如何在Go中获取Riak KV群集和节点状态数据

Question

I'm trying to monitor Riak-KV from Go program. Riak has a client for go named 'riak-go-client', But it doesn't have any api to get Riak performance/Status data. Is there any way to get it ?

Answer 1

The best way to get Riak performance/status/metrics might be via its stats HTTP API. It works with any language or even using curl. As long as you know how to connect via HTTP and parse JSON, you should be able to use it.

Using the API can be as simple as running:

curl -v http://127.0.0.1:8098/stats -H "Accept: application/json"

It gives you a lot of useful information like allocated and used memory, get/put statistics, CPU utilization, ring status, etc.

Riak Explorer exposes an even more powerful API that allows not only to monitor, but also manage Riak clusters. You have to install the tool separately though.
