I'd like to plot a graph where the X-axis is the timeseries and the Y axis is a ratio of two certain field values (In my case, this is the "availability" metric which is defined as  
sum(response\_code = OK)/sum(response\_code = OK or response\_code = FAIL).

response\_code is the field which is available in the index.  
I am new to Kibana, but it appears that it does not support support custom metric computation.  
Any help?

This should be achievable in TSVB/Visual Builder, using the Math aggregation to calculate that ratio.

Could you please explain how do I sum the rows based on a filter (in my case, sum rows where the response code is OK)?
