Logging And Monitoring

Logging And Monitoring

Definition

• Logging and Monitoring are solutions for detecting issues and tracking the status of systems, respectively.

Logging

• Logging is a process to collect and store information about events.
• All logs are aggregated to some databases - central logging solution(e.g., AlgoExpert uses Stackdriver for a logging solution), providing useful detailed information about the activity of a system or application, errors, transactions, which is essential for analyzing and debugging.

Monitoring

• Monitoring is a tool for visualizing a system’s key metric.
• Key metrics depend on the system. For instance, one important key metric for AlgoExpert is Code Execution per Hour.

Alerting

• The process through which system administrators get notified when critical system issues occur.
• Alerting can be set up by defining specific thresholds on monitoring charts, past which alerts are sent to a communication channel like Slack.
