Enterprise Feature
SNMP is only available in MongoDB Enterprise.
MongoDB Enterprise can provide database metrics via SNMP, in support of centralized data collection and aggregation. 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.

mongod.exe
. Other MongoDB tools such as mongos.exe
do not support SNMP.mongod.exe
does not support the use of SNMP traps.MongoDB Enterprise contains the following configuration files to support SNMP:
MONGOD-MIB.txt
:
The management information base (MIB) file that defines MongoDB’s SNMP output.
mongod.conf.subagent
:
The configuration file to run mongod.exe
as the SNMP subagent. This file sets SNMP run-time configuration options, including the AgentX
socket to connect to the SNMP master.
mongod.conf.master
:
The configuration file to run mongod.exe
as the SNMP master. This file sets SNMP run-time configuration options.
Use the following sequence of commands to move the SNMP configuration files to the SNMP service configuration directory.
First, create the SNMP configuration directory if needed and then, from the installation directory, copy the configuration files to the SNMP service configuration directory:
The configuration filename is tool-dependent. For example, when using net-snmp
the configuration file is snmpd.conf
.
Edit the configuration file to ensure that the communication between the agent (i.e. snmpd
or the master) and sub-agent (i.e. MongoDB) uses TCP.
Ensure that the agentXAddress
specified in the SNMP configuration file for MongoDB matches the agentXAddress
in the SNMP master configuration file.
Start mongod.exe
with the snmp-subagent
to send data to the SNMP master.
Use snmpwalk
to collect data from mongod.exe
:
Connect an SNMP client to verify the ability to collect SNMP data from MongoDB.
Install the net-snmp 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.exe
for client communication.
You can run mongod.exe
with the snmp-master
option for testing purposes. To do this, use the SNMP master configuration file instead of the subagent configuration file. From the directory containing the unpacked MongoDB installation files:
Additionally, start mongod.exe
with the snmp-master
option, as in the following:
