Meta queries in terms of Arithmetic operation doesn't work in grafana 8.0.6 #136

BhoomikaAnghan commented 3 years ago

I am using Elasticsearch(oracle hist as named in image) data source and I want to do some Arithmetic operations (like sqrt or power(exponent)) on Metric field from Query A. I have installed a meta queries data source plugin and I am able to do basic arithmetic functions like (+,*,-,/) but it didn't work for getting sqrt or exponent. It is always returning 0 for sqrt. I have tried to use exponent(25^0.5) for getting sqrt but it doesn't work. Can anyone please suggest to me the right way to do it? I am not sure about this. Is it an issue with the plugin or I am doing something wrong? I could not get any information through the readme file for using this kind of operation from this plugin. expression

I am using an older version of Grafana, but was able to use more advanced Javascript math functions like square root (sqrt) and absolute value (abs) by appending Math.. For example, Math.sqrt(A['queryAlias']). Hope that helps.
