This page document a quick way of installing the agent. For production system, you may want to use trusted certificate and other enhancement.
In order to run temBoard agent, you need:
- Linux as underlying OS.
- PostgreSQL 9.4+, listening on UNIX socket. Check with
sudo -u postgres psql.
- Python 2.6+ or 3.5+. Check with
- A running temBoard UI.
- bash, curl and sudo for setup script.
The temBoard agent must run on the same host as the PostgreSQL instance. Running an agent on a remote host is not yet supported.
Now choose the method matching best your target environment.
temBoard debs are published on Dalibo Labs APT repository. temBoard agent supports Debian buster and stretch. 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 7 and 8. 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
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
Some production infrastructure are offline for security reasons. In this situation, the temboard-agent package and its dependencies can be dowloaded with the following commands :
$ sudo yum install yum-utils $ yumdownloader --resolve --destdir /tmp/temboard-packages temboard-agent
Then the downloaded packages can be transfered to the production server and installed with
$ yum --disablerepo=* localinstall *.rpm
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
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
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.
Each agent is identified by the fully qualified hostname. If
hostname --fqdn can\'t resolve the FQDN of your HOST, simply overwrite
TEMBOARD_HOSTNAME envvar. Remember that
localhost or even a
short hostname is not enough.
auto_configure.sh enforces this.
The script shows you some important information for the next steps:
- the path to the main agent configuration file like
Some parts of the configuration are in
/etc/temboard-agent/11/main/temboard-agent.conf.d/auto.conf too and
override the main configuration file.
- agent TCP port (usually 2345 if this is your first agent on this host)
- secret key for registration like
You will need these information later. Keep them near. Now create a
first user (specific to this agent) using
Later, once the agent is registered, you will need to authenticate
against the agent with this user from the UI to interact with the agent.
# sudo -u postgres temboard-agent-adduser -c /etc/temboard-agent/11/main/temboard-agent.conf
Adapt the configuration file name to match the one created by
Now start the agent using the command suggested by
On most systems now, it\'s a systemd service:
# systemctl start temboard-agent@11-main
Check that it has started successfully:
# systemctl status temboard-agent@11-main
Now you can register the agent in the UI using
temboard-agent-register. It needs the configuration file path, the
agent host and port and the path to the temBoard UI.:
# 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
temboard-agent-register will ask you to login to the UI (eg.
if you\'ve kept the default temBoard user). Beware, it is NOT the
user set on the agent.
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.
Cleaning agent installation¶
If you need to clean a single agent installation either to uninstall it
or to run
auto_configure.sh again, use
purge.sh with cluster name.
# /usr/share/temboard-agent/share/purge.sh 12/main Stopping and disabling systemd service. Removed /firstname.lastname@example.org. Cleaning files and directories... removed '/etc/temboard-agent/12/main/temboard-agent.conf' removed '/etc/temboard-agent/12/main/temboard-agent.conf.d/auto.conf' removed directory '/etc/temboard-agent/12/main/temboard-agent.conf.d' removed '/etc/temboard-agent/12/main/users' removed directory '/etc/temboard-agent/12/main/' removed directory '/var/lib/temboard-agent/12/main/' temBoard agent 12-main stopped and cleaned. #
