Check_MK Werk 4268: cisco_vpn_tunnel: Reporting zero traffic in case the tunnel is down

ID: 4268 Title: cisco_vpn_tunnel: Reporting zero traffic in case the tunnel is down Component: Checks & Agents Level: 1 Class: Bug Fix Version: 1.4.0i4 Previous versions of the check were not providing any performance data in case the tunnel was down. The graphs were showing flat lines for the time the tunnel was down which could lead to confusions because in fact there was no traffic at all.
