What is the polling interval for the Monthly graph?

The polling interval for the Monthly graph in SonicWall Secure Mobile Access is indeed four hours. This means that the data presented in the Monthly graph is aggregated over a four-hour period, providing a comprehensive view of network activity and performance metrics throughout the month.

Setting a four-hour polling interval allows for a balance between the granularity of data and the efficiency of data collection. It provides enough detail to observe trends while ensuring that the system doesn't become overwhelmed with excessive data points. This is particularly important for analysis purposes where longer-term trends are more relevant, such as evaluating monthly usage patterns, identifying anomalies, or ensuring that resources are being utilized effectively over time.

In contrast, shorter polling intervals would yield too much data, making it difficult to discern meaningful trends, while longer intervals would result in a loss of important details in user activity and performance metrics. Therefore, the four-hour polling interval is designed to facilitate effective monitoring and analysis at a monthly scale.
