What's means "accesses/s" in statistics?

Hi all.

Please teach me how to understand "Status/Statistics/filesystems" in V6.
What is means "accesses/s" in the graphs? Which units for measurement?
Is this "xxKByte per second"? Thanks.

Best regards,

Is this a value acquired from what?
snmp mib-2 xxxx?

RE: What's means "accesses/s" in statistics?

Maxtor 80GB SATA = 125-128 accesses/s
MLC SSD 30GB SATA = 3,000 accesses/s

Maybe this indicator show how fast storage. not serving.

close by myself. :D

Could we get an update from Open-e person on the meaning of accesses/s. I want to know how my system is performing.

What is considered high accesses/s for the filesystems statistics?

Thanks

Open-e please respond!!!! You have this as a "statistics" but what does it mean?

Thanks

Yes it is very different than previous stats which showed sector reads/writes.
Accesses could be the number of transfers per second, whether read or writes..

Sorry to resurrect this old thread, but I'm trying to figure out this answer to this question.
I thought of accesses being 512 byte sectors, but that doesn't seem to be the case. Can any one elaborate on this? If it's straight from iostat, then without the request size, it's hard to figure out. It would be far better to have the speed of the operation over the number of requests IF we cannot have both.

Don't need to say sorry we want to know this mechanism.
A lot of admin want to measuring of system performance from like this graph to using open-e more efficiency with limited resources. But now is relative values.

No takers on this guys? Low hanging fruit here begging to be picked ;)

In order to read the raw disk speed you need to convert the KB to MB/S, each sector is 512 bytes, and 512 bytes equal 0.5 KB.
