Fault and Event Management
Fault and Event Management
There are several tools you can use to identify and manage problems and be alerted to
other significant events that occur in your network.
Monitoring EMS Messages
Event Management Service (EMS) on page 4-6 introduces the EMS product. You can
see displays of event messages on the system console by using the OSM Event
Viewer or TSM EMS Event Viewer. Also, other applications can retrieve messages
directly from EMS. You can use filters to programmatically select the subset of
messages that interest you by using NonStop NET/MASTER MS.
For example, if you are running HP NonStop TCP/IP over the SLSA subsystem, you
might want to monitor messages only from those two subsystems. If a certain device
seems to be malfunctioning, you can review the most recent events pertaining to that
device. You also have the option to monitor events as they occur or to review events
that have occurred since a specific time. The event logs that EMS maintains are useful
not only for day-to-day event management but also for longer-term network analysis.
EMS Analyzer
The EMS Analyzer product selects events from EMS log files. You specify parameters,
such as subsystem ID, event number, text, start time, and stop time. EMS Analyzer
allows you to examine and analyze information about the devices, subsystems, and
applications on your server, without having to write or compile you own filters using the
EMS filter language.
NonStop NET/MASTER MS
With NonStop NET/MASTER MS you can also view event information from SNA
systems on your network. SNAX subsystems support a mechanism called SNAView,
which allows passage of event information between NonStop S-series servers and
SNA systems. SNAView is described in Section 7, HP NonStop S-Series Systems
Network Architecture (SNA) Network Connections.
