These devices have "SNMP - Interface Statistics" data sources and other data sources.I discovered that the realtime graph view functionality still tries to reach the devices for the "SNMP - Interface Statistics" data sources using the old hostname. What doesnt graph is hard drive usage (hdtotal/hdfreespace) on windows or linux boxes Windows servers will only graph network stats not hd/cpu. I followed the upgrade instructions here - Cacti Server; Linux Red Hat server RHEL4connect to mysql Not using custom scripts basically inbuilt server (index) scripts.I have confirmed that the OID in the Server script directory are correct.Went through the trouble shooting steps here - Linux server are ok with recording and displaying cpu/network but not hard drive data.
Check out the book below for more tools to use for Linux server administration.Go to Console: Click the console tab at the top of the browser 3. Change Log Level: As you can see in the example above click the Poller Logging Level drop down and switch to LOW.Visit Settings: In the left nav near the bottom click on Settings. This will show only statistics and errors as described in the drop down.I realise this post is a bit all over the place, but new to cacti and want to fix these issues. Even if it is just to set up a windows server monitoring graph.I recently upgraded my 0.8.7g Cacti installation to 1.1.7 and now to 1.1.9. Then I changed the "hostname" attribute of a few devices on the Cacti 1.1.9 installation.
