Hi,

Most systems cannot handle a realtime query on like 2 seconds... I think our Cisco devices support 15seconds to get a accurate realtime.

Hi all,

I'm running community edition v0.13.10.4585 and polling a few C6500's and a Cisco Nexus 7k. I have a number of 10GE interfaces and 10GE etherchannel bundles. The 5 minute graphing appears to work fine, the numbers are accurate when I compare against another monitoring system in production. However, when I run a "real time" poll against an interface or port-channel, of any duration (2 secs to 60 secs), the numbers never crack much above 1gbps, and there are often negative numbers. This suggests 64-bit counters are not being used or being interpreted correctly, but I haven't looked at the code.

Has anyone else seen this? If so, did I mess something up with the install or is there something I can do?

Thanks,

I'm pretty sure I've heard this before, and without checking it I would agree the realtime grapher does not use 64 bit counters.

I'd say our polling logic which determines what counters to use (there are non-standard ones as well) should store this in the database, so we know which one to use for the realtime poller too...

If it bothers you enough, please file an issue for this on jira.observium.org
