MongoDB Documentation, Release 3.0.4 The configuration filename is tool-dependent. For example, when using net-snmp the configuration file is snmpd.conf . By default SNMP uses UNIX domain for communication between the agent (i.e. snmpd or the master) and sub-agent (i.e. MongoDB). Ensure that the agentXAddress specified in the SNMP configuration file for MongoDB matches the agentXAddress in the SNMP master configuration file. Step 2: Start MongoDB. Start mongod with the snmp-subagent to send data to the SNMP master. mongod --snmp-subagent Step 3: Confirm SNMP data retrieval. Use snmpwalk to collect data from mongod : Connect an SNMP client to verify the ability to collect SNMP data from MongoDB. Install the net-snmp 89 package to access the snmpwalk client. net-snmp provides the snmpwalk SNMP client. <port> refers to the port defined by the SNMP master, not the primary port used by mongod for client communi- cation. snmpwalk -m /usr/share/snmp/mibs/MONGOD-MIB.txt -v 2c -c mongodb 127.0.0.1:<port> 1.3.6.1.4.1.34601 You can run mongod with the snmp-master option for testing purposes. To do this, use the SNMP master configu- ration file instead of the subagent configuration file. From the directory containing the unpacked MongoDB installation files: cp mongod.conf.master /etc/snmp/mongod.conf Additionally, start mongod with the snmp-master option, as in the following: mongod --snmp-master New in version 2.6. SNMP is only available in MongoDB Enterprise$^{90}$. MongoDB Enterprise can provide database metrics via SNMP, in support of centralized data collection and aggrega- tion. This procedure explains the setup and configuration of a mongod.exe instance as an SNMP subagent, as well as initializing and testing of SNMP support with MongoDB Enterprise.
