I’m having a strange issue on Centos 7 and Cacti 0.8.8b. I have the ss_get_by_ssh.php script working (from command line) but the cacti graphs are blank. Here’s output from the script:

[root@ip-x.x.x.x ~]# sudo -u cacti php /usr/share/cacti/scripts/ss_get_by_ssh.php --type proc_stat --host y.y.y.y --items gw,gx,gy,gz
gw:2561826 gx:13105 gy:5533113 gz:2389303747

Every single Percona graph on Cacti is a broken image. Any ideas?

Also, my logs are filled with the following: [TABLE]

Disregard this post. I ended up writing my own python scripts to scrape and parse the nginx server-status page and wrote my own data inputs, data and graph templates. I did manage to find issues with the Percona supplied ss_get_by_ssh.php scripts; the main one a couple of unnecessary single quotes in the script that was fudging the results… sometimes it’s easier just to do things yourself than troubleshoot someone else’s work.
