Re: Not Polling data for Linux Node using Perl Script

Thanks for your reply, But my problem is only Linux node not polling the data
while configure the Linux node IP using Perl script. Please let me know if
there is any changes in the xml file or specific configuration that i need
to do for the linux node ip monitoring in Opennms?

Thanks in Advance,
Vinoth

SMS Notification (pulling a name from the users.xml file)

Hi oNMSer's



"I would like it if my script could parse the users.xml file and extract the users name from the xml based on the mobile number, to populate the answered by field in the notifications table, but I'm afraid I not yet up to the task. I was messing around with Java and Xerces. Does anyone have an idea for this?"

well its not java...

#!/bin/bash

funcRetrieveBillingName ()
{

        billFullName=`grep -B 10 $billNumber /etc/opennms/users.xml | grep full-name | awk '{ print $2,$3 }' | cut -b 10-40 | sed  's/<\/full-name>//g' | sed -e 's/\t//g' | sed -e 's/\s\s+//g'`
        if [[ $billFullName == "" ]]; then
                echo "Number does not exist in the ONMS Directory"
        else
                echo $billFullName
        fi

}

funcRetrieveBillingName

Its nasty, and if the format of the file changes slightly it will break, but hey it works :D 

Cheers,
Bruce

Re: httpDataCollection / fetching multiple results

Yeah, I could absolutely return an XML formatted result.  If I did that, what would I need to do from there?

Subject: [opennms-discuss] httpDataCollection / fetching multiple results

I have an app that returns multiple result sets in a single GET like so via a web interface: 

jmsWorker.analyticsScoreWorker.avgQueueTimeMs 410507.0 412913.0 411083.0
lbsClient.tyntecSyncClient.avgProcessTimeMs 146.0 157.0 155.0
lbsClient.tyntecSyncClient.processCount 1329.0 1251.0 1253.0
locationModel.synchronousLocationModel.avgRunTimeMs 524.0 551.0 563.0
locationModel.synchronousLocationModel.runCount 1972.0 1869.0 1843.0
processor.analyticsScoreProcessor.avgProcessTimeMs 613.0 644.0 654.0
processor.analyticsScoreProcessor.processCount 1972.0 1871.0 1841.0
processor.defaultSyncLocationProcessor.Vodafone.avgProcessTimeMs 1030.0 1034.0 1034.0
processor.defaultSyncLocationProcessor.Vodafone.processCount 363.0 357.0 365.0

I'm trying to figure out a way that I can use the httpDataCollector to fetch these results and insert them into a JRobin database, where each line represents a single JRB database with three datasources, like so:

jmsWorker.analyticsScoreWorker.avgQueueTimeMs
   --> worker1
      --> 410507.0
   --> worker2
      --> 412913.0
   --> worker3
      ---> 411083.0

and so on...

(representing the data entered into a single JRB database).

I know I can create each JRB database by hand (JRobin API), populate them with datasources, assign them to a node for display, and even shove the data in.   I can do all of this outside of OpenNMS itself.  Why would I want to do this?  Because this data is being fetched from a database and OpenNMS does not currently have a SQLCollector and these statistics are not available via JMX (at least, not as Attributes).

So, I can do all of this by hand, BUT I also want to be able to monitor these results via thresholds and as far as I can tell, if a ONMS data collector is not doing the collecting, I can't do a threshold on it.  So my idea was to use the httpDataCollector to collect the data so that I could threshold on it.

It looks like though that the httpDataCollector is designed to only operate with one result set (i.e., one JRB destination with 1 or more datasources in it).  I need a way to operate on many result sets at one time, parsing line by line.

Is this even possible with httpDataCollector?  Is there any way at all to do it with ONMS or am I trying to fit a square peg into a round hole?

Thanks-
Jay

Re: httpDataCollection / fetching multiple results

I’ve got an open bug (NMS-4516) which adds an XmlCollector to OpenNMS.

 

If you don’t have a problem building opennms from source, you can apply the patch to a checkout of the git branch opennms/1.10.

Re: httpDataCollection / fetching multiple results

Thanks Ron, that looks like it will work for me.  I've already got a copy of the source from git, so I'll apply your patch, rebuild, and give it a try.

