Hello all,
I am attempting to parse a Nagios status.dat file and am curious about
what the most efficient way to do this would be. I'm sure I could come
up with something but it would be very convoluted and I'm sure there is
a better way. Below is a sample of the file. The sections I am
interested in are the "hoststatus" sections. Any other section I want
to simply ignore. Within the hoststatus sections are a few lines I am
looking for: host_name=<whatever> and current_state=<whatever>, I'd
simply like to perform a task based on these "whatever"'s. For example,
output lines such as:
some_host:1
another_host:0
Where some_host and another_host are host_name's from the file, and 1
and 0 are current_state's for the corresponding host.
Any pointers or examples would be appreciated!
Here is a sample of the file:
