Hi there,
This might be a very basic question but I'm trying to get the ration of
error log messages / total error messages. Using grok_exporter I have the
metric type_counter which returns
ElementValue
type_counter{instance="localhost:9144",job="grok",log_type="AUTH"} 45
type_counter{instance="localhost:9144",job="grok",log_type="ERROR"} 55
type_counter{instance="localhost:9144",job="grok",log_type="IN"} 17603
type_counter{instance="localhost:9144",job="grok",log_type="NESTED"} 971
I simply then want (type_counter{log_type="ERROR"}) / (sum(type_counter)),
but this does not return a value, this is odd to me as both
type_counter{log_type="ERROR"} and sum(type_counter) return their expected
values and will divide by themselves or manually entered integers (such as
(18,000 / sum(type_counter)). I'm not sure why the division here is not
working, any ideas?
