Project Status
==============
More 0.4.x Info:
Effective today, 0.4.1 has been released, and it incorporates fixes to
a couple of bugs from 0.4.0. If you haven't gotten it yet, and you
aren't heavily invested in your 0.4.0 install yet, make life easier
for yourself--download the RPMs for 0.4.1 and install those.
I also wanted to take a minute and address some of the more common
questions that we've been getting. These answers will be pushed into
the FAQ at some point, hopefully sooner than later.
* Minimum System Requirements
P200, 256MB RAM, Linux, JDK 1.3+, OpenNMS
Yeah, it's a memory pig, but this is effectively an untuned first
release, so we're looking at that. And don't forget, this is
intended to scale WAY up, so it's going to need more system
resources than office apps. Look at the bright side, memory is
cheap
* Starting Things Up
0.4.1 includes the latest and greatest init scripts, which Ben is
quite proud of and embarrassed by, all at the same time. Big
thanks to those of you that contributed code and ideas and fixes
for our earlier scripts.
Also, keep in mind that OpenNMS is expecting the following rough
order for firing stuff up:
+ Postgres 7 is running
+ icmpd is running
+ /opt/OpenNMS/RunSCM.sh
+ /opt/OpenNMS/RunOpenNMS.sh
* Troubleshooting
If it is just not working, you can help everyone out a bit by
enabling a higher level of logging. This is pretty easily
accomplished by mucking with the "bluebird" properties file in
/opt/OpenNMS/data/common/properties/. Find the section on logging,
read the comment block, and then change the "logLevel" entries
appropriately. Also, note that the logs get written to
/var/log/opennms/.
Consider yourself forewarned: We enabled maximum logging on
discovery and let it run over night. In doing continuous discovery
of a small subnet overnight, our log file was over 70MB by the
next morning. Make sure you have plenty of disk space if you
decide to turn this on!
* Typical Errors
Depending on available system resources, we do generate errors
that have become pretty common for us, at least in our little
development testbed.
JSDT Timeouts: Typically indicates that for some reason the JSDT
Channel has gone away. Happens more often when you are constrained
for memory/resources.
JSDT NoSuchChannelException: Typically means that you've either
tried to start things out of order or something has mysteriously
gone away while you weren't looking.
* Buttloads of Java Processes
With the way Linux handles Java's native threads, every thread
shows up as a separate process to "ps". In limited testing, it
looks like a lightly loaded system will have around 420-450
processes alive as it runs. You can count yours with a "ps -ef |
grep -i java | wc -l". It may not be an official count, but since
the electoral college has already voted, it really doesn't matter
anyway...
And yes, "Buttload" is the scientific term for over 300 and less
than 1000 (in a process-counting context).
Getting Things Right:
This interim "Testdrive" release has proved to be a blessing in
disguise for many of our efforts. It seems that what we've been
missing to date is user feedback. Until this release, that was
impossible and now, we're starting to see some things that we didn't
consider earlier.
As a result, we're changing up our development efforts a little bit to
continue to focus on some of the problems inherent to the Testdrive
release that will impact the project moving forward. This will change
our delivery timeframes for the distributed architecture to some
extent, but it also ensures a much sounder release when distributed
architecture is announced.
Some of the things we're adding back to the development "To-do" list
includes performance data collection, easily customizable pollers,
white papers that provide a HOWTO on writing custom pollers, and
perhaps some further discussions on adding a web interface.
You ask--we deliver. Who could ask for anything more? (Other than
Toyota, of course.)
Coding Projects Underway:
* Servlets -- Actively working on building/tuning the "extractors".
* SCM -- Jason is introducing Pause/Resume functionality for the
schedulers. Once complete, we'll instrument all SCM processes with
this ability.
* TCP Poller -- Mike is working on a generic TCP service poller that
will read an XML file for its configuration (port info, banner
description, etc) and poll based on your configuration. Makes it
easier for you to poll your custom services and applications.
* Maji Prelim Work -- Rick is active on the "events" mailing list.
* Distributed Architecture -- Work continues...
===================
Curious Bostonians?
