篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了python根据nagios配置文件将监控的服务联系人等信息导出到excel表格相关的知识，希望对你有一定的参考价值。
前阵子，遇到需要把nagios监控的服务统计到表格的需求，想着如果每一次改动，都要去维护表格的话，难免会有疏漏或者问题，于是观察了nagios的host.cfg,services.cfg等配置文件写了一个脚本，包含对多个主机关联到同一个服务的处理等，脚本也有局限性，就是需要把每个主机，都归类到某个组，比如Linux主机归类到Linux组，实际环境，一般也是有这样做归类的，脚本运行过程中会有文件产生，但都很小，以下是相应模块安装和脚本文件，建议在测试机上面跑完再到实际环境跑。
一，安装xlsxwriter
一个excel操作模块，可以操作多个工作表的文字、数字、公式、图表等。
pip安装方法：
#pip install XlsxWriter
源码安装方法（需下载）
#tar -zxvf XlsxWriter-master.tar.gz
#cd XlsxWriter-master
#python setup.py install
二，脚本文件：
import xlsxwriter
import sys
reload(sys)
sys.setdefaultencoding(‘utf8‘)
#注意路径
os.system("cat /usr/local/nagios/etc/hosts.cfg | grep -E ‘host_name|address|hostgroups‘ | sed s/[[:space:]]// | awk ‘{print $1,$2,$3}‘ | sed -e ‘s/[[:space:]]$//g‘ > /root/autocount/hostip")
#####################处理一行多个host_name情况########################
os.system("cat /usr/local/nagios/etc/services.cfg | grep -E ‘host_name|service_description|contacts‘|sed s/[[:space:]]// | awk ‘{print $1,$2,$3,$4,$5,$6}‘ | sed -e ‘s/[[:space:]]*$//g‘ | sed -e ‘s/,[[:space:]]/,/g‘ > /root/autocount/serviceip2")
#含有完整行的文件，及host_name都有的
os.system("cat /usr/local/nagios/etc/services.cfg | grep ‘host_name‘ | sed s/[[:space:]]// | awk ‘{print $2,$3,$4,$5,$6}‘ | sed s/[[:space:]]//g | awk ‘/,/{print $0}‘ > /root/autocount/serviceip1")
os.system("sort -u /root/autocount/serviceip1 > /root/autocount/serviceip3")
#去除重复行
with open("/root/autocount/serviceip3") as f3:
#a中保存有一行多个host_name的主机
a=f3.readlines()

#b中的某一行含有一行多主机中的一个主机
print k[j]
if i in m :
b.insert(len(b),‘host_name ‘+k[j]+‘\n‘)
l=0
#插入到最后，然后进入下一次的for m in b，即往后面继续for了，就到下面的那个service_description,设置l是把最近的service_description同contacts加入到b的后面，而不是所有。
if ‘service_description‘ in m and l <= 2:
print m
#此时的len(b)是加入了一个host_name之后的，所以会继续往后insert
b.insert(len(b),m)
