couchbase-exporter

A prometheus couchbase exporter!

All others I found seem to be abandoned and/or very incomplete. This is an attempt to have all metrics exported, including task-related metrics!

Goal

Innitially, have the same metrics as our old exporter, to facilitate the migration.

Once that's done, we can better document all metrics, eventually improve their naming (like adding _total, _seconds, _byte prefixes), and finally, provide example alerting rules and grafana dashboards, so it's easier to proper monitor a couchbase cluster.

It's worth saying that we will only support Couchbase 5+ for now.

Installation

Building from source

This requires the user to have go installed on their system, preferably version1.13 and onwards.

1. Run git clone https://github.com/totvslabs/couchbase-exporter.git.
2. Change directory by running cd couchbase-exporter.
3. Create a go executable by running go build -o couchbase-exporter main.go. You might have to prefix sudo if you encounter permission issues.
4. Start the exporter using ./couchbase-exporter followed by specific flags and their values.

Using the Releases

1. Pick from the couchbase-exporter releases available here depending on whether you're a macOS or Linux user.
2. Download the release binary and extract it.
3. The exporter is now ready to be used!

Usage

$ export COUCHBASE_PASSWORD=secret
$ couchbase-exporter --couchbase.username adm

check couchbase-exporter --help for more options!
