Sun Management Center 3.5 Update 1 Supplement for Halcyon PrimeAlert Agent for Linux

Module Features

The Linux Agent modules include:

These Linux Agent modules are loaded by default when the Linux Agent is first started.

Module Online Help

The Linux Agent modules have online help, which is accessed separately from the Sun Management Center online help.

To access the Linux Agent help, click the module name in the Module Browser tab. Then click mouse button 3 (right-click) and select Help from the pop-up menu that appears.

Note –

The illustrations in the Linux Agent help are not current with the Sun Management Center 3.5 Update 1 console. The illustrations do not show the View Logs, Applications, and Module Manager tabs. The View Logs and Applications tabs do not apply to the Linux Agent, but the Module Manager tab is functional. Also, the illustrations show the Module Browser tab as the Browser tab.

The help files are on the Sun Management Center server. In the following URLs, smc-svr:port 8080 is the Sun Management Center server running on port 8080. All of the help files have the following path:


http://smc-svr:8080/help/locale/C/

The help files are also in the doc subdirectory of the HALLinuxAgent_5.2.x directory in the tar file HALLinuxAgent_5.2.x.tar:

PrimeAlert SystemMonitor for Linux

The PrimeAlert SystemMonitor for Linux provides information about the operating system and its components. It is similar to the Kernel Reader Simple module of Sun Management Center. The following subfolders are available:

User Statistics

Displays information about the current console user, the number of current users and sessions, and the primary user of the system.

Process Statistics

Displays information about current processes on your Linux system grouped by their state. This subfolder also shows the total number of processes and the process capacity as well as the process limit. Probe commands provide a detailed view of processes in different states and ordered by several criteria.

System Load

Provides information about the current system load (1–minute, 5–minute and 15–minute load averages).

CPU Usage

Provides information about the current usage of the CPU. Shown are idle time, busy time, system time, user time, and the average CPU usage.

Swap Usage

Displays information about the total and available swap space and the current usage of swap memory. A probe command provides detailed information about allocated swap space.

Filesystem Usage

Displays information about mounted filesystems. For each filesystem, the total size, available space, used space, and the change rate of used space are shown.

Network Interfaces

Lists installed network interfaces and reports input/output packet errors and collisions. Probe commands can be used to obtain information about route tables and protocols.

TCP Connections

Provides information about existing TCP connections. Probe commands generate a detailed view of network statistics for several protocols (for example, Inet, TCP, and UDP).

IPC Facilities

Displays information about IPC message queues, shared memory, and semaphores.

PrimeAlert AgentHealth

The PrimeAlert AgentHealth module monitors statistics about the internal state of the agent and of the agent process. It is similar to the Agent Statistics module of Sun Management Center.

Note –

If the Memory Usage and Virtual Memory Size values exceed the Critical alarm thresholds, the agent exits automatically. The default is set to 70000 Kbytes for Virtual Memory Usage.

PrimeAlert MIB-II System

The PrimeAlert MIB-II System module delivers data for the system description, name, and uptime, as well as contact information and location. MIB-II stands for Management Information Base for Network Management of TCP/IP-based Internets and is a standard proposed by the Internet Architecture Board (IAB). The PrimeAlert MIB-II System module is similar to the MIB-II Simple module of Sun Management Center.
