How can i log db time , file time , and other for an api?

[codeimmortal]

I just want to know i am seeing every where only one line is mention to setup zipkins tracking .
var appzip = require('appmetrics-zipkin')({
host: 'localhost',
port: 9411,
serviceName:'backend',
sampleRate: 1.0
});
It is tracking api in my zipkins setup , but i dont see docs ,for example

Let say i have api which have datbase call , file read , file write , How can i trace how mach time which function has take in the particular api .
Does this module do that or i have to use other module to do so?

Any blog is there , I can not see any blog for that with respect to my use case ?
