Hi there

I was triying to connect to a DB MSSQL from metricbeat, but I have 2 errors.

 ![imagen](https://us1.discourse-cdn.com/elastic/original/3X/e/5/e51f1d156753e4aae623e457b86095c844389f4d.png)

Can you help me?

Greetings

Hi @Jose_Campos -

- Is this a new problem?
- Does this error happen when you start Metricbeat? or, is this an intermittent issue?
- Is Metricbeat running in the same host as your database?
- Which version of Metricbeat are you using?
- Provide the [debug logs](https://www.elastic.co/guide/en/beats/metricbeat/current/enable-metricbeat-debugging.html), e.g. :`metricbeat -e -d "*"`
- Provide the Metricbeat configuration file.

Thank you.

Hi there

Answering to all your questions.

- Is the first time that I installed it.
- This error happens when I start Metricbeat
- Yes, in fact I am using localhost as sqlserver
- The version is 7.6.0
- my metric beat file
- my mssql module file

```auto
- module: mssql
  metricsets:
    - "transaction_log"
    - "performance"
  hosts: ["sqlserver//:userdb:passworddb@localhost"]

```

The username and password must be that of the master database?.

If so, is there any way to encrypt that password, so that it is not seen in the configuration file?

Thanks for all.

Not sure if this will help, but could you try separate username and password into separate parameters? Like:

```auto
- module: mssql
  period: 10s
  metricsets:
    - "transaction_log"
    - "performance"
  hosts: ["sqlserver//localhost"]
  username: userdb
  password: passworddb

```

</div>

I believe you can use environment variables for username and password so it won't show up in the config file. For example:

```auto
- module: mssql
  period: 10s
  metricsets:
    - "transaction_log"
    - "performance"
  hosts: ["sqlserver//localhost"]
  username: '${USERNAME:""}'
  password: '${PASSWORD:""}'

```

Hi @Jose_Campos 🙂

Can you check setting the host to `sqlservertest` to see if it's taking the host from the wrong place?
