This tool shows up/warn/down state of configured hosts or applications using i3bar input protocol.

Usage

You should create a configuration file .checkbar.toml in your home directory, e.g.

# Update interval in seconds. Default value if not set is 60 sec.
interval = 60

[[checks]]
name = "Host 1"
url = "https://host1.example.com"

[[checks]]
name = "Host 2"
url = "https://host2.example.com"

[[checks]]
name = "App 1"
url = "https://app.example.com/actuator/health"
check_type = "Actuator"

Each host or application to be checked constists of name and url.

You can optionally specify check_type:

• Html: Default value, checks if a request is succeessful and returns HTTP OK - 200.

• Actuator: Like Html, but checks if Actuator shows that the application is up and running.

Execute commands

This feature is experimental and starts further commands only after previous commands have been finished.

You can also specify a command to be executed when a mouse click occurs on a checked host. Use click_cmd to specifiy the command to be executed, e.g.

...
[[checks]]
name = "Host 1"
url = "http://host1.example.com"
click_cmd = "xterm -e ssh admin@host1.example.com"
...
