perfSONAR User Q&A and Other Discussion

["Niederberger, Ralph" <>]

Dear all,

Could anyone comment on the following two questions?


1.) Why does perfSONAR-UI provide info for "input errors" and "output drops" 
only?
       Does this mean the other way round, i.e. "output errors" and "input 
drops" do not exist?
       I would like to store values gathered from SNMP variables:
             IF-MIB::ifInErrors
             IF-MIB::ifOutErrors
             IF-MIB::ifInDiscards
             IF-MIB::ifOutDiscards

2.) Errors and Discards can occur when traffic comes in and goes out, I guess.
    So is the following XML definition for e.g. discarded packets right,
    if I want to store both kinds of values?

Is there something wrong with my suggestions, i.e. do I misinterpret 
something or misunderstand things?

Best regards

Ralph

Betreff: Re: [perfsonar-user] What means Utilization in SQL-MA

Dear Piotr,

thanks for your response. I have read the document you proposed.
Of course I know what utilization means, but the document does not
answer my question.

see comments inline below.

best regards

Ralph
