Description:
# DIMA

A command-line tool to list, inspect and kill database queries.

We've been using this tool since 2017 at Frame.io and decided to open source it. There will be a blog post with more details on the Frame.io Engineering Blog soon. Previous git history has been wiped by our security team.

# Setup:

1. Clone this repo
2. Set up the credentials (see below)
3. Run: `python setup.py install`

(homebrew setup is being worked on)

# Credential Setup

Database credentials can be provided in 2 ways - in a `~/.dima_creds` file or as environment variables. DIMA will look first for the environment variables, and then to the creds file. You can set the following environment variables:

DIMA_DB_DBNAME
DIMA_DB_USER
DIMA_DB_HOST
DIMA_DB_PORT
DIMA_DB_PASSWORD

or place them in a `~/.dima_creds` file (the prefix `~/` means that it should be in your home directory). A sample file `sample_creds` is in this repo.

You can add more credentials for different databases underneath, as long as they use a different prefix. E.g.

DIMA_DB2_DBNAME
DIMA_DB2_USER
...

To inspect a non-default DB, use the `-c` option, e.g. for a prefix `DIMA_DB2_...` use:

dima -c DB2 show 123

# Usage:

dima
Shows a list of running queries

dima show [PID]
Inspects a specific running query

dima rm [-f] [Lock / filter keyword / PID]

Terminates queries either with `wait_event_type` "Lock" or according to a filter keyword or PID. Use -f to avoid the confirmation.
