Cherry-pick of PR #12373 to 7.2 branch. Original message:
At the moment, when the System module starts it runs
sysinfo.Host()
to determine the host ID to use when calculating entity IDs. This call will not always succeed on systems that do not implement all the functionality we rely on. For example, we have had reports of Synology NAS systems not having/etc/machine-id
or/etc/lsb-release
files (for getting the IDs and OS information, respectively). When this call does not succeed, Auditbeat will fail to start if the System module is enabled (which it is by default).This PR allows the module to start without the host ID. It will log a warning, and documents will not contain any
entity_id
fields.
