Nagios監控websphere插件安裝

Plugin for Nagios which allows monitoring the internals of WebSphere Application Server.

Start here: InitialConfiguration

Currently, the following items are currently possible to monitor:

• MonitorJvmHeapsize
• MonitorJdbcConnectionPools
• MonitorThreadPools
• MonitorLiveSessions

下載地址:http://code.google.com/p/nagios-was/downloads/detail?name=check_was-0.4-bin.tar.gz&can=2&q=

安裝:

1. [root@localhost etc]# cd /usr/local/src/tarbag/
2. [root@localhost tarbag]#tar zxvf check_was-0.4-bin.tar.gz -C /usr/local/nagios/libexec/check_was
3. [root@localhost tarbag]#cd /usr/local/nagios/libexec/check_was/

修改check_was程序:

1. [root@localhost check_was]# vi check_was
2. #!/bin/sh
3. PLUGIN_HOME=/usr/local/nagios/libexec/check_was
4. JAVA_HOME=/opt/IBM/WebSphere/AppServer/java \\這個java是websphere的java不是系統的java.
5. WAS_HOME=/opt/IBM/WebSphere/AppServer
6. $JAVA_HOME/bin/java -Dplugin.home="$PLUGIN_HOME" -cp $PLUGIN_HOME/check_was-0.4.jar:$WAS_HOME/runtimes/com.ibm.ws.admin.client_6.1.0.jar:$WAS_HOME/runtimes/com.ibm.ws.webservices.thinclient_6.1.0.jar:$WAS_HOME/plugins/com.ibm.ws.security.crypto_6.1.0.jar com.googlecode.nagioswas.Run $* 2> /dev/null

JAVA_HOME指定錯誤的話會報錯:

1. ERROR - ADMC0053E: 啟用 SOAP 連接器安全性時，系統無法創建連接到端口 8881 上的主機 localhost 的 SOAP 連接器。

修改check_was.servers

1. [root@localhost check_was]# vi check_was.servers
2. mtw.hostname=localhost
3. mtw.port=8881
4. mtw.username=yaoshi
5. mtw.password=www.yaoshi.com
6. mtw.securityenabled=true
7. mtw.truststore=/opt/IBM/WebSphere/AppServer/profiles/server01/etc/trust.p12
8. mtw.keystore=/opt/IBM/WebSphere/AppServer/profiles/server01/etc/key.p12
9. mtw.truststorepassword=WebAS \\這個是默認Key的密碼.
10. mtw.keystorepassword=WebAS
12. mtc.hostname=localhost
13. mtc.port=8882
14. mtc.username=yaoshi
15. mtc.password=www.yaoshi.com
16. mtc.securityenabled=true
17. mtc.truststore=/opt/IBM/WebSphere/AppServer/profiles/server02/etc/trust.p12
18. mtc.keystore=/opt/IBM/WebSphere/AppServer/profiles/server02/etc/key.p12
19. mtc.truststorepassword=WebAS
20. mtc.keystorepassword=WebAS

測試

1. [root@localhost check_was]# ./check_was -s connectionpool -w 80 -c 90 -p mtw
2. OK - connection pool size: Oracle JDBC Driver 1/10 (10.0%)|oraclejdbcdriver=10.0%;80;90;

修改websphere主機的nrpe.cfg

重啟nagios跟nrpe客戶端

check_was可以監控的內容:

MonitorLiveSessions:
check_was -s sessions -w 200 -c 400 -p <server name> -n <host name>
可以查看某一個JVM的全部sessions也可以指定某一個應用的session 加上-n 應用名

MonitorJvmHeapsize:
check_was -s heapsize -w 80 -c 90 -p <server name>

MonitorJdbcConnectionPools 數據庫連接池:
check_was -s connectionpool -w 80 -c 90 -p <server name> -n <connection pool name>

MonitorThreadPools : 線程:
check_was -s threadpool -w 80 -c 90 -p <server name> -n <thread pool name>
