esx and cacti 0.8.6k values problem

[polak92]

hi,

i just install a new cacti 0.8.6k to monitor the new esx infrastructure at work.

i ve found the last template for cacti 0.8.6j to get value per vm on this forum.

everything works great except the NIC traffic.
i have inexpectedly high value, even if it is in bits and not in bytes as i want, i have try to use CDEF but it doesn't give me good result too.

is anybody have the same issue or everything work great exept for me.
i ve try different version of cacti and the same result is given by the template.

as you can see i have 117.22G of traffic ?!?

OK

thanks for helping

Wow, the CDEFs are quite unusual

CDEF:cdefa=a,8192,* \
CDEF:cdefe=b,1024,* \
CDEF:cdeff=b,8192,* \

Traffic is measured in Bytes, so if you want to graph bits, multiply by 8. But those CDEFs multiply by 8192 and 1024, respectively. So please review the Fraph Template and make sure to associate the correct CDEFs. Then, visit the CDEFs (select Graph Management, then CDEFs) to verify that they are built correctly

Well. I am having the same problem this has been unsolved until now.
The problem happends mainly when you reboots a Virtual Machine, so those peaks that you can see are generated during the boot time.

Anyone has any update about it or solved the problem.
I thought to put a limitation of maximum amount of data like 100Mbit/s but it doesn't solve the problem. I was not able yet to understand what kind of data cacti gets from ESX during the boot to generate those outstanding values.

Anyone can help.

Thanks
