You need to install librrd first to be able to use
PECL/rrd. Most common option is using of librrd-dev package from
your favourite linux distro. PECL/rrd is tested with librrd 1.4.3,
older or newer versions might or might not work for you. PECL/rrd
installation is tested with PHP 5.3.2 or newer.
Warning
Librrd and hence extension itself aren’t mostly
thread safe. There are many global and shared states in librrd. It
can be dangerous use this extension in multi threaded environments
like Apache2 mpm worker. If there are many parallel requests, one
request can change some global librrd state of other runnig
requests.
