To ensure execution stability, this kernel module allows you to monitor status. After inserting the toa.ko kernel module, you can monitor the TOA working status in either of the following ways.
Run the following command to check the TOA metrics.
cat /proc/net/toa_stats
The monitoring metrics are described as follows:
| Metric | Description |
|---|---|
| syn_recv_sock_toa | Number of sockets that carry TOA information |
| syn_recv_sock_no_toa | Number of sockets that do not carry TOA information |
| getname_toa_ok | This count increases when you call getsockopt and get the source IP successfully or when you call accept to receive client requests. |
| getname_toa_mismatch | This count increases when you call getsockopt and get the source IP that does not match the required type. For example, a client connection contains an IPv4 source IP address whereas you get an IPv6 address, the count will increase. |
| getname_toa_empty | This count increases when the getsockopt function is called in a client file descriptor that does not contain TOA. |
| ip6_address_alloc | It allocates space to store the information when the TOA kernel gets the source IP and source port saved in the TCP data packet. |
| ip6_address_free | When the connection is released, TOA will release the memory previously used to save the source IP and source port. If all connections are closed, the total count of ip6_address_alloc for each CPU should be equal to the count of this metric. |
