Tomcat monitoring script (monitoring process, test interface, alarm action for sending mail)

Server environment: centos7.2 64-bit tomcat8.5.6

The Tomcat monitoring feature requires a total of two scripts, as follows:
initmonitor.sh

#!/bin/sh#初始化监控脚本相关变量Export tomcat_name=apache-tomcat-8.5.6export tomcat_home=/usr/local/apache-tomcat-8.5. 6 #测试接口访问地址 export WebUrl=127.0. 0.1:8080/yanglao/sysusercontroller/systest  #监控脚本日志路径 export tomcatmonitorlog=/tmp/yanglao/ Tomcatmonitor.logexport [Email protected]# Execute Tomcat monitoring script  #获取当前脚本所在目录baseDirForScriptSelf =$ (CD  "$ (dirname" $ ")"; pwd)  $baseDirForScriptSelf/tomcatmonitor.sh

Pre-Preparation:

1. Installing crontab
2. Configuring the Mail delivery environment

Script Description:

1. Variables used in the configurable script in initmonitor.sh, in addition to the parameter configuration, will call tomcatmonitor.sh in this script, which is called again because the variable set by export is valid only in that Shell and its child shells.
2. tomcatmonitor.sh business logic scripts for Tomcat monitoring

Instructions for use:
1. Place initmonitor.sh,tomcatmonitor.sh two scripts into the server sibling directory (e.g./usr/bin/yanglao)
2. If you want to configure the script corresponding variable, please edit initmonitor.sh, do not need to change the can skip this step
3. Use crontab to set timed execution initmonitor.sh:
1) # CRONTAB-E
2) Insert /5 * * */usr/bin/yanglao/initmonitor.sh
3) #systemctl Reload Crond
#systemctl Restart Crond
After that, the script runs and starts detecting tomcat.

Detection range: Tomcat process shutdown, System interface inaccessible
Alarm action: Send mail to initmonitor.sh settings and restart Tomcat.
After rebooting, the Tomcat is re-detected, the detection is running normally, sending an alarm to close the message
