[opennms-discuss] Configuration, rrd graphing, ssh problems

Hi,

I just installed OpenNMS this past weekend, and so far it's been great. 
Having played with it for a few days, I have some questions, mostly 
regarding configuration.  IP addresses have been cleansed.

If I am configuring more than 1 subnet, is the correct syntax in 
discovery-configuration.xml something like this:
        <include-range retries="2" timeout="3000">
                <begin>192.168.1.1</begin>
                <end>192.168.1.254</end>
        </include-range>

        <include-range retries="2" timeout="3000">
                <begin>192.168.254.1</begin>
                <end>192.168.254.254</end>
        </include-range>

Now, for every entry in discovery-configuration.xml, we need an identical 
entry in poller-configuration.xml if we want to poll it, correct?
Like:
    <package name="critical servers">
        <filter>IPADDR IPLIKE *.*.*.*≤/filter>
        <specific>0.0.0.0</specific>

        <include-range begin="192.168.1.1" end="192.168.1.254"/>
        <include-range begin="192.168.254.1" end="192.168.254.254"/>

That's all I need to discover and poll the default services, correct?

Re: [opennms-discuss] HTTP Status 500

Hi

About this bug, I would like to make a suggestion. Could the default 
graph type be the first existing graph in snmp-graph.properties. I don't 
know if this is easy to make that change since i don't code in java. 
Just a suggestion.

Seb.

[opennms-discuss] Microsoft DNS server

Hi,

I have a question we have a Microsoft DNS server in our network and Opennms "says" it is down but it isn't.

I found at the faq.opennms.org page a message about it and said to change the 'localhost' in de poller configuration file to something else like 'opennms.org', I changed it to an entry of an internal server (with is added correcty in the DNS and restarted opennms), but still......

What could be the problem and/or where can i find more about it like in the log files etc...

I hope anyone can help, thanks

Regards,

Raymond

Just to make sure, did you restart the OpenNMS services after making the change?

[opennms-discuss] unmanage service causes HTTP 500 error

Hi,

I am struggling with an HTTP 500 error when unmanage services from the GUI

javax.servlet.ServletException: Error writing the include url file /opt/OpenNMS//etc/include: /opt/OpenNMS/etc/include (Is a directory)

java.io.FileNotFoundException: /opt/OpenNMS/etc/include (Is a directory)

I had a look through all my xml config files, but no empty path is referenced there. Any ideas what might cause this ?

Regards + thx

Yes, that will work just fine.

Not exactly. You have to have a filter statement, but the other  
statements are optional. If you use the default of  
1.1.1.1-255.255.255.255 then the poller will only poll those things you  
discover, and since you pretty much controlled discovery in your  
discovery configuration file, it may be safe to leave it.

However, if you want to create multiple packages, you will need to  
specify more completely what IP addresses go with what packages.

The how-to is pretty complete on this:

Uh, there should be an snmp-graph.properties file and a  
response-graph.properties file.

You can

1) fix your network (grin)
2) increase the timeouts
3) add a "retry" parameter

OpenNMS acts like a user, so you want to set your timeouts as high as  
the slowest network performance is acceptable to your users. Note that  
OpenNMS will discover sympathetic causes - i.e. a slow DNS or no DNS  
entry for the OpenNMS server can cause SMTP in turn to be slow.

The categories page only reflects polled services. Are you polling this  
new subnet?

Hrm, this may be a bug. What version of OpenNMS are you using? When you  
say "hosed" are you seeing a lot of sshd processes?

This shouldn't be happening, but try

touch /opt/OpenNMS/etc/include

I know  reparenting is an issue for onms but was hoping someone could help
me out here. I need to reparent interfaces that got moved due to an outage.
Would someone mind sharing the best way to go about this?

Thanks for all replies
