I don't think such a status exists for this scenario (that shouldn't happen), but you can search the exporter's .elg for ERROR or last output:
cat $EXPORTERDIR/targets/fw.domain.com/log/log_indexer.elg | grep -i "ERROR"
tail -fn 1000 $EXPORTERDIR/targets/fw.domain.com/log/log_indexer.elg
Please send them to me personally (assuming they weren't already overwritten).
Next time it happens, copy them as quickly as possible or simply run: SmartEventCollectLogs
One manual way to notice if this happens again:
tail -fn 1000 $EXPORTERDIR/targets/fw.domain.com/log/log_indexer.elg | grep "rate \[log\]"
# if you stop receiving this line consistently for more than 1 minute (stating the estimated approximate exporter rate), then something is wrong.
Also, Any-chance your SIEM went down? (though the log-exporter should reconnect automatically).
