edit] Q: How To Configure Thresholds Within OpenNMS?

FAQ-Configuration - OpenNMS
Let's assume that we want to send an alert when hrSystemProcesses exceeds 250. The numeric OID is .1.3.6.1.2.1.25.1.6 . In this case, said collection definition is listed in my "/opt/OpenNMS/etc/ datacollection-config.xml" file. So what we need to do firstly is edit: "/opt/OpenNMS/etc/thresholds.xml".

edit] Q: How Do I Configure OpenNMS/Tomcat to Use SSL?

FAQ-Configuration - OpenNMS
First create a certificate keystore for tomcat by executing $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA Restart httpd, tomcat and opennms just to be sure and after what seemed too long, I was prompted for user name and password. It seems only the first time connecting is real slow, subsequent logins are quite speedy. I wanted to add a few comments to this. First, if you want to use a password other than "changeit", add the keystorePass attribute: <Connector className="org.apache.

edit] Q: How do I configure Net-SNMP to work with OpenNMS?

FAQ-Configuration - OpenNMS
By default, net-snmp is configured only to allow a really small amount of information to be accessed by the default community name of "public". The easiest way to change this is to find a line like: view systemview included .1.3.6.1.2.1.1

edit] Q: What is OpenNMS?

FAQ-About - OpenNMS
OpenNMS, the application, is the first enterprise-grade network management platform to be developed under the open-source model. The goal is for OpenNMS to be a truly distributed, scalable platform for all aspects of the FCAPS network management model, and to make this platform available to both open source and commercial applications. Data Collection - collecting, storing and reporting on network information as well as generating thresholds.

edit] Q: What language(s) is OpenNMS written in?

FAQ-About - OpenNMS
OpenNMS is mainly written in Java. The goal for OpenNMS 2.0 is to have a product that will install as a collection of .jar files. icmpd - The 1.4 Java API does not understand ICMP. Since ICMP echo requests ("pings") are the simplest way to test the responsiveness of an IP-based network device, no network management application will be complete without it. The goal is to separate the ICMP functions into their own daemon that OpenNMS will use if present and ignore if not.

edit] Q: How Do I Get OpenNMS to Collect Data from All SNMP Interfaces?

FAQ-Configuration - OpenNMS
With OpenNMS 0.9, the concept of a "primary" SNMP interface was added to the database. By default the interface with the lowest IP address is designated as the primary interface for SNMP queries. Also by default, performance data is only collected for that interface. If you would like to collect data on all of the interfaces on the node, you need to make a change to the /opt/OpenNMS/etc/datacollection-config.

edit] Q: Can I run OpenNMS as a non-root user?

FAQ-Configuration - OpenNMS
The difficulty with the core of OpenNMS is that these components need to run as root to be able to bind to low-numbered ports or generate network traffic that requires root: Here is an example of the error you will get if you try to startup OpenNMS as a non-root user: 2004-08-28 09:47:14,405 ERROR [main] Discovery: Failed to create ping manager: \ java.net.SocketException: System error creating ICMP socket (1, Operation not permitted)

edit] Q: How can I use OpenNMS to send pages?

FAQ-Configuration - OpenNMS
OpenNMS already has configurations to use qpage (http://www.qpage.org). You can see them in $OPENNMS_HOME/etc/notificationCommands.xml. I set up users on onms, then setup the users (with the same name) in /etc/qpage.cf. That's pretty much all I had to do in onms. On the qpage side, you need to configure the pager-ids and the service. The key here is that the number used to send alpha pages is not the pager number but a different number talking something called TAP.

What is a RADIUS Server?

FAQs | Xwire
RADIUS (Remote Authentication Dial-In User Service) is used for centralizing network authentication of remote access users. When you connect to an ISP you must enter your user name and password. This information is passed to a RADIUS server, which checks that the information is correct, and then authorizes access to the ISP system. RADIUS includes three components: an authentication server, client protocols, and an accounting server.
