I have had a look at the debugging site and it turns out the RRD
directory had somehow reverted ownership from user cacti to something
that didn't exist. All fixed and graphs are showing.

I also found for the bce0 network interface (FreeBSD Broadcom NIC 1)
that there were no data sourced defined for the graph. I also fixed
this and now I have full graphs for local host!


So thank you for that! :-)


The other machine that I have which is CentOS 6.2 x64 based running
net-snmp from the EPEL repos.... is still not working:

Output from snmpget:

snmpget -c 4622b8ba -v 2c 172.31.8.16 1.3.6.1.2.1.25.1.1.0
HOST-RESOURCES-MIB::hrSystemUptime.0 = Timeticks: (75939008) 8 days, 18:56:30.08


Uptime if I understand correctly is 8 days +.....


So why doesn't Cacti then see this?

The web-ui shows this:

SNMP Information
System:Linux uk-lon-nag-1.rjis.co.uk 2.6.32-220.13.1.el6.x86_64 #1 SMP Tue
Apr 17 23:56:34 BST 2012 x86_64
Uptime: 9411 (0 days, 0 hours, 1 minutes)
Hostname: uk-lon-nag-1.rjis.co.uk
Location: Monitoring Cluster
Contact: Master Kaya Saman


But under Console it shows as down:?

What information could I provide for this host to be useful?


The log shows that SNMP is querying the system:

May  9 11:59:08 uk-lon-nag-1 snmpd[12567]: Connection from UDP:
[172.31.8.17]:16996->[172.31.8.16]


No firewall is active on either system and nothing in the middle is blocking.


Regards,


Kaya
