Xymon say "No port checks defined", but it configure to check in analysis

Hello 

On my x-www-browser i have 
   xymon-cgi/svcstatus.sh?HOST=totomysql02&SERVICE=ports

says : "No port checks defined" and "WARNING: Flapping status"

On xymon server's analysis.cfg 
HOST=totomysql02
        PROC /usr/sbin/mysqld     1 1
        PORT "LOCAL=%([.:]3306)$" state=LISTEN TEXT=mysql3306$


My conf seem ok (still in xymon server) 
/usr/lib/xymon/server/bin/xymond_client --dump-config | grep
vdmztoptmysql02 | grep 3306 

PORT local=%([.:]3306)$ state=LISTEN min=1 color=red HOST=totomysql02
TEXT=mysql3306 (line: 390)


on xymon server's /var/log/xymon/xymond.log
2020-01-23 15:45:59.822981 Flapping detected for totomysql02:ports - 5
changes in 600 seconds


1/ why "Flapping detected" 
2/ why still "No port checks defined"
