ta-postgres Authentication issue

marcoscala — Tue, 09 Aug 2016 15:53:54 GMT

hi!
I'm trying to monitor a Postgres DB using the ta-postgres TA.

I have an authentication issue: the DBA created a user "splunk" and provided me with the password. I have tried the following configuration options in ta-postgres/local/postgrestats.conf:

Option 1.
[default]
defaultdb =
host = host.domain
port = 5432
user = splunk
password = {md5}splunk83fef3dd6477

Option 2.
[default]
defaultdb =
host = host.domain
port = 5432
user = splunk
password = md5bacb6374010b3f7af42dc7a670da9db4
(md5 coded password from the postgres db)

In both cases I get the following error message on the DB in the "postgresql*.log :
UTC FATAL: password authentication failed for user "splunk"

Thanks for support!!!

Actually, digging in the code of the ta, we found that the bin/postgrestats.py uses the connect method from psycopg2:

psycopg2.connect(connect_string(defaultdb, dbhost, dbport, dbuser, dbpassword))

Cheching online it looks like the dbpassword must be passed NOT MD5ed...

so the working final config for me was:

password = splunk83fef3dd6477

with the password in clear!!!

Hope this will help!!!
