Allow cumulative 'count' for Stackdriver logging events
Currently, with log-based metrics, there is no simple way to get 'How many times did this log appear within the past X days?' The only way this can be done is setting a custom time aggregator on a dashboard which is fed by a log-based metric. The time range cannot over-extend the first event, or it will show 0. This also doesn't integrate with a dashboard, as your custom time aggregator can't be modified afterwards.
Stackdriver should allow for a cumulative total (count) of 'How many times did this log entry appear based off of your search' and easily appear as a single total over a given time period.
Splunk, and many other log aggregation tools, allow for this functionality and it makes for more intuitive dashboard/results.

You can now use the Log Histogram and Field Explorer features in the new Logs Viewer to see a distribution of counts without the need to create a logs-based metrics.
