我想要MariaDB监视器monit tools。我的monit script是 ：
check process mariadb_pid with pidfile /var/lib/mysql/db1.pid
check program telnet with path "/root/telnet.sh"
if status eq 99 then exec "/usr/bin/systemctl restart mariadb.service"
并且telnet script是：
#!/bin/bash
cat /root/ips | \
while read host port; do
result=$(bash -c 'exec 3<> /dev/tcp/'$host'/'$port';echo $?' 2>/dev/null)
echo $result
if [ "$result" != "0" ]; then
exit 99
fi
done
ips文件是：
192.168.10.10 3306 192.168.10.20 3306
现在，预计如果 ips 文件中的 mariadb ip1 和 ip2 已关闭，则执行
if status eq 99 then exec "/usr/bin/systemctl restart mariadb.service"
但没有跑步。请查看监控日志。
