1.前言

???? 前段時間搭建了一套Nagios監控服務，心血來潮想自己寫一個腳本，拓展Nagios插件來監控公司的weblogic服務。

環境：weblogic10.3.3.0 、 CentOS6.5

1.首先介紹一些用命令行監控weblogic的方法

??? 對于Weblogic運行狀況的獲得，我們是通過命令行的方式實現的，通過調用Weblogic的weblogic.Admin類實現的。既然要調用類，就要把/home/weblogic/Oracle/Middleware/wlserver_10.3/server/lib/weblogic.jar包配置導環境變量中。我通過修改原來配置JDK的環境變量中的CLASSPATH.編輯/etc/profile文件，
export CLASSPATH=.:/usr/java/jdk1.6.0_21/lib/dt.jar:/usr/java/jdk1.6.0_21/lib/tools.jar:/home/weblogic/Oracle/Middleware/wlserver_10.3/server/lib/weblogic.jar

1.1 證實weblogic server 是否正常

java weblogic.Admin -url t3://127.0.0.1:6088 -username weblogic1 -password weblogic1 PING count byte

返回結果：

1.2 查看weblogic server的版本

java weblogic.Admin -url t3://127.0.0.1:6088 -username weblogic1 -password weblogic1 VERSION

返回結果：

還有一種方法：java weblogic.version | grep -m 1 "."

weblogic.version | grep -m 1
1.3 獲得server的運行狀態

java weblogic.Admin -url ${URL} -username ${USER_NAME} -password ${PASS_WORD} get -pretty -mbean "${DOMAIN_NAME}:Location=${SERVER_NAME},Name=${SERVER_NAME},Type=ServerRuntime”

我的機器上的執行命令：

java weblogic.Admin -url t3://localhost:6088 -username weblogic1 -password weblogic1 GET -pretty -mbean "hb_circfnl_dom:Location=AdminServer,Name=AdminServer,Type=ServerRuntime"

返回結果：

1.4獲得JDBC Pool運行狀態

$ java weblogic.Admin -url ${URL} -username ${USER_NAME} -password ${PASS_WORD} GET -pretty -mbean "${DOMAIN_NAME}:Location=${SERVER_NAME},Name=${POOL_NAME},ServerRuntime=${SERVER_NAME},Type=JDBCConnectionPoolRuntime"

我的執行命令：

java weblogic.Admin -url t3://localhost:6088 -username weblogic1 -password weblogic1 GET -pretty -mbean "hb_circfnl_dom:Location=AdminServer,Name=circDataSource,ServerRuntime=AdminServer,Type=JDBCConnectionPoolRuntime"

