|Title||lnx_if: Discover speed from /sys/class/net/INTERFACE/speed if ethtool missing|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Incompatible - Manual interaction might be required|
Previously if ethtool is missing then we do not get any information about interface speed. Now we collect speed information from /sys/class/net/INTERFACE/speed in this case.
You have to install the newest check_mk_agent.
The speed is remembered during discovery and if the speed changes the interface service report WARN. Thus you have to rediscover the related services in order to get the correct speed information.
