Holes in graphs

[WGPavell]

Sometimes graphs in cacti looks like this:

I think that is because cacti/rrd/something else can't handle big values but I can mistake.
In rrd file values looks like this:

So, how to fix this?

Change the logging to MEDIUM and look at the actual results coming back from the query.

the not-NaN values are near to 2^31 (maximum signed 32-bit integer), and no value is bigger than 2^31, so it seems you're using 32-bit counter for query. Use 64-bit snmp counters instead.
It also may be that you set an upper limit of 2^31 (2147483648) in the corresponding data sources, so that higher values are cut off.

And how to see them? I trying to search it in clog but I have no records about this graph.

I was create this graph with template "In/Out Bits (64-bit Counters)" so it cannot be 32-bit counter.

What Cacti version are you using?

Did you change the logging? if So, then all results should be in there. Depending on the Cacti version, you may have to search by data source ID.

I see some other DS but don't see DS for my graph.
