The DISPLAY-HINT is only in the MIB definition, not in the trap PDU.

This declaration is from the SNMPv2-TC (textual convention)  
definitions, not from RFC2271 (which defines the SNMP-FRAMEWORK-MIB).

The exception that you are quoting in your log output is in Notifd,  
which does not handle traps directly.  The handling of traps is done  
in Trapd, which turns them into events (handled by Eventd).  Notifd  
acts on events that match user-defined criteria.  This means that the  
exception is two levels of processing removed from the reception of  
the SNMP trap.

Can you capture one of these traps to a PCAP file using tcpdump?  Be  
sure to set the option "-s 0" so that the datagram does not get

No, that list spans all nodes.

[opennms-discuss] snmp trap generated from opennms

Hello,

It's about notification.
I am trying to send snmp traps from opennms to another server.
It works fine...
The problem is I can't find a way to send in the var bind, a parameter 
saying if the problem is resolved or not...
For example, when we use the mail, for the notification, opennms adds a 
RESOLVED at the beginning of the email subject, so we can know...

According to the doc (http://www.opennms.org/index.php/Event_substitutions),
there is no parameter we can specified... but is there any way ??? :)

This is the notification part, for the SNMP trap :

 <notification name="trap SNMP" status="on" writeable="yes">
        <uei xmlns="">uei.opennms.org/nodes/nodeLostService</uei>
        <description xmlns="">validate snmp trap</description>
        <rule xmlns="">CategoryName == "essai"</rule>
        <destinationPath xmlns="">SNMP-Notifier</destinationPath>
        <parameter name="trapVersion" value="v2c"/>
        <parameter name="trapTransport" value="UDP"/>
        <parameter name="trapHost" value="xxx.fr"/>
        <parameter name="trapPort" value="162"/>
        <parameter name="trapCommunity" value=""/>
        <parameter name="trapEnterprise" value=".1.3.6.1.4.1.5813"/>
        <parameter name="trapGeneric" value="6"/>
        <parameter name="trapVarbind" value="%nodelabel%"/>
</notification>

kind regards

Guillaume

Nop, the %uei% is the same no matter
if the trap is "the resolved one", the uei is also 
"uei.opennms.org/nodes/nodeLostService"

I'm not sure when it was added, but you can try to add

auto-discovery = false

as an attribute in your linkd-configuration.xml file and it won't  
discover anything. It is currently false by default in 1.5.90.

It occurs to me that you probably don't want auto-acknowledgements  
when using SNMP traps -- instead you would want to set auto-notify to  
"off" for the trap-generating destination path, and set up a  
notification definition for nodeRegainedService events.

Re: [opennms-discuss] SNMP Resource Graphs

I finally figure this out...

I am running into the 32bit rollover bug in net-snmp.

My ssCpuRawIdle counter is stuck at 2^32-1.  This makes it look like my
machines have no idle time....

As Jeff explained, the CPU Stats graph is using Idle time:  hence, 100%
usage.

The "CPU Usage" graph definition pulls in more data sources than the  
"CPU Statistics" one:

report 
.netsnmp 
.cpuUsage 
.columns 
= 
CpuRawInterrupt 
,CpuRawUser,CpuRawWait,CpuRawNice,CpuRawSystem,CpuRawKernel

report 
.netsnmp 
.cpuStats 
.columns 
= 
loadavg1 
,loadavg5,loadavg15,CpuRawUser,CpuRawSystem,CpuRawIdle,CpuRawNice

If you remove the loadavg* data sources from the cpuStats graph,  
you're left with CpuRawUser,CpuRawSystem,CpuRawIdle,CpuRawNice, which  
means that this graph does not include the CpuRawInterrupt,  
CpuRawWait, or CpuRawKernel.  Also, the cpuUsage graph does not  
include CpuRawIdle.

This sounds terribly inconsistent, but the reason these reports are  
defined the way they are is that there are significant differences in  
the stats that the Net-SNMP provides across different agent versions  
and different OS kernel versions.  There's a wiki article that goes  
into some detail on this subject:
http://www.opennms.org/index.php/Net-snmp_5.3_CPU_collections 
.

These graph definitions could probably stand updating.  Any volunteers?
