Hi,
I'm using cacti to monitor some servers running FBSD. I was using 7.2
with SCHED_4BSD. With this configuration : bsnmpd+bsnmp-ucd was
returning right values for the cores' load.
I recently updated the servers (via csup) to RELENG_8 and bsnmpd is
returning negative values for the cores' load. If I try something like
in a 4-core system :
snmpwalk -v 2c -c community server .1.3.6.1.2.1.25.3.3.1
what I get is :
.1.3.6.1.2.1.25.3.3.1.1.6 = OID: .0.0
.1.3.6.1.2.1.25.3.3.1.1.10 = OID: .0.0
.1.3.6.1.2.1.25.3.3.1.1.14 = OID: .0.0
.1.3.6.1.2.1.25.3.3.1.1.18 = OID: .0.0
.1.3.6.1.2.1.25.3.3.1.2.6 = INTEGER: -182
.1.3.6.1.2.1.25.3.3.1.2.10 = INTEGER: -182
.1.3.6.1.2.1.25.3.3.1.2.14 = INTEGER: -182
.1.3.6.1.2.1.25.3.3.1.2.18 = INTEGER: -182
I tried and old bsnmpd-ucd (0.2.1, works fine in a 7,2 system) with a
8.0 system. Same wrong results. And it seems bsnmpd in /usr/src/contrib
has not changed between 7.2 and 8.0.
Any ideas ? I'm not an expert, but with tcpdump I see different
results. Against an old 7.2 system, the field related to each core load
gives the right value. Instead, against and 8.0 system, those field show
(in hex) values like fd 4b. What I don't know is how bsdnmp-ucb retrives
those values and how it construct the udp response packet.
