If you try to run prometheus_couchbase_exporter inside the docker image python:3.6.4-alpine the reduce method used on the _dot_get method is not defined. You need to include the import

from functools import reduce

Where can I submit questions to you guys pertaining to this. The only issue I am having is I am not familiar with this exporter.

Thanks,

hi, i got this error
text format parsing error in line 28: invalid metric name in comment

abouth this line:

HELP couchbase_bucket_stats_ep_dcp_views+2i_total_backlog_size ep_dcp_views+2i_total_backlog_size

the exporter itterates all buckets but adds only metrics from the last one

tried to find a way to fix it but i couldn't

thanks

is this project still being maintained?

I'm asking because I kind of use it so if it's not being maintained anymore I'll fork it or do something else.. hehe

Thanks for the project, btw :)

hi,

in case anyone else stumbles upon same issue like me, the instructions suggest to use:

$ prometheus-couchbase-exporter -c <couchbase host:port> -p <port to listen>

correct way is to use:

$ prometheus-couchbase-exporter -c http://<couchbase host:port> -p <port to listen>

sample output from my env:

[root@optima-ansible ~]# prometheus-couchbase-exporter -c 192.168.16.205:8091
Failed to establish a new connection. Is 192.168.16.205:8091 correct?
[root@optima-ansible ~]# prometheus-couchbase-exporter -c http://192.168.16.205:8091
Response Status (401): 
[root@optima-ansible ~]# 

i believe readme.rst should be updated.

thanks!

The exporter should fall in line with other standard Prometheus exporters by listening on /metrics.