Re: httpDataCollection / fetching multiple results

I don't suppose you might have some raw docs or something on constructing the xml-datacollection-config and what the source XML should look like?  I'm trying to figure out what the "expression" attribute in the mibobj element does.  Based on the file you provide, I am guessing that an entry like this:


<mibobj name="sizeVirtual" alias="sizeVirtual" type="counter" expression="process/ <at> sizeVirtual" />

makes a call to some sort of control that returns a value.  I'm guessing that you end up with a RRD file ordered by "group name" and then multiple archives in that file ordered by mibobj.

Right now, I'm just trying to figure out how to structure the XML result so that it can be consumed like:

<metric>
   <archive>
    <archive>
   <archive>
<metric>
   <archive>
   <archive>
   <archive

... and so on, where <metric> is a specific instance of an RRD and the data consumed from the XML output is ordered by <archive> on a per <metric> basis (if that makes sense).

Re: httpDataCollection / fetching multiple results

The easiest way I guess is to have you look at the files used by the unit tests. XmlCollector_UnitTest_127.0.0.1.txt would be the file fetched containing the data. There are two unit test datacollection config files (xml-datacollection-config.xml & xml-datacollection-persist-test-config.xml) and also an example xml-datacollection-config.xml in opennms-base-assembly. (hmm, just noticed a typo in that last file.)

 

Here’s a quick example of grabbing data from a file: (capsd-configuration.xml)

 

<group name=”capsd-configuration” node-expression=”/capsd-configuration/protocol-plugin” key-expression=”attribute::protocol” resourceType=”capsd-protocol-plugin”>

  <mibobj name=”timeout” type=”gauge” expression=”property[ <at> key=’timeout’]/ <at> value” />

  <mibobj name=”retry” type=”gauge” expression=”property[ <at> key=’retry’]/ <at> value” />

</group>

 

This would create two files under ${opennms.home}/share/rrd/snmp/${node}/capsd-protocol-plugin/${protocol}/, timeout.jrb and retry.jrb.

 

Not a good real world example, but it should give you an idea from looking at capsd-configuration.xml.

I don't suppose you might have some raw docs or something on constructing the xml-datacollection-config and what the source XML should look like?  I'm trying to figure out what the "expression" attribute in the mibobj element does.  Based on the file you provide, I am guessing that an entry like this:

 

<mibobj name="sizeVirtual" alias="sizeVirtual" type="counter" expression="process/ <at> sizeVirtual" />

 

makes a call to some sort of control that returns a value.  I'm guessing that you end up with a RRD file ordered by "group name" and then multiple archives in that file ordered by mibobj.

 

Right now, I'm just trying to figure out how to structure the XML result so that it can be consumed like:

 

<metric>

   <archive>

    <archive>

   <archive>

<metric>

   <archive>

   <archive>

   <archive

 

... and so on, where <metric> is a specific instance of an RRD and the data consumed from the XML output is ordered by <archive> on a per <metric> basis (if that makes sense).

Thanks Ron, that looks like it will work for me.  I've already got a copy of the source from git, so I'll apply your patch, rebuild, and give it a try.

I’ve got an open bug (NMS-4516) which adds an XmlCollector to OpenNMS.

 

If you don’t have a problem building opennms from source, you can apply the patch to a checkout of the git branch opennms/1.10.

Yeah, I could absolutely return an XML formatted result.  If I did that, what would I need to do from there?

The HttpCollector does not support indexed data collection. How much control over the app do you have? Can you update the format of the data that it returns so instead of text, maybe in an xml format?

