For a short time after boot, macos sometimes mounts a filesystem of type "msdos" at the unique path /Volumes/firmwaresyncd.XXXXXX. Telegraf [inputs.disk] plug-in stores records to InfluxDB, with the unique mount path under "path" tag. The uniqueness of the path blows up the cardinality of the database. So exclude "msdos" filesystems from being monitored by telegraf. Additionally exclude "cd9660" filesystems that appear always as 100% full.
