Renaming hosts does not change graphs on rrdcache server

Hi there,

I am running a separate server for my rrdcache from my librenms server. This all works and graphs are updated or created as expected.

The issue I am having is when I rename a host using the renamehost.php script on the cli, the rrd’s on the rrdcache server are not renamed and I lose all history.

rrdcache server is version 1.6.0

librenms config.php has $config[‘rrdtool_version’] = ‘1.6.0’;

Any ideas where I should look?
