===== cstat ===== *A visual stat tool for CrateDB clusters.* ``cstat`` is ispired by the awesome interactive process monitoring tool htop_. ``cstat`` should be a similar tool to iostat_, but for monitoring CrateDB_ clusters. .. image:: screenshot.png :scale: 100% :alt: Screenshot of cstat in action Requirements ============ ``cstat`` requires **Python >= 3.6** and can connect to **CrateDB >= 2.3**. Installation ============ ``cstat`` is available from Pypi_ so you can install it using pip_. :: pip install cstat If you want to get the latest features and fixes, you can also install it directly from Github_. :: pip install git+https://github.com/chaudum/crate-top.git@master Usage ===== After installation you can monitor CrateDB running on localhost with default configuration by invoking the following command:: >>> cstat --user crate A full list of command line arguments are listed when invoking ``cstat`` with the ``--help`` argument:: >>> cstat --help usage: cstat [-h] [--host HOST] [--port PORT] [--interval INTERVAL] [--user USER] [--version] A visual stat tool for CrateDB clusters optional arguments: -h, --help show this help message and exit --host HOST, --crate-host HOST CrateDB host to connect to --port PORT, --psql-port PORT PSQL port of CrateDB host --interval INTERVAL, --refresh-interval INTERVAL amount of time in seconds between each update --user USER, --db-user USER database user --version show program's version number and exit By default ``cstat`` connects to ``localhost`` on port ``5432`` if not otherwise specified. Keyboard Shortcuts ================== - ``0`` ... toggle cluster info - ``1`` ... show utilization for CPU, process, memory, heap and disk - ``2`` ... show I/O statistics for network and disk - ``3`` ... show aggregated query duration based on jobs_log_ - ``x`` ... toggle nodes/aggregation view - ``f3`` ... enable/disable job logging (this also sets the ``stats.jobs_log`` cluster setting) Known Issues ============ - Small terminal sizes will raise CanvasErrors because of content overflow. Todo ==== - [x] display disk usage - [x] display disk i/o - [x] display network i/o - [x] display node names in detail views - [x] use asyncio to perform http requests - [x] coloring of i/o stats - [ ] responsive i/o widget .. _htop: http://hisham.hm/htop/ .. _iostat: http://linux.die.net/man/1/iostat .. _CrateDB: https://crate.io .. _aiopg: https://github.com/aio-libs/aiopg .. _Pypi: https://pypi.org/project/cstat/ .. _pip: https://pypi.org/project/pip/ .. _Github: https://github.com/chaudum/crate-top .. _jobs_log: https://crate.io/docs/reference/en/latest/configuration.html#collecting-stats =================== Changelog for cstat =================== Unreleased ========== 0.3.0 ===== Released on **2018/06/01** with the following changes: - Make cstat compatible with CrateDB version 2.3.0 and greater. - Updated process CPU usage calculation to work with CrateDB 2.3 and newer. - Updated disk usage and disk i/o calculation to work with CrateDB 2.3 and newer. - Added ``-V`` (prompt for username) argument. - Added ``--password`` and ``-W`` (prompt for password) arguments. 0.2.0 ===== Released on **2017/11/14** with the following changes: - Implemented asynchronous database access using aiopg_ which uses the Postgres Wire Protocol instead of the official CrateDB Python client which uses the HTTP protocol. - Added ``median``, ``percentile 95``, and ``percentile 99`` to query stats table view. - Added ``--user``/``--db-user`` command line argument to support user authentication for clusters which run CrateDB 2.0 or greater. - Changed the toggle key for enabling/disabling query stats from ``F1`` to ``F3``, because in the Terminator_ terminal the ``F1`` key is reserved for "help". - Pre-calculate used and idle CPU in SQL statement to avoid rounding issues that can cause an display overflow in CPU widget. .. _aiopg: https://github.com/aio-libs/aiopg .. _Terminator: https://launchpad.net/terminator 0.1.0 ===== Initial release on **2017/03/30**:
