Statistic | Description |
---|---|
Clients reset by switch on client side | The number of reset frames sent to the client by Alteon during server connection termination. This means that when Alteon could not connect to the real sever and the client’s retries exceeded the threshold due to delayed binding, Alteon sends a reset frame to the client to terminate the connection. |
Clients reset by switch on server side | The number of reset frames sent to the server by Alteon during server connection termination due to delayed binding. |
Connection Splicing to support HTTP/1.1 | The number of connection swapping between different real servers in supporting multiple HTTP/1.1 client requests. |
Invalid HTTP methods | The number of HTTP requests that contain invalid methods sent by the client. |
Aged delayed binding sessions | The number of aged delayed binding sessions caused by failed connection initialization between Alteon and the server. |
Half open connections | The number of outstanding TCP connections that are half opened. This increments when Alteon responds to TCP SYN packets and decrements upon receiving TCP SYN ACK packets from the requester. |
Switch retries | The number of Alteon retries to connect to the real server. |
Random early drops | The number of SYN frames dropped when the buffer is low. |
Requests exceeded 18200 bytes | The number of GET requests that exceeded 18200 bytes. |
Invalid 3-way handshakes | The number of dropped frames because of invalid three-way hand shakes. |
Exceeded max frame size | The number of Alteon-generated frames that exceeded the maximum allowed frame size. |
Out of order packet drops | The number of TCP out of order packets dropped. |
Out of order packets received | The number of TCP out of order packets received. |
Current SP memory units | The currently available SP memory units. |
Current SEQ buffer entries | The number of outstanding sequence buffers used. |
Highest SEQ buffer entries | The highest number of sequence buffers ever used. |
Current Data buffer use | The number of outstanding data buffers used. |
Highest Data buffer use | The highest number of data buffers ever used. |
Total Nonzero SEQ Alloc | The number of sequence buffers allocated. |
Total SEQ Buffer Allocs | The number of sequence buffers allocations. |
Total SEQ Frees | The number of sequence buffers that are freed. |
Total Data Buffer Allocs | The number of buffers allocated to store client request. |
Total Data Frees | The number of buffers freed. |
Alloc Fails - Seq buffers | The number of times the sequence buffer allocation failed. |
Alloc Fails - Ubufs | The number of times the URL data buffer allocation failed. |
Max sessions per bucket | The maximum number of items (sessions) allowed in the session table hash bucket chain. |
Max frames per session | The maximum number of frames to be buffered per session. |
Max bytes buffered (sess) | The maximum number of bytes to be buffered per session. |
