POS Interfaces on Cisco Router - Graph Incorrect

[smartinez1984]

We have a couple of Cisco 7204VXR routers connecting to OC3 circuits via POS interfaces. These interfaces are automatically set to max out at 155Mbps by the Cacti template.

Believe it or not, we are currently reaching points where one of these circuits reaches max capacity (we're gonna replace it with an upstream Gig soon) and the graphs get out of whack when this happens. The graph starts creeping up to the max and, when it gets there, the max drops to zero and then reports incorrectly.

I increased the value within the data source for this item entry but that hasn't helped. I don't see a place in the graph template to modify to increase this - can it be done? Or do I have to follow a different path?

Thanks!

Sounds like the counter is wrapping.

You can either try 64-bit counters or you can increase your polling interval for that Data Source. (FYI, you will need the 1 minute polling interval patch)

Yup - that was it, the counters were wrapping. I went to 64-bit counters and it seems to be working.

Thanks!
