hi eric:
thank you for reply so quickly,but I still have some question.
1.whether the mem_total mean : total RAM available in cluster,or not.
2.why eth0_XX have no record in my cluster,my hadoop cluster was running in my system.i have configure four machine for this cluster. why i only have eth0 and eth1, but i think i should have 4 ethernet cards . 3."sda_busy_pcnt Disk 0 Disk IO busy percentage per minute" you said,whether a or b,c means different disk from information you give ,if so, sda, sdb,sdc,sdd in my cluster whether they mean a disk in my each machine,but why sdb,sdd have on record in my cluster.
4.the load_1,load_5,load_15 represent what , why is no record in them.
5.today is jan 23th 2 pm ,but hicc only display the data to 8 am at the most,delayed 6 hours. but in introduction the delayed may be controlled in five minutes.what can i do for that?