Subject: [opennms-discuss] httpDataCollection / fetching multiple results

I have an app that returns multiple result sets in a single GET like so via a web interface: 

 

jmsWorker.analyticsScoreWorker.avgQueueTimeMs 410507.0 412913.0 411083.0

lbsClient.tyntecSyncClient.avgProcessTimeMs 146.0 157.0 155.0

lbsClient.tyntecSyncClient.processCount 1329.0 1251.0 1253.0

locationModel.synchronousLocationModel.avgRunTimeMs 524.0 551.0 563.0

locationModel.synchronousLocationModel.runCount 1972.0 1869.0 1843.0

processor.analyticsScoreProcessor.avgProcessTimeMs 613.0 644.0 654.0

processor.analyticsScoreProcessor.processCount 1972.0 1871.0 1841.0

processor.defaultSyncLocationProcessor.Vodafone.avgProcessTimeMs 1030.0 1034.0 1034.0

processor.defaultSyncLocationProcessor.Vodafone.processCount 363.0 357.0 365.0

 

I'm trying to figure out a way that I can use the httpDataCollector to fetch these results and insert them into a JRobin database, where each line represents a single JRB database with three datasources, like so:

 

jmsWorker.analyticsScoreWorker.avgQueueTimeMs

   --> worker1

      --> 410507.0

   --> worker2

      --> 412913.0

   --> worker3

      ---> 411083.0

 

and so on...

 

(representing the data entered into a single JRB database).

 

I know I can create each JRB database by hand (JRobin API), populate them with datasources, assign them to a node for display, and even shove the data in.   I can do all of this outside of OpenNMS itself.  Why would I want to do this?  Because this data is being fetched from a database and OpenNMS does not currently have a SQLCollector and these statistics are not available via JMX (at least, not as Attributes).

 

So, I can do all of this by hand, BUT I also want to be able to monitor these results via thresholds and as far as I can tell, if a ONMS data collector is not doing the collecting, I can't do a threshold on it.  So my idea was to use the httpDataCollector to collect the data so that I could threshold on it.

 

It looks like though that the httpDataCollector is designed to only operate with one result set (i.e., one JRB destination with 1 or more datasources in it).  I need a way to operate on many result sets at one time, parsing line by line.

 

Is this even possible with httpDataCollector?  Is there any way at all to do it with ONMS or am I trying to fit a square peg into a round hole?

 

Thanks-

Jay

Monitoring Samba?


Hi there,

I'm attempting to add a Samba monitor to my existing OpenNMS instance. I'm
following the instructions here:

http://www.opennms.org/wiki/SMB_Service_Poller

but it's not detecting any SMB servers, and I'm not even seeing any traffic
when I sniff port 445 on one of my SMB server machines. Here's the relevant
config stuff:

-- capsd-configuration.xml --
...
<protocol-plugin protocol="Samba"
    class-name="org.opennms.netmgt.capsd.plugins.SmbPlugin"
    scan="on" user-defined="false" />
...
<smb-config>
 <smb-auth user="monitor" password="monitor"
    type="domain">MYDOMAIN</smb-auth>
</smb-config>
-----------------------------

-- poller-configuration.xml --
...
<service name="Samba" interval="300000"
    user-defined="false" status="on">
   <parameter key="retry" value="1"/>
   <parameter key="timeout" value="3000"/>
   <parameter key="port" value="445"/>
</service>
...
<monitor service="Samba"
   class-name="org.opennms.netmgt.poller.monitors.SmbMonitor"/>
------------------------------

I cranked up the debugging on capsd and it complains thusly:

SmbPlugin: nbtAddr.getHostNamer(): 10.99.42.37
SmbPlugin: SmbPlugin: failed to retrieve SMB name for 10.99.42.37

I'm not sure what this means, and I can't find anything in the source or in
Google to shed any light on this particular problem. Has anyone else seen
this before? Any suggestions for where to start twiddling knobs? I was
running a packet sniffer on the server in question, and I didn't see any
traffic on UDP ports 137-138 or TCP ports 139 and 445, so I'm not even sure
what OpenNMS is even doing since it doesn't appear to be talking to the
server.

thanks,
Klaus

This Week in OpenNMS: Lies, Damn Lies, and Release Dates

So I guess it’s been a while since the last TWiO, we’ve been pretty dang busy. I’m told I should call it “TQiO” (This Quarter In OpenNMS). Matt says “Well, you don’t call it *Every* Week in OpenNMS, just *this* one.” Touché.

