telegraf/snmp

Monitor Type: telegraf/snmp (Source)

Accepts Endpoints: Yes

Multiple Instances Allowed: Yes

Overview

This monitor reports metrics from snmp agents. This monitor is based on the Telegraf SNMP plugin. More information about the Telegraf plugin can be found here.

NOTE: This snmp monitor does not currently support MIB look ups because of a dependency on net-snmp and specifically the commands snmptranslate and snmptable.

Sample YAML configuration:

monitors:
 - type: telegraf/snmp
   agents:
     - "127.0.0.1:161"
   version: 2
   community: "public"
   fields:
     - name: "uptime"
       oid: ".1.3.6.1.2.1.1.3.0"

Using a discovery rule to discover and configure for a specific snmp agent

monitors:
 - type: telegraf/snmp
   discoveryRule: container_name =~ "snmp" && port == 161
   version: 2
   community: "public"
   fields:
     - name: "uptime"
       oid: ".1.3.6.1.2.1.1.3.0"

Configuration

To activate this monitor in the Smart Agent, add the following to your agent config:

monitors:  # All monitor config goes under this key
 - type: telegraf/snmp
   ...  # Additional config

For a list of monitor options that are common to all monitors, see Common Configuration.

Config option Required Type Description
host no string Host and port will be concatenated and appended to the list of SNMP agents to connect to.
port no integer Port and Host will be concatenated and appended to the list of SNMP agents to connect to. (default: 0)
agents no list of strings SNMP agent address and ports to query for information. An example address is 0.0.0.0:5555 If an address is supplied with out a port, the default port 161 will be used.
retries no integer The number of times to retry. (default: 0)
community no string The SNMP community to use. (default: public)
maxRepetitions no uint8 Maximum number of iterations for reqpeating variables (default: 50)
contextName no string SNMP v3 context name to use with requests
secLevel no string Security level to use for SNMP v3 messages: noAuthNoPriv authNoPriv, authPriv. (default: noAuthNoPriv)
secName no string Name to used to authenticate with SNMP v3 requests.
authProtocol no string Protocol to used to authenticate SNMP v3 requests: "MD5", "SHA", and "" (default).
authPassword no string Password used to authenticate SNMP v3 requests.
privProtocol no string Protocol used for encrypted SNMP v3 messages: DES, AES, "" (default).
privPassword no string Password used to encrypt SNMP v3 messages.
engineID no string The SNMP v3 engine ID.
engineBoots no uint32 The SNMP v3 engine boots. (default: 0)
engineTime no uint32 The SNMP v3 engine time. (default: 0)
name no string The top-level measurement name
fields no list of objects (see below) The top-level SNMP fields
tables no list of objects (see below) SNMP Tables

The nested fields config object has the following fields:

Config option Required Type Description
name no string Name of the field. The OID will be used if no value is supplied.
oid no string The OID to fetch.
oidIndexSuffix no string The sub-identifier to strip off when matching indexes to other fields.
oidIndexLength no integer The index length after the table OID. The index will be truncated after this length in order to remove length index suffixes or non-fixed values. (default: 0)
isTag no bool Whether to output the field as a tag. (default: false)
conversion no string Controls the type conversion applied to the value: "float(X)", "float", "int", "hwaddr", "ipaddr" or "" (default).

The nested tables config object has the following fields:

Config option Required Type Description
name no string Metric name. If not supplied the OID will be used.
inheritTags no list of strings Top level tags to inherit.
indexAsTag no bool Add a tag for the table index for each row. (default: false)
field no list of objects (see below) Specifies the ags and values to look up.
oid no string The OID to fetch.

The nested field config object has the following fields:

Config option Required Type Description
name no string Name of the field. The OID will be used if no value is supplied.
oid no string The OID to fetch.
oidIndexSuffix no string The sub-identifier to strip off when matching indexes to other fields.
oidIndexLength no integer The index length after the table OID. The index will be truncated after this length in order to remove length index suffixes or non-fixed values. (default: 0)
isTag no bool Whether to output the field as a tag. (default: false)
conversion no string Controls the type conversion applied to the value: "float(X)", "float", "int", "hwaddr", "ipaddr" or "" (default).
