I wanted to try out OpenNMS for monitoring our server infrastructure, and need to install PostgreSQL as described in the Installation manual.

Everything worked as described, except for one item during the installation of PostgreSQL: Trying to execute the command

initdb -E UTF-8 -U postgres ..\data

resulted in the error message

initdb: could not access directory "../data": No such file or directory

It turns out that initdb seems to have a problem with spaces in directory names (“Program Files”). Replacing the path with short filenames (“Program~1″) solves the problem Defining a path without any spaces solves the problem:

initdb -E UTF-8 -U postgres \databases\postgresql\8.3\data

Success!

Okay, Alhamdulillah akhirnya saya bisa posting cerita tentang kerja praktik juga. Setelah beberapa saat sebelumnya cerita yang ingin saya tampilkan direbut semua ma putat. T.T

Seperti yang teman2 udah baca sebelumnya, KP kami ini emang bisa disebut sebagai KP Daud. Nah lho..apaan tuh? Berhubung ada kebijakan seperti ini :

Nandya & Putat (NP) : “Pak, aturan disini seperti apa ya?”
Pembimbing KP (PKP) : “santai aja. disini kalian gak perlu setiap hari masuk. ya kalo kalian butuh riset silakan aja ke kantor.”
NP : “(terdiam membisu saling menyimpan tanya), oh baik pak, terimakasih.“

Dan, alhasil dari 5 hari waktu kerja, kami hanya 4 kali masuk ke kantor..:))

Oke, mungkin kebanyakan ya pembukanya..langsung mulai cerita aja deh..

Seperti yang diceritain putat waktu itu..kami diminta untuk membuat customize dari sistem yang dinamakan OpenNMS (Open Network Management System). Karena perangkat lunak ini bersifat Open Source, perih hati ini rasanya kalo harus menggunakan OS yang gak Open Source. Jadi we (aja .RED) kita make OS yang Open Source. apa tuh??

ini dia !!

Ubuntu's Logo

FAQ :

Q : Nan, tat, lambang naon eta?
A : Ubuntu ieu..

Q : Ubuntu teh naon? usus buntu?
A : arrgghh..dodol maneh..eta teh open source OS!

Q : open source OS? naon deui eta??
A : …… tanyakeun google we lah..

ya..jadi kami akan menggunakan OS Ubuntu untuk melakukan proyek ini. Berhubung kami awam banget dalam penggunaan Ubuntu, jadi ya beberapa hari pertama bener2 digunain buat mempelajari si Ubuntu tea (itu .RED). Dan akhirnya di hari keempat, kami berhasil meng-instal OpenNMS di Ubuntu.

FYI, cara meng-instal suatu program di Ubuntu jauh berbeda dengan meng-instal program di Windows. Sekedar berbagi pengalaman, saya akan menuliskan bagaimana prosedur meng-instal software OpenNMS di Ubuntu. Fasten your seatbelt and relax!!

1. Langkah pertama yang harus dilakukan adalah menambahkan daftar repository list pada file ” /etc/apt/sources.list “
deb http://debian.opennms.org stable main
deb-src http://debian.opennms.org stable main

2. Kemudian, setiap software dalam Ubuntu butuh yang namanya PGP Key (PGP Key adalah penanda author dari pencipta software-nya). Nah, setelah ini kita tambahkan deh PGP Key-nya..
$ wget -O – http://debian.opennms.org/OPENNMS-GPG-KEY | sudo apt-key add -

3. Abis itu, kita mulai deh meng-update repo-nya (repo ya, bukan reepooh)
$ sudo apt-get update

4. And then, snap snap snap, kita bisa mulai menginstal repository ini. gunanya apa? untuk mencegah dependency error..
$ sudo apt-get install sun-java6-jdk tomcat5.5 tomcat5.5-webapps tomcat5.5-admin
$ sudo apt-get install postgresql-8.3 iplike-pgsql83
$ sudo apt-get install opennms-common opennms-webapp opennms-server opennms-db jrrd jicmp

Hufffhhh..Capek ya? ini masih belom apa-apa lho..sekarang saatnya mengkonfigurasi Java-nya..

5. Konfigurasi default program untuk menjalankan java-nya adalah sebagai berikut :
$ sudo update-alternatives –config java
$ sudo update-alternatives –config javac
Seperti khotbah jumat tadi, khatibnya bilang “Segala sesuatu di dunia ini adalah pilihan”. Dan saya menyarankan untuk memilih pilihan SUN apabila teman-teman setelah melakukan instruksi yang terakhir dihadapkan pada pilihan yang membingungkan.

