diskspaced is a Pyro frontend for querying the current disk usage.
diskspace is a commandline utility that queries the disk space daemon.
Configuration is read from json files that are installed by default to /etc/diskspaced.
A configuration file is specified when launching the server, and the diskspace frontend will search this location when launched.
The configuration options are:
{
"daemon": "localhost_test2", # Run the server as this daemon. Daemon types are registered in `rockit.common.daemons`.
"log_name": "diskspaced@test", # The name to use when writing messages to the observatory log.
"data_root_path": "/home/ops" # The file system path to monitor.
}The automated packaging scripts will push 8 RPM packages to the observatory package repository:
| Package | Description |
|---|---|
| rockit-diskspace-server | Contains the diskspaced server and systemd service file. |
| rockit-diskspace-client | Contains the diskspace commandline utility for querying the server. |
| rockit-diskspace-data-clasp | Contains the json configuration for the CLASP DAS machine. |
| rockit-diskspace-data-halfmetre | Contains the json configuration for the half metre TCS. |
| rockit-diskspace-data-onemetre | Contains the json configuration for the W1m TCS. |
| rockit-diskspace-data-sting | Contains the json configuration for the STING DAS machines. |
| rockit-diskspace-data-warwick | Contains the json configuration for the Windmill Hill TCS. |
| python3-rockit-diskspace | Contains the python module with shared code. |
After installing packages, the systemd service should be enabled:
sudo systemctl enable --now diskspaced@<config>
where config is the name of the json file for the appropriate telescope.
Now open a port in the firewall:
sudo firewall-cmd --zone=public --add-port=<port>/tcp --permanent
sudo firewall-cmd --reload
where port is the port defined in rockit.common.daemons for the daemon specified in the server config.
New RPM packages are automatically created and pushed to the package repository for each push to the master branch.
These can be upgraded locally using the standard system update procedure:
sudo yum clean expire-cache
sudo yum update
The daemon should then be restarted to use the newly installed code:
sudo systemctl restart diskspaced@<config>
The camera server and client can be run directly from a git clone:
./diskspaced config/test.json
DISKSPACED_CONFIG_PATH=./config/test.json ./diskspace status
