I have created a log-based metric on Google Cloud against an AppEngine log. The metric scans for a specific URL and pulls out a field from that URL.
For example:
http://www.example.com/page.html?type=a
http://www.example.com/page.html?type=b
In Stackdriver, I can create the chart that shows the two metrics (types A and B) broken down by type at the same time.
What I am hoping to create is a chart that shows the ratio between types A and B. Is something like that possible? to perform any arithmetic operation on the results of a time interval?