返回結果：

2.利用1.3和1.4的方法根據Nagios Plugin API規則編寫自己的shell實現腳本。。具體的shell腳本如下：

check_weblogic.sh

#! /bin/bash#check_weblogic.sh --jdbcpool url username password domainname servername poolname #check_weblogic.sh --server url username password domainname servername# -H host -p port -v "--type=<[jdbcpool|server]> --username username --password password --domain domainname --server servername [--pool poolname]"PROGNAME=`basename $0` PROGPATH=`echo $0 | sed -e 's,[\\/][^\\/][^\\/]*$,,'` REVISION=`echo '$Revision: 1749 $' | sed -e 's/[^0-9.]//g'`. $PROGPATH/utils.shprint_usage() {echo "Usage:"echo " $PROGNAME -H host -p port -v --type [jdbcpool|server] --username username --password password --domain domainname --server servername [--pool poolname] " echo " $PROGNAME --help"echo " $PROGNAME --version" }print_help() {print_revision $PROGNAME $REVISIONecho ""print_usageecho ""echo "Check Weblogic status"echo "" }#parse weblogic parameters parse_wls_para() { # echo $@while [ -n "$1" ]docase "$1" in--type)#typeTYPE="$2"shift;;--username)USER_NAME="$2"shift;;--password)PASS_WORD="$2"shift;;--domain)DOMAIN_NAME="$2"shift;;--server)SERVER_NAME="$2"shift;;--pool)POOL_NAME="$2"shift;;*)print_usageexit $STATE_UNKNOWN;;esacshiftdone#echo "TYPE:"$TYPE#echo "USER_NAME:"$USER_NAME#echo "PASS_WORD:"$PASS_WORD#echo "DOMAIN_NAME:"$DOMAIN_NAME#echo "SERVER_NAME:"$SERVER_NAME#echO "POOL_NAME:"$POOL_NAME}# check weblogic server information check_wls_server() {local URL="t3://${HOST_NAME}:${SERVER_PORT}"local SERVER_INFO="${DOMAIN_NAME}:${SERVER_NAME}"#echo "java weblogic.Admin -url ${URL} -username ${USER_NAME} -password ${PASS_WORD} get -pretty"#echo "-mbean "${DOMAIN_NAME}:Location=${SERVER_NAME},Name=${SERVER_NAME},Type=${SERVER_TYPE}"" tmpfile=`mktemp -t nagios.XXXXXX`#echo "tmpfile"$tmpfilejava weblogic.Admin -url ${URL} -username ${USER_NAME} -password ${PASS_WORD} get -pretty \-mbean "${DOMAIN_NAME}:Location=${SERVER_NAME},Name=${SERVER_NAME},Type=${SERVER_TYPE}" \>${tmpfile} 2>&1#echo "java weblogic.Admin -url ${URL} -username ${USER_NAME} -password ${PASS_WORD} get -pretty # -mbean "${DOMAIN_NAME}:Location=${SERVER_NAME},Name=${SERVER_NAME},Type=${SERVER_TYPE}" " local N=`cat ${tmpfile} | grep ^"-" | wc -l`#echo "N:"$N if [ $N -lt 1 ] then#error#echo "tmpfile"$tmpfile#cat ${tmpfile}ERR_INFO=`cat ${tmpfile} | awk '{ printf $0 }'`#echo "ERR_INFO:"$ERR_INFOecho "CRITICAL -

2.1將腳本上傳到Nagios軟件的libexec目錄下，并創建一個軟連接文件check_weblogic

使用的方法如下，
??? check_weblogic.sh -H host -p port -v '--type [jdbcpool|server] --username username --password password --domain domainname --server servername [--pool poolname]'

2.2編輯被監控主機的nrpe.cfg文件，增加如下內容，

#check weblogic [check_wls]
command[check_wls_mydomain_myserver]=sudo su - weblogic -c "/usr/local/nagios/libexec/check_weblogic -H localhost -p 6088 -v '--type server --username weblogic1 --password weblogic1 --domain hb_circfnl_dom --server AdminServer'" ommand[check_wls_jdbcpool_mypool]=sudo su - weblogic -c "/usr/local/nagios/libexec/check_weblogic -H localhost -p 6088 -v '--type jdbcpool --username weblogic1 --password weblogic1 --domain hb_circfnl_dom --server AdminServer --pool circDataSource'"

編輯 ?/etc/sudoers文件

? ? ? ?#vim ?/etc/sudoers

? ? ? ? ? ? ?nagios ALL=(ALL) NOPASSWD:/usr/local/nagios/libexec/check_tablespace.sh

同時得注釋掉一下行，表示不需要控制終端

? ? ? ? ? ??#Defaults ? ?requiretty

否則會出現：NRPE: Unable to read output 錯誤

#########################################################################################

PS：這一步我搞了很久，不是提示Unable to read output 錯誤，就是提示：“Please set JAVA_HOME!”，事后分析具體原因寫在這，免得走彎路，前面是在root環境下執行的，但是監控主機是和nagios用戶交流的，所以必須在nagios運行命令，而監控的命令調用的是weblogic用戶的的方法，所以的切得切換到weblogic用戶下執行命令。本來想用sudo命令，發現不行，還得結合su命令。入下圖所示：

2.3編輯監控主機的/usr/local/nagios/etc/objects/services.cfg文件（該文件是自己新增的）并且被監控的這臺主機也應該在host.cfg中定義好，增加如下內容

define service{use local-servicehost_name weblogicservice_description Weblogic Servercheck_command check_nrpe!check_wls_mydomain_myserver} define service{use local-servicehost_name weblogicservice_description Weblogic JDBCPoolcheck_command check_nrpe!check_wls_jdbcpool_mypool}

?3.檢查是否成功

3.1重啟被監控主機的nrpe

service xinetd restart

3.2重啟nagios服務

service nagios restart

3.3進入監控界面
