Historical data is nice, but it's real-time data that gets the blood pumping. So, we took a close look at LiveHealth from Concord Communications. LiveHealth collects real-time data and reports it in an easy-to-understand, comprehensive and timely fashion. Like any new product, LiveHealth has its pros and cons. It produces excellent reports and supports more than 500 kinds of SNMP-aware devices. But it can't display a network's topology, doesn't offer corrective actions, and wasn't all that easy to install. LiveHealth starts at $35,000, and is part of Concord's suite that includes Network Health, System Health and Application Health modules. LiveHealth actively polls SNMP-manageable devices, determines their status and condition, and displays the result in real time. LiveHealth can present its reports via a browser-based interface, a server-based console and Adobe Acrobat-based reports. It also can send device status and condition data to network management products such as Hewlett-Packard's OpenView. LiveHealth is complex software. In addition to its sophisticated network monitoring and reporting elements, it comes with the CERN Web server for rendering management data and reports as Web pages, an Open Ingres database engine for storing network device data, and The Santa Cruz Operation's XVision PC Xserver, which LiveHealth's server console uses to display screen data. LiveHealth's discovery process is quick and accurate. By default, LiveHealth discovers network nodes daily at midnight. At 5-minute intervals (or less often, if you wish), the SNMP polling process probes the condition and status of network devices. LiveHealth understands a plethora of Management Information Bases, and it correctly recognized Lucent and Cisco routers, Samsung and 3Com switches, and the other devices in our test network. LiveHealth can tell you if a device is performing as it's supposed to, but it can't produce graphical maps showing network hierarchies. It stores collected network device information for six weeks in the Open Ingres database. In its first few days, LiveHealth builds a baseline of normal network behavior. Then, it can detect out-of-the-ordinary events, such as excessively high or low traffic through a router or switch port. Once LiveHealth detects a problem, a network administrator can choose to monitor the problem device in what Concord calls "fast mode." LiveHealth polls the device in frequencies up to twice a minute to help the administrator track the situation. LiveHealth doesn't offer external alerting functions, such as e-mail or paging, but relies instead on links to third-party programs (such as HP's OpenView) to provide such notifications or take corrective actions. The strength of the program is reports that show device information by time period, relationship to the organizational structure and type of behavior or exception. We could see devices that had experienced problems, by type of problem, as well as those associated with a particular application. LiveHealth runs on HP-UX, Solaris, Windows NT and 2000. The documentation is comprehensive, but should include a better roadmap to help users find the various software component discussions in the manuals. LiveHealth's installation was more difficult than we expected, but we found that LiveHealth's focus on performance and its extensive reporting are just what the doctor ordered.
