Software system logging based on runtime analysis

A non-transitory computer-readable storage medium containing instructions, that when executed, control a computer system to be configured for:

• upon receiving a first function call for starting a logging session from an application being executed, starting the logging session for a log entry and reserving space in an in-memory non-persistent storage for the log entry, wherein the first function call includes a metadata parameter that identifies the logging session;
• upon receiving a second function call for writing to a log entry from the application being executed, writing information to the log entry in the space in the in-memory non-persistent storage during the logging session;
• upon receiving a third function call to end the logging session from the application being executed, the third function call including an indicator that is generated based on the executing of the application:
• ending the logging session for the log entry,
• obtaining a stored configuration for the application from a configuration storage including different configurations for a plurality of different applications or contexts, the stored configuration defining conditions for classifying log entries of the application, and
• comparing the indicator that is generated based on the executing of the application to a condition of the configuration, wherein the first function call, the second function call, and the third function call are included in software code of the application being executed and are executed by the application during runtime of the application to selectively start and end the logging session for the log entry;
• when the indicator meets the condition of the configuration:
• copying the log entry from the space in the in-memory non-persistent storage to a persistent storage space;
• and
• deleting the log entry from the space in the in-memory non-persistent storage at a time after performing the comparing.

An apparatus comprising:

• an in-memory non-persistent storage;
• one or more computer processors;
• and
• a non-transitory computer-readable storage medium comprising instructions, that when executed, control the one or more computer processors to be configured for:
• upon receiving a first function call for starting a logging session from an application being executed, starting the logging session for a log entry and reserving space in the in-memory non-persistent storage for the log entry, wherein the first function call includes a metadata parameter that identifies the logging session;
• upon receiving a second function call for writing to a log entry from the application being executed, writing information to the log entry in the space in the in-memory non-persistent storage during the logging session;
• upon receiving a third function call to end the logging session from the application being executed, the third function call including an indicator that is generated based on the executing of the application:
• ending the logging session for the log entry,
