. These are pulled into the network scripts usingsource
, so they are mainlybash
environment declarations of the form KEY=value. These are stored in thedata
property as a dictionary. Quotes surrounding the valueBecause this parser reads multiple files, the interfaces are stored as a list within the parser and need to be iterated through in order to find specific interfaces.

- class insights.parsers.sysconfig.NfsSysconfig(context)[source]
Bases:
SysconfigOptions
A parser for analyzing the
/etc/sysconfig/nfs
configuration file.Note
In some RHEL version, both the file
/etc/nfs.conf
and file/etc/sysconfig/nfs
exist, and take effect at the same time for NFS services on the host. And it’s possible that there are overlaps between the two configuration files. A combiner for the two configuration files was considered. Since the two files’ coverage are different, and it is quite complicate to enumerate all the configuration options and combine them properly, and also,/etc/sysconfig/nfs
is deprecated in lately RHEL releases. We deselect it as a consequence.Sample Input:
RPCNFSDARGS="--rdma=20049" #STATD_PORT=662
