Welcome to temBoard agent documentation!

temBoard is a powerful management tool for PostgreSQL.

temBoard agent is a Python service designed to run along PostgreSQL, exposing a REST API to implement various management tasks on PostgreSQL instance. See http://temboard.io/ for the big picture.

Features

  • Non intrusive daemon dedicated to one PostgreSQL cluster.
  • No extra dependencies.
  • Written python2.7 and python3, supported by stable distribution releases.
  • Secured REST API with SSL and credentials.
  • Extensible with plugins.

Installation

This page document a quick way of installing the agent. For production system, you may want to use trusted certificate and other enhancement.

Prerequisites

In order to run temBoard agent, you require:

  • PostgreSQL 9.4+, listening on UNIX socket, on the same host. Check with sudo -u postgres psql.
  • openssl.
  • Python 2.6+ or 3.5+. Check with python --version.
  • A running temBoard UI.
  • bash and sudo for setup script.

Now choose the method matching best your target environment.

Debian

temBoard debs are published on Dalibo Labs APT repository. temBoard agent supports Debian stretch, jessie and wheezy. Start by enabling Dalibo Labs APT repository.

# echo deb http://apt.dalibo.org/labs $(lsb_release -cs)-dalibo main > /etc/apt/sources.list.d/dalibo-labs.list
# curl https://apt.dalibo.org/labs/debian-dalibo.asc | apt-key add -
# apt update -y  # You may use apt-get here.

You can install now temBoard agent with:

# apt install temboard-agent
# temboard-agent --version

RHEL / CentOS

temBoard RPM are published on Dalibo Labs YUM repository. temBoard agent supports RHEL / CentOS 6 and 7. Start by enabling Dalibo Labs YUM repository.

$ sudo yum install -y https://yum.dalibo.org/labs/dalibo-labs-2-1.noarch.rpm
$ sudo yum makecache fast

Warning

Do NOT use temBoard agent rpm from PGDG. They are known to be broken.

With the YUM repository configured, you can install temBoard agent with:

$ sudo yum install temboard-agent
$ temboard-agent --version

PyPI

temBoard agent wheel and source tarball are published on PyPI.

Installing from PyPI requires Python2.6+, pip and wheel. It’s better to have a recent version of pip. For Python 2.6, you will need some backports libraries.

$ sudo pip install temboard-agent
$ sudo pip2.6 install logutils argparse  # Only for Python 2.6
$ temboard-agent --version

Note where is installed temBoard agent and determine the prefix. You must find a share/temboard-agent folder in e.g /usr or /usr/local. If temBoard agent is installed in /usr/local, please adapt the documentation to match this system prefix.

Setup one instance

To finish the installation, you will need to follow the next steps for each Postgres instance on the host:

  • configure the agent;
  • add a first user;
  • start the agent;
  • finally register it in the UI.

The quickest way to setup temBoard agent is to use the auto_configure.sh script, installed in /usr/share/temboard-agent.

You must run this script as root, with PG* env vars set to connect to the Postgres cluster you want to manage. By default, the script uses postgres UNIX user to connect to Postgres cluster. The script receives the temBoard UI URL as single required argument.

Note

Each agent is identified by the fully qualified hostname. If hostname --fqdn can’t resolve the FQDN of your HOST, simply overwrite it using TEMBOARD_HOSTNAME envvar. Remember that localhost or even a short hostname is not enough. auto_configure.sh enforces this.

# /usr/share/temboard-agent/auto_configure.sh https://temboard-ui.lan:8888

The script shows you some important information for the next steps:

  • the path to the main configuration file like /etc/temboard-agent/11/main/temboard-agent.conf.
  • TCP port like 2345.
  • secret key for registration like d52cb5d39d265f03ae570e1847b90e10.

You will need these information later. Keep them near. Now add a first user using temboard-agent-adduser:

# sudo -u postgres temboard-agent-adduser -c /etc/temboard-agent/11/main/temboard-agent.conf

Adapt the configuration file to match the one created by auto_configure.sh. Later, once the agent is registered, you will need to authenticate against the agent with this user, right from the UI.

Now start the agent using the command suggested by auto_configure.sh. On most systems now, it’s a systemd service:

# systemctl start temboard-agent@11-main

Now you can register the agent in the UI using temboard-agent-register:

# sudo -u postgres temboard-agent-register -c /etc/temboard-agent/11/main/temboard-agent.conf --host $(hostname --fqdn) --port 2345 --groups default https://temboard-ui.lan:8888

Don’t forget to adapt this command line to your case. Configuration file, port and temBoard UI address are likely to change from one installation to another. temboard-agent-register will ask you to login to the UI. Beware, it is NOT the user on the agent.

It’s up!

Congratulation! You can continue on the UI and see the agent appeared, and monitoring data being graphed.

You can repeat the above setup for each instance on the same host.

Configuration

temBoard agent reads configuration from arguments, environment and file. Defaut configuration file is /etc/temboard-agent/temboard-agent.conf. You can change this with TEMBOARD_CONFIGFILE envvar or --configfile switch.

temBoard agent always searches for a directory whose name is built with the config file and the .d suffix. Thus the default config directory is /etc/temboard-agent/temboard-agent.conf.d. temBoard agent reads only files suffixed with .conf. temBoard agent reads files in POSIX sort order: uppercase precedes lowercase.

