). I've just installed freshly (new ubuntu server + the new cacti) the new 0.8.8a and wanted to install the discovery and weathermap plugins, so, I check the admin right as for the ancient versions, and there is no activation checkbox. So, as the 0.8.8 is supposed to integrate the plugins gestion, i can saw the plugin management in left side of the cacti for more details see the attached screen shot.please any one can tell me how to install the plugins to step by step.thanks
