1 STORAGE MONITORING FINDINGS KEY FINDINGS FOR STORAGE MONITORING INDUSTRY FACTS 38 files Files that should be cached based on NFS response counts. This will improve network utilization and experience for users in branch offices. PCI, HIPAA, and Sarbanes-Oxley all require file audit access TechNet In Windows Server 2008, CHKDSK requires 6 hours to identify corrupt files in a system with 300m files TechNet 1.42K errors Storage errors can be investigated to identify corrupted files, access, and performance issues. 1 scheduled backup A scheduled backup job is causing zero windows (extreme latency) in NAS response and causing application errors. 1

2 The Storage Monitoring dashboard surfaces storage metrics for CIFS, iscsi, and NFS transactions. Storage performance is a crucial element for many applications, including database, virtualization, and VDI. The storage dashboards included in the project provide both the high-level overview and transaction-level details that storage teams need to rapidly identify, proactively fix, and avoid waste or unnecessary upgrades. Correlating storage activity the network and application level analysis. storage problems. Here you can see the most accessed files. By optimizing the way these are delivered, you can improve user experience and reduce network resource expenditure. 2

3 The Storage dashboard includes metrics that show the impact of the network on storage performance. The charts highlight metrics such as the 95 th percentile of storage network latency that the storage team should monitor closely. If they observe noticeable outliers, they can drill down to investigate possible causes, such as an oversubscribed switch, router, or firewall, or possible interface misconfigurations on the storage systems. 3

4 The Storage Monitoring dashboards include a dashboard that focuses on errors. Storage errors can now be monitored in real-time by the storage team, including details such as files involved. This view enables the storage team to proactively identify and fix issues before they cause downtime or application errors. 4

5 The storage error-focused dashboard includes details necessary for fast troubleshooting, including top error messages, files encountering errors, and users encountering errors. 5

6 The storage error-focused dashboard includes details necessary for fast troubleshooting, including top error messages, files encountering errors, and users encountering errors. 6

7 The Storage Monitoring dashboard includes an informative section that explains what error codes and messages mean. 7

8 The storage dashboard that focuses on file access highlights overview metrics that the storage team must monitor to ensure performance. They can easily see when access times are degrading and then drill down to discover why, for example. 8

9 Here you can see the most accessed files. By optimizing the way these are delivered, you can improve user experience and reduce network resource expenditure. 9

10 Locked files cannot be edited by other users. This view provides an easy way for storage administrators to detect locking issues that may be the reason for reported storage problems. 10

11 The storage dashboard that displays network metrics provides storage administrators and other team members how network latency impacts storage performance. This information is essential when looking for abnormal behavior, such as extremely large file transfers or frequent transfers of smaller files. 11

12 In the lower portion of the storage dashboard focused on networking, the metrics focus on retransmissions, timeouts, and zero windows. These metrics are gathered based on advanced TCP analysis that is only possible through ExtraHop s full-stream reassembly capabilities. 12
