About
-----
* collectd is able to collect the following data:
+ - Apache server utilization
+ (Number of bytes transfered, number of requests handled and detailed
+ scoreboard statistics)
+
+ - APC UPS Daemon
+ (UPS charge, load, input/output/battery voltage, etc)
+
+ - Apple Sensors
+ (Temperature, fanspeed and voltage sensors of apple computers)
+
+ - Battery
+ (Charge, current and charge of ACPI and PMU based batteries)
+
- CPU utilization
(Time spent in system, user, nice and idle)
- Disk utilization
(Sectors read/written, number of read/write actions, time spent doing IO)
+ - DNS traffic
+ (query types, response codes, opcodes and traffic)
+
+ - Email statistics
+ (count, traffic, spam scores and checks)
+
- Harddisk temperatures
(Uhm, yeah, temperature of harddisks that is ;)
- System load
(Load average over the last 1, 5 and 15 minutes)
+ - mbmon - motherboard monitoring
+ (temperature, fanspeed and voltage information)
+
- Memory utilization
(Memory occupied by running processes, page cache, buffer cache and free)
+ - Multimeter
+ (Information provided by serial multimeters, such as the «Metex M-4650CR»)
+
- MySQL server statistics
(Commands issued, handlers triggered, thread usage, query cache
utilization and traffic sent/received)
- NFS Procedures
(Which NFS command were called how often. Only NFSv2 and NFSv3 right now)
+ - NTP Daemon
+ (Local clock drift, offset to peers, etc)
+
- Ping latency
(Time to reach the default gateway or another given host)
- Process counts
(Number of running, sleeping, zombie, ... processes)
+ - Sensors
+ (lm_sensors voltages, temperatures and fan rotation speeds)
+
- Serial
(RX and TX of serial interfaces)
- - Sensors
- (System temperatured and fan rotation speeds)
-
- Swap
(Pages swapped out onto harddisk or whatever is called `swap' by the OS..)
- VServer
(System ressources used by vservers)
+ - Wireless
+ (Link quality of wireless cards)
+
* Performance: Running as a daemon collectd doesn't spend much time in
startup. Since collectd links against libping, librrd and libsensors it
doesn't need to start any other processes.
own experiments.. Some of them require the `RRDs' Perl module.
(`librrds-perl' on Debian)
- * The RRD-files that collectd creates hold the following data. Use ``rrdtool
- resize'' if you want to cover longer/shorter periods of time.
-
- Resolution | Data points | Timespan
- -----------+-------------+----------
- 60 seconds | 1500 | 25 hours
- 30 minutes | 1680 | 35 days
- 6 hours | 1520 | 380 days
+ * The RRAs of the automatically created RRD files depend on the `step'
+ and `heartbeat' settings given on compile time. For a list of the
+ default RRAs take a look in the collectd(1) manpage.
Prerequisites
* Usual suspects: C compiler, linker, preprocessor, make, ...
- * rrdtool (headers and library; rrdtool 1.0 and 1.2 both work fine)
+ * rrdtool (optional; headers and library; rrdtool 1.0 and 1.2 both work fine)
If built without `librrd' the resulting binary will be `client only', i.e.
will send it's values via multicast and not create any RRD files itself.
+ Alternatively you can chose to write CSV-files (Comma Seperated Values)
+ instead.
* libmysqlclient (optional)
* lm-sensors (optional)
* libstatgrab may be used to collect statistics on systems other than Linux
- and/or Solaris. Note that CPU- and disk-statistics, while being provided by
- this library, are not supported in collectd right now..
+ and/or Solaris. Note that CPU- and disk-statistics, while being provided

<http://www.i-scream.org/libstatgrab/>
+ * libcurl (optional)
+ If you want to use the `apache' plugin
+
+ * librt, libsocket, libkstat, libdevinfo
+ Various standard Solaris libraries which provide system functions.
+
+ * libpthread (optional)
+ For parallelization, especially for plugins that communicate with the
+ outside, e. g. with a socket.
+
+ * CoreFoundation.framework and IOKit.framework
+ For copiling on darwin in general and the `apple_sensors' plugin in
+ particular.
