Opscenter 2.1 vs 1.3
Hi there,
I just upgraded to opscenter 2.1 (from 1.3). It appears that my writes
have tripled. Is this a change in the display/measuring of opscenter?
Best regards,

Robin,
RF shouldn't affect the numbers on that graph at all. The only
explanation for those differences that I can see is the increase in
the number of writes OpsCenter itself is doing. Do you see the same
jump in writes when viewing graphs just for your application's column
families?

Hi Nick,
I'm talking about the total writes/reads in the dashboard (left graph). It
exactly tripled during our update. I guess this is a change because of the
fact we also replicate with RF=3. Is that true?

Robin,
Are you talking about total writes to the cluster, writes to a
specific column family, or something else?
There has been some changes to OpsCenters metric collection/storage
system but nothing that should cause something like that. Also its
possible the number of writes to the OpsCenter keyspace itself would
have changed quite a bit between those versions, I'm assuming you
don't mean the column families in the OpsCenter keyspace though right?
