Prometheus is an open-source monitoring and alerting toolkit. This integration installs and configures Telegraf to collect Prometheus format metrics. Telegraf is a light-weight server process capable of collecting, processing, aggregating, and sending metrics to a Wavefront proxy.
To see a list of the metrics for this integration, select the integration from https://github.com/influxdata/telegraf/tree/master/plugins/inputs.
Step 1. Install the Telegraf Agent
This integration uses the Prometheus input plugin for Telegraf. If you’ve already installed Telegraf on your server(s), you can skip to Step 2.
Log in to your Wavefront instance and follow the instructions in the Setup tab to install Telegraf and a Wavefront proxy in your environment. If a proxy is already running in your environment, you can select that proxy and the Telegraf install command connects with that proxy. Sign up for a free trial to check it out!
Step 2. Configure Prometheus Input Plugin
Create a file called
/etc/telegraf/telegraf.d and enter the following snippet:
# Read metrics from one or many prometheus clients [[inputs.prometheus]] ## An array of urls to scrape metrics from. urls = ["http://localhost:9100/metrics"] ## Use bearer token for authorization # bearer_token = /path/to/bearer/token ## Specify timeout duration for slower prometheus clients (default is 3s) # response_timeout = "3s" ## Optional SSL Config # ssl_ca = /path/to/cafile # ssl_cert = /path/to/certfile # ssl_key = /path/to/keyfile ## Use SSL but skip chain & host verification # insecure_skip_verify = false
Replace the urls with your server address.
urls = ["http://[your_server_address]/metrics"]
Step 3. Restart Telegraf
sudo service telegraf restart to restart your agent.
