I have measurement called “weblog_requests”. I want to calculate availability %
the field resp_code is a number it stores http request code. the formula i am looking is

number of successful requests = requests with status code 2xx,3xx,4xx
number of failed requests = requests with status code 5xx
i need something like

number of successful requests * 100

(number of successful requests + number of failed requests)

how can i achieve that. In this case i have only one measurment

To get started you can run a count on a field.

SELECT count(“resp_bytes”)

This will allow you to see how many of a status code there are.You can do filtering.

Also consider using something like an aggregator so that you aren’t story the entire access log in InfluxDB if you only need counts
