error opening the file: tmp/791.png

[milleryuan]

I installed the new version(nmidCreatePDF_v0.3a2.tgz) today, my Cacti version is 0.87b, I have two question:
1.I got a PDF file but have no graph show there, it's "error opening the file: tmp/791.png", I try to use "create_image.php 791 0 1237298394 1237384794 100 800 > tmp/791.png " to create a graph by manual, it's succeed, and it can be show in IE, Could you please help me to check it?

2.I can used "submit" button in the first page(graph_view.php), but if I click my graph going to second page(graph.php), I can see that check box only, and the submit button missed. Is it by design?

Thanks
Miller

is the tmp dir writeable by apache ? try

Code: Select all

cd /path/to/cacti/plugins/nmidCreatePDF
chown root.apache tmp/
chmod 665 tmp/

it may be that it is wwwrun in your case instead of apache ...

If you extract the plugin with

Code: Select all

tar -xzvpf nmidCreatePDF_v0.3a2.tgz

it should set the permissions correctly ( -p does that ...)

It is by design. If you look at the roadmap for v0.4 you will see that it will be included there ( Feature #26 )
