The FortiView>Server Load Balance>Traffic Logs page shows server load-balancing traffic logs that the system has generated.
Selecting log categories
The logs are organized into 10 categories, as indicated by the radio buttons across the top of the page. They are:
- SLB Layer 4
- SLB HTTP
- SLB TCPS
- SLB RADIUS
- SLB SIP
- SLB RDP
- SLB DNS
- SLB RTSP
- SLB SMTP
- SLB DIANMETER
- SLB MySQL
You can view any of these types of logs by clicking the corresponding radio button, and the page will be populated with logs that are available in that category. If no logs are available in that category, the page will come up blank (with no logs).
Viewing SLB traffic log details
All logs are presented in a tabular format, with each row being a log entry. The log table shows some key information contained in the logs, which may vary slightly depending on the log category you select.
You can view details of a log by clicking the corresponding Preview button, as illustrated below.
Downloading SLB traffic logs
In the upper-right corner of the FortiView > Server Load Balance > Virtual Server page is a Download button. It enables you to download logs and save them in a .tar file. It comes in handy when you want to back up the logs for further analysis.
You can view the downloaded logs using a text-editing application. Below are some the most popular text editors you can use:
- WordPad (built-in in Microsoft Windows)
- NotePad ++
