`task-mon` is a small binary for notifying Healthchecks.io when a command runs.

This serves a similar purpose to the `curl`-based patterns described in the Healthchecks
documentation but provides more flexibility and ergonomics. Especially for shell scripts and
[cron jobs](https://healthchecks.io/docs/monitoring_cron_jobs/), delegating health management to a
separate binary allows you to focus on the task at hand.

It supports Healthchecks' advanced optional features such as
[reporting failures](https://healthchecks.io/docs/signaling_failures/),
[attaching logs](https://healthchecks.io/docs/attaching_logs/), and
[monitoring execution time](https://healthchecks.io/docs/measuring_script_run_time/).

## Usage

To execute a task and ping Healthchecks.io when it completes simply invoke `task-mon` with the
check's UUID and the command to run:

```shell
$ task-mon --uuid 1234-abcd -- some_command --to --monitor
```

```shell
$ task-mon --ping-key abcd1234 --slug foo -- some_command --to --monitor
```

```shell
$ crontab -e
# m h dom mon dow command
8 6 * * * /usr/local/cargo/bin/task-mon --uuid 1234-abcd -- some_command --to --monitor
```

`task-mon` will run the command and ping Healthchecks.io when it completes, reporting the exit
status and the last 10K of output from the process.

$ task-mon --help
task-mon 0.3.0
