Hi,
I have a 5 node cluster, and running ceph on them, and I have 18 ssd (enterprise ssd) osds. I created a testing pool on it, called "test1283". Zabbix reports [test1283]pool write bandwidth is 16.23 Tbytes (no way this high), and when I ran rados test on this pool (command like "rados -p test1283 bench 10 write --no-cleanup", I only get max bandwidth = 544 MB/s, no sure what to believe, and why zabbix reports such number? do I need to apply a multipler onto zabbix's reading?
thanks in advance for your help.
