  • 0

I’d like to parse status.dat file for nagios3 and output as xml with a python script. The xml part is the easy one but how do I go about parsing the file? Use multi line regex? It’s possible the file will be large as many hosts and services are monitored, will loading the whole file in memory be wise?
I only need to extract services that have critical state and host they belong to.

Any help and pointing in the right direction will be highly appreciated.

LE Here’s how the file looks:

It can have any number of hosts and a host can have any number of services.