===================
Are you in the Boston area? Are you curious about OpenNMS from a
technical/business/strategic perspective?
Luke "Flip-flops" Rindfuss and I will be in the Boston area and thanks
to our ever-accommodating friends at the airlines, we have the
afternoon free on Thursday, Dec 21, 2000.
We can handle just about anything you'd like to do/know/argue, so if
you are looking for a presentation, a conversation, an excuse to
exercise your expense account, a way to kill the afternoon, or you
simply want to see the winter flip-flops, please advise.
So if you'd like to hook up, let us know. Otherwise, the airport bars
stand to make a killing.
=====================
New Features En Route
=====================
As mentioned earlier, we've got some neato stuff in the works. Here's
the 50,000 foot view:
* Generic TCP Poller: Poll services running on the port you
configure, looking for the response you configure to expect.
* Portable Agent Technology: We're early in the process of a
collaborative effort with another open source project to provide
an "agent" that will run on your systems to provide you a means to
remotely gather performance and system "health" information.
* Performance Data Collector: joeSNMP has been around for a while
now, and we're just about ready to push it into use. We'll be
building a configurable SNMP poller that will grab the various
data points we (or you) want and will slam them into a back-end
performance database.
* Distributed Architecture: This is a major effort and I didn't want
to leave it out. But the major buzz we're hearing now suggest that
some of these other items may be of greater importance to the
community at large, so we're not abandoning those in lieu of the
Distributed Architecture. It seems our full plates just got
moreso.
* Reporting: The data collection piece doesn't make a whole lot of
sense without the means to report on that data. This effort has
been underway for a while, but will require a slight dusting off
before we delve back into it. The good news is that some of the
XSLT stuff has revved since we were into this before, so some of
the bugs have likely been addressed.
* Bug Fixes: As you'd likely surmise, with actually having a a
functional product out the door, some people are finding bugs and
we're doing our best to get those fixes prioritized and into the
system where appropriate. Note that if the bugs are related to
some throw-away piece of the software (e.g., something that was
written to get the Testdrive release out the door and is not there
for the long haul), then there's a pretty good chance your bug
will be prioritized as "WONTFIX" and you'll hear very little back.
The good news is that you've got the source and you can fix your
own bugs if it comes right down to it. Open Source Rocks!
=============
The Wish List
=============
Given that the entire newsletter was pretty much dedicated to some of
the new efforts/features/fixes we're working on, a Wish List seems
pretty redundant at this point.
That said, I elect to forego the Wish List this week.
If there are features or fixes you'd like to see incorporated into
upcoming releases that I've not mentioned here, please let me know.
You can reach my jam-packed email box directly at shaneo@opennms.org .

Afterthoughts
=============
I like the thought of Christmas and all, but man, it's hell on
productivity. And it seems like when I do finally get a little bit of
time to myself, I'm either decorating something or buying something or
going somewhere, all Christmas related.
Here's an idea: how about we spread Christmas out over a few months,
and let's get it away from New Years and Thanksgiving--how about late
March. Now there's a month hurtin' for a holiday (Work holiday that
is. I've been lobbying for March 18th as Hangover Day, but haven't
gotten far. Although I haven't approached Teddy Kennedy yet...but
that's a different story)
Anyway, we move Christmas to late March (OK. Prove it to me that Jesus
was born on 12/25 and I'll back-off). Then, we put into place a set of
very particular rules about how it is celebrated. First off, no "Eve"
celebrations. Day of. Nothing else. Next, no decorating allowed. Trees
are allowed, but only fake ones. No more of this "Killin' trees for
Jesus" crap. I'm no tree-hugger, but the whole tradition does seem
rather insane when you think about it. And finally, all celebrations
on the day of New Christmas must be in one location and one location
only. If you have multiple places to go (your place and your
significant other's place) pick one and stay there. Tell the other
folks that you'll go there next year and that they should know the
rules.
In my mind, anyway, this buys us back time, productivity, and it gets
us a holiday in late March. Come to think of it, why don't we just
make it March 18th. We can kill 2 birds with one stone, and a lot
fewer trees.
Color me outta here,
Shane O.
