Figure 14–1 shows the relationship between each managed UNIX or Linux system, the ULRM installed on it, and Operations Sentinel components. The agent receives events from the system logs and reports them to the Operations Sentinel server. Operations Sentinel Console displays them in its Alerts window.
The ULRM converts UNIX or Linux events to Operations Sentinel alerts. If the UNIX or Linux system is part of the current zone, Operations Sentinel Console includes these alerts with the zone alerts. If the system is not part of the current zone, Operations Sentinel Console includes them with the other alerts. Operations Sentinel handles these alerts in the same manner as other alerts.
ULRM Pipe
The named pipe of ULRM, /dev/ULRMPipe, provides a way for a client program written in any language to post events to the Operations Sentinel server. Use of the pipe is not limited to scripting languages since there are methods for opening named pipes in several programming languages. The program opens the named pipe and writes any type of event report to the pipe, using its particular language.
The ULRM continually monitors the pipe and forwards event reports to the Operations Sentinel server.
