Cbstats can't use in couchbase server 5.0

Couchbase Server
1

Hi All,

I was used cbstats for collecting metrics on couchbase 4.6.3 version.

but cbstats can not use couchbase 5.0 version because error occurred.
i was use two command becuase 4.6.3 type and 5.0 type is differ.
error message is follow:
/opt/couchbase/bin/cbstats localhost:11210 -j -b <bucket_name> -p<bucket_password> all
/opt/couchbase/bin/cbstats localhost:11210 -j -b <bucket_name> -u<user_name> -p<user_password> all

why did occur this error message? also, how do i use cbstats cli? please let me know.

Thanks,
Eddie.

Sounds like the user you are trying to use doesn’t have access to the specified bucket.

Can you try with a different user - say the admin user - and see if that works?

@drigby i tried another user that admin user and new user.
but, i can’t use cbstats. Is there another issue in cbstats?

Works for me here on macOS:

/Applications/Couchbase\ Server.app/Contents/Resources/couchbase-core/bin/cbstats \
    localhost:11210 -j -u stats -p password -b default all
{
    "accepting_conns": 1,
    "auth_cmds": 0,
    "auth_errors": 0,
    "bytes": 4336048,
...

The user you are specifying needs to have bucket admin access (IIRC) to read stats - check what roles your user has.

i know admin access role and i use admin account for viewing cbstats.
but couchbase cli occurred Error Message.

only query node has occurred this message, data node not occurred.

cbstats only returns statistics from Data nodes, there’s no Data buckets on query-only nodes. This is expected behaviour.
