Aside from increasing disk log quota, what is another method to manage logs on disk?

Specifying a global log roll policy is a valid method to manage logs on disk because it allows the FortiAnalyzer to automatically handle logs in a way that optimizes storage use and maintains performance. A log roll policy determines how logs are archived, deleted, or retained based on set criteria, such as age or size. This automated process enables administrators to ensure that the log storage does not exceed available disk space, while still retaining necessary logs for analysis, compliance, or audit purposes.

Implementing a log roll policy provides a systematic approach to managing logs without the need for constant manual intervention, which can be resource-intensive and prone to human error. This can lead to better log management, preventing issues related to disk space and ensuring that recent logs remain accessible for analysis.

In contrast, while deleting old logs manually can free up space, it is not as efficient or reliable as an automated roll policy. Reducing the log generation rate might limit valuable information that could be crucial for security analysis. Limiting the types of logs being recorded can lead to incomplete data for auditing or troubleshooting. Hence, a global log roll policy emerges as a robust solution in the context of managing logs effectively on disk.
