Class SampleAgent

- org.snmp4j.agent.db.sample.SampleAgent

- All Implemented Interfaces:
org.snmp4j.agent.AgentStateListener<org.snmp4j.agent.AgentConfigManager>
public class SampleAgent extends java.lang.Object implements org.snmp4j.agent.AgentStateListener<org.snmp4j.agent.AgentConfigManager>
The SampleAgent uses anAgentConfigManager
instance to create a minimal SNMP agent using the configuration defined bySampleAgentConfig.properties
in this package. That properties file defines the initial content of the registered MIB objects of this agent which may differ from the hard coded defaults.This
SampleAgent
uses theMOXodusPersistenceProvider
to persistently storeManagedObject
s. It assumes that all managed objects that are non-volatile are implementing theRandomAccessManagedObject
interfaces.The agent uses the console logging to log messages.

main
public static void main(java.lang.String[] args)
Runs a sample agent with a default configuration defined bySampleAgentConfig.properties
. A sample command line is:-c SampleAgent.cfg -bc SampleAgent.bc udp:127.0.0.1/4700 tcp:127.0.0.1/4700
- Parameters:
args
- the command line arguments defining at least the listen addresses. The format is-c[s{=SampleAgent.cfg}] -bc[s{=SampleAgent.bc}] +ts[s] +cfg[s] #address[s<(udp|tcp|tls):.*[/[0-9]+]?>] ..
. For the format description seeArgumentParser

agentStateChanged
public void agentStateChanged(org.snmp4j.agent.AgentConfigManager agentConfigManager, org.snmp4j.agent.AgentState newState)
The agent state has changed to the new state as provided.- Specified by:
agentStateChanged
in interfaceorg.snmp4j.agent.AgentStateListener<org.snmp4j.agent.AgentConfigManager>
- Parameters:
agentConfigManager
- the agent's configuration manager. Use this object to access all agent resources, if needed to process this event.newState
- the new state of the agent. Although the listener may advance to agent state further, it is not recommended to do so, because theAgentConfigManager
will do it anyway.
