproxy:

    weekly

    notifempty
    compress
    delaycompress
