Description

The current implementation of the LinuxProcFsStatistics.getNetStatStats() method assumes a particular ordering of stats within the /proc/net/netstat file on Linux systems and uses that assumption to parse the contents of the file when writing to the stats. However, different versions of Linux produce /proc/net/netstat files with the stats in different positions in the file, causing the incorrect stat values to be parsed and written to Geode stats, so a more robust approach is needed.
