Python exports monitored service contacts and other information to an excel table based on the nagios configuration file

A few times ago, I had to count the services monitored by nagios to the table. I thought that if every change was required to maintain the table, there would inevitably be omissions or problems, so I observed the host of nagios. cfg, services. cfg and other configuration files write a script, including the processing of multiple hosts associated with the same service. The script also has limitations, that is, each host needs to be classified into a group, for example, if a Linux host is classified into a Linux Group and the actual environment is classified as such, files are generated during the script running process, but all files are small. The following are the corresponding module installation and script files, we recommend that you run the test on the testing machine before running it in the actual environment.

1. Install xlsxwriter

An excel operation module that allows you to operate on texts, numbers, formulas, and charts of multiple worksheets.

Pip installation method:

#pipinstallXlsxWriter

Source code installation method (download required)

#tar-zxvfXlsxWriter-master.tar.gz#cdXlsxWriter-master#pythonsetup.pyinstall

Ii. script file:
