NSClient++ Help (#1) - network traffic from HP Network team (#748) - Message List

I'll use a different approach on this. Trying to use CheckWMI for this, and just check both teamed cards (we set them on failover anyway). So I want to get Received and Sent bytes from all HP cards.

What I got so far is:

./check_nrpe -H audiinsa0203 -c CheckWMI -a 'Query=Select Name,BytesReceivedPersec,BytesSentPersec from Win32_PerfFormattedData_Tcpip_NetworkInterface'  'columnSeparator= & '
BytesReceivedPersec=331 & BytesSentPersec=0 & Name=HP NC382i DP Multifunction Gigabit Server Adapter & BytesReceivedPersec=331 & BytesSentPersec=0 & Name=HP NC382i DP Multifunction Gigabit Server Adapter _2 & BytesReceivedPersec=0 & BytesSentPersec=0 & Name=HP NC382i DP Multifunction Gigabit Server Adapter _3 & BytesReceivedPersec=0 & BytesSentPersec=0 & Name=HP NC382i DP Multifunction Gigabit Server Adapter _4 & BytesReceivedPersec=0 & BytesSentPersec=0 & Name=isatap.in.audi.vwg & BytesReceivedPersec=0 & BytesSentPersec=0 & Name=isatap.{DA4AB6AF-8220-4D87-BEF9-46ED482A1932} & BytesReceivedPersec=0 & BytesSentPersec=0 & Name=isatap.{6FF81680-1C32-4AD4-A2C2-DE503DD30886} & BytesReceivedPersec=0 & BytesSentPersec=0 & Name=Reusable ISATAP Interface {FA319084-BFFD-4565-858D-EE755F45AAB1}

so here all those Windows Interfaces (isatap) are included. I need to filter for the HP cards:

./check_nrpe -H audiinsa0203 -c CheckWMI -a 'Query=Select Name,BytesReceivedPersec,BytesSentPersec from Win32_PerfFormattedData_Tcpip_NetworkInterface'  'columnSeparator= & ' +filter-string="HP NC382i DP Multifunction Gigabit Server Adapter"
BytesReceivedPersec=0 & BytesSentPersec=275 & Name=HP NC382i DP Multifunction Gigabit Server Adapter

this works so far, but I need to set the filter more like a regex, how would I do that? i.e.

$1 =~ /HP/