The configuration file is mandatory. The configuration directory is optional.

The configuration file is in INI-style format as implemented by Python stlib config parser. Configuration parameters are distributed under sections:

  • temboard: this is the main section grouping core parameters;
  • postgresql: parameters related to the PostgreSQL cluster that the agent is connected to;
  • logging: how and where to log;
  • dashboard: parameters of the plugin dashboard;
  • monitoring: plugin monitoring;
  • administration: plugin administration,
  • maintenance: plugin maintenance.

Contributing

Reporting Issue & Submitting a Patch

We use dalibo/temboard-agent to track issue and review contribution. Fork the main repository and open a PR against master as usual.

Docker Development Environment

First, ensure you have properly cloned temboard-agend repository. The project uses a submodule. Either clone with --recursive flag or activate submodule.

$ git clone --recursive https://github.com/dalibo/temboard-agent.git
$ cd temboard-agent/
$ git submodule update --init

With Docker & Compose, you can run your code like this:

$ docker-compose up -d
$ docker-compose exec agent bash
# pip install -e /usr/local/src/temboard-agent/
# sudo -u postgres temboard-agent

Goto https://0.0.0.0:8888/ to add your instance with address agent, port 2345 and key key_for_agent_dev.

That’s it !

The make shell target is a shorthand to docker-compose exec agent bash if you prefer.

Editing Documentation

Sphinx generates temBoard agent documentation.

$ cd docs/
$ pip install -r requirements-doc.txt
$ make watch

Now run make serve in another terminal and point your web browser at http://0.0.0.0:8000/. There is no auto-refresh.

Releasing

Releasing a new version of temBoard agent requires write access to master on main repository, PyPI project and Docker Hub repository.

For the tooling, you need Git 1.8+, a recent setuptools with wheel, and twine. For debian packaging, see below.

Please follow these steps:

  • Checkout the release branch, e.g. v2.
  • Choose the next version according to PEP 440 .
  • Update temboardagent/version.py, without committing.
  • Generate commit and tag with make release.
  • Push Python egg to PyPI using make upload.
  • Build and push RPM packages using make -C packaging/rpm all push.
  • Build and push debian packages using make -C packaging/deb all push.
  • Trigger docker master build from https://hub.docker.com/r/dalibo/temboard-agent/~/settings/automated-builds/.

Other documentation for maintainers

Packaging for Debian GNU/Linux

The packaging/deb directory contains debian packaging of temBoard agent from released tarball on PyPI.

Building and uploading

The all target builds packages for every supported distributions while push targets run dput on the latest .changes. Once you have setup your host for building, just run:

make all push

You may be prompted for a passphrase to open your private key. The packages are stored in dist/ at the root of the project.

Setup

Package building requires Docker and Docker Compose for isolation. For signing, you need the devscripts package and a GPG private key. For uploading, you require dput.

sudo apt install devscripts dput

Ensure dput is configured to send to Dalibo Labs APT repository with the configuration named labs.

Now, export your full name and email address in DEBFULLNAME and DEBEMAIL env vars before building the packages. The maintainer field of the package is formatted as $DEBFULLNAME <$DEBEMAIL>.

debsign signs .changes with the GPG signature matching the maintainer field $DEBFULLNAME <$DEBEMAIL>.

Development

First, run docker container for interactive usage:

docker-compose run --rm stretch /bin/bash

If you get no output just after the run, type ENTER or CTRL+L to redraw.

Top srcdir is mounted as /workspace/ and dist/ is mounted as /dist/. Just call /workspace/packaging/deb/mkdeb.sh to build debian package.

Once you quit the shell, the container is destroyed.

Packaging for RHEL / CentOS

The packaging/deb directory contains debian packaging of temBoard agent from released tarball on PyPI or from a snapshot.

Building and uploading

The all target builds packages for every supported distributions and put them in upload directory. push target effectively upload RPMs to Dalibo Labs YUM repository. Once you have setup your host for building, just run:

make all push

The packages are stored in dist/rpm/ at the root of the project.

Building a snapshot

You can override the version to be built using VERSION env var. Ensure you have the corresponding source tarball in dist/ directory, otherwise, the script will try to download the sources from PyPI.

python setup.py sdist
VERSION=$(python setup.py --version) make -C packaging/rpm/ all push
Setup

Package building requires Docker and Docker Compose for isolation. For uploading, you need to have yum-labs project aside temboard-agent clone.

Development

The RPM spec file supports building a package for RHEL / CentOS version 6 and 7. To do so, it uses tests on the version, provided by the %{rhel} macro.

First, run docker container for interactive usage:

docker-compose run --rm centos7 /bin/bash

If you get no output just after the run, type ENTER or CTRL+L to redraw.

Top srcdir is mounted as /workspace/. Just call /workspace/packaging/rpm/build.sh to build the RPM package.

Once you quit the shell, the container is destroyed.
