Hi Simon,

Observium is displaying values in Giga, so it's not wrong... Obviously it'll be a different number when using different units :-) (in effect it's RRDtool doing the value -> kilo/mega/gigavalue conversion, Observium has no clue you're polling bytes with custom OID).

Hi All

Im trying to find out if its possible to change the conversion rate being used in the CustomOID ?

When I SNMPGET a value from our storage system its returning a value and observium is then doing the conversion wrong…

This is the reply I received from there support team after hours of me trying to work out why observium was showing 416.5GB and they was showing 387.9GB


The command you are using shows result in bytes.
At the same time "vstorage stat" command shows result in Gibibites not Gigabytes. 

Just for reference:
1 Gibibyte = 230 Byte = 1,073,741,824 Byte
1 Gigabyte = 109 Byte = 1,000,000,000 Byte

#snmpget -v2c -cpublic 10.10.10.254 .1.3.6.1.4.1.8072.161.1.1.3.0
NET-SNMP-MIB::netSnmp.161.1.1.3.0 = Counter64: 416509057132
Here are output from your cluster:
vstorage -c hestor stat | head -n 10
connected to MDS#11
Cluster 'hestor': healthy
Space: [OK] allocatable 636.0GB (+2.28TB unlicensed) of 3.74TB, free 636.0GB of 1TB
MDS nodes: 7 of 7, epoch uptime: 2d 22h, cluster version: 126
CS nodes:  7 of 7 (7 avail, 0 inactive, 0 offline), storage version: 126
License: [Error] License not loaded, capacity limited to 1024Gb
Replication:  1 norm,  1 limit
Chunks: [OK] 1767 (100%) healthy,  0 (0%) standby,  0 (0%) degraded,  0 (0%) urgent,
             0 (0%) blocked,  0 (0%) pending,  0 (0%) offline,  0 (0%) replicating,
             0 (0%) overcommitted,  0 (0%) deleting,  0 (0%) void
FS:  387.9GB in 541 files, 541 inodes,  235 file maps,  1767 chunks,  3621 chunk replicas
416509057132/(1024*3) = 387.9 GB which is exactly the same as in "stats"
Just for reference: 1 Gibibyte = 230 Byte = 1,073,741,824 Byte 1 Gigabyte = 109 Byte = 1,000,000,000 Byte

Regards

Simon
