sys.json

Exposes server performance stats as an API.

It works, but it's a work in progress. Things are subject to change without notice, so please use caution if you decide to use this in production. Assume there are bugs.

Why?

There are plenty of other tools out there that can give you stats. There's SNMP, dozens of monitoring solutions and stat collection agents, and more. So why this?

Many of these solutions are complicated to setup and get data from. The goal of sys.json is to provide a simple API for querying a server about the stats you're interested in. No more, no less. What you do with that data is up to you.

Running It

go get
go build
./sysjson --listen 127.0.0.1:5374

Important: Note the bind to the loopback interface and not 0.0.0.0. This is not a service you'll want to expose to the Internet.

sys.json
Exposes server performance stats as an API.
It works, but it's a work in progress. Things are subject to change without notice, so please use
caution if you decide to use this in production. Assume there are bugs.
Why?
There are plenty of other tools out there that can give you stats. There's SNMP, dozens of monitoring
solutions and stat collection agents, and more. So why this?
Many of these solutions are complicated to setup and get data from. The goal of sys.json is to
provide a simple API for querying a server about the stats you're interested in. No more, no less.
What you do with that data is up to you.
Running It
go get
go build
./sysjson --listen 127.0.0.1:5374
Important: Note the bind to the loopback interface and not 0.0.0.0. This is not a service you'll want to expose to the Internet.
