I'm running a couple of Ubuntu machines and a bunch of debian, the only
problem I've had with making net-snmp work is that it's not properly
detecting interface speed, so it's falling back to 10Mb on all of them.

#com2sec paranoid  default         public
com2sec readonly  default         hithere

Thats the only change I make to the stock snmpd.conf. Are you doing
anything more extensive?

Thanks,
Robert

Re: snmp ipaddrtable buggy packets

Hi Robert,
I'm actually making it even more simple than that...
here is my /etc/snmp/snmpd.conf file and /etc/default/snmp file... it's all very strange :S

rocommunity epoch 172.10.239.0/24

disk /
root <at> draco:/etc/snmp# cat /etc/default/snmpd
# This file controls the activity of snmpd and snmptrapd

# MIB directories. /usr/share/snmp/mibs is the default, but
# including it here avoids some strange problems.
export MIBDIRS=/usr/share/snmp/mibs

# snmpd control (yes means start daemon).
SNMPDRUN=yes

# snmpd options (use syslog, close stdin/out/err).
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid'
# 127.0.0.1'

# snmptrapd control (yes means start daemon). As of net-snmp version
# 5.0, master agentx support must be enabled in snmpd before snmptrapd
# can be run. See snmpd.conf(5) for how to do this.
TRAPDRUN=no

# snmptrapd options (use syslog).
TRAPDOPTS='-Lsd -p /var/run/snmptrapd.pid'

# create symlink on Debian legacy location to official RFC path
SNMPDCOMPAT=yes

How to deal with dynamic interfaces

Hi list,

while configuring data collection for linux-based devices with net-snmpd, I
noticed that dynamic interfaces like the ones created by pppd tend to go
down and reappear with a different interface number and a different IP
address (if no static IP adressing has been negotiated with the ISP) on
each connection re-establishment. This leads to "new" interfaces discovered
and the "old" ones being reported as down / outage.

Is there any easy way to deal with this? Even when I exclude the interfaces
from data collection and "unmanage" all the services they are rediscovered
on the "new" interface after the next reconnect.

Re: Cisco 6509s not being properly linked

Mine was blank too, so I started wondering how this got built and looked
for it.

Here are the SQL queries:

SELECT * FROM DATALINKINTERFACE WHERE NODEID = ? AND STATUS != 'D' AND
IFINDEX = ?
SELECT * FROM DATALINKINTERFACE WHERE NODEPARENTID = ? AND PARENTIFINDEX
= ? AND STATUS != 'D' 

So I checked my database and datalinkinterface is completely blank.  I'm
seeing the same thing on 1.7.  It appears that I just never configured
it.

Looking further, all this is handled by linkd.

The configuration for it looks like this:

       <vendor vendor_name="cisco" sysoidRootMask=".1.3.6.1.4.1.9"
                class-name="org.opennms.netmgt.linkd.snmp.CiscoVlanTable">
	    <!-- This is the oid for 6509 and should already be in your file -->
            <specific>1.283</specific>

Later in the file:

    <package name="LAN" use-ip-route-discovery="false">
                <filter>IPADDR != '0.0.0.0'</filter>
                <include-range begin="10.1.1.1" end="10.1.1.254"/>
    </package>
        <!-- here is a configuration valid on WAN where linkd try to get
             links using cisco discovery protolol first and then routers
ip route tables -->
         <!--
    <package name="WAN" use-bridge-discovery="false">
                <filter>IPADDR != '0.0.0.0'</filter>
                <include-range begin="10.1.1.1" end="10.1.1.254"/>
    </package>

(and a couple of other options)

My guess is that these are very resource intensive, but you may want to
figure out which one fits you and turn it on.  

Thanks,
Robert

Is there a way....

Hello all,

Does anyone have a quick and easy way to acknowledge all notifications? There is acknowledge all events, and alarms in the gui...but the notifications are page by page, 25 at a time.

Sometimes we get an event with notification that goes nuts and these are a pain to clear out.

So all help is apprciated.

Thanks

Re: Is there a way....

A bit of a hack, but, You can add this to the end of the url in the address bar - &limit=1000 or what ever is greater than the number of notifications you have and it will load them all on one page. Then just select all and ack.

RT Ticket integration -- Bad link to ticket

I have been playing with the RT integration but seem to have something wrong with my configuration. ONMS opens tickets fine, but it doesn't seem to use the returned ticket id.

In opennms.properties I have the following configured:

opennms.alarmTroubleTicketLinkTemplate = <a href="http://rt.cp.net/Ticket/Display.html?id=org.opennms:opennms-daemon:tgz:1.6.4">org.opennms:opennms-daemon:tgz:1.6.4</a>

When I query the DB, it has the RT ticket number in the alarms.tticketid field. When I have an alarm up in the GUI, the link by Ticket Id (upper left) says "org.opennms:opennms-daemon:tgz:1.6.4" and the url it links to is http://rt.cp.net/Ticket/Display.html?id=org.opennms:opennms-daemon:tgz:1.6.4

It seems to not be substituting in the tticketid stored in the DB -- the URL should be https://cp.net/Ticket/Display.html?id=394891

Is my configuration wrong, or is this a problem with ONMS? I'm running 1.6.4 build 12963

opennms.properties:

opennms.ticketer.plugin=org.opennms.netmgt.ticketer.rt.RtTicketerPlugin
opennms.alarmTroubleTicketEnabled = true
opennms.alarmTroubleTicketLinkTemplate = <a href="http://rt.cp.net/Ticket/Display.html?id=org.opennms:opennms-daemon:tgz:1.6.4">org.opennms:opennms-daemon:tgz:1.6.4</a>

rt.properties:

# The base URL of the RT ticketer

rt.baseURL=http://rt.cp.net

# Credentials used to login to RT - probably best not to use the default!

rt.username=opennms
rt.password=password

# The queue where the ticket will be raised

rt.queue=opennms

# The address of the requestor

rt.requestor=OpenNMS <at> cp.net

Thanks for the reminder, this is actually a maven filtering bug that I
need to look at.

Change "org.opennms:opennms-daemon:tgz:1.6.4" into ${id}

I'll take another look at fixing the build to do that properly.

It's Solaris so they won't be enabled by default. I had this problem I 
fixed it by finding the instructions in the wiki for tuning Postgres 
which has the details. I'm at home for the bank holiday now so I haven't 
access to my notes.
