Open Stack

I have checked the mysql limit and it's very high and usage is way below
the limit using them. It's a very small deployment in the lab.

Following is the docker container running that check

(mariadb-clustercheck)[root at kolla-infra-1-2 /]# ps aux
USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root           1  0.0  0.0   2632   924 ?        Ss   Apr04   0:00
dumb-init --single-child -- kolla_start
root           7  0.0  0.0  10280  4760 ?        S    Apr04   8:19 socat -d
-lf/var/log/kolla/mariadb/mariadb-clustercheck.log
tcp-l:4569,fork,reuseaddr,bind=10.30.50.2 EXEC:clustercheck
root     2070140  0.0  0.0   7624  4240 pts/0    Ss   18:08   0:00 bash
root     2070999  0.0  0.0  10060  1596 pts/0    R+   18:09   0:00 ps aux

When i run manually i got successful reply

(mariadb-clustercheck)[root at kolla-infra-1-2 /]# clustercheck
HTTP/1.1 200 OK
Content-Type: text/plain
Connection: close
Content-Length: 32

Galera cluster node is synced.

Everything looks ok so far. Not sure if I should ignore that error message
or consider it bad.
