2014-05-12graph.php: use JSON plugins instead of including PHP plugin filesPim van den Berg1-0/+24
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.

2014-05-03inc/collectd: consistently return false instead of an empty array or falsePim van den Berg1-15/+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

The snmp plugin is saving if_octets this way: <host>/snmp/if_octets-<port>.rrd Where the interfaces plugin is saving if_octets with this structure: <host>/interface-<port>/if_octets.rrd

For example when a non existing plugin is defined in $CONFIG['overview'] it causes a lot of php warnings/notices.

2012-09-07add support for varnish plugin categoriesPim van den Berg1-21/+17
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.

2010-10-04inc/collectd: improve determining which files to group in 1 graphPim van den Berg1-33/+44
Previously graphs were created by collecting and merging all PIs, Ts and TIs separately. This went wrong when a part of a plugin had a PI and another part had not (processes plugin). It also went wrong when a P-PI combination had different Ts and TIs (bind plugin). This is solved by using grouped and deduplicated plugindata. -- P = plugin, PI = plugin instance, T = type, TI = type instance
2010-09-19inc/collectd: simplify the way collectd_plugindata gathers its dataPim van den Berg1-23/+10
A couple of preg_replaces are replaced by one simple but effective preg_match.

2010-01-01show all type instances in one graphPim van den Berg1-1/+3
Planned for collectd version 5.0 is to move the type instance of plugins df and interface to the plugin instance (see source). From version 5.0 the default is to group data from a type instance OR data source in one graph. In case of version 4 there are only 2 plugins to exclude from this: df and interface.

2009-12-31rewrite of type classesPim van den Berg1-17/+0
A constructor is added to the Type_Default class. The constructor will parse GET values (such as host, plugin, pinstance, type, tinstance, seconds), create an array of all needed rrd files to generate a graph and substract identifiers from these rrd files. Because of the constructor (and related functions) it is not needed to define an array of tinstances to be grouped and shown in one graph. Also $obj->args don't have to be defined per plugin. This will result in smaller plugin files. The type classes are based on the fact that a plugin has multiple type instances OR multiple rrd data sources. This is called the source and is retrieved by rrd_get_sources in each rrd_gen_graph function. Also variables in function rrd_gen_graph have been renamed to better ones.
2009-11-04add unixsock flush supportPim van den Berg1-0/+81
Via the UnixSock plugin of Collectd it is possible to send commands to the Collectd daemon. One of the commands is the FLUSH command, which you can use to let the daemon write cached data to the rrd files. CGP uses the FLUSH command before generating a graph and before showing the load information on the main page. In this case the information shown via CGP is always up-to-date. Also when you have configured the RRDTool plugin of Collectd with a CacheTimeout setting. This commit includes code based on functions collectd_identifier and collectd_flush from php-collection by Bruno Prémont.
