PATROL for Linux contains the knowledge that PATROL uses during system monitoring, analysis, and management activities. This knowledge can include command descriptions, applicationsparameters, recovery actions, and other information useful in administering Linux systems.

The KM parameters allow you to perform system performance analysis quickly and easily because they can provide a detailed statement of all system activity through time. You can clearly identify peaks, troughs, and trends in the performance of system resources.

By enabling you to detect problems, optimize systems, analyze trends, plan for capacity, and manage simultaneous, multiple host, the KM helps you ensure that your Linux systems run efficiently 24 hours a day.

The components and products that are included PATROL for Linux are shown below.

 PATROL SNMP Component Definitions

Component

SNMP Role

BMC PATROL Agent

Generates traps

BMC PATROL SNMP Master Agent

Provides SNMP information to SNMP managers in the form of responses to SNMP queries

BMC PATROL SNMP Subagent

Responds to SNMP queries by going into internal data structures and sending information back SNMP subagents can also generate or send BMC PATROL traps directly to the SNMP Manager.

BMC PATROL SNMP Manager Functionality (PSL Functions)

Receives traps and issues queries to an SNMP agent The manager controls the agent by making SNMP requests of the agent and by setting variables in the agent's management information base (MIB).

PATROL Agent 

The PATROL Agent product for Linux is a core piece of the PATROL architecture and is used to monitor computers. PATROL Agents load information from Knowledge Modules (KMs), gather statistics, and send alerts and requested information to the PATROL consoles. PATROL Agents accept requests from the PATROL console and initiate actions based on those requests. 

Using information from a PATROL KM, a PATROL Agent can:

  • Detect the presence and status of an application instance (discovery)
  • Collect data on any measurable aspect of an application instance (parameters)
  • Interpret data by using defined rules
  • Act as a service provider for event management
  • Store collected data in local files (history)
  • Implement predefined actions to correct abnormal conditions (recovery actions)

You must install a PATROL Agent on each computer you want to manage. For more information, see the PATROL Agent Online Documentation.

PATROL Linux

The PATROL Knowledge Module (KM) product for Linux enables you to monitor and manage system resources in Linux environments. The PATROL for Linux can:

  • Monitor the percentage of used and free swap space on disks
  • Monitor CPU loads across a network
  • Automatically spawn recovery actions in your Linux environment
  • Monitor processes that are running on the system (process presence monitoring)
  • Monitor memory utilization and free memory
  • Monitor filesystem capacity
