Change value for Thresholds in email notifiation

[trungmv]

Hi all,

My system: CentOS 5.7
Cacti: 0.8.8
Spin: 0.8.8a
Thresholds: 0.4.9

I have receive notification from Thold of cacti that show the number is not interger Eg:

- With HDD used:
Message: ALERT: Machine1 - Used Space - C: Label: Seri [hdd_used] [hdd_used] went above threshold of 500000000 with 38639112192 (with 500000000 ~4,6Gb and 38639112192 ~ 36Gb )

- With Network:
Message: ALERT: Switch01 - Traffic - 1.1.1.1 - port1 [traffic_in] [traffic_in] went above threshold of 500000 with 585253.515 (with 500000 ~ 4Mb and 585253.515 ~4,6Mb )

How to change number from above to integer or rounded value? Eg: only display in email notification are: 4,6Gb or 36Gb with HDD used and 4Mb or 4,6Mb with network bandwidth ?
Where do i edit on cacti or what is the functions to do?
I very appreciate,
