Week 9 - The Importance of Logs

 Logs are very important to having a successful network configuration. Logs play a large role in providing crucial data to keep security and performance in check. So what exactly are logs? Logs are data streams collected over time to show insights and highlight different patterns and anomalies. Logs differ from metrics and events, as metrics and events generate data in real-time.

3 main types of logs are common:

• Access/Authentication 
• These are server logs of authentication attempts that are successful and unsuccessful
• System
• These are logs that have information about different drivers, system processes, and errors. For network logs specifically, they track the database systems 
• Application
• Application logs collect different event types. These event types will depend on how the software developer sets up the application and the desired data from the application.

So when it comes to cloud computing, why are logs so important? Well., one of the first reasons is to highlight system performance. By generating logs, there can be a historical record of what performance was like at one period of time versus another time. This can determine if system performance meets the requirements of the applications and systems. Optimizing the performance of applications over time produces greater results in productivity. Another benefit of having logs is for the security benefits. The way logs can provide security benefits is that they can offer audit trails, which provide periods to perform proper maintenance to maintain the security standards of the organization. Troubleshooting is a key component of maintenance and figuring out what issues occur and when they start occurring. With logs, records could indicate when certain systems started having problems along with additional information highlighting the issue. This is crucial with larger cloud setups where so much data is being dealt with at the same time. Last of all, is the monitoring capabilities of logs. Log monitoring can help network and cloud managers analyze and maintain their infrastructure by evaluating logs over time.

To conclude, logs are beneficial to maintaining performance, security, and troubleshooting of cloud environments. Cloud log monitoring houses a center for evaluating & analyzing data as well as processes of systems.
