Clarification: Logging Levels

SLB Ask: "How many levels of log defined? and what is the general rule? we see many INFO and few WARN logs"

Chris replied with "INFO, WARN, DEBUG". Where is "ERROR"? Are these the only levels within the log (check the code base).

Chris' statement is that the system's use of log levels is not consistent. We as DEV team members need a consistent statement on logging levels, their use, and an understanding of what we need to do to improve the code base wrt logging levels.

It starts with our producing a clear, concise statement & logging levels that we adhere to going forward & include this in our code review checklist. But we also need a card to retrofit the system's code to adhere to our practice. Is this a separate card or one where we fix the code as we move forward, with a touchpoint date of completing adherence?
