Graph Doesn't Show Information

[tomasi]

Hi,

I'm trying to monitor some Ceragon 6GHz radios that have SNMP v1 enabled. I've created the items for Voltage, Temperature, Wireless Rx Power, with the correct OID (tested with snmpget) and created the graphs from these items.

When I do a snmpget:

c:\Tools>SnmpGet.exe -r:172.16.100.245 -c:public -o:1.3.6.1.4.1.2281.10.5.1.1.2.1
SnmpGet v1.01 - Copyright (C) 2009 SnmpSoft Company

OID=.1.3.6.1.4.1.2281.10.5.1.1.2.1
Type=Integer
Value=-52

c:\Tools>SnmpGet.exe -r:172.16.100.245 -c:public -o:1.3.6.1.4.1.2281.10.5.1.1.2.1

OID=.1.3.6.1.4.1.2281.10.5.1.1.2.1
Type=Integer
Value=-54

c:\Tools>

I receive the information correctly - at this time -52 and -54

The problem is: the graphs are empty, even with the correct information configured in Zabbix 3.2.1.

I already tried to change to v2c, v3, but without success till now.

Any suggestion/hint to try solve this?

shouldn't you use snmpv2 and add a communityname public?

Graphs now are ok



After a long night of tests, I discovered that 2 items was dropping all the SNMP queries: two items with OID related to QAM.

After disabling these two items, all the graphs suddenly started to show information about IDU and ODU voltage, Wireless Modulation, IDU and ODU temperature and wireless signal.

Now it's ok:
