Prometheus

Running a Prometheus monitoring service is the easiest way to ingest and record etcd’s metrics.

First, install Prometheus:

 
 
 
  
PROMETHEUS_VERSION="1.3.1"
 
  
wget https://github.com/prometheus/prometheus/releases/download/v$PROMETHEUS_VERSION/prometheus-$PROMETHEUS_VERSION.linux-amd64.tar.gz -O /tmp/prometheus-$PROMETHEUS_VERSION.linux-amd64.tar.gz
 
  
tar -xvzf /tmp/prometheus-$PROMETHEUS_VERSION.linux-amd64.tar.gz --directory /tmp/ --strip-components=1
 
  
/tmp/prometheus -version
 
 
 
 

Set Prometheus’s scraper to target the etcd cluster endpoints:

 
 
 
  
cat > /tmp/test-etcd.yaml <
 
  
global:
 
  
scrape_interval: 10s
 
  
scrape_configs:
 
  
- job_name: test-etcd
 
  
static_configs:
 
  
- targets: ['10.240.0.32:2379','10.240.0.33:2379','10.240.0.34:2379']
 
  
EOF
 
  
cat /tmp/test-etcd.yaml
 
 
 
 

Set up the Prometheus handler:

 
 
 
  
nohup /tmp/prometheus \
 
  
-config.file /tmp/test-etcd.yaml \
 
  
-web.listen-address ":9090" \
 
  
-storage.local.path "test-etcd.data" >> /tmp/test-etcd.log 2>&1 &
 
 
 
 

Now Prometheus will scrape etcd metrics every 10 seconds.

Grafana

Grafana has built-in Prometheus support; just add a Prometheus data source:

 
 
 
  
Name: test-etcd
 
  
Type: Prometheus
 
  
Url: http://localhost:9090
 
  
Access: proxy
 
 
 
 

Then import the default etcd dashboard template and customize. For instance, if Prometheus data source name is my-etcd, the datasource field values in JSON also need to be my-etcd.
