SNMP details for Linux

The fio-snmp-agentxSNMP agent is an RFC 2741-compliant AgentX subagent. It can work with any RFC-compliant SNMP agent, such as Net-SNMP.

The master SNMP agent defers queries to fio-snmp-agentxfor supported MIBs.

SNMP master agent

The fio-snmp-agentx, provided in the fio-utilpackage, requires an already-installed SNMP master agent. The SNMP master agent must support and be configured for AgentX connections. For more information, see the "AgentX Protocol Version 1 (http://www.ietf.org/rfc/rfc2741.txt)."

The fio-snmp-agentxis tested and verified with Net-SNMP, which is the typical SNMP agent provided with most Linux distributions. Several agents are available that support this functionality. The following sections describe Net-SNMP.

Launching the SNMP master agent

Install the Net-SNMPpackage using the package manager for your version of Linux.
