Easiest way to filter notifications based on hostname and ifname

I have a bunch of edge switches on my network that I don't want to  
receive notifications for thresholds on for certain ports.

Each of the edge switches have the string "-es" in the hostname.  The  
client connections are all on FastEthernet interfaces on these devices.

I want to suppress notifications for anything with a hostname that  
includes the "-es" string and who's interface is FastEthernet.  I do  
not want to suppress notifications for anything with a hostname that  
includes "-es" and who's interface is GigabitEthernet.

I'm looking at building an event notification rule from the gui but  
I'm running up against a problem where the interface label from the  
event notification would be, for example label="Fa0/16", but I don't  
see anywhere in http://www.opennms.org/index.php/Filters that suggests  
I can use this interface label as part of the filter string for the  
rule.

Anyone know a way I may be able to do this?

Re: Easiest way to filter notifications based on hostname and ifname

You can use any of the database columns listed in database-schema.xml
(see the first paragraph of the Filters page on the wiki) in a filter
rule.  The hostname of the node is in there (nodeLabel, nodeSysName
might be useful as well), as well as the SNMP ifDescr (snmpIfDescr).

Some puzzles about monitoring JVM

Hello everyone.
Happy new Chinese ox year!
I am a newer here and I had some puzzles when I use Opennms to monitor my
servers.

First, I got that Java v1.5(and above) suppots the snmp management and we
can start snmp in command line when start JVM by using property
'-Dcom.sun.management.snmp.port=<port>' (of course, there is a proper file
of 'snmp.acl' as $JRE/lib/management/snmp.acl). Is this right? Is there any
method else to monitor JVM?

Second, what is the result if I start more than one application in the same
JVM by using property '-Dcom.sun.management.snmp.port=<port>'  each (surely,
the ports are differ from each other).

Thanks for any reply and best regards!

Jacky.Xu

Re: Some puzzles about monitoring JVM

Hi,

I've seen this question time and time again on this list, and so now I'm going to try and answer it as best I can
based on my own experience getting this to work in my environment. Take this all with a grain of salt: my
suggested configs are ones that I use. They may not be perfect but they do work. If there are improvements I
can make, please let me know.

First, you'll want to read up; there's tones of documentation on various methods of monitoring the JVM.
I'll try to summarize and save you some time, but it's up to you to read up and familiarize yourself with the
information I present here.

If you're using JDK1.5 update 5 or higher, I strongly recommend JMX. OpenNMS has a native JMX client to
collect metrics exposed by mbeans (both native and custom if you wish).

To enable JMX remote monitoring of a JVM, several steps must be performed:

1: Configure the target JVM for remote monitoring:

-Djava.rmi.server.hostname=<mgmt IP addr of host running JVM>
-Dcom.sun.management.jmxremote.port=10010
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

NB: these are not the most secure settings, but they simply work (without complication).

I use this feature of opennms to manage a bunch of JBoss clusters. There's a lot of data that can be gathered
this way, so make sure you configure what you want to collect -- ie: don't collect everything if you don't
need it -- unless you have some crazy storage for RRDs that doesn't choke under the strain of thousands of metrics.

For JBoss, you need two additional JVM startup parameters beyond those listed above:

Notification help - I want to know if ANY service is down, not all

We recently did a big upgrade which entailed me bringing down web services on
a server to do some maintenance.  I currently have a notification rule setup
as such:

(notifyCategory == 'ECF') & (isHTTP | isHTTPS | isECF_Live_Check)

During this entire time (about 8 hours) I never received a single alert that
the system was down.  However, as soon as I rebooted the system I was
alerted.  My only guess is that, since it appears to be OR that since the
system was pingable it assumed everything was okay.

I would like to know if ANY of these services went down.  I tried changing
the pipes (|) to ampersands (&) but that didn't have the expected outcome. 
How can I set this up to notify me if any particular service for this
notification category goes down?

Thanks

Hello,

 Has anyone set up a trouble ticket integration with BMC's Remedy and would be willing to provide some brief explanation?

Hi Russ,

I think that would probably need some coding (although someone might have done this already, in which case, ignore me ).

But I'm curious anyway. There seems to be some information out there on the Action Request API. Does your system present that interface to the world? The Java API looks pretty straightforward (though it seems to include some JNI code).

Cheers ... J
