Real Time Graph have Gaps

[dotangina]

Can anybody help me I'm seeing GAP on real time graphs. Thank you.

The gap here is appearing because Cacti believes there is no data. Look at the current value. Zero = no graph.

But it is happening on all graphs that I'm trying to poll. Physical Interfaces as well as sub interfaces.

The issue is that your snmp agent is caching values and not providing realtime values at the realtime interval you are specifying. On some older equipment, the network interface statistics are only reported to the snmp agent every 15 seconds. If you monitor with a 15 second realtime interval, the gaps will likely go away. Talk to your hardware provider about how to get more realtime statistics from the agent.
