Usage reporting anomalys we are seeing.

[merman01]

Hi just wondering if people having any issues with reporting in their dashboard.

The first one is like this.

The 20 minute usage on the xxx appliance network from 09:00 AM to 09:20 AM IST on Sep 2 was 753.83 GB.

The thing is that if I totalled every piece of traffic on the network it doesnt reach 25% of that value.

We also see issues in the summary reports.

There are devices on the Top clients by usage are showing TB of usage when the actual usage is a tenth of that.

Also see traffic / usage assigned to devices that are not even on the network and when you click them the device isnt available.

A ticket is logged but not getting much feedback currently.

On which firmware is your mx?

Was thinking which version of what might help but forgot about the MX.
Firmware
Up to date
Current version: MX 18.211

18.211.3 reports a bug that sounds similar:

Due to an issue under investigation MX75, MX85, MX95, MX105, MX250, and MX450 appliances may report an erroneous spike in network traffic usage.

Just got reply from Support Team.

After further analysis and discussion internally, we are hitting a known unexpected behavior due to the MX. This is due to how the MX is syncing traffic counters across its CPU and dashboard.  Causing traffic to be counted multiple times when syncing which reflects in high usage being seen and email alerts being sent if configured. 

Currently our engineering team is working on a fix. Once it has been resolved it will be pushed in a firmware update.