6. Kemudian mari kita tambahkan text di bawah ini di file /etc/environment
JAVA_HOME=”/usr/lib/jvm/java-6-sun”
JDK_HOME=”/usr/lib/jvm/java-6-sun”

7. Restart /etc/environment
source /etc/environment

Saatnya mengkonfigurasi tomcat5.5 :

8. Ubah port number menjadi “8080” Dari defaultnya di “8180” di file /etc/tomcat5.5/server.xml

9. Restart tomcat5.5
$ sudo /etc/init.d/tomcat5.5 restart

Konfigurasi PostgreSQL8.2

10. Buka file /etc/postgresql/8.2/main/pg_hba.conf. Tambahkan tulisan di bawah ini sebelum kata DO NOT DISABLE
#TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
local all all trust
host all all 127.0.0.1 255.255.255.255 trust
host all all ::1 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff trust

11. Buka file /etc/postgresql/8.2/main/postgresql.conf Uncomment tulisan
listen_addresses = ‘localhost’

Konfigurasi OpenNMS

12. Tambahkan di file /etc/environment
OPENNMS_HOME=”/usr/share/opennms”

13. Restart /etc/environment
source /etc/environment

14. Set up Java Virtual Machine-nya
$ sudo $OPENNMS_HOME/bin/runjava -s

15. Install OpenNMS nya
$ sudo $OPENNMS_HOME/bin/install -disU -l /usr/lib/jni:/usr/lib
Kalo berhasil, akan tampil tulisan :

Installation Succeed
(atau semacamnya,, lupa)

16. Install install_iplike.sh
$ sudo /usr/sbin/install_iplike.sh

Ingin tahu apakah berhasil atau tidak? nih ada kuncinya..kalo berhasil, nanti bakal ada tulisan :

CREATE FUNCTION

tapi, kegagalan mungkin aja terjadi. dan tanda-tandanya adalah terminal akan meminta password posgresql..

17. Lakukan konfigurasi pada file-file di bawah ini
# sudo nano /etc/opennms/discovery-configuration.xml
# sudo nano /etc/opennms/snmp-config.xml

Konfigurasi Tomcat

18. Ubah file /etc/default/tomcat5.5 Lalu ubah dan uncomment beberapa baris menjadi
TOMCAT5_USER=root
JAVA_HOME=/usr/lib/jvm/java-6-sun

19. Lakukan perintah instalasi lagi untuk set up webapp pada Tomcat
$ sudo $OPENNMS_HOME/bin/install -l /usr/lib/jni/ -y -w /var/lib/tomcat5.5/conf/Catalina/localhost

Konfigurasi akhir

20. Restart Tomcat, PostgreSQL, dan OpenNMS
$ sudo /etc/init.d/tomcat5.5 restart
$ sudo /etc/init.d/postgresql-8.2 restart
$ sudo /etc/init.d/opennms restart

Yihaaa, Done!! yes yes yesssss!! it’s done!!!

Mungkin sekian dulu lah ilmu yang kami bagi ini…nanti Insya Allah kalo ada perkembangan kite kabar2in lagi ye..selamat KP teman-teman semua…

On Ubuntu:

If OpenNMS is using the wrong time zone to display the current date add

export TZ=`cat /etc/timezone`

to /etc/init.d/opennms

Zo af en toe moet je eens wat nieuws testen, deze week was het tijd voor opennms, een monitoring tool dat je in netwerk kan scannen en meldingen kan geven als er problemen zijn.

Op het werk zijn we al een aardige poos bezig met Nagios en sinds een wat kortere periode met Cacti. Cacti is in eerste instantie een systeem dat via snmp get’s informatie over systemen kan ophalen. Dat kan verschillen van diskspace tot aan het aantal ingelogde gebruikers en nog heel veel andere zaken. Nagios is een applicatie dat actief en passief systemen kan checken met daemons.

Opennms is, voor zover ik het in een paar uur heb kunnen beoordelen een combinatie van beiden. Het kan, zoals met Nagios, meldingen per e-mail en sms naar gedefineerde gebruikers gooien. Daarnaast kan het vanaf het eerste moment gelijk grafische informatie geven zoals cacti dat ook wel doet.

De grote verrassing zat er bij mij vooral in dat opennms default al leuke zaken kan monitoren. Ook zaken als Oracle en MS Exchange kan het monitoren. Bij die laatste opties moet je wel weer jdbc drivers laden en ook de queries erachter zelf schrijven maar vanaf dat moment krijg je degelijke informatie. Dit is in principe ook mogelijk met Cacti maar uit ervaring weet ik dat de poller die in php is geschreven over zijn nek gaat als je redelijk veel nodes moet afgaan.

Het grootste voordeel op dit moment lijkt vooral dat het een combinatie is die zowel kan waarschuwen en rapporteren in een grafisch model. Daarnaast ziet het uit de doos al allerlei zaken als netwerkconnecties naar andere lan’s enzo. De komende weken ga ik er zo af en toe eens mee stoeien en zal dan bekijken of we het echt gaan inzetten.

OpenNMS is an enterprise-grade network monitoring platform developed under the open source software model. It consists of a community-supported, open-source project as well as an organization offering commercial services, training and support. (Wikipedia)

Features

• Service polling – determining service availability and latency, including distributed measurement of availability and latency, and reporting on the results
• Data collection – collecting, storing and reporting on data collected from nodes via protocols including SNMP, JMX, HTTP, and NSClient
• Thresholding – evaluating polled latency data or collected performance data against configurable thresholds, creating events when these are exceeded or rearmed
• Event management – receiving events, both internal and external, including via SNMP traps
• Alarms and automations – reducing events according to a reduction key and scripting automated actions centered around alarms
• Notifications – sending notices regarding noteworthy events via e-mail, XMPP, or other means

What is CheckStyle:

Checkstyle is a development tool to help programmers to write Java code that adheres to a coding standard. It automates the process of checking Java code to spare humans of this boring task. This makes it ideal for projects that want to enforce a coding standard.

