Visualize uptime/downtime based on access_log data

I'm trying to figure out if I can report on lack of log entries in a time series, eg:

count number of minutes/buckets with 0 documents/entries in a specified time frame

and then

combine with total number of minutes/buckets in the set to get an approximated average service availability or downtime percentage.

I don't even know where to start on this one. Any thoughts?

You can use alerting to get notifications about log count going to zero.

Thanks, realtime notifications are often useful.

However, what I need is to generate a graph or even just a percentage for a given time frame, usually 1 month.

So, specifically, the percentage of minutes with non-zero (or more than some given number) log entries out of all the minutes in the month.
