nagios --自定义python插件cx_Oracle监控Oracle问题
本帖最后由 ontherd 于 2014-04-21 11:11 编辑Hi，
我在Nagios软件上调用自定义插件Python监控Oracle，报错Traceback (most recent call last):
File "/usr/local/nagios/libexec/check_oracle_jobs.py", line 11, in <module>
import cx_Oracle
ImportError: libclntsh.so.11.1: cannot open shared object file: No such file or directory但是我在nagios用户手动调用自定义插件却运行正常，$ ./check_oracle_jobs.py 10.68.2.21 orcl 123456 orcl 4
Critical - User:orcl job:362 is breken.|ora_broken_jobs=4;;;0我的系统环境变量配置，$ more /etc/profile
export ORACLE_HOME="/usr/local/instantclient_11_2"
export PATH=$PATH:$ORACLE_HOME
export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
export TNS_ADMIN=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME:$LD_LIBRARY_PATH
export SQLPATH=$ORACLE_HOME
alias sqlplus="$ORACLE_HOME/sqlplus"我的Nagios里配置文件command.cfg配置如下，
define command {
command_name check_ora_table
command_line $USER1$/check_oracle_table.py $HOSTADDRESS$ orcl 123456 orcl $ARG1$$ARG2$$ARG3$ $ARG4$
register 1
}下面是我写的python在监控Oracle数据库jobs的脚本，#! /usr/bin/env python

大家有没有遇到和我同样的问题，请各位大牛帮忙指点迷津。 nagios用户，在shell手动可以，自动是用cron？看上去是dll没找到，可能是环境变量的问题。

多谢大家关注，
自测出结果来了。
运行脚本包libclntsh.so.11.1这个动态链接库找不到。
动态连接库默认读取这个/etc/ld.so.conf文件，即默认/lib /usr/lib文件夹下的文件。
而我的Oracle简易客户端是安装在/usr/local/instantclient_11_2这个路径下。
所以我的操作步骤：
]# vi /etc/ld.so.conf 追加内容
/usr/local/instantclient_11_2
]# ldconfig
]# ldconfig -p | grep 'libclntsh.so.11.1' 测试是否能查询到，如果能查询到就OK了。
