HP OpenView Network Node Manager



HP had the best discovery of all the products we tested. That said, you've heard the saying, "Close only counts in horseshoes and hand grenades"? Well, add network management to that list. HP would likely have tied for the top spot in this review had its event correlations worked during our testing. Too bad, because otherwise, even though HP charged the full $10,000, Network Node Manager kicks ass!

NNM promised to have the best fault management in this test, but we ran out of time before we could get it to deliver. At this writing, and despite much back and forth with technical support, some of the event correlation included with NNM was not working.

In addition to a filtered set of event consoles that sort events into categories, such as error, threshold, status and application, NNM provides extensive event parsing and editing, and correlation of event streams. NNM's event parsing is very similar to CA's, offering variable replacement, event text editing for clarity, and extensive Boolean logic to filter, delete and correlate. Also similar to CA, this feature takes time--and often money, in the form of professional services and training--to get up and running.

NNM has addressed this by offering canned correlation services, aptly dubbed Event Correlation Services, that promise to filter, interrelate and suppress unwanted and duplicate alarms. The configuration is accessible through a Web-based ECS viewer.
