How does this alert work?

indeni is kept up to date on immediate critical issues by scouring hundreds of different sources. In the case above, once the faulty driver was identified it was added to the list of issues to look for. indeni uses various outputs from ethtool (such as “ethtool -i”, “ethtool -c” and others) to determine that the problematic driver and feature is in use with the relevant NICs.
