Thanks to Mariusz Gronczewski for implementing this. + * thresholds: The advanced threshold options “Percentage”, “Hits”, and + “Hysteresis” have been added. Thanks to Andrés J. Díaz for hit + patches. + * curl_json plugin: The new cURL-JSON plugin reads JSON files using + the cURL library and parses the contents according to user + specification. Among other things, this allows to read statistics + from a CouchDB instance. Thanks to Doug MacEachern for the patch. + * df plugin: Using the new “ReportByDevice” option the device rather + than the mount point can be used to identify partitions. Thanks to + Paul Sadauskas for the patch. + * dns plugin: The possibility to ignore numeric QTypes has been added. + Thanks to Mirko Buffoni for the patch. + * GenericJMX plugin: The new, Java-based GenericJMX plugin allows to + query arbitrary data from a Java process using the “Java Management + Extensions” (JMX). + * madwifi plugin: The new MadWifi plugin collects information about + Atheros wireless LAN chipsets from the MadWifi driver. Thanks to + Ondrej Zajicek for his patches. + * network plugin: The receive- and send-buffer-sizes have been made + configurable, allowing for bigger and smaller packets. Thanks to + Aman Gupta for the patch. + * olsrd plugin: The new OLSRd plugin queries routing information from + the “Optimized Link State Routing” daemon. + * rrdtool plugin: A new configuration option allows to define a random + write delay when writing RRD files. This spreads the load created by + writing RRD files more evenly. Thanks to Mariusz Gronczewski for the + patch. + * swap plugin: The possibility to collect swapped in/out pages has + been added to the Swap plugin. Thanks to Stefan Völkel for the + patch. + * tokyotyrant plugin: The new TokyoTyrant plugin reads the number of + records and file size from a running Tokyo Tyrant server. Thanks to + Paul Sadauskas for the patch. + * unixsock plugin: Add the “GETTHRESHOLD” command. This command can be + used to query the thresholds configured for a particular identifier. + * write_http plugin: The new Write HTTP plugin sends the values + collected by collectd to a web-server using HTTP POST requests. + Thanks to Paul Sadauskas for the patch. + * zfs_arc plugin: The new ZFS ARC plugin collects information about + the “Adaptive Replacement Cache” (ARC) of the “Zeta File-System” + (ZFS).

Thanks to Sebastian Harl for the patch. + * collectd: Remove old values when a cache entry is marked as missing. + This way the “GETVAL” command of the UnixSock plugin doesn't return + old, no longer valid values when this happens. Thanks to Andrés J. + Díaz for the patch. + * collectd: The “plugin_unregister_read” function has been fixed. + * apache, ascent, bind, curl, nginx plugins: Advise the cURL library + to follow redirects. Thanks to Joey Hess for reporting this bug. + * df plugin: Check the ignorelist before stating the file system, + possibly reducing the number of stats considerably. Thanks to Joey + Hess for reporting this bug. + * iptables plugin: Support for the new libiptc API has been added. + Thanks to Sebastian Harl for the patch. The build system has been + updated to the plugin only includes the shipped header files when it + is linked with the shipped library, too. + * java plugin: Delay creating the JVM until after the daemon has + forked. The JVM internally creates threads that are lost when + forking. This means that Java-based plugins are now configured + during the init-phase, i. e. later than other plugins. + * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks + to Alan Pevec for the patch. + * network plugin: Fix the handling of the “CacheFlush” option: The + value was assigned to a wrong variable. The initialization of the + gcrypt library, which is used for signing / encrypting traffic, has + been fixed. Thanks to Luke Heberling for the patch. + * powerdns plugin: Set a timeout when reading data from the datagram + socket. Handling of the “LocalSocket” option has been fixed.

The API has + been extended to support notifications and export global variables to + Perl plugins; callbacks now have to be identified by name rather than a + pointer to a subroutine. The plugin is no longer experimental. + * uuid plugin: The new UUID plugin sets the hostname to an unique + identifier for this host. This is meant for setups where each client + may migrate to another physical host, possibly going through one or + more name changes in the process.
