Speed up Instgo compilation with caching - Application Real-Time Monitoring Service

Instgo recompiles instrumentation code on every build, even when source files have not changed. Enable the built-in build cache to skip redundant compilation and reduce build time by more than 50%.

Prerequisites

Before you begin, make sure that you have:

Instgo 1.4.6 or later. For download details, see Instgo tool overview
A local machine or Elastic Compute Service (ECS) instance. You cannot compile in a container

Enable the build cache

Step 1: Download Instgo

Download the Instgo binary for your runtime environment. The following example downloads the Linux AMD64 binary. For other platforms, see Instgo tool overview.

wget "http://arms-apm-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/instgo/instgo-linux-amd64" -O instgo

Step 2: Make the binary executable

chmod +x instgo

Step 3: Set the cache directory

Specify a directory where Instgo stores compiled artifacts.

# Store cached artifacts in /tmp/go-cache
./instgo set --goCache=/tmp/go-cache

Step 4: Build your Go application

Run the first build. Instgo populates the cache during this build.

./instgo go build main.go

All subsequent builds on the same machine automatically reuse the cached artifacts, reducing total compilation time by more than 50%.

Verify the cache

After the first build completes, run a second build and compare the build times. The second build should finish noticeably faster because Instgo reuses the cached artifacts.
