Log messages from external check script to rsyslog

Help!
1

I would like to print some log messages from the external check script to rsyslog.
For now, I use “echo” in my external-check.sh script but it does not show up the echo messages. It only shows the haproxy log messages.
Is that possible?

Any answer, please? thank you

Here is the configuration. Can someone take a look please?

The content of haproxy.cfg:

global
    log 127.0.0.1 local0
    external-check
    insecure-fork-wanted

defaults
    mode                    http
    log                     global
    option                  httplog
    timeout queue           1m
    timeout connect         10m
    timeout client          1m
    timeout server          10m
    timeout http-keep-alive 10s
    timeout check           10m
    timeout tunnel          10m
    maxconn                 2048

frontend pa
    bind *:443
    use_backend back-servers

backend back-servers
    option external-check
    option log-health-checks
    external-check command /etc/haproxy/external-check.sh
    server PA-A xxx check inter 30s fall 6 rise 1 ssl verify none
    server PA-B xxx backup check inter 30s fall 6 rise 1 ssl verify none

the content of /etc/logrotate.d/haproxy

$ModLoad imudp
$UDPServerRun 514 
$template Haproxy,"%msg%\n"
local0.* -/var/log/haproxy.log

example of log output:

 Health check for server back-servers/PA-A failed, reason: External check timeout, code: 1, check duration: 30009ms, status: 0/1 DOWN.
 Health check for server back-servers/PA-A failed, reason: External check error, code: 1, check duration: 738ms, status: 0/1 DOWN.
 Health check for backup server back-servers/PA-B failed, reason: External check timeout, code: 1, check duration: 30022ms, status: 0/1 DOWN.
 Health check for backup server back-servers/PA-B failed, reason: External check error, code: 1, check duration: 1590ms, status: 0/1 DOWN

As you can see there are no printed messages of my “echo”(s) that I have added to the external check script
