Hi Community ,
I want to trace the data transfer rates occurring between
osds while injecting data into ceph cluster. Can you please tell me
what ports should I monitor or keep track of?
Thanks !
Regards,
Hemant Surale.

OSDs start binding from port 6800 and counting up from there.
For example, a machine with 4 OSDs running:
root@atom0:~# netstat -nap|grep LISTEN|grep -E ^tcp|grep ceph-osd
tcp6 0 0 :::6800 :::*
LISTEN 24329/ceph-osd
tcp6 0 0 :::6801 :::*
LISTEN 24329/ceph-osd
tcp6 0 0 :::6802 :::*
LISTEN 24329/ceph-osd
tcp6 0 0 :::6803 :::*
LISTEN 24596/ceph-osd
tcp6 0 0 :::6804 :::*
LISTEN 24596/ceph-osd
tcp6 0 0 :::6805 :::*
LISTEN 24596/ceph-osd
tcp6 0 0 :::6806 :::*
LISTEN 25316/ceph-osd
tcp6 0 0 :::6807 :::*
LISTEN 25316/ceph-osd
tcp6 0 0 :::6808 :::*
LISTEN 25316/ceph-osd
tcp6 0 0 :::6809 :::*
LISTEN 25839/ceph-osd
tcp6 0 0 :::6810 :::*
LISTEN 25839/ceph-osd
tcp6 0 0 :::6811 :::*

Hi Wido , Community ,
if we use number =2
in cmd as follows
"ceph osd pool set <poolname> size <#no> "
does it means for perticular Object we have 2 replica Or total 2
copies in cluster?
Regards,
Hemant Surale.

That will set replication to "2". That means, every object stored in the
cluster will be stored twice.
It is NOT object + 2, no it's object * 2.

Sorry, I have to correct myself there.
Every object in that (RADOS) POOL is stored twice, not the cluster. This
is a pool specific setting, not cluster-wide.
