Release Notes: Six new plugins add support for Aquaero fan controllers, Linux cgroups containers, Linux Logical Volume Manager (LVM), Intel's Many Integrated Core architecture, the sigrok library, and the StatsD network protocol. The new "AutoLoadPlugin" option gives users the option to have plug-ins loaded automatically as needed. Numerous new features have been added in existing plugins.
Release Notes: The NetApp, Python, RouterOS, ContextSwitch, Monitorus, and OpenVZ plug-ins have been added. Support for AIX has been added to the CPU, Disk, Interface, Load, Memory, Processes, and Swap plug-ins. Timing information is now collected in the cURL plugin. The possibility to set the source address and device used has been added to the Ping plug-in. The detail provided by the DF plug-in has been enhanced. Collection of IO-metrics has been added to the Processes plug-in.
Release Notes: Support for the data source types “derive” and “absolute” has been added. Threshold checking has been enhanced. New plugins fetch JSON data from CouchDB or Hadoop servers, analyze Java processes via JMX, and query statistics from the TokyoTyrant database, the MadWifi driver, the OLSRd routing daemon, or the ZFS cache. The “Write HTTP” plugin sends data in plain text or JSON to a HTTP server using POST requests. The new “Empty Counter” match detects and helps to ignore inactive counters. The existing DF, DNS, Network, Swap, and UnixSock plugins have been enhanced.
Release Notes: The abilty to sign or encrypt network traffic has been added to the network plug-in. A new plug-in embeds a Java VM that allows you to load and run plug-ins written in Java. Other new plug-ins allow the daemon to collect the size of the connection tracking table under Linux, details about the FS-Cache feature of Linux 2.6.30, detailed network protocol data, and power consumption via T.E.D. devices. The new memcachec plug-in parses data fetched from a memcached server. Ganglia interoperability has been added. Statistics collected by the MySQL plug-in have been extended.
Release Notes: An infrastructure for filtering and manipulating values has been added to the daemon. A communication and control library has been added. Plug-ins for BIND, cURL, DBI, OpenVPN, Oracle, and RRDCacheD have been added. New features have been added to the CSV, Interface, memcached, MySQL, PostgreSQL, and Processes plug-ins. The CPU and Swap plug-ins have been ported to OpenBSD. Error handling and/or portability has been improved in the IPMI and Perl plug-ins.
Release Notes: Six new plugins have been added: "filecount", "notify_desktop", "notify_email", "onewire", "postgresql", and "thermal". The ability to throttle the writing speed has been added to the "rrdtool" plugin. Flushing of specific identifiers has been added. Support for plugins written in Perl has been improved. The "ipmi" plugin can now create notifications based on the presence of devices. Grouping of multiple processes has been added to the "processes" plugin. The "tcpconns" plugin has been ported to OpenBSD.
Release Notes: Simple threshold checking and notifications have been added to the daemon. The hostname can now be set to the FQDN automatically. Inclusion files have been made more flexible by allowing shell wildcards and including entire directories. The new libvirt plugin is able to collect some statistics about virtual guest systems without additional software on the guests themselves. The perl plugin has been improved a lot. It can now handle multiple threads and is now longer considered experimental. The csv plugin can now convert counter values to rates.
Release Notes: Plugins have been added to query statistics from ipvs, memcached, and nginx. Another new plugin counts the number of TCP connections to or from a specific port. The possibility to split up the configuration into multiple files has been added in form of the new "Include" configuration option. The Perl plugin has been improved a lot; most notably, the "EnableDebugger" option was added, which makes it easier to debug plugins written in Perl. The SNMP plugin has been extended to handle more complex scenarios, for example, by scaling values.
Release Notes: The build system has been changed to disable plug-ins with unmet dependencies automatically. The interval in which the data is gathered is now included in the data itself. The network plug-in knows how to handle this so that remote setups don't need to run with the same interval setting anymore. The rrdtool plug-in writes updates in a separate thread now so this doesn't block data collection. The new netlink plug-in reads very detailed routing statistics from the Linux kernel. The new snmp plug-in provides a generic interface to query remove hosts using SNMP.
Release Notes: The plugin architecture has been changed to move more functionality out of the daemon and into plugins. The network code has been improved to be smaller, more flexible, and forward compatible. A plugin for Nagios allows the use of collected values for monitoring purposes. Interfaces for external plugins have been added, such as a UNIX domain socket, the execution of arbitary binaries and scripts, and an experimental Perl plugin that is basically the equivalent to Apache's mod_perl. New statistics plugins are the entropy, irq, iptables, and nut plugins.
