HELP on broken graphs -nan inpit and output

[gfalconx]

Hi Cacti Masters,

I'm kinda new cacti and I am currently having issues with our ASR 920s. Our setup is that we have a cacti dedicated for DC infra and cacti dedicated for Branch locations that are both patched and now running version 1.2.21.
I have noticed that after the upgrade, our ASR 920s graphs are no longer working as both input and output are shown as -nan.

I have done the following:

- Re index the graphs
- Deleted the related hostnames and recreated it
- Used a different template
- Rebooted cacti dc server
- Tried creating graphs on our cacti branch that are running same version 1.2.21. (working)
- Export the working template tested on cacti branch and imported it on our DC cacti (still not working)

If we try to do a Realtime graph its working! it's not showing -nan on both input and output.

None of these worked and Im kinda desperate now. Can you please help and let me know your thoughts?

Since you are new to things, just upgrade to the 1.2.x branch of cacti. Should be release very shortly, then run the poller_reindex_hosts.php. Upgrading is simple. Assuming you have git installed already, it's done like this (assuming the web root is /var/www/html).

Put this script in /var/www/html and make it executable and then run it.

Code: Select all

#!/bin/sh
rm -rf cacti-develop
git clone -b 1.2.x https://github.com/cacti/cacti.git cacti-develop
/bin/cp -rpf cacti-develop/* cacti
chown -R apache:apache cacti
rm -rf cacti-develop

Once you run it, either attempt to login to Cacti or hit the F5 button to refresh the page and follow the upgrade instructions. It's that easy.

Thanks mate the upgrades are set by our server team and they do patching. What amazes me on this issue is that both cacti's we have, have the same version. It works on our cacti used for branches but it's not working on the cacti that we use for our DC gears.
