Agent

Description

Apache

Brings an Apache Server online, takes it offline, and monitors its processes. Use the Apache Web server agent with other agents to make an Apache Web server highly available. This type of resource depends on IP and Mount resources. The Apache agent can detect when an Apache Web server is brought down gracefully by an administrator. When Apache is brought down gracefully, the agent does not trigger a resource fault even though Apache is down.

Application

Brings applications online, takes them offline, and monitors their status. Use the Application agent to specify different executables for the online, offline, and monitor routines for different programs. The executables must exist locally on each node. You can use the Application agent to provide high availability for applications that do not have bundled agents, enterprise agents, or custom agents. This type of resource can depend on IP, IPMultiNIC, and Mount resources. The Application agent supports both IMF-based monitoring and traditional poll-based monitoring.

Process

Starts, stops, and monitors a process that you specify. Use the Process agent to make a process highly available. This type of resource can depend on IP, IPMultiNIC, and Mount resources. The Process agent supports both IMF-based monitoring and traditional poll-based monitoring.

ProcessOnOnly

Starts and monitors a process that you specify. Use the agent to make a process highly available. No child dependencies exist for this resource.
