Agent Mode on UNIX

Under UNIX, the AE SNMP Subagent can run as Masteragent or Subagent.

Specify the mode in the INI-file parameter role= (section [SNMP]).

Masteragent (Recommended)

Advantages:

There is no need to install Net-SNMP.
Improved performance
Improved error insulation

Disadvantages:

Only AE monitoring starts.
No other MIBs are available.
The variable SNMPCONFPATH must be set. It contains the directory with the file ucsnmp1.conf (e.g: "export SNMPCONFPATH=./")

You can specify the same parameters in the file ucsnmp1.conf as in the net-SNMP agent's configuration file (snmpd.conf).

The AE SNMP Subagent uses the following parameters:

trapcommunity
trapsink
rocommunity
rwcommunity
master

An explanation of the individual parameters is available in the description of the snmp.conf provided by net-SNMP.

Example for the file ucsnmp1.conf:

trapsink host1 trapsink host2 rocommunity public master agentx

In Masteragent mode, no other Subagents can establish a connection to the SNMP Subagent.

Subagent

The AE SNMP Subagent cooperates with an existing Masteragent:

A Masteragent which is able to deal with AgentX must be started.
The standard communication medium is a local socket file which is stored in the directory /var/agentx/mastert. The Masteragent creates this file. The AE SNMP Subagent only requires the right to access it.
The configuration file snmpd.conf contains some settings:

Example for the file ucsnmp1.conf:

trapsink local
rocommunity public

HP-UX

The AE SNMP Subagent must operate on HP UX in Masteragent mode. The native Masteragent for the HP-UX system is EMANATE. The AE SNMP Subagent uses the naaagt interface to communicate to it. The naaagt interface serves as SNMP ProxyEigenes Produkt von Automic, das als zusätzliches Dienstprogramm mit der Automation Engine verwendet werden kann.Dienst der Zusammenfassung und Umleitung von CP-Verbindungen.. It redirects SNMP queries to a different UDP port via a registered OID. By default, the naaagt uses port 8161. Thus, the AE SNMP Subagent uses a different port.

Further information about configuring the interface is provided in the naaagt documentation.
