uptimecurl

Basic monitoring tool designed for rapid deployment and simple results.

Scheduled monitoring, dashboards, alerts and other advanced features are out of scope. Instead consider tools like crontab, Cockpit, Grafana or Zabbix.

Usage

Usage: uptimecurl [OPTIONS]

  Basic monitoring tool designed for rapid deployment and simple results.

  Define tests in the DEFINITION file and template in the TEMPLATE file.
  Report is generated at the OUTPUT path.

  Instead of command-line parameters you can use the environment variables
  UPTIMECURL_DEFINITION, UPTIMECURL_TEMPLATE and UPTIMECURL_OUTPUT. These
  can be defined in a .env file in the working directory.

Options:
  --definition FILE  List of test definitions (YAML).
  --template FILE    Template to generate report from test results (Mustache).
  --output FILE      Output path for report (typically HTML).
  --help             Show this message and exit.

Sample definition

example_http:
    type: http_ok
    parameters:
      - http://en.wikipedia.org
example_port:
    type: port_ok
    parameters:
      - en.wikipedia.org
      - 443

Sample template

See https://mustache.github.io/mustache.5.html for template language.

<tbody>
{{#data}}
  <tr>
    <td title="{{timestamp}}">
      {{name}}
    </td>
    <td title="{{parameters}}">

Sample report

Run uptimecurl without parameters to generate this sample report in HTML (hover or view source on each cell for more detail):

Name	Test	Result
example_http	http_ok	❌
example_port	port_ok	💚

Test types

http_ok

test_name:
    type: http_ok
    parameters:
      - https://example.com/path

Perform an HTTP request against any URL (parameter 0).

Return 💚 if we get a 200 OK response, ❌ otherwise.

Note that we expect strictly a 200 OK reponse. Redirects and other values will result in a failure. (See the sample report for an example of a failure.)

port_ok

test_name:
    type: port_ok
    parameters:
      - domain.com
      - 1234

Attempt to connect to domain:port (parameter 0, parameter 1).

Return 💚 if successful, ❌ otherwise.

Note that an open port does not guarantee that the underlying application is working, just that the server is up and correctly configured.
