On this page you can change general settings for the collectd daemon. Hostname Base Directory Directory for sub-configurations Directory for collectd plugins Used PID file Datasets definition file Data collection interval Seconds Number of threads for data collection Try to lookup fully qualified hostname CPU Plugin Configuration The cpu plugin collects basic statistics about the processor usage. Enable this plugin CSV Plugin Configuration The csv plugin stores collected data in csv file format for further processing by external programs. Enable this plugin Storage directory for the csv files Store data values as rates instead of absolute values DF Plugin Configuration The df plugin collects statistics about the disk space usage on different devices, mount points or filesystem types. Enable this plugin Monitor devices multiple separated by space Monitor mount points multiple separated by space Monitor filesystem types multiple separated by space Monitor all except selected ones Disk Plugin Configuration The disk plugin collects detailled usage statistics for selected partitions or whole disks. Enable this plugin Monitor disks and partitions multiple separated by space Monitor all except selected ones DNS Plugin Configuration The dns plugin collects detailled statistics about dns related traffic on selected interfaces. Enable this plugin Monitor interfaces multiple separated by space Ignore source addresses multiple separated by space E-Mail Plugin Configuration The email plugin creates a unix socket which can be used to transmit email-statistics to a running collectd daemon. This plugin is primarily intended to be used in conjunction with Mail::SpamAssasin::Plugin::Collectd but can be used in other ways as well. Enable this plugin Filepath of the unix socket Group ownership of the unix socket group name File permissions of the unix socket octal Maximum allowed connections Exec Plugin Configuration The exec plugin starts external commands to read values from or to notify external processes when certain threshold values have been reached. Enable this plugin Add command for reading values Here you can define external commands which will be started by collectd in order to read certain values. The values will be read from stdout. Commandline Run as user Run as group Add notification command Here you can define external commands which will be started by collectd when certain threshold values have been reached. The values leading to invokation will be feeded to the the called programs stdin. Commandline Run as user Run as group Interface Plugin Configuration The interface plugin collects traffic statistics on selected interfaces. Enable this plugin Monitor interfaces hold Ctrl while clicking to select multiple interfaces Monitor all except selected ones Iptables Plugin Configuration The iptables plugin will monitor selected firewall rules and collect informations about processed bytes and packets per rule. Enable this plugin Add matching rule Here you can define various criteria by which the monitored iptables rules are selected. Name of the rule max. 16 chars Table Chain Action (target) Network protocol Source ip range CIDR notation Destination ip range CIDR notation Incoming interface e.g. br-lan Outgoing interface e.g. br-ff Options e.g. reject-with tcp-reset IRQ Plugin Configuration The irq plugin will monitor the rate of issues per second for each selected interrupt. If no interrupt is selected then all interrupts are monitored. Enable this plugin Monitor interrupts multiple separated by space Monitor all except selected ones Load Plugin Configuration The load plugin collects statistics about the general system load. Enable this plugin Netlink Plugin Configuration The netlink plugin collects extended informations like qdisc-, class- and filter-statistics for selected interfaces. Enable this plugin Basic monitoring hold Ctrl while clicking to select multiple interfaces Verbose monitoring hold Ctrl while clicking to select multiple interfaces Qdisc monitoring hold Ctrl while clicking to select multiple interfaces Shaping class monitoring hold Ctrl while clicking to select multiple interfaces Filter class monitoring hold Ctrl while clicking to select multiple interfaces Network Plugin Configuration The network plugin provides network based communication between different collectd instances. Collectd can operate both in client and server mode. In client mode locally collected date is transferred to a collectd server instance, in server mode the local instance receives data from other hosts. Enable this plugin Listener interfaces This section defines on which interfaces collectd will wait for incoming connections. Listen host host-, ip- or ip6 address Listen port 0 - 65535 server interfaces This section defines to which servers the locally collected data is sent to. Server host host-, ip- or ip6 address Server port 0 - 65535 TTL for network packets 0 - 255 Forwarding between listen and server addresses Cache flush interval seconds Ping Plugin Configuration The ping plugin will send icmp echo replies to selected hosts and measure the roundtrip time for each host. Enable this plugin Monitor hosts multiple separated by space TTL for ping packets 0 - 255 Processes Plugin Configuration The processes plugin collects informations like cpu time, page faults and memory usage of selected processes. Enable this plugin Monitor processes multiple separated by space RRDTool Plugin Configuration The rrdtool plugin stores the collected data in rrd database files, the foundation of the diagrams.

Warning: Setting the wrong values will result in a very high memory consumption in the temporary directory. This can render the device unusable! Enable this plugin Storage directory RRD step interval seconds RRD heart beat interval seconds Only create average RRAs reduces rrd size Stored timespans seconds; multiple separated by space Rows per RRA RRD XFiles Factor Cache collected data for seconds Flush cache after seconds TCPConns Plugin Configuration The tcpconns plugin collects informations about open tcp connections on selected ports. Enable this plugin Monitor all local listen ports Monitor local ports 0 - 65535; multiple separated by space Monitor remote ports 0 - 65535; multiple separated by space Unixsock Plugin Configuration The unixsock plugin creates a unix socket which can be used to read collected data from a running collectd instance. Enable this plugin Filepath of the unix socket Group ownership of the unix socket group name File permissions of the unix socket octal Wireless Plugin Configuration The wireless plugin collects statistics about wireless signal strength, noise and quality.
