Microbursting Help Read Graphs

edit

Hi all,

hope anyone can help me I did an I/O capture using wireshark of the Bandwitdh of a mirrored port in a determined moment, but I have no idea how to read the data presented to me. Basically the switch has a 100Mbps port, and I wanted to know if I'm having microbursts (or something else) that is making the bandwidth rise above the limit of the port. Using the graphs below can anyone help please?
