While Telegraf's SNMP input has some advantages over other open source options, the simple fact is that it has serious deficiencies that make it almost useless for anything beyond the simplest low-scale use-cases. If I ever find an SNMP poller worth recommending I will note it here at that time.
influx_snmp provides a solution for SNMP data collection and analytics using InfluxData's TICK Stack - Telegraf, InfluxDB, Chronograf and Kapacitor.
To poll a device, a container of the appropriate type is configured and run. docker-compose provides a mechanism to easily configure and start multiple containers for the various devices in your infrastructure. An example docker-compose.yml file is provided, including an example of using a environment variable file to set global settings.
The containers are available on Docker Hub HERE.
The following is an example docker-compoase.yml file, which polls three different device type-specific containers:
version: '3'
services:
snmp-rt1:
image: robcowart/telegraf-snmp:0.0.1_ubiquiti_edgeos_base
container_name: snmp-rt1
restart: unless-stopped
hostname: snmp-rt1
network_mode: host
env_file:
- influx_snmp.env
environment:
TELEGRAF_SNMP_AGENT: "192.0.2.1:161"
TELEGRAF_SNMP_AGENT_TYPE: ubiquiti_edgeos
TELEGRAF_SNMP_HOST: rt1
snmp-sw1:
image: robcowart/telegraf-snmp:0.0.1_juniper_ex
container_name: snmp-sw1
restart: unless-stopped
hostname: snmp-sw1
network_mode: host
env_file:
- influx_snmp.env
environment:
TELEGRAF_SNMP_AGENT: "192.0.2.2:161"
TELEGRAF_SNMP_AGENT_TYPE: juniper_ex
TELEGRAF_SNMP_HOST: rt2
snmp-wlan1:
image: robcowart/telegraf-snmp:0.0.1_engenius_wifi
container_name: snmp-wlan1
restart: unless-stopped
hostname: snmp-wlan1
network_mode: host
env_file:
- influx_snmp.env
environment:
TELEGRAF_SNMP_AGENT: "192.0.2.5:161"
TELEGRAF_SNMP_AGENT_TYPE: engenius_wifi
TELEGRAF_SNMP_HOST: wlan1
The external environment variable file influx_snmp.env for global settings:
# The SNMP query timeout.
TELEGRAF_SNMP_TIMEOUT=5s
# polling interval.
TELEGRAF_SNMP_INTERVAL=60s
# SNMPv1/v2c community string
TELEGRAF_SNMP_COMMUNITY=public
# SNMPv3 credentials
TELEGRAF_SNMP_SEC_NAME=username
TELEGRAF_SNMP_AUTH_PROTOCOL=MD5
TELEGRAF_SNMP_AUTH_PASSWORD=changeme
TELEGRAF_SNMP_SEC_LEVEL=authNoPriv
# InfluxDB instance, credentials and DB name.
TELEGRAF_SNMP_INFLUXDB_URL=http://192.168.9.11:8086
TELEGRAF_SNMP_INFLUXDB_USER=admin
TELEGRAF_SNMP_INFLUXDB_PASSWD=changeme
TELEGRAF_SNMP_DATABASE=snmp
You can also easily run InfluxDB, Kapacitor, Chronograf and even Grafana in Docker containers. A
docker-compose.ymlfile to help you get started is available HERE.
This repository includes the configuration and scripts to build containers for each supported device type.
