Wrong SNMP statistic

[Aubrecht]

Hello,
I have problem with viewing service statistic.

Its standard SNMP service :

check_xi_service_snmp! -o 1.3.6.1.4.1.25053.1.1.12.1.1.1.3.1.2.1 -C public -P 2c!!!!!!! (its for monitoring no. of devices at Ruckus WIFI AP at 2,4Gh)

At realtime overview showing correct data ( SNMP OK - 29 ), but at graphs and exports data are strange:

Example of export:

'1487867100','8.2081597679e+05'
'1487867400','3.0488888889e-03'
'1487867700','7.3587106325e+06'
'1487868000','6.1370310460e+06'
'1487868300','8.1795266023e+06'
'1487868600','6.1370310445e+06'
(first column its timestamp its OK, but then have to be value 0-200 not 820815.97679)
See pistures

Where should be problem? How to export/view correct data?

In short, when the check_snmp command polls a counter, the application that creates and updates the graph, sees that is it a counter and processes the differences between the data.
That routine has rounding errors and only graphs the rounded data.
To fix it, you will have to follow this post and change the data received to a gauge and then the data will be plotted correctly.
Take a look at this post for more details and instructions.
