Hello,

 

Here in Brazil, we are concerned about the owamp powstream results. Maybe it was discussed in older threads, but it is still unclear to me.

We are running owamp postream between our measurement points, in a 10 packets/sec rate and summatization in 5 min.

The results that it shows in the measurements are having a strange behavior. A little packets are far away from most of them.

We are suspecting that this can be related to the host usage or something like that, but we are not sure to affirm this.

Could it be some I/O problem? Does anyone already notice something like this?

 

A sample of the measurements is below.
