Watchmonkey is a very simple tool to monitor resources with Ruby without the need of installing agents on the systems you want to monitor. To accomplish this the application polls information via SSH or other endpoints (e.g. websites, FTP access). It's suitable for small to medium amounts of services.
Before looking any further you might want to know:
- There is no escalation or notification system (except experimental telegram bot) but you may add it yourself
- I originally created this for being used with Platypus hence the Platypus Hook
- This is how the text output looks like: Screenshot
- This is how the Platypus support looks like: ProgressBar HTML/WebView
- This is how Telegram Bot looks for now: Telegram Screenshot
If you need help or have problems open an issue.
- Monitor external resources (Web, FTP, Server health via SSH)
- Run once or loop forever with ReQueue (define intervals globally, per checker or per single test)
- Includes a selection of buildin checkers (see list or config template)
- Ruby >= 2.0
- Unixoid OS (such as Ubuntu/Debian, OS X, maybe others) or Windows (not recommended)
- something you want to monitor
gem install watchmonkey_cli
watchmonkey --generate-config [name=default]
- Edit the created file to fit your needs
- Check out the additional features below (e.g. ReQueue)
To get a list of available options invoke Watchmonkey with the
Usage: watchmonkey [options] # Application options --generate-config [myconfig] Generates a example config in ~/.watchmonkey -l, --log [file] Log to file, defaults to ~/.watchmonkey/logs/watchmonkey.log -t, --threads [NUM] Amount of threads to be used for checking (default: 10) -e, --except tag1,tag2 Don't run tasks tagged with given tags -o, --only tag1,tag2 Only run tasks tagged with given tags -s, --silent Only print errors and infos -q, --quiet Only print errors # General options -d, --debug [lvl=1] Enable debug output -m, --monochrome Don't colorize output -h, --help Shows this help -v, --version Shows version and other info -z Do not check for updates on GitHub (with -v/--version) --dump-core for developers
Writing a documentation takes time and I'm not sure if anyone is even interested in this tool. If there is interest I will write a documentation but for now this Readme must suffice. If you need help just open an issue :)
--generate-config option or refer to the configuration template for examples and documentation.
If you want to deactivate single configs just rename the file to start with two underscores (e.g.:
If you want to add custom checkers, hooks or change default settings you can create
~/.watchmonkey/config.rb. The file will be eval'd in the application object's context. Take a look at the example configuration file and application.rb.
If you want to monitor something that is not covered by the buildin handlers you can create your own, it's not that hard and should be a breeze if you are used to Ruby. All descendants of the
WatchmonkeyCli::Checker class will be initialized and are usable in the application. Documentation is thin but you can take a look at the example checker, the buildin checkers or just open an issue and I might just implement it real quick.
By default Watchmonkey will run all tests once and then exit. This addon will enable Watchmonkey to run in a loop and run tests on a periodic interval. Since this seems like a core feature it might get included directly into Watchmonkey but for now take a look at the application configuration file and ReQueue source code for integration examples.
Notify via Telegram. Experimental. Refer to application configuration file and TelegramBot source code for further information.
- works with ReQueue (wouldn't make much sense otherwise huh?)
- optional per-user message throttling via checker uniqid (checker name + host + arguments)
- optional per-user only/except filters based on tags
- planned: robust telegram connection failure handling
- planned: per-user regex exclusion filters
Platypus is a MacOS software to create dead simple GUI wrappers for scripts. There is buildin support for the interface types ProgressBar and WebView. For integration examples take a look at the application configuration file and Platypus hook source code.
