Learn how to manually install a Wavefront proxy and Telegraf agent.

Most Tanzu Observability by Wavefront customers use an automated proxy install:

  • Option 1: Install the Wavefront proxy and the Telegraf agent when the set up an integration.
  • Option 2: Perform a scripted installation of the Wavefront proxy and Telegraf agent.

In some environments, it’s necessary to perform a manual installation instead. This page gives some guidance. You can perform additional customization using proxy configuration properties.

Proxy Install - Full Network Access

Follow these steps to install a proxy on a host with full network access (incoming and outgoing connections).


  • Networking: Test connectivity between the target proxy host and your Wavefront service.

  • JRE: The Wavefront proxy is a Java jar file and requires a JRE - for example, openjdk11. See the requirements in the Wavefront Proxy README file.

Step 1: Download the Proxy

If your system accepts incoming traffic, you can download the proxy file as follows:

  1. Download the proxy .rpm or .deb file from packagecloud.io/wavefront/proxy.
  2. Run sudo rpm -U <name_of_file.rpm> or sudo dpkg -i <name_of_file.deb>.

Step 2: Determine Proxy Settings

Before you can customize the proxy configuration, you have to find the values for your environment. You need the following information to customize the settings.

server URL of the Wavefront instance you log in to. https://try.wavefront.com/api/
token API token. See Note above. xxxxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxxxxx
hostname Name of the host the proxy will run on. The hostname is not used to tag your data; rather, it’s used to tag data internal to the proxy, such as JVM statistics, per-proxy point rates, and so on. Alphanumeric and periods are allowed. cust42ProxyHost
enable graphite Whether to enable the Graphite format. See the Graphite integration for details on Graphite configuration. cust42ProxyHost
tlsPorts Comma-separated list of ports to be used for incoming HTTPS connections.
privateKeyPath Path to PKCS#8 private key file in PEM format. Incoming HTTPS connections access this private key.
privateCertPath Path to X.509 certificate chain file in PEM format. Incoming HTTPS connections access this certificate.

Step 3: Make Configuration Changes

You can make configuration changes by editing the config file or by running a script.

Option 1: Editing the Config File

If you want to edit the configuration file manually:

  1. Find, uncomment and modify the configuration:
    Change to MakeConfig Parameters
    Change target. server= hostname= token=
    Use Graphite If you want to use Graphite, specify the Graphite configuration section starting with: graphitePorts=2003
  2. Start the Wavefront proxy service:
    sudo service wavefront-proxy start

Option 2: Running the autoconf Script

You can specify the settings by running bin/autoconf-wavefront-proxy.sh.

After the interactive configuration is complete:

  • The Wavefront proxy configuration at /etc/wavefront/wavefront-proxy/wavefront.conf is updated with the input that you provided.
  • The wavefront-proxy service is started.

Proxy Install – Limited Network Access

In some cases, you might need to run the proxy on a host with limited network access.


  • Networking: The minimum requirement is an outbound HTTPS connection to the Wavefront service, so the proxy can send metrics to the Wavefront service. For metrics, by default the proxy uses port 2878. You can change this port and you can configure separate proxy ports for histograms and traces.

    You can use an HTTP proxy for the connection.

  • JRE: The Wavefront proxy is a Java jar file and requires a JRE - for example, openjdk11. See the requirements in the Wavefront Proxy README file.

Installation and Configuration

Installation and configuration is similar to environments with full network access but might require additional work.

  1. Make sure all prerequisites are met, including an open outgoing HTTPS connection to the Wavefront service and JRE.
  2. Install the .rpm or .deb file.
  3. Update the settings, either by editing the configuration file or by running the autoconf script, as explained above.
  4. You may need to update the Wavefront proxy control file /etc/init.d/wavefront.proxy to the following settings:
   desc=${DESC:-Wavefront Proxy}
   proxy_jre_dir="$proxy_dir/proxy-jre"                  <-- set to location of currently installed JRE
   export JAVA_HOME=${PROXY_JAVA_HOME:-$proxy_jre_dir}   <-- set to location of currently installed JRE

Proxy Custom Install with Incoming TLS/SSL

By default Wavefront proxy can accept incoming TCP and HTTP requests on the port specified by pushListenerPorts. You can also configure the proxy to accept only connections with a certificate and key.

In that case:

  1. Specify that you want to open the port with the pushListenerPorts config parameter.
  2. Specify the tlsPorts, privateKeyPath, and privateCertPath parameters.

The following parameters support TLS/SS. You can specify those parameters in the configuration file or by running bin/autoconf-wavefront-proxy.sh, as discussed above.

tlsPorts Comma-separated list of ports to be used for incoming TLS/SSL connections.
privateKeyPath Path to PKCS#8 private key file in PEM format. Incoming TLS/SSL connections access this private key.
privateCertPath Path to X.509 certificate chain file in PEM format. Incoming TLS/SSL connections access this certificate.

