false positive NX-OS alert ?

[image: Inline image 1] Hello,
Is there any explanation - why this alert came up ?
From device sensors info now i see this information:
[image: Inline image 2]
The NX-OS stack (again) sent wrong condition information and alert generated by the "greater than 0" rule ?
Is there are the way to minimaze these false positives ?
Thank you.

I've never seen a false positive like that, how on earth has that device managed to confuse simple numerical tests?
I suspect it's injecting a strange character before or after the number or something.
There isn't any way for this to happen, really, unless the device is returning a strange invisible character before or after the number... Oo
Adam.

Sorry, i think its false negative;) maybe simple tuning of function - "if the first char is non number, then ignore" would protect from such cases
