Performance metadata for switches

The performance metadata is divided into the following categories:

• Key metadata
• I/O rates metadata
• Error rates metadata
• Port Protocol Errors metadata
• Link Errors metadata
• Miscellaneous metadata

The following key metadata is collected for switch performance:

• Data Rate (Receive, Sent, Total)
• Bandwidth (Overall, Receive, Send)
• Other (Total Port Error Rate)

The following I/O rate metadata is collected for switch performance:

• Frame Rate (Receive, Send, Total)

The following error rate metadata is collected for switch performance:

• Bad EOF CRC Error Rate
• CRC Errors
• Discarded Class 3 Frames
• Error Frames
• F_BSY Frames
• F-RJT Frames
• Long Frames
• Short Frames

The following port protocol error metadata is collected for switch performance:

• Class 3 Receive Timeout Frame Rate
• Class 3 Send Timeout Frame Rate
• Credit Recovery Link Reset Rate
• Discarded Frames
• Link Reset Received
• Link Reset Transmitted
• Port Congestion Index
• Zero Buffer Credit Percentage
• Zero Buffer Credit Rate

The following link error metadata is collected for switch performance:

• Encoding Disparity
• Invalid Link Transmission Rate
• Invalid Transmission Words
• Link Failures
• Primitive Sequence Protocol Errors
• Signal Loss
• Synch Loss

The following miscellaneous metadata is collected for switch performance:

• Frame Size (Overall, Receive, Send)
• Other (Link Quality Percentage)
