MainThread: Error, cannot match for network related data in "ip -s link" output on node 10.0.0.9 #14
Description
MainThread: Error, cannot match for network related data in "ip -s link" output on node 10.0.0.9
Steps to reproduce:
Run koet script on RHEL 7.x, SLES 12.x, Ubuntu Linux 18.04 or Ubuntu Linux 20.04
Expected results:
Success
Actual results:
Error, log file:
2023-12-22_15:46:52: MainThread: CMD: ssh -o ConnectTimeout=5 -o BatchMode=yes -o StrictHostKeyChecking=no -o LogLevel=error 10.0.0.9 ip -s link show eth0
2023-12-22_15:46:53: MainThread: Error, cannot match for network related data in "ip -s link" output on node 10.0.0.9
Root cause:
Different Linux distributions are based on different versions of the iproute program.
And different versions of iproute have a different output of the ip -s link show command. For example:
- RHEL 8.x, RHEL 9.x, Debian Linux 11.x, Ubuntu Linux 22.04, CentOS 9.x:
eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
RX: bytes packets errors dropped missed mcast
24853310197 16845711 0 0 0 0
TX: bytes packets errors dropped carrier collsns
39899639748 979955 0 0 0 0
- RHEL 7.x, SLES 12.x, Ubuntu Linux 18.04, Ubuntu Linux 20.04:
eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
RX: bytes packets errors dropped overrun mcast
31158468129 1501879 0 0 0 0
TX: bytes packets errors dropped carrier collsns
40617993630 1183331 0 0 0 0
And we can parse both options missed and overrun.
Thank you!