Testing Proxy Host Connectivity

You can test connectivity from the proxy host to the Wavefront instance using curl.

Run this test before installing the proxy, and again after installing and configuring the proxy.

  1. Find the values for server and token:
    1. Click Integrations on the toolbar.
    2. Select Linux Host and click the Setup tab.
  2. Run the following command:
    curl -v https://your-server.wavefront.com/api/daemon/test?token=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Here is an example of the expected return when you use the -v parameter (without -v only HTTP(S) errors are reported):

* About to connect() to myhost.wavefront.com port 443 (#0)
*   Trying NN.NN.NNN.NNN...
* Connected to myhost.wavefront.com (NN.NN.NNN.NNN) port 443 (#0)

< X-Upstream: 10.15.N.NNN>:NNNNN
< X-Wavefront-Cluster: /services-<services>
< X-Frame-Options: SAMEORIGIN
* Connection #0 to host myhost.wavefront.com left intact

Testing Your Installation

After you have started the proxy you just configured, you can verify its status from the UI or with curl commands.

Testing From the UI

To check your proxy from the UI:

  1. Log in to your Wavefront instance from a browser.
  2. From the toolbar, select Browse > Proxies to view a list of all proxies. If the list is long, type the proxy name as defined in hostname= in wavefront.conf to located the proxy by name.

Testing Using curl

You can test your proxy using curl. Documentation for the following curl commands can be found directly on your Wavefront instance at https://<your-server.wavefront.com>/api-docs/ui/#!/Proxy/getAllProxy.

You can run the commands directly from the API documentation. This is less error prone than copy/paste of the token.

For this task, you first you get the list of proxies for your Wavefront service, then you display information for just the proxy you installed.

Step 1: Get the list of proxies for your Wavefront instance:

curl -X GET --header "Accept: application/json" --header "Authorization: Bearer xxxxxxxxx-<your api token>-xxxxxxxxxxxx" "https://<yourserver.wavefront.com/api/v2/proxy?offset=0&limit=100"

This command returns a JSON formated list of all proxies. Step 2: Get the proxy ID. You can search the output using the proxy name configured in wavefront.conf, or find the proxy ID in the UI.

Step 3: Return information for only this proxy:

curl -X GET --header "Accept: application/json" --header "Authorization: Bearer xxxxxxxxx-<your api token>-xxxxxxxxxxxx" "https://<yourserver>.wavefront.com/api/v2/proxy/443e5771-67c8-40fc-a0e2-674675d1e0a6"

Sample output for single proxy:

    "status": {
        "result": "OK",
        "message": "",
        "code": 200
    "response": {
        "customerStatus": "ACTIVE",
        "version": "4.34",
        "status": "ACTIVE",
        "customerId": "mike",
        "inTrash": false,
        "hostname": "mikeKubeH",
        "id": "443e5771-67c8-40fc-a0e2-674675d1e0a6",
        "lastCheckInTime": 1547069052859,
        "timeDrift": -728,
        "bytesLeftForBuffer": 7624290304,
        "bytesPerMinuteForBuffer": 31817,
        "localQueueSize": 0,
        "sshAgent": false,
        "ephemeral": false,
        "deleted": false,
        "statusCause": "",
        "name": "Proxy on mikeKubeH"

Configure Wavefront Proxy with an HTTP/HTTPS Proxy

The Wavefront proxy initiates an HTTPS connection to the Wavefront service. The connection is made over the default HTTPS port 443.

Instead of sending traffic directly, you can send traffic from the Wavefront proxy to an HTTP or HTTPS proxy, which forwards to the Wavefront service. You set the connection parameters in the wavefront.conf file (/etc/wavefront/wavefront-proxy/wavefront.conf by default). See

Modify wavefront.conf to Use an HTTP/HTTPS Proxy

By default, the HTTP/HTTPS proxy section is commented out. Uncomment the section in wavefront.conf if you want to use an HTTP/HTTPS proxy, and specify the following information:

## The following settings are used to connect to a Wavefront instance through a HTTP proxy:
#proxyHost=<location of the HTTP/HTTPS proxy>
#proxyPort=<port for connecting with the HTTP/HTTPS proxy. Default is 8080>
## Optional: if http/https proxy supports username/password authentication

Set up Wavefront Proxy to Use the CAcerts of the HTTPS Proxy

An HTTPS proxy requires that its clients use one or more site-specific CA-signed certificate. Those certificates (in PEM format) must be imported into the trust store of the Wavefront proxy.

  • The HTTPS proxy includes the CA signed certificates.
  • The Wavefront proxy must have those certificates (PEM files) as well.

Use keytool to import the CA certificates into the Wavefront proxy

keytool -noprompt -cacerts -importcert -storepass changeit -file ${<filename>} -alias ${alias}

Here, filename is the name of the PEM file. If there’s more than one PEM file, run the command again.

