用于通过电子邮件警报进行服务监控并防止重复警报的 bash 脚本

我有一个计划每 5 分钟运行一次的脚本来检查两项服务，如果发现任何服务状态关闭，则会发送电子邮件。其工作正常。

但问题是我希望它在服务上线时也发送 UP 警报。我可以添加行来发送电子邮件，但它会重复向上警报。我如何添加向上警报功能，但它应该只发送一次警报（就像向下警报一样）

#!/bin/bash
if pgrep "mysql" > /dev/null
then
    echo "MYSQL Running"
    rm -f /var/run/.mysql_mail_sent
else
    echo "ALERT: mysqld Stopped."
    if [ ! -f /var/run/.mysql_mail_sent ]; then
echo "Sending MYSQL DOWN Email..."
echo "DOWN ALERT! sending email" > /var/run/.mysql_mail_sent

    fi
fi

if pgrep "radiusd" > /dev/null
then
    echo "radiusd Running"
    rm -f /var/run/.radiusd_mail_sent
else
    echo "ALERT: RADIUSD Stopped"
    if [ ! -f /var/run/.radiusd_mail_sent ]; then
echo "RADIUSD DOWN: Sending Email."
echo "DOWN ALERT! sending email" > /var/run/.radiusd_mail_sent
    fi
fi

好吧，我终于成功了。 BASH 更快并且不需要任何第三部分工具。 [下午 4:43 更新]

#!/bin/bash
# Scheduled Script to check linux service status after every 5 minutes.
# If found stopped, send sms or email Alerts, but donot repeat it untill next status change.
# Syed Jahanzaib


# Run script with service name like
# ./status.sh mysqld


# Check if no service name is given
if [ "$1" == "" ]; then
echo No service name have been provided.
echo Usage exmaple:
echo
echo -e "./status.sh mysqld"
echo
fi
