<div>You can do this in several ways; Bernard has already mentioned RRD server, but (with RRDTool 1.4.x) you can also use rrdcached, the caching daemon, to provide remote access over the network to a subset of commands. I've been playing with the quite a bit recently and it has a whole load of useful possibilities.</div>
<div> </div>
<div>With rrdcached you can run update and fetch over the network, and graph can run locally but pull the date from a remote rrdcached. If you get the current trunk (beta) version of rrdtool 1.4 then you can also run first, last, info, and create over the network as well.</div>
<div> </div>
<div>In your setup, if you put the rrdcached between cacti and rrdtool using a UNIX-domain socket (by setting the RRDCACHED_ADDRESS before starting Cacti) then it should continue to run as normal but will be a bit more efficient on writes; however you can also have rrdcached listen on a TCP socket simultaneously allowing your remote Windows box to query the database via this. Having the local Cacti write via a unix socket rather than TCP is better as it is (1) faster and (2) can fall back to using direct mode for commands not yet supported by rrdcached.</div>
<div> </div>
<div>For security, you can set rrdcached command line options to prevent the remote Windows box from doing anything other than first/last/info/fetch, and use tcpwrappers or local firewall to restrict remote connections.</div>

<div class="post-text">Hi All, is it possible to connect access an RRD (e.g. Cacti RRD) from a different machine over the network? (e.g. connect to the RRDTool over TCP or something)<br><br><br><br>More context: We have Cacti (RRD backend) deployed on a linux machine and want to be able to query the Cacti RRD database from a windows machine. However, we don't know if this is possible without us writing custom server code to serve as the interface to the linux machine's RRDTool.<br><br><br>Thank you all for your time.<br><br><br>Miguel</div></div></div></body></html>
