Ever had a problem to Identify your current replica master? Or just wanting to grep some metrics or uptimes about your database? This small tool might help you!

dbm reads in a yaml configuration that can be stored on multiple paths (/etc/dbm/config.yaml, ./config.yaml, $HOME/.dbm/config.yaml) The configuration is used for all commands.

logfile: test.log # your logfile (if not set none will be created)
debug: false # enable this for debug logs 
test_timeout: 5 # maximum runtime of a test until it will be canceled
test_interval: 30 # interval when to run the next test
databases: # your database configurations
  - host: localhost
    port: 5432
    username: postgres
    password: postgres # <- I know this is not nice yet, I will try to provide another way for configuration soon
    database: postgres
    use_ssl: true
    SSLCertPath: /some/path
    SSLKeyPath: /some/path
    SSLRootCertPath: /some/path
    connection_timeout: 5
  - host: localhost
    port: 5433
    username: postgres
    password: postgres
    database: postgres
    connection_timeout: 5

There is an easy way to setup your databases to support this tool. As it does some read/write testing you need to have a table created. Right now the table is hardcoded as test. In order to set it up, just configure your databases and execute dbm setup

If you want to make an initial test locally, please use dbm local. This will just run the database tester and provide you with information about their behaving.

This command serves the results of the tester as json.
