I configured the munin on Centos 7 and it is configured but the graph is not creating when I am going to check the current day graph it is not showing anything. I checked the log file
munin-cgi-graph.log it is showing
Could not draw graph "/var/lib/munin/cgi-tmp/munin-cgi-graph/localhost/localhost/processes-pinpoint=1483825506,1483933506.png?&lower_limit=&upper_limit=&size_x=800&size_y=400"
I am using apache and munin 2.0.28. If anyone knows what is the problem please help. I am attaching the error screenshots:
