Re: Flow Vision or Top Talker?

Hi Amit,

 

Do you have any Host performance tools like Ganglia? During the time/point there is congestion bottleneck on the NPIV port, the Host perofrmance graphic tool(Ganglia) would be able to suggest which one is the top talker.

 

1) During the congestion period, what errors are you getting in RAS logs?

2) Are you also seeing Latency bottleneck alerts?

3) If so, are there any C3 discards on the NPIV and ISL's as well?

4) How many LPAR's/VIO mapped to the NPIV port?
