It may also be the only way because debuggers are not always available or applicable. This is usually the case for:

• multi-threaded applications
• and distributed applications

• Log20: Fully automated optimal placement of log printing statements under specified overhead threshold Zhao et al., SOSP’17 This paper presents Log20, a tool that determines a near optimal placement of log printing statements under the constraint of adding less than a specified amount of performance overhead. Log20 does this in an automated way without any human involvement. See also: Log20: Fully automated optimal placement of log printing statements under specified overhead threshold
