Start Rrd files not updating

Rrd files not updating

In reply to your comment that file/directory ownership/permissions may be the issue, I will share what I have found to be useful for my Cacti installations that run on Open BSD (aka, your placement and syntax may vary with other systems): chown -R www:www /var/www/htdocs/* echo 'web directories reset to www:www ownership' chmod -R 777 /var/www/htdocs/cacti/plugins/* chmod -R 777 /var/www/htdocs/cacti/log/* chmod -R 777 /var/www/htdocs/cacti/rra/* echo 'cacti plugin, log, and rra directories set to full r,w,x' I use weathermaps heavily in cacti and often find myself having to reset permissions over and over throughout and this has save me the headache of thinking about it constantly.

By default, the update function expects its data input in the order the data sources are defined in the RRD, excluding any COMPUTE data sources (i.e.

if the third data source DST is COMPUTE, the third input value will be mapped to the fourth data source in the RRD and so on).

rrdtool filename [--template|-t ds-name[:ds-name]...] [--skip-past-updates|-s] [--daemon|-d address] [--] N:value[:value]... The data is time aligned (interpolated) according to the properties of the RRD to which the data is written.

Are permissions for the file/directory set properly to allow for this?

I successfully graphed CPU/Interface traffic, but got blank graphs like when it comes to Memory/Temperature monitoring.

The problem/bug is actually archived here, however this post didn't help.

It also occurs every time a new graph is generated, such as when looking at a service graph in the web interface.
