# rrdcollect(8)

## NAME

RRDcollect  --  Round-Robin Database Collecting Daemon.

## SYNOPSIS

**rrdcollect** \[*option*\]...

## DESCRIPTION

The **rrdcollect** daemon is responsible for fetching statistical data from various soures (listed in **rrdcollect.conf**), typically files under **/proc/** directory.  It periodically reads them and searches for patterns from configuration file. Values are then stored inside **rrdtool**'s *.rrd* files.

## OPTIONS

RRDcollect follows the usual GNU command line syntax, with long options starting with two dashes (\`-').

### General options

- **-c** *file*

  - **--config=***file*

  Specifies which *file* should be read instead of default config file.

- **-n**

  - **--no-fork**

  Program will not fork.  Very useful when testing or debugging.

- **-v**

  - **--verbose**

  Increase verbosity.  This option also implies **--no-fork**, since you probably don't want RRDcollect in daemon mode trashing your terminal.

### RRD update options

- **-o** *file*

  - **--output=***file*

  Specifies *file* to which [*rrdtool*(1)](/rrdtool/1.md)-style commands should be written.  If *file* you specify is \`**-**' (hyphen), then commans are written to standard output (this case implies **--no-fork**).

- **-p**

  - **--pipe**

  - **--pipe=***program*

  When this option is used, RRDcollect will open pipe to [*rrdtool*(1)](/rrdtool/1.md) program and send it update commands.  If you don't give *program*, the compiled-in default is assumed (either \`**rrdtool - \>/dev/null**' or full path to [*rrdtool*(1)](/rrdtool/1.md) binary).  The *program* option can be specified as a full path or just a command name, in the latter case the program should reside on **PATH**.

If no RRD update option is given, RRDcollect uses internal librrd routines (the preferred mode of operation).  If RRDcollect is not compiled with librrd, then it will fall back to pipe-mode.

### Help and information

- **-V**

  - **--version**

  Display RRDcollect's version, compile-time options and license.

- **-h**

  - **--help**

  Show summary of options.

- **--usage**

  Show short usage information.

## FILES

**/etc/rrdcollect.conf**

## SEE ALSO

[*rrdcollect.conf*(5)](/rrdcollect.conf/5.md), [*rrdtool*(1)](/rrdtool/1.md), [*pcre*(3)](/pcre/3.md)

## BUGS

Hopefully not many...