Installing Telegraf Manually

If the system has network access, follow our instructions for installing Telegraf

We include instructions for using .deb, .rpm, node, python, and gem for installing from the network.

If you’re in an environment with restricted network access:

  1. Download the appropriate Telegraf package from InfluxData and install as directed.
  2. Create a file called 10-wavefront.conf in /etc/telegraf/telegraf.d and enter the following snippet:
      port = 2878
      metric_separator = "."
      source_override = ["hostname", "agent_host", "node_host"]
      convert_paths = true
  3. Start the Telegraf agent:
   sudo service telegraf start

How to Chain Proxies

Sometimes, the output from one Wavefront proxy needs to be sent to another Wavefront proxy (proxy chaining).

Common Use Cases for Chained Proxies

Common use cases include:

  • Restrictions on outbound connections: In environments where no direct outbound connections to the Wavefront service are possible, you can use a Wavefront proxy that has outbound access to act as a relay and forward data received on its endpoint to the Wavefront service.
  • Log data filtering: If you use a proxy to parse log data, you might need to perform filtering or tagging with proxy preprocessor rules. One proxy in a chain can have the job of altering or dropping certain strings before data is sent to the Wavefront service.
  • Preprocessor rule consolidation: Proxy chaining can consolidate preprocessing rules to a central proxy. For example, proxies running in containers on a Kubernetes cluster could relay metrics to the chained proxy which has all required defined preprocessor rules.

Set Up the Configuration Files for Chaining

Let’s set up proxy chaining. Proxy A sends data to the relay proxy (Proxy B). Proxy B then sends data to the Wavefront service. Follow these steps:

  1. On the proxy which will act as the relay (Proxy B) open the proxy configuration file (wavefront.conf) for edit. See Proxy File Paths for the default location.
  2. Uncomment the pushRelayListenerPorts line so the proxy will listen for any relay messages.
    ## This setting is a comma-separated list of ports. (Default: none)
  3. On the proxy that will send its metrics to the relay proxy (Proxy A), open the proxy configuration file wavefront.conf for editing.

  4. Change the server address to the address of relay (Proxy B). Here’s an example:
      # The server should be either the primary Wavefront cloud server, or your custom VPC address.
      # This will be provided to you by Wavefront.

    The authentication token that is specified in the wavefront.conf of the relay proxy (Proxy B) will be used to send the metrics to the Wavefront instances. An authentication token for Proxy A is not needed.

  5. After making the changes, restart both proxies and examine the wavefront.log file from the relay proxy (Proxy B). Look for points that are delivered on the relay listener port, as in the following example:

      2021-02-04 17:11:50,201 INFO [AbstractReportableEntityHandler:printStats] [2978] Points received rate: 4 pps (1 min), 4 pps (5 min), 0 pps (current).
      2021-02-04 17:11:50,201 INFO [AbstractReportableEntityHandler:printStats] [2978] Points delivered rate: 4 pps (1 min), 4 pps (5 min)
      2021-02-04 17:12:00,200 INFO [AbstractReportableEntityHandler:printStats] [2978] Points received rate: 4 pps (1 min), 4 pps (5 min), 0 pps (current).
      2021-02-04 17:12:00,201 INFO [AbstractReportableEntityHandler:printStats] [2978] Points delivered rate: 4 pps (1 min), 4 pps (5 min)

Test Proxy Host Connectivity

You can test connectivity from the originating proxy to the relay proxy. Pick one option:

  • Use curl
  • Send the points locally and verify that they are delivered by querying the metric in the GUI

In both scenarios the relay proxy uses its own token to authenticate. A separate token for the proxy that’s sending the metrics is not needed.

Test Connectivity Using curl

Run the following command from the proxy that is sending metrics to the relay proxy (http://192.168.xxx.xxx:2978 is the address/port of the relay proxy.)

curl -v 'http://192.168.xxx.xxx:2978' -X POST -d "test.metric 100 source=test.source"

Sample output:

* About to connect() to 192.168.xxx.xxx port 2978 (#0)
* Trying 192.168.xxx.xxx...
* Connected to 192.168.xxx.xxx (192.168.xxx.xxx) port 2978 (#0)
> POST / HTTP/1.1
> User-Agent: curl/7.29.0
> Host: 192.168.xxx.xxx:2978
> Accept: */*
> Content-Length: 35
> Content-Type: application/x-www-form-urlencoded
* upload completely sent off: 35 out of 35 bytes
< HTTP/1.1 204 No Content
< content-type: text/plain
< connection: keep-alive

Test Connectivity by Sending Points

To send points directly:

  1. Run the following command locally on the proxy that sending metrics to the relay proxy.
    `echo 'test.metric 300 source=test.source' | nc localhost 2878`
  2. Verify that you can query the metric in the GUI.
