Fortio Introduction

Fortio is a load testing tool that consists of:

  • A server
  • A client
  • A GUI
  • A load testing library

Fortio runs a specified number of queries per second (qps), records a histogram of execution time and calculates percentiles. It can run for a set duration, for a fixed number of calls, or until interrupted.

Fortio Server

The server command starts the grpc, http, and https redirector servers:

$ fortio server &
Fortio 0.8.0 grpc 'ping' server listening on [::]:8079
Fortio 0.8.0 https redirector server listening on [::]:8081
Fortio 0.8.0 echo server listening on [::]:8080
UI started - visit:
http://localhost:8080/fortio/   (or any host/ip reachable on this server)
21:45:23 I fortio_main.go:195> All fortio 0.8.0 buildinfo go1.10 servers started!

Docker example (with debug logging):

$ docker run --name fortio_server -p 8080:8080 -p 8079:8079 istio/fortio server -loglevel debug &

The /fortio http endpoint serves the GUI and can be viewed from http://localhost:8080/fortio/. The http echo server echos back data that it receives and is served from the /echo endpoint. For example:

$ curl -d foo http://localhost:8080/echo/
foo

The 0.8 release added a TCP Proxy server. The server listens on a specified address:port and proxies TCP traffic to a remote address:port using the -P flag:

# Remove the running fortio_server Docker container:
$ docker rm -f fortio_server

# Start Fortio server using -P to enable the TCP proxy.
# Note: Change "35.230.102.204:80" to your destination address:port
$ docker run --name fortio_server -p 8080:8080 -p 8079:8079 istio/fortio server -loglevel debug -P "$FORTIO_IP:8089 35.230.102.204:80" &

15:59:09 D network.go:80> Host already an IP, will go to 35.230.102.204

Then curl the Fortio proxy address:port:

# Get the IP of the Fortio server Docker container:
FORTIO_IP=$(docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' fortio_server)

$ docker run istio/fortio.fcurl:latest -loglevel debug -L http://$FORTIO_IP:8089/echo/

Fortio Client

Fortio provides a grpc and an http client that is used to generate loads and collect statistics.

load is the http client:

$ docker run istio/fortio:latest load http://$FORTIO_IP:8080/echo/
Fortio 0.3.6 running at 8 queries per second, 8->8 procs, for 5s: http://www.google.com

A fcurl minimal curl client binary was added in the latest (v0.8) release. The compressed image size is roughly 2MB. This client is the same as fortio curl

$ docker run istio/fortio.fcurl:latest -loglevel debug -L http://$FORTIO_IP:8080/echo/

Fortio Library

forexample is an example Fortio library implementation. Results of test run.

Istio Perf Cluster:

istio/tools/setup_perf_cluster.sh deploys a GKE cluster, an Istio service mesh and a GCE VM. The script then runs Fortio on the VM, 2 pods within the cluster (non-Istio) and 2 pods within the Istio mesh.

Download and untar the Istio release (for Mac):

$ RELEASE=0.6
$ wget https://github.com/istio/istio/releases/download/$RELEASE/istio-$RELEASE.0-osx.tar.gz
$ tar -xvf istio-$RELEASE.0-osx.tar.gz

Copy the istioctl client binary to your $PATH:

$ cp istio-$RELEASE.0/bin/istioctl /usr/local/bin/istioctl

Clone the Istio repo, which contains the perf cluster setup script:

$ git clone -b release-$RELEASE https://github.com/istio/istio.git

Source the script:

$ source istio/tools/setup_perf_cluster.sh

Run the setup_all function:

$ setup_all
Obtaining latest ubuntu xenial image name... (takes a few seconds)...
Creating VM_NAME=fortio-vm using VM_IMAGE=https://www.googleapis.com/compute/v1/projects/ubuntu-os-cloud/global/images/ubuntu-1604-xenial-v20180306
<SNIP>

Run the get_ips function:

$ get_ips
+++ VM Ip is 35.230.102.204 - visit http://35.230.102.204/fortio/
+++ In k8s fortio external ip: http://35.230.62.254:8080/fortio/
+++ In k8s non istio ingress: http://35.227.220.111/fortio/
+++ In k8s istio ingress: http://35.230.50.21/fortio1/fortio/ and fortio2

Test access to the IPs with curl or your web browser.
