Prometheus exporter for RethinkDB cluster and table metrics. Supports RethinkDB 2.x

rethinkdb_exporter's Issues

grafana detects no data

able to connect with rethinkdb successfully.
however grafana keeps updating the query at localhost:9123 and not capable to get the data under localhost:9123/metrics

for example, trying to get
rethinkdb_server_client_connections{server="db01"}

the response from query is the webpage at localhost:9123

how to resolve this? any ideas?

Passing flags to docker

Hey so I am having a new issue, first time using Docker and I am unable to find how do I pass flags to my Docker so it successfully connect to the database?

Support for mTLS connection to rethink (not user / pass)

As far as I can see this isn't currently supported? Happy to work on a PR if that's something of interest?

Explicit Project License?

Should this project have an explicit license associated with it? Without an explicit license, the implicit license prohibits users from distributing the code (which ultra-bureaucratic $DAYJOB is interpreting as "cannot install onto servers").

scrape err: gorethink: dial tcp [::1]:28015: connectex: No connection could be made because the target machine actively refused it.

Follow the git instructions and everything looks okay.

1. git clone the repo
2. import the dashboard panel json in grafana
3. add the data source using http://localhost:9123
4. after go build, when running "rethinkdb_exporter db.table-stats"
   It gives the following error message and no data shows in the grafana dashboard. When checking the localhost:9123/metrics the table stats refreshed and looked okay. I am not sure how to fix this issue. any ideas? Thanks in advance. This example is pretty cool.
   
   
   

Grafana displays nothing

Hey, I did all the steps to install and added grafana dahsboard and nothing works.

I can acceed to localhost:9123, everything is displayed and works but I can not acceed to it on grafana, any solution ?

Thanks

rethinkdb_exporter image on Docker Hub

Perhaps related to #8 - for my use case (deploying to a k8s cluster via a Helm chart) it would be valuable to have a standard Docker image for rethinkdb_exporter published on Docker Hub.

If you can create a namespace/repository for it I'll be happy to contribute the plumbing for releases.

Make docker image build part of the CircleCI pipeline

Should do the same as here: https://github.com/oliver006/redis_exporter/blob/master/circle.yml#L49

err: gorethink: Wrong password

I'm trying to deploy rethinkdb_exporter to monitor a cluster created with the Helm stable/rethinkdb chart. I've got rethinkdb_exporter installed and running, but whenever it attempts to connect to my configured node(s) it logs the error scrape err: gorethink: Wrong password.

I've tried setting the --db.auth flag to my admin password, and blank, but it makes no difference.

I know the README.md says "Supports RethinkDB 2.x" but is it definitely known to work with 2.3.x? If so, what's the right way to extract from my cluster the value for --db.auth?

Cannot build image using rethinkdb_exporter:v.0.5.0

While using rethinkdb_exporter:v0.5.0 to build new image , it throws error "/bin/sh not found in $PATH" on every command specified in RUN.

Please don't count my rows

res, err := r.DB(s.DB).Table(s.Table).Count().Run(sess)

Counting table rows is a horrible idea, as it's currently not very optimized in RethinkDB and can take several seconds for larger tables. (1s for 4M rows on 3 nodes - and that's all only since we have it all cached in memory.)

This should be optional, and turned off by default.

do you have an example of connecting to aws rethinkdb?

does the command take a .json file for parameters db.user and db.pass, etc?
such like,

rethinkdb-exporter rethinkdb_config.json

thanks.

Compile error with alpine 3.2

Hi,
I got the same error reported in the following link during building:

bosun-monitor/bosun#1360

Looks like you need go 1.5 to compile it properly but that's not available for alpine 3.2. Trying to use alpine:latest won't work due to a regression in go 1.7.

I solved by using alpine 3.3
