My graphs are showing that my filesystems have more free space than they really have. For example, I have a filesystem which has filled up, yet the graph and the stats on the OS page are saying that it is at 95%!
I have tracked it down to what appears to be that snmp is returning incorrect value for space available. It looks like it is calculating the available by subtracting the used from the size. However, if you add up the used and available values from df below, they don't actually add up to the size. I don't know if this is a problem with df on Linux. I am running zenoss-2.0.6. The client is: Red Hat Enterprise Linux AS release 4 (Nahant Update 2) Linux lnxbck1 2.6.9-22.ELsmp However, this is happening with another commercial Unix platform as well. Perhaps this is a problem with Net-SNMP. Code: $ snmpdf lnxbck1 /backup1 | egrep 'Desc|backup1' Description size (kB) Used Available Used% /backup1 206422036 196355324 10066712 95% $ ssh lnxbck1 df -kP /backup1 Filesystem 1024-blocks Used Available Capacity Mounted on /dev/sda1 206422036 196355324 0 100% /backup1 $ ------------------------ Peace Crew -------------------- m2f -------------------- Read this topic online here: http://community.zenoss.com/forums/viewtopic.php?p=11570#11570 -------------------- m2f -------------------- _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
