Methods for managing insertion of metadata into a data stream to assist with analysis of network traffic and devices thereof

A non-transitory computer readable medium having stored thereon instructions for inserting metadata into a data stream comprising executable code which when executed by one or more processors, causes the processors to:

• generate a cloned network packet with a same header and payload as the a received network packet;
• generate metadata comprising state information for the received network packet, wherein the state information includes data associated with a session history of the received network packet;
• insert the generated metadata into a payload of the cloned network packet;
• send the received network packet to a destination device without including the generated metadata and without performing a network diagnostic operation on the received network packet;
• and
• perform the network diagnostic operation only on the cloned network packet.

A network traffic manager apparatus, comprising memory comprising programmed instructions stored in the memory and one or more processors configured to be capable of executing the programmed instructions stored in the memory to:

• generate a cloned network packet with a same header and payload as a received network packet;
• generate metadata comprising state information for the received network packet, wherein the state information includes data associated with a session history of the received network packet;
• insert the generated metadata into a payload of the cloned network packet;
• send the received network packet to a destination device without including the generated metadata and without performing a network diagnostic operation on the received network packet;
• and
• perform the network diagnostic operation only on the cloned network packet.

A network traffic management system, comprising one or more traffic management apparatuses, client devices, or server devices, the network traffic management system comprising memory comprising programmed instructions stored thereon and one or more processors configured to be capable of executing the stored programmed instructions to:

• generate a cloned network packet with a same header and payload as a received network packet;
• generate metadata comprising state information for the received network packet, wherein the state information includes data associated with a session history of the received network packet;
• insert the generated metadata into a payload of the cloned network packet;
• send the received network packet to a destination device without including the generated metadata and without performing a network diagnostic operation on the received network packet;
• and
• perform the network diagnostic operation only on the cloned network packet.
