Check_MK Werk 4187: check_mk_agent.linux: better performance for tcp connections query

ID: 4187 Title: check_mk_agent.linux: better performance for tcp connections query Component: Checks & agents Level: 1 Class: Bug fix Version: 1.4.0i4 The previously method to get information about tcp connections will slow down if the host is under heavy load. The new option to get these information will be more stable in this point. The legacy method (cat /proc/net/tcp) will still be used for older linux distributions, where ss may not be available.
