* inc/collectd: get_host_rrd_files: filter non-plugin .rrd filesPim van den Berg2014-07-241-1/+4

* Update html.inc.phpFrançois LASSERRE2014-07-231-6/+6

* Better x and y validation, report 400 on errorsPeter Wu2014-07-211-1/+1
| | | | | | | | | Report 400 Bad Request on query errors instead of reporting 200 OK (which can be cached). Add some additional validation for the 'x' and 'y' parameters, to catch underflow (test with `x=-10` for example). Also fix a typo in the error message and include more details (the actual error).
* Fix overly permissive hostname validation, fix host checkPeter Wu2014-07-211-2/+2
| | | | | | | | | `[\w\W]` matches EVERYTHING. Validation failed. Also remove `\d` as that `\w` is a superset of it. Also check that the host parameter is actually non-empty, otherwise `collectd_plugins` will happily return results as the directory `$CONFIG['datadir'] . '/' . ''` trivially exists...
* Escape file argument for rrd_infoPeter Wu2014-07-201-2/+7
| | | | Also init info_array in case the output is empty.
* Fix type confusionPeter Wu2014-07-201-3/+3
| | | | | | | | | index.php expects that collectd_hosts() always return an array for array_diff. Since an empty array evaluates to FALSE anyway, do not change the type and just return the empty array. In base.php, if no files are returned, the loop is never called and three variables are not initialized. Do it now.
* Defensive programming: more urlencode/htmlentitiesPeter Wu2014-07-201-47/+51
| | | | | | | | | | | | | | | | | | Make build_url return an URL, not HTML. This separates presentation from data. plugin_header's return value is unused, remove the unnecessary return. At places where `printf("<tag att='%s'>", $x);` is used, it is now converted to `printf("<tag att=\"%s\">", htmlentities($x));` since the single quote is not escaped by default by htmlentities. In case the canvas style is used, JS should use `textContent` instead of `innerHTML` to avoid reading `&quot;` instead of `"`. Nobody (should) use(s) IE6 anymore, so it is a safe change. While at it, use the standard charset attribute of meta to specify the character set (UTF-8).

* inc/html.inc.php: fix canvas graphsPim van den Berg2014-05-141-1/+1
| | | | Include graph.php instead of non-existing plugin/$plugin.php.
* graph.php: use JSON plugins instead of including PHP plugin filesPim van den Berg2014-05-122-0/+211
| | | | | | | | | | | | A couple of big changes here. A lot of logic moved to graph.php. The PHP plugin files have been rewritten to JSON. In these JSON files *everything* is optional. Also *NOT* having a JSON plugin file won't block you from having a graph. The JSON will just make the graphs prettier (by having a title, y-axis title, legend, colors, etc..). The Collectd types.db file is parsed and used to determine RRD content. When things are not defined in the JSON it will fallback to a default.

* inc/collectd: consistently return false instead of an empty array or falsePim van den Berg2014-05-031-15/+17
| | | | | | | | | This means we have to check the return value of these functions for example before doing a foreach. We can't just do a foreach and assume the return value of a function is an array, while it can be false and results in a PHP warning. Closes: https://github.com/pommi/CGP/pull/68

| | | | | | | | | | | | | | | Since commit collectd-4.10.0-88-g02e12db the varnish plugin groups collected values in categories. The collectd filestructure used for varnish is now: <plugin>-<category>-<plugin_instance>/<type>-<type_instance> Because this isn't distinguishable from a regular plugin like df, ... df-var-tmp/df_complex-free.rrd ("var" isn't the category here) ... the category is only set with the varnish plugin.