Aaaaanyways, without further ado, here’s what we’ve done since, uh, well, May 16th. =)

Dev-Jam 2011

We had a total blast at Dev-Jam 2011. If you’re interested in catching up on what went on, check out Tarus’s Dev-Jam blog posts.

OpenNMS 1.10

We’ve been slowly working our way towards a 1.10 release candidate. The only things left are to go over the remainder of the IPv6 infrastructure (which I am spending this week on), and to then spend some time giving some attention to pending stuff in JIRA.

At the high level, there is a lot of exciting stuff coming in 1.10:

IPv6 Support The obvious one: support for IPv6. We have done a ton of work to add support for passing around IPv6 addresses in the code at all levels, as well as adding specific support for ICMPv6.

We’ve actually got 2 different strategies for IPv6 ping:

  • JNA – Uses embedded native code which is distributable. This means that ping will be supported from remote pollers!
  • JICMP6 – A port of the our internal JNI ICMP code to support IPv6. This will be the default in 1.10 for polling ICMP, as it is faster than the JNA implementation.
Reporting The new JasperReports-based reports introduced later in the 1.8 series has gone through a ton of improvements in 1.10, including a number of new reports, support for passing arguments to reports (date ranges, etc.), and other nifty stuff. Many other general updates to the reporting infrastructure have been added as well. Installer Updates The Liquibase database upgrade tools introduced in 1.8 have been updated to the latest (2.0.1) version, which is considerably faster than the 1.9.x version we used previously. New XML Processing Infrastructure While we haven’t finished converting all of our code to use it, we have started moving our Castor-based XML processing code to use JAXB instead. This provides a speed improvement when processing XML (including events posted to Eventd). This includes support for validation of inputs in the ReST interface. Drools Support is Back OpenNMS used to have support for using Drools for doing complex correlation of events. Due to dependency conflicts with other things we used in OpenNMS, it has been non-functional for quite some time. As of 1.10, this facility is working again, and will let you create code or scripts to do event correlation. Examples of a simple event correlation can be found in the $OPENNMS_HOME/etc/examples/ directory. UI Updates Many new UI changes have been made which give searchable controls for reports, nodes, etc., thanks to Donald’s new code for embedding GWT widgets in the OpenNMS UI. Instrumentation Log Reader Philip’s Instrumentation Log Reader tool has been updated with a number of new features, including sorting. It’s a great way to investigate data collection issues. Syslogd Improvements The Syslog infrastructure has been retooled to support a wider variety of input styles, as well as providing more optimized parsers for the most common Syslog formats. Using one of the specific parsers (Syslog-NG or RFC 5424) should provide performance improvements for handling large amounts of Syslog messages. Data Collection and Thresholding Updates Many improvements to data collection and thresholding have been made, including support for using regular expressions against column names when determining data to persist. Also, data collection configuration files have now been split like events are. Many New Detectors We’re adding detectors for everything that has a Capsd plugin, so you should be able to completely migrate to Provisiond. Provisiond Updates The provisioner has had a number of updates, including:
  • UI changes
  • Support for enabling or disabling polling and data collection through policies
  • Support for scanning the IP-MIB ipAddressTable, which detects IPv6 interfaces on an SNMP-enabled device
  • Updates to the DNS requisition import including IPv6 support, support for specifying the default services to apply to DNS-imported nodes, and the ability to determine how to compute the foreign ID (“ipAddress” or “nodeLabel”).

This is not an exhaustive list, but just what I came across doing some ‘git diff’ magic between the 1.8 and 1.10 trees. For a giant list of all of the issues closed against 1.10, see this link.

Project Updates

  • 1.8: Current Release is 1.8.12 (Black-capped Petrel)
    1.8.12 is the current stable release, tagged 10 May, 2011. For a complete list of changes and updates, see the “New and Noteworthy” page on the OpenNMS wiki. As always, it is recommended that you back up your database before upgrading.
  • 1.9: Current release is 1.9.8 (Pulalu)
    1.9.8 is the current unstable release, tagged 10 May, 2011. This release is not recommended for production use, but for developers and users who want to try out the very latest features. For a list of changes and updates, see the “New and Noteworthy” page on the OpenNMS wiki.
