Description:

All of us, the good developers, write logs in our code. Most of the times, logs are the only way for us to know what exactly has happened in our applications in a given period of time, which code paths were taken, which of them errored out. Some of us use the right logging levels diligently too. But, are we logging the right way?

  1. Can we find the logs that what we're looking for really quickly, when unexpected things happen?
  2. Are we able to slice and dice these logs based on the parameters/variables present in the logs?
  3. What about the same in micro-services world?

Yes (without hesitation) to these would be awesome and tell we're on right path. One may tend to think that the answers mostly depend upon the log management system they use(SaSS solutions like splunk or OSS solutions like ELK), but in reality, in vastly depends on "what kind of logs" we pump.

By the end of the talk, the audience would know what can be done to get a yes to all those questions, irrespective of the log management system they use (unless it is grep :P)
