opentsdb prometheus exporter metrics monitoring

opentsdb_exporter's Introduction

OpenTSDB Exporter

A daemon that takes the URL of an OpenTSDB server and exposes Prometheus metrics based on data scraped from OpenTSDB's stats API.

See OpenTSDB's API documentation on the stats endpoint.

Tested on OpenTSDB 2.3.

Prerequisites

To use the OpenTSDB exporter, you'll need:

an OpenTSDB cluster

To build, you'll need:

Make
Go 1.8 or above
a working GOPATH

Limitations

The metrics generated are translated one-to-one from the metrics exposed on the stats endpoint, so do not follow the Prometheus metric naming conventions. This is primarily to keep the code simple.

How to run

go get -u github.com/cloudflare/opentsdb_exporter
cd $GOPATH/src/github.com/cloudflare/opentsdb_exporter
make
./opentsdb_exporter

How to run the tests

make tests

Make metrics scrappable by Prometheus

It is not possible to scrape this exporter with Prometheus. The following error is thrown by Prom

"INVALID" is not a valid start token

My suspicion is this is because there are no labels in a few of the metrics which are exposed.

Normalise metric names and add help info

OpenTSDB's metrics are described here:
http://opentsdb.net/docs/build/html/user_guide/stats.html

We should look specifically for metrics matching these descriptions, then set the metric type and help text accordingly.

We can also make the metric names more consistent with Prometheus' conventions:
https://prometheus.io/docs/practices/naming/

How to add metrics in the '/metrics' url

I follow the steps and start the exporter with './opentsdb_exporter'. But only go metrics list in the '/metrics' url
How can I add opentsdb metrics in the '/metrics' url?

Cannot find module providing prometheus log package
