Fault management is one of Orion's weakest areas, but it does display events and alarms clearly, and you'll get value without heavy lifting. However, you won't get advanced fault features, such as the support for traps or log files found in CA's and HP's products; and there are no canned correlations, like those found in HP's OpenView NNM, to suppress downstream events or deduplicate recurring events.
The event console can be displayed as a summary or detailed list, and events can be linked to the devices to which they apply. The summary display groups similar events, and a single click will clear an entire group--a useful feature after a losing a router, as it makes getting rid of all the interface alerts fast and easy. Because the interface is completely configurable, you can move these lists and summaries into any configuration.
Getting rid of all the node's up or down events made it possible to quickly set things back to zero, but that's also a dangerous command: It could make shift turnover easy while hiding the true status of the network. Of course, if shift turnover means you leaving and coming back, then no big deal.
When an alert is displayed, all of the relevant interface utilization and error statistics are, by default, displayed as well. Settings can be customized with a simple point-and-click from within the Web interface as long as you're logged on as administrator. Events can't be assigned, acknowledged or cleared by operators, though they can be cleared from the Win32 admin GUI. So, the software doesn't provide a workflow process that would let the Web interface be used by operators; this is limiting if you've got to roll the management product out to a number of folks.
The process of creating an alert is as simple as checking the appropriate metric and setting the threshold value. By default, all alerts are applied to all appropriate devices. The devices, as we expected, can display status, but what was nice is that the status can be displayed in different ways; that's in keeping with the flexibility we found throughout the Network Performance Monitor.
