Install the SNMP Exporter
Description
Now to manually install the SNMP Exporter.
I am going to manually install the latest version of the SNMP Exporter.
To see the latest versions, you can visit,
https://github.com/prometheus/snmp_exporter/releases
Select the file appropriate for your operating system.
I will download snmp_exporter-0.19.0.linux-amd64.tar.gz
wget https://github.com/prometheus/snmp_exporter/releases/download/v0.19.0/snmp_exporter-0.19.0.linux-amd64.tar.gz
Untar it,
tar xzf snmp_exporter-0.19.0.linux-amd64.tar.gz
CD into the new folder that was created and copy the files to the /usr/local/bin/ folder
cd snmp_exporter-0.19.0.linux-amd64
ls -lh
cp ./snmp_exporter /usr/local/bin/snmp_exporter
cp ./snmp.yml /usr/local/bin/snmp.yml
cd /usr/local/bin/
See the snmp_exporter help
./snmp_exporter -h
Create a new user (if it doesn't already exist)
sudo useradd --system prometheus
Create a new file called snmp-exporter.service
sudo nano /etc/systemd/system/snmp-exporter.service
Add the script and save
[Unit]
Description=Prometheus SNMP Exporter Service
After=network.target
[Service]
Type=simple
User=prometheus
ExecStart=/usr/local/bin/snmp_exporter --config.file="/usr/local/bin/snmp.yml"
[Install]
WantedBy=multi-user.target
Now start and check the service is running.
systemctl daemon-reload
sudo service snmp-exporter start
sudo service snmp-exporter status
Visit in the browser http://[ip or domain]:9116
Now to add the configuration to the prometheus.yml
sudo nano /etc/prometheus/prometheus.yml
Add the following to the end of the existing YML.
- job_name: snmp
metrics_path: /snmp
params:
module: [if_mib]
static_configs:
- targets:
- 127.0.0.1
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: 127.0.0.1:9116 # URL as shown on the UI
Save and check changes to the config are syntactically correct
promtool check config /etc/prometheus/prometheus.yml
And if OK, then restart the Prometheus service.
sudo service prometheus restart
sudo service prometheus status
