inspect

inspect is a collection of operating system/application monitoring analysis libraries and utilities with an emphasis on problem detection.

Installation

1. get go
2. go get -u -v github.com/square/inspect/...

The above commands should install three binaries in your original $GOPATH/bin directory.

1. inspect
2. inspect-mysql (work in progress)
3. inspect-postgres (work in progress)

Please see subdirectories for more detailed documentation

Glossary

• cmd - Directory for command line programs based on the below libraries

• os - Operating system metric measurement libraries used by inspect.
• mysql - MySQL metric reporting libraries.
• postgres - Postgres metric reporting libraries.
• metrics/metricscheck - Simple metrics libraries for golang.

Development

Development setup is a bit tricky given interaction of godep/gopath:

• Create a fork
• Setup golang workspace and set GOPATH Reference
  • export GOPATH=$HOME/godev # example
  • mkdir -p $GOPATH/{src,bin,pkg}
• Setup project
  • mkdir -p $GOPATH/src/github.com/square
  • cd $GOPATH/src/github.com/square
  • git clone git@github.com:CHANGE-ME/inspect.git # change path to your fork
  • cd inspect
• Setup a reference to upstream to sync changes with upstream easily etc
  • git remote add upstream github.com/square/inspect.git

[s@pain inspect (master)]$ git remote -v
origin	git@github.com:syamp/inspect.git (fetch)
origin	git@github.com:syamp/inspect.git (push)
upstream	github.com/square/inspect.git (fetch)
upstream	github.com/square/inspect.git (push)

• We use godep for vendoring and dependency management. We rewrite import paths. If you are adding a new dependency or updating one, please run

  1. godep save -r

• Please format, test and lint before submitting PRs

  1. go fmt ./...
  2. go test ./...
  3. $GOPATH/bin/golint ./...

Todo

• metriccheck uses some darkmagic and uses golang/x/tools APIs which tend to break API compat often. Need to fix it.
