ucd/net - Memory Usage won't work

[agismaniax]

I'm using cacti 0.8.5a on RH8 with net-snmp-5.0.1-6.

Why ucd/net - Memory Usage won't display any graph?
I try to snmpwalk for that OID and I found this:

Code: Select all

[root@email root]# snmpwalk -v1 -c public localhost 1.3.6.1.4.1.2021.4
UCD-SNMP-MIB::memIndex.0 = INTEGER: 0
UCD-SNMP-MIB::memErrorName.0 = STRING: swap
UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: -1
UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: -1
UCD-SNMP-MIB::memTotalReal.0 = INTEGER: -1
UCD-SNMP-MIB::memAvailReal.0 = INTEGER: -1
UCD-SNMP-MIB::memTotalFree.0 = INTEGER: -2
UCD-SNMP-MIB::memMinimumSwap.0 = INTEGER: 16000
UCD-SNMP-MIB::memShared.0 = INTEGER: -1
UCD-SNMP-MIB::memBuffer.0 = INTEGER: -1
UCD-SNMP-MIB::memCached.0 = INTEGER: -1
UCD-SNMP-MIB::memSwapError.0 = INTEGER: 1
UCD-SNMP-MIB::memSwapErrorMsg.0 = STRING: Running out of swap space (-1)

Is this bug on Net-SNMP Memory MIB or what?

From the faq

# I am using Redhat 8.0 and SNMP is not working.

Redhat 8.0 comes with a broken php-snmp package. Updating your 'php-snmp' and 'net-snmp' packages to their latest versions should fix this problem.
