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.

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".

Please note that we now keep up-to-date release notes on the web site and in the latest RPM packages, they may have information about installation on your particular distribution, or other last-minute things that went into the release. Before asking questions on the list, PLEASE check the release notes and this FAQ thoroughly for information pertaining to your issue.

We use SourceForge mailing lists. You can find links to subscribe as well as view archives on the web at our mailing lists page. Please note: when subscribing, remember the address you used, as you will need to send from that address or your post will be rejected. To unsubscribe, please do not send a message to the list or to the list administrator. Go to the list information page for the list you wish to leave, and enter in your e-mail address at the bottom and edit your options.

Then modify your notificationCommands.

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.

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)

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

You must setup the group and create the users. Also make sure that the pg_hba.conf file has the correct security permissions. And then just run psql interactively with these GRANTS for the group access.

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.

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.

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: Is the Postgres DB / SQL backend supported? A: A postgres/SQL backend was introduced in the 1.6 code line, but it never supported any features introduced since the 1.6 release, especially the Business features and Scheduled Transactions. Even so, modulo those features, the postgres backend should still basically function, even in the 2.2 release. However, since the 2.

There is none; all passwords are locked/scrambled by default; you set one yourself for those situations which call for it. You can set the root password by going to Knoppix Menu->Root Shell and typing "passwd", then entering a root password. In Version 5.0.1 you can also go to Knoppix Menu -> Configure -> Set password for root. There are several sections you can read dealing with this subject in KNOPPIX/README_Security.txt.

First of all, you have to have Knoppix installed on your hard drive. You won't be able to execute the following proceedure if you are running it from the CD. I beleve if you used a USB to hold the changes you make on a system couldnt you use that to watch a dvd? I imagine that would be more useable. Add the following lines to your /etc/apt/sources.list: deb http://www.videolan.org/pub/videolan/debian $(ARCH)/ deb-src http://www.videolan.

A: If the answer to this was documented, I never found it. I was having a very hard time because I put a lot of sprites on my screen. Small things ended up being behind large things (like trees). I could still see them just fine, but when clicking on them with the mouse, I would end up picking up the tree instead of the small rock behind it. I realized, don't use the mouse when you're placing sprites. It's not very precise and it's easy to move things a few pixels off.

In order to get more detail, open a Terminal from your system menu, and start gnucash at the prompt; this is almost always done by typing simply "gnucash" at the prompt. Save the detail emitted to the terminal (if any), as well as the contents of the /tmp/gnucash.trace file. edit] Q: I think I found a bug. How do I report it? A: First of all, try to verify that it is indeed a bug and that it has not been reported before.

GnuCash does not enforce any particular file naming convention or extension. However, the following extensions are described in the "shared-mime-info" package used by almost every distro and desktop environment to associate applications with files. Naming your datafile with one of these extensions will allow the gnucash to be opened when a file is seen and activated in a file browser. edit] Q: Where is my .

That is, is there a way to move all transactions from one account into another? That would save a lot of time compared to moving each transaction! A: Kind of. If you want all the transactions in one account to move/merge into another account, you can reparent the to-be-deleted account under to to-be-moved-into account, and then delete the to-be-deleted-account. GnuCash will ask you if you want to move the transactions, and you should answer "yes".

When editing the Child account (via "Edit Account"), you can select the parent Account. Thus, you can move Accounts up and down the tree, within the bounds of the account-type constraints. Yes, it would be nicer if one could simply drag and drop in the Account Tree. The Account Code field can contain any value you wish, which can be used in the Account Tree to sort the column and thus the rows. Unfortunately, this is a pretty heavy-handed sort that applies to the whole view, not just a sub-tree.
