rrdproxy

Cacti RRD Proxy is a standalone proxy interface to Tobi Oetiker's great RRDTool. Main focus of this project is to allow a relocation of RRD files including data replication, support of Cacti Boost as well as the RRDcached daemon. RRDtool proxy allows to split Cacti into more different components (for really big installations) without the need for NFS. And it will be natively supported by the upcoming major release 1.0 of Cacti.

Due the fact that we are talking about critical file transactions RRDtool proxy only supports high encrypted connections (RSA2048 + AES192) with continuously changing keys between the proxy and registered clients / proxies.

Over a local service port administrators are able to access a separate command line interface that allows to configure and debug the proxy.

Requirements

RRD proxy should be able to run on any Unix-based operating system with the following requirements:

• PHP 5.4+, 7.1+ recommended
• RRDTool 1.5+, 1.6+ recommended

PHP Must also be compiled as a standalone CLI binary including modules for SOCKETS, POSIX, PCNTL, GNU GMP and ZLIB.

Usage

At the first go you will automatically run through a setup routine (-w).

 php rrdtool-proxy.php --help

Missing features

• Data replication has been completed to 95%, but is still not ready
• NET-SNMP pass persistent daemon and MIB needs to written to make proxy stats available through SNMP
