Statistic | Description |
---|---|
Maximum sessions | The maximum number of simultaneous sessions supported. |
Current Sessions | The number of session bindings currently in use (the last four and 64 seconds). |
Terminated Sessions | The number of sessions removed from the session table because the server assigned to them failed, and graceful server failure was not enabled. |
Allocation Failures | Indicates instances where Alteon ran out of available sessions for a port. |
TCP Fragments | Indicates the number of TCP fragments encountered by Alteon. Layer 4 processing may not handle TCP fragments, depending on the configuration. |
UDP Datagrams | Indicates that the virtual server IP address and MAC are receiving UDP frames when UDP balancing is not turned on. |
Non TCP/IP Frames | Indicates the number of non-IP based frames received by the virtual server. |
Incorrect VIPs | Indicates the number of times Alteon received a Layer 4 request for a virtual server which was not configured. |
Incorrect Vports | A dropped frames counter that indicates that the virtual server has received frames for TCP/UDP services that have not been configured. Normally this indicates a mis-configuration on the virtual server or the client, but it also may be an indication of a potential security probing application like SATAN. |
No Available Real Server | A dropped frames counter that indicates that all real servers are either out of service or at their maxcon limit. |
Backup Server Activations | This indicates the number of times a real server failure has occurred and caused a backup server to be brought online. |
Overflow Server Activations | This indicates the number of times a real server has reached the maxcon limit and caused an overflow server to be brought online. |
Filtered (Denied) Frames | This indicates the number of frames that were dropped because of one of the following reasons: ![]() ![]() ![]() |
LAND attacks | This counter increases whenever a packet has the same source and destination IP addresses and ports. |
No TCP Control Bits | The number of packets that were dropped because the packet had no control bits set in the TCP header. |
Invalid reset packet drops | The number of packets that were dropped because the packet had an invalid reset flag set. |
Total IP fragment sessions | This represents the total number of fragment sessions Alteon has processed so far. |
Current IP fragment sessions | This represents the current number of fragment sessions. |
IP fragment discards | The number of fragmented packets that are discarded due to lack of resources. |
IP fragment table full | This counter indicates how many times session table is full. |