Checkstyle is highly configurable and can be made to support almost any coding standard. An example configuration file is supplied supporting the Sun Code Conventions. As well, other sample configuration files are supplied for other well known conventions.

A good example of a report that can be produced using CheckStyle and Maven

I prefer to use geosoft java coding conventions always. You can download CheckStyle from here.

Procedure to integrate CheckStyle with OpenNMS Maven:

I believe us all familiar to use Maven. So I am just directly going for CheckStyle integration.

While compiling OpenNMS code I used CheckStyle to generate Static code Analyze report.

To generate the Checkstyle report as part of the Project Reports, add the Checkstyle plugin in the <reporting> section of openNMS root pom.xml .

<project>
  ...
  <reporting>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-checkstyle-plugin</artifactId>
      </plugin>
    </plugins>
  </reporting>
  ...
</project>
 
I used geosoft check file so I changed the above configuration as per my need

 

Then, execute the site plugin to generate the report. Use the following command in command line.

mvn site

We can also generate the Checkstyle report by explicitly executing the checkstyle:checkstyle goal from the command line. It is not required to specify the Checkstyle plugin in your pom.xml unless you want to use a specific configuration. . Use the following command in command line.

mvn checkstyle:checkstyle

To specifically configure the Checkstyle plugin, we need to add it in the <build> section of your pom.xml as shown in the sample below.

Note: The generated report will be saved under target\site folder of each project folder. example : opennms-model\target\site

Hi All,

From last week I just started to work with OpenNMS. It’s such a wonderful web based network discovery tool. It has lot of features then other NMS products.

I downloaded the version 1.5.91 from OpenNMS download server. Compiled with maven and added with eclipse workbench. Every thing works fine except mail notification. After some RND on this, finally i solved the problem. I used gmail smtp server.

All open NMS configurations related files are found under etc folder of openNMS. To enable mail notification we need to do some changes in the configuration files.

Edit Javamail-configuration.xml to set SMTP information

org.opennms.core.utils.fromAddress=frommailid@gmail.com

org.opennms.core.utils.useJMTA=false

org.opennms.core.utils.transport=smtp

org.opennms.core.utils.mailHost=smtp.gmail.com

org.opennms.core.utils.smtpport=587

org.opennms.core.utils.smtpssl.enable=false

org.opennms.core.utils.authenticate=true

org.opennms.core.utils.authenticateUser=tomailid@gmail.com

org.opennms.core.utils.authenticatePassword=password

org.opennms.core.utils.starttls.enable=true

org.opennms.core.utils.messageContentType=text/html

org.opennms.core.utils.charset=UTF-8

Edit notifd-configuration.xml to enable notification

status=”on”

Example:
notifd-configuration
status=“on”
pages-sent=”SELECT * FROM notifications”
next-notif-id=”SELECT nextval(‘notifynxtid’)”
next-group-id=”SELECT nextval(‘notifygrpid’)”

User mail configuration for notification:

As per your need you can configure the duty schedules.

Example:

Group configuration for notify:

As per your need you can configure the duty schedules.

Example:

When my node is down, i got a email notification. please see the below mail.

Hace unos días, un amigo experto en redes que trabaja con una gran empresa de telecomunicaciones, me expresó una de las preocupaciones más comunes con las que me he encontrado durante mis últimos años de trabajo. Cómo gestionar y monitorizar cada uno de los dispositivos incluidos en cualquier red, sea del tamaño que sea, controlando el rendimiento desde un simple ordenador con un router de banda ancha a una red de más de 10000 equipos y servicios.

There have been a few questions, occasionally, asking how to get users to view the “overview” or “status” page of OpenNMS, without actually logging in.

Well, the easiest for me, was to just design my own status page for my users. This way, I just sent a SQL query, and formatted the results. All you have to do, is just look at the ‘outages’ table, and return the data where the ‘ifregainedservice’ is null. This will return current outages, just like this:

select * from outages where ifregainedservice is "";

Of course, this won’t give you everything. That will just give you the IP Address of the device and the time it went down. You’ll want to join using either nodeid for Node-level data, or serviceid for Service-level data, or both.

Why do I call that simple? I mean, you have to design your own web page, write the database access, etc etc. Well, I’m making an assumption that if you are large enough business to warrant a self-access status page, then you are large enough to have an existing Internet or Portal, which pretty much already gives you this framework.

I could be wrong, in which case, I apologize. Maybe you can just write up a quick query in MS Access?

Of course, my number one request is to enable OpenNMS with WebServices. How cool would that be?? To make a web-request for the network latency graph, and plug it into your Portal? Sweeeet!

Cheers!
