Polling in real time failing

Can you help me, in mid day some times, some graphs in real time stop poling data, but its very random, and i want to know the cause  Disappointed

The rockests just star blinkin from nowhere.

  • I'm not sure this is the case but i came across something similar in the past where some network switches from other vendors than Cisco had the same issue, changing the real time polling to 3/5 seconds under Orion Advanced configuration fixed the issue.

    note that this change is affecting all real time polling
