redis-stat is a simple Redis monitoring tool written in Ruby.

It is based on INFO command of Redis, and thus generally won't affect the performance of the Redis instance unlike the other monitoring tools based on MONITOR command.

redis-stat allows you to monitor Redis instances

• either with vmstat-like output from the terminal
• or with the dashboard page served by its embedded web server.

gem install redis-stat 

If you have trouble setting up a Ruby environment, you can download the executable JAR file and use it instead.

usage: redis-stat [HOST[:PORT][/PASS] ...] [INTERVAL [COUNT]] -a, --auth=PASSWORD Password -v, --verbose Show more info --style=STYLE Output style: unicode|ascii --no-color Suppress ANSI color codes --csv=OUTPUT_CSV_FILE_PATH Save the result in CSV format --es=ELASTICSEARCH_URL Send results to ElasticSearch: [http://]HOST[:PORT][/INDEX] --server[=PORT] Launch redis-stat web server (default port: 63790) --daemon Daemonize redis-stat. Must be used with --server option. --version Show version --help Show this message 

redis-stat redis-stat 1 redis-stat 1 10 redis-stat --verbose redis-stat localhost:6380 1 10 redis-stat localhost localhost:6380 localhost:6381 5 redis-stat localhost localhost:6380 1 10 --csv=/tmp/output.csv --verbose 

When --server option is set, redis-stat will open up an embedded web server (default port: 63790) in the background so that you can monitor Redis in your browser.

Since redis-stat pushes updates every interval via Server-sent events, modern browsers are required to view the page.

redis-stat --server redis-stat --verbose --server=8080 5 # redis-stat server can be daemonized redis-stat --server --daemon # Kill the daemon killall -9 redis-stat-daemon 

If you're running Windows, you can only install redis-stat on JRuby. Notice that fancy terminal colors will not be printed as they are not supported in the default Windows command prompt.

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Added some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

You need two Redis servers running on localhost with port 6379 and 6380 with no password.

bundle install bundle exec rake test

Since this project was supposed to be a vmstat-like monitoring script for Redis, naming it redis-stat seemed like a nice idea. That was when I was unaware of the existence of the original redis-stat included in redis-tools written by the creator of Redis himself. (My bad) Although the original C-version hasn't been updated for the past couple of years, you might want to check it out first.
