 You can use [AzFileDiagnostics](https://github.com/Azure-Samples/azure-files-samples/tree/master/AzFileDiagnostics/Linux) to automate symptom detection and ensure that the Linux client has the correct prerequisites. It helps set up your environment to get optimal performance.
 
 ### Use the Always-On Diagnostics tool
 
-You can also use the Always-On Diagnostics tool (AOD) to collect logs on SMB and NFSv4 Linux clients. The daemon runs in the background as a system service and can be configured to detect anomalies in a variety of sources such as dmesg logs, debug data, and error and latency metrics. It can capture data from tcpdump, nfsstat, mountstsat, and other sources, along with the system's CPU and memory usage. AOD can be useful for collecting debug information on field issues that can be hard to reproduce.
