selinux or apparmor?
Try to disable it

[habeebth]

selinux is already disabled, however the apparmor was running, disabled it.

waiting for the new data

[habeebth]

Still no change... It is still not plotting any graphs.

My spine was 1.2.19, updated to 1.2.27.

[habeebth]

I think i have managed to fix this by reimporting the rrd files again from old server, will update the final result soon.

Did any paths change? Check the poller cache. Also, if boost is off, disable cactid and run poller.php with the force option from the command line.

If boost is on, make sure data is accumulating in the table poller_output_boost.

Thanks Macan & TheWitness.

After importing new rrd file,s it started plotting graphs. Meanwhile i want to know the compatible "realtime" plugin for the latest version 1.2.27.

I don't see any downloadable link.

Realtime is in the base for several years.

[habeebth]

Thanks TheWitness.

I got it working. I have one issue where the "time graph view" plotting duplicate graph lines instead of just two inbound & outbound.

Graph settings:
Inbound Green (Line1-Max & Area - Average)
Outbound Blue (Line1-Max)

However we see the additional graph for inbound traffic on daily, weekly & monthly graphs. An Additional line for inbound traffic.

Screenshot is attached.

expected graph out put screenshot is attached

Make sure graphs are 64 bit. Also, in realtime, if you poll too often, you will get these choppy graphs as not all manufactures provide live data. Instead it's cached on the switch or router, which means if you poll to frequently, the graph will get those chopps.

Consult with you device manufacturer for that cache interval. With Net-SNMP, it used to be 15 seconds.
