Re: To many SNMP outage identified on interface on Juniper MX80-PE

Hi Rupesh!

I got something similar once on a different router, it turned out that one of 
the tables had entries indexed with negative numbers (or numbers too high for 
a signed integer) and OpenNMS choked on that somewhere internally. Perhaps 
the Juniper has negatively-indexed virtual or management interfaces 
somewhere?

This was also a fairly random occurrence, frequency depending on how many 
times that index was already seen. In my case it was an Alcatel-Lucent/Nokia 
7750SR that has two internal services with negative SNMP indexes. The more 
often the services table was read (i.e. the more services I had configured), 
the more often I would get SNMP outages and gaps in the resource graphs after 
that point.

The workaround in my case was to throw away all data from those 
negatively-indexed services, which was easy because they were recognizable by 
their name.

This was already some time ago, though. This behavior might be changed in 
newer OpenNMS versions.

Kind regards,
 	 Marcel de Boer

To many SNMP outage identified on interface on Juniper MX80-PE

Hi all,
            I am having trouble with one of my Juniper Router, I keep getting SNMP outage identified on interface xx.xx.xx.xx with reason code: SNMP poll failed, addr=xx.xx.xx.xx oid=.1.3.6.1.2.1.1.2.0.  
             I am not able to get the complete resource graph. When I am using loopback IP as the snmp primary interface, I am having lot of breaks in recourse graph, but when I am using one of the interface of the router as SNMP primary interface I am having smooth recourse graph but eventually there is a gap in the graph for certain time frame. I am not sure what changes I need to do in configuration to overcome this issue.

syslogd ueiMatch Issue not returning the correct uei

OpenNMS Version 1.12.5 

 

I have setup a ueiMatch to process a syslog message and I can’t figure out why it’s not returning the correct uei.  It returns a default “this did not match anything” message, indeterminate.  I’ve tested the regular expressions with a parser/tester and the expressions work as expected outside of openNMS.  I have many working ueiMatches so I’m using the same basic format.  Can anyone provide guidance?  Here is the ueiMatch    

 

   <ueiMatch>

                <process-match expression="^SlaveStatus$" />

                <match type="regex" expression="^MySQLSlaveStatus: master\/slave up to date for ([\w][\w][\w][\d]-[\w][\w][\w]-[\d][\d])$" />

                <uei>uei.opennms.org/vendor/prodea/syslog/slavestatus/current</uei>

                        <parameter-assignment matching-group="1" parameter-name="server" />

        </ueiMatch>

        <ueiMatch>

                <process-match expression="^SlaveStatus$" />

                <match type="regex" expression="^MySQLSlaveStatus: Slave not Active for ([\w][\w][\w][\d]-[\w][\w][\w]-[\d][\d])!$" />

                <uei>uei.opennms.org/vendor/prodea/syslog/slavestatus/slavenotactive</uei>

                        <parameter-assignment matching-group="1" parameter-name="server" />

        </ueiMatch>

        <ueiMatch>

                <process-match expression="^SlaveStatus$" />

                <match type="regex" expression="^MySQLSlaveStatus: Replication delay for ([\w][\w][\w][\d]-[\w][\w][\w]-[\d][\d]) is ([\d]+)$" />

                <uei>uei.opennms.org/vendor/prodea/syslog/slavestatus/replicationdelay</uei>

                        <parameter-assignment matching-group="1" parameter-name="server" />

                        <parameter-assignment matching-group="2" parameter-name="seconds behind master" />

        </ueiMatch>

 

Here is the raw syslog message.

Deploying a Poller at a customer's site

Good Evening World,

 

I’ve had a strange request.  One of my clients wants me to do some SMNP monitoring for him.  I’ve already got a good install of ONMS 17 running for my core network and my colo.  It’s monitoring about 400 nodes (We’re an ISP). 

I’m curious if anyone has ever tried to allow traffic through an ASA to monitor a remote network.  Ideally, I would put a poller out at each of his locations and make my server talk to it.  We’re not this customer’s ISP so, I’d have to be passing traffic across the internet and back to an external IP on my ASA, then make a translate to pass it to my ONMS server. 

 

Is that even possible?  Has anyone tried it?

 

 

Thanks,

Need help with relative change threshold

I’m testing a relative change threshold.  I’m polling a juniper firewall. 

 

Here is the threshold.  I’ve set the multiplier value to a low number for testing and understanding.

 

        <threshold

            description="A burst of traffic has exceeded maximum change"

            type="relativeChange" ds-type="if" value="0.5" rearm="0.0"

            trigger="1" ds-label="ifin"

            triggeredUEI="uei.opennms.org/vendor/juniper/firewall/burstDetected"

            rearmedUEI=" "

            filterOperator="or" ds-name="ifInOctets"/>

        <threshold

 

Here is the threshold event.

 

Threshold exceeded for SNMP datasource ifOutOctets on interface 172.19.37.1, parms: ifLabel="reth2_0-0010dbff1002" ifIndex="582" label="reth2_0-0010dbff1002" ds="ifOutOctets" value="14771.84" instance="582" instanceLabel="reth2_0-0010dbff1002" resourceId="node[242].interfaceSnmp[reth2_0-0010dbff1002]" previousValue="88637.04" multiplier="0.5"

 

 

How is the change calculated to determine if this hits the threshold?  Is there a way to tell what the calculated change is?  I’m confused by the previousValue being larger than value.  If I change the multiplier to a larger number and look at snmp data, I’m expecting a threshold message but it never comes in.  I’m not a math expert so any help is appreciated.

Migrating rrd/jrb data to newts/cassandra

Hi all,

anyone out there already tried to migrate the collected opennms data from jrb/rrd files to
newts/Cassandra ?

It should be possible using the rest interface to newts
https://github.com/OpenNMS/newts/blob/master/rest/README.rst

or by directly creating Cassandra tables with the SSTablesWriter

and import them with the Cassandra bulk loader (probably much faster):
https://docs.datastax.com/en/cassandra/2.0/cassandra/tools/toolsBulkloader_t.html
http://www.datastax.com/dev/blog/bulk-loading

Or is there already a tool available for this purpose?

Thanks

node clean up

When a node goes offline for a certain period of time? Does opennms delete this automatically?

This looks like a bug with the Newts integration. I created an issue here:
    http://issues.opennms.org/browse/NMS-8103

It doesn't look like there's a workaround short of disabling the extension for the time being.

Newts is new in 17.0.0, so let us know if you run into any other issues. You can see the list of Newts related issues

PRIS and multiple Interfaces XLS

Hi

Looking at the documentation for PRIS in the XLS section it says

To add a node with multiple interfaces, add a subsequent row with the same node label (Node_). This row will
be added as a new interface based on the data from the IP_, MgmtType_, svc_ columns.

I was hoping to clarify before I run this that this means I do not need, nor should I repeat the foreignid for a
node when adding multiple interfaces?

Thanks
Patrick
