title: Monit web status to JSON with PHP

---

Monit[^1]'s web interface is pretty easy to read for a human, but
incredibly ugly to parse. In order to show a machine-readable output, it
needs to be parsed to JSON.

You'll need PHP Simple HTML DOM Parser[^2] for it, and this script to
show the JSON output: `monit2json.php`

``` {.php}
<?php

include ('simple_html_dom.php');
$html = file_get_html('http://127.0.0.1:2812/');

$contents = array();

$cntr_table = 0;
foreach ( $html->find('table[id=header-row]') as $table ) {

    $cntr_tr = 0;
    foreach ( $table->find('tr') as $tr ) {

        $cntr_td = 0;
        foreach ( $tr->find('th') as $th ) {
            $columns [ $cntr_td ] = strip_tags ( $th->innertext );
            $cntr_td++;
        }

        $cntr_td = 0;
        foreach ( $tr->find('td') as $td ) {
            $contents[ $cntr_table ][ $cntr_tr ][ $columns[ $cntr_td ] ] =  str_replace( '&nbsp;', ' ', strip_tags( $td->innertext ) );
            $cntr_td++;
        }

        $cntr_tr++;
    }

    $cntr_table++;
}

foreach ( $contents as $table  ) {
    foreach  ( $table as $process ) {
        if ( isset ( $process['Process'] ) ) {
            $proc = $process['Process'];
            unset ( $process['Process'] );

            $out[ $proc ] = $process;
        }
    }
}

$out = json_encode ( $out, JSON_PRETTY_PRINT );
echo $out;
```

Result:

``` {.json}
