Thanks, Michael.  You didn't happen to but this in bugzilla, did you?

Tim,

Good to hear from you, could you provide an example with #1985 sort of how-to use this feature?

Thanks,

Re: [opennms-devel] Remote polling on same IP schemes

On Aug 8, 2007, at 4:12 PM, Ryan Kagin wrote:

Our problem is as follows (I apologize for those who have already heard this):
We have several sites, each with a router and switches behind the router which are unaccessable from the web. The switches all have the same IP scheme - 192.168.5.10, 192.168.5.15, etc. The problem is that when we have two remote pollers on two different sites polling the same service, the scheduler schedules all IPs that are the same, even if the node IDs are different.

A bug report has been filed on this issue, which is bug 1969.

Below is what I believe could be a start to patch this problem for us, but I am not sure how to proceed.

Unified diffs are a bit easier for us to visualize the changes. How's your progress on this issue? This should be a blocker bug at some point in the release cycle for 2.0.

No, my brain had stopped working; I'll put it in now. Thanks for the 
reminder.

Re: [opennms-devel] small patch to add regex filtering of eventparms

Sure. I’ve attached this to the bug as a comment as well.

This patch add to the configuration of events so that you can perform regular expression substitutions on the event parameters (trap varbinds) before the event is added to the database. For example, given an event type that maps SiteScope traps like this:

<event>
<mask>
  <maskelement>
   <mename>id</mename>
   <mevalue>.1.3.6.1.4.1.4875.3.1</mevalue>
  </maskelement>
  <maskelement>
   <mename>generic</mename>
   <mevalue>6</mevalue>
  </maskelement>
  <maskelement>
   <mename>specific</mename>
   <mevalue>9</mevalue>
  </maskelement>
</mask>
<uei>uei.opennms.org/vendor/DoubleClick/traps/siteScopeClear</uei>
<event-label>DCLK-SITESCOPE-MIB defined trap event: siteScopeClear</event-label>
<descr>
%parm[all]%
</descr>
<logmsg dest='logndisplay'><p>DoubleClick SiteScope Clear: %parm[#6]%.</p></logmsg>
<severity>Cleared</severity>
</event>

We see in the eventd log an event that looks like this:

Event {
   uuid = <not-set>
   uei   = uei.opennms.org/vendor/DoubleClick/traps/siteScopeClear
   src   = trapd
   iface = 192.168.2.43
   time = Wednesday, September 5, 2007 2:25:02 PM GMT
   parms {
     (.1.1, *** property not found (_goldProductCode))
     (.1.2, HOST)
     (.1.3, 1)
     (.1.4, EUDATA04)
     (.1.6, 137474)
     (.1.7, Sitescope::SNMPMonitor *** property not found (_goldMessage) attached=4356)
     (.1.8, *** property not found (_goldExpiration))
  }
}

We want to remove anything that looks like “*** property not found (_goldExpiration)” from the event parms before it gets written to the database. By adding to the event configuration for this event type, we can replace these strings.

<event>
<mask>
  <maskelement>
   <mename>id</mename>
   <mevalue>.1.3.6.1.4.1.4875.3.1</mevalue>
  </maskelement>
  <maskelement>
   <mename>generic</mename>
   <mevalue>6</mevalue>
  </maskelement>
  <maskelement>
   <mename>specific</mename>
   <mevalue>9</mevalue>
  </maskelement>
</mask>
<uei>uei.opennms.org/vendor/DoubleClick/traps/siteScopeClear</uei>
<event-label>DCLK-SITESCOPE-MIB defined trap event: siteScopeClear</event-label>
<descr>
%parm[all]%
</descr>
<logmsg dest='logndisplay'><p>DoubleClick SiteScope Clear: %parm[#6]%.</p></logmsg>
<severity>Cleared</severity>

<filters>
   <filter eventparm=".1.7" pattern="\*\*\* property not found \(\S+\)" replacement="" />
</filters>

</event>

We now see two additional lines in the DEBUG logs for eventd indicating that we are now filtering out these unwanted strings:

adding [.1.7|uei.opennms.org/vendor/DoubleClick/traps/siteScopeClear] to filter map
filtering .1.7 with \*\*\* property not found \(\S+\)

Thanks,
Tim

[opennms-devel] trunk rpm requires?

If you build rpms from the subversion trunk, what is it supposed to take 
to satisfy the require for "jdk >= 1.5".  I built and installed the 
jpackage  java-1.5.0-sun-1.5.0.12-1jpp.nosrc.rpm and the Sun 
jdk-1_5_0_12-linux-i586.bin on Centos5, but it doesn't provide a 'jdk'.
It provides jre, java, jave-sun, java-sdk and a bunch of other stuff, 
but no jdk.

Hm, are you sure the Sun JDK didn't work?  It worked for me...

As for the jpackage one, I've made a shunt RPM that can be used to act
as a stand-in for the Sun JDK.  I need to build it still, I've done so
for SuSE's java-1_5_0-sun-devel, which is similar to jpackage's.

I usually just grab the Linux RPM from Sun ...
