ID: 10343 Title: lnx_if: Fixed flapping discovery of interfaces if output of ethtool is missing Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 Re-discoveries on Linux hosts which provide the {{lnx_if}} section may found new and vanished interfaces if the output of ethtool is missing. You have to perform a rediscovery on affected Linux hosts. Details: lnx_if section consists of three parts: {{ip address}}, {{/proc/net/dev}} and {{ethtool}}. {{ip address}} and {{ethtool}} may be missing. If the index of {{/proc/net/dev}} is available we use this one. Otherwise if the index of {{ethtool}} is available we use this one. Otherwise if the index of {{ip address}} is available we use this one. As a fallback we calculate the index synthetically.
