What is the primary purpose of a "graph" in Zabbix?

The primary purpose of a "graph" in Zabbix is to visually represent trends in collected data over time. Graphs provide a graphical visualization of time series data, allowing users to quickly comprehend patterns, fluctuations, and overall performance metrics across different monitored entities. By illustrating the changes in monitored values, such as CPU load, network traffic, or disk usage, graphs enable users to identify anomalies, evaluate system behavior over specific periods, and make informed decisions based on historical data trends.

While storing historical data is essential for monitoring solutions, that function is not the primary role of a graph. Configuration of notifications pertains to alerting mechanisms rather than data visualization, and creating custom reports is more focused on data analysis rather than the dynamic visualization that a graph provides. In essence, a graph is a tool specifically designed for analyzing and understanding how data evolves over time, highlighting its significance in the monitoring and management process.
