Orion Network Performance Monitor (NPM) is what I call the 'big
tackle'. Big in its power to zoom into network trouble spots, and
big in the comprehensive range of checks that it manages. If you
are reviewing performance monitors, then take advantage of Solarwinds
offer to
download a free trial of Orion NPM v10.
Orion NPM is geared to detecting network outages caused by broken links
and faulty
equipment. Because it produces network-centric views, it's
intuitive to navigate and easy to see what's working and what's not.
Perhaps Orion's best feature is the way it suggests solutions.
Moreover, if problems arise out of the blue, then you can configure Orion
to notify members
of your team what's changed and how to fix it.
Please note: Orion NPM is not easy to setup for a network beginner.
However, even a minor network expert will have no trouble installing
Orion, and there again you can always get support from Solarwinds' experts
starting with the Thwack forum.
Once the Orion NPM v10 setup is complete then it's time to enjoy the
monitoring. I should not say this, but the greatest fun for a
techie is when something is wrong, but you can fix it easily.
With Orion NPM you start with a top-level network map and drill down
through the red dots to discover more about the symptoms. The cause of the
outage could be a broken physical link, a server that's offline, or an
application on a server that's run out of resources.

By using Orion NPM you will avoid amateur mistakes such as blaming
the network for latency problems, when it's really an
application on a server that is underlying cause. On a big
network a sub-contractor may have changed a router at a distant site, or
they patched a
server, only for the upgrade to cause a new far-reaching glitch.
Orion will help you detect and cure such problems.
Perhaps your company wiz-kid introduced a new VoIP or wireless
network, but did not realize the consequences for the rest of the
corporate network? Again Orion NPM will soon troubleshoot the root
cause, and more than likely suggest solutions.
Often the most frustrating problems are those that appear only sporadically.
For these annoying intermittent challenges Orion has an analyzer with retrospective
network-analysis capabilities. This historical data enables you to quickly
isolate and resolve the irregular network problem.
Summary Orion NPM will find the worst performing
device on your network.
No Solarwinds Orion review would be complete without mention of the top
ten lists. In fact, I find it mesmerising to observe how the nodes
change position and move in and out of the top 10.My favourite
category is response time, but you can also keep watch on:
Response Time (see screenshot right)
Wireless Clients by Traffic
Wireless APs by Client Count
Capacity
utilization
Memory usage
CPU load
Disk space volume
Network traffic and Packet Loss
I really enjoy customizing the lists so that Orion
monitors in just the way that I want.
Drill Downs
It soon becomes second nature to double click on the network maps and
drill down through the site level to the server. From there you
can even examine the
resource usage of individual devices. However, you are newbie,
this ability to locate problems is awesome and it feels like being at
NASA's mission control in Houston Texas.
The Underlying Polling Technology
Solarwinds Orion NPM ships
with a MIB database that covers all common network
devices. However, if you do have a non-standard Orion NPM allows
you to create a custom poller to monitor any SNMP-enabled device
value that has a MIB. As with so many of Orion's features, you can also
adjust how the module
collects and reports on the data.
For those with wireless networks, version 10 now has an integrated Wireless Poller.
And for those with VMware, Orion NPM reads host MIB information from
each VMware ESX server and its corresponding virtual machines.
Role-based Access Control
Orion Network Performance Monitor (NPM) allows you to fine-tune who
sees what information. Typically, at HQ you want to see
everything, but perhaps you want the team at the Boston site to see only
their own servers, and not start interfering with the New York
operations. See also my review of Orion
APM (Application Network Monitor).
EnergyWise
It would probably be over-playing your hand to say to your MD that energy
savings will pay for Orion NPM, but nevertheless, controlling the energy
consumption of Cisco EnergyWise-enabled network devices will reduce
costs, and could be a clincher in persuading the financial director to
buy Orion. For the techie it's just an interesting and worthwhile
challenge to reduce energy consumption and keep the server rooms cooler.

Time to Create Baselines
Creating baselines of network
activity is a good litmus tests of a well run company. Thus, one unexpected side-effect of using Orion NPM is that the techies
could have more time on their hands! As a manager you can take
advantage by commissioning them to show you baseline charts. The trouble with
fire-fighting is that you are never quite sure what is normal. By
having a 'feel' for the network backed up by stats for off-peak usage,
you can soon pin-point abnormalities. As a result you can either
prevent latency problems, or else cure them quickly before the users
realize there is something not quite right.
To support this pro-active approach to network management Orion
provides reports which are both comprehensive and interesting for the
techie. One common side-effect of baseline analysis is that ideas
for improvements
leap out of the charts, for example, load-balancing servers - one of my favourite
'cost nothing' tactics.
The most exciting new feature is Network Atlas. This topology
management feature combines sharp, accurate monitoring with detailed
reporting, and best of all it shows connections between devices.
Automatically discover new (rogue) devices added to your network.
Tell the truth, I am suffering version blindness, however I don't think
this ability to spot any extra devices that join your network existed in
v9.5. The benefit is that you scan every week or even every day to
see if anyone has added a device to your network.
It's only fair to point out when reviewing Solarwinds Orion performance monitors
is that the full package represents a big investment. Indeed, there are
cheaper performance monitoring packages, but they don't have the data
collection and storage capacity of Orion NPM v10. Actually, my
biggest discriminator in determining whether a product is cheap or
expensive is the quality of the support staff. Some people say
Orion is expensive, but nobody complains about the troubleshooting
skills of Orion's technical staff.
More good news is that Solarwinds offer of a trial version of Orion
NPM v10 so that you can see if this performance monitor really would save you money in the
long run. Another way of reducing costs is to select only the NPM
modules that you need. Once you see the benefits, particularly if
you are trying to track multiple sites, then it's easy to justifying
adding more options later.
There are cheaper alternatives to each Orion module, but one hidden
benefit of Orion is that all the modules integrate with each other,
which makes it so much easier for reporting and root cause analysis.
Also most rival products don't supply the level of detail that you get by drilling
down through the Orion Network maps.

Orion Network Performance Monitor is ideal for discovering
network trouble spots. When I tried he NPM I was surprised how
there was to learn about network technologies, fortunately the NPM
helped my understand an appreciate how devices communicate. If you
