On-device latency detection

A system comprising:

• at least one hardware processor;
• and
• at least one memory storing instructions that, when executed by the at least one hardware processor, cause the system to perform a process comprising:
• generating a first data record that includes a first timestamp associated with a first connection protocol packet, wherein the first timestamp indicates a time that the first connection protocol packet is transmitted from an application client to an application server on a remote system via a plurality of network sockets of that are associated with the application client;
• parsing subsequent packets communicated between the application client and the application server to identify, while the plurality of network sockets are open, one or more second connection protocol packets that are expected to follow the first connection protocol packet according to a connection protocol sequence;
• associating respective timestamps with the one or more second connection protocol packets in response to identifying the one or more second connection protocol packets via the parsing;
• determining a latency measurement for the application client based on the first timestamp included in the first data record and the respective timestamps associated with the one or more second connection protocol packets, the latency measurement describing a duration of the connection protocol sequence;
• and
• while the plurality of network sockets are closed, transmitting the latency measurement to the application client.

At least one non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor of a system, cause the system to:

• generate a first data record that includes a first timestamp associated with a first connection protocol packet, wherein the first timestamp indicates a time that the first connection protocol packet is transmitted from an application client to an application server on a remote system via a plurality of network sockets of that are associated with the application client;
• parse subsequent packets communicated between the application client and the application server to identify, while the plurality of network sockets are open, one or more second connection protocol packets that are expected to follow the first connection protocol packet according to a connection protocol sequence;
• associate respective timestamps with the one or more second connection protocol packets in response to identifying the one or more second connection protocol packets via the parsing;
• determine a latency measurement for the application client based on the first timestamp included in the first data record and the respective timestamps associated with the one or more second connection protocol packets, the latency measurement describing a duration of the connection protocol sequence;
• and
• while the plurality of network sockets are closed, transmit the latency measurement to the application client.
