Some graphs not showing disk utilization

Post by aengel »

Hello,

I am running into the issue of some graphs not showing hard drive utilization. It will show blue for the total space but the 'used space' will not show up on the graphs. When I use realtime on those graphs they display correctly. I tried deleting all graphs associated with the hosts in question and recreating them; some hosts start working but others do not.

I am running Cacti 0.8.7g on CentOS 5.6 64 bit. CMD.php runs in about 20 seconds with 10 concurrent poller processes. Debug doesn't show too much information about these particular hosts. The hosts being graphed are mostly Windows Server 2003 and a few Server 2008 hosts in there.

Thank you for any input!

Here is an example of that same host when looking at realtime. Weird issue now is after running realtime for a minute, some usage data starts to show up on the main graph, not sure if it will go back down to zero but I will keep watching.

The main graph did start to show some usage data but went back down to zero after realtime was closed.

I tried deleting all data sources which worked for a couple of the servers but not all. This morning I deleted the HOST and all DATA SOURCES associated. Now the graphs are working as expected for hard drive space.

Is there a way around deleting the HOST if this happens again?

Always when I see windows disk usage issues, I recommend to increase timeout to e.g. 2000 ms. Windows SNMP is way sloooow

Re-adding the windows hosts worked and I have not had any issues since. I just went through all the windows hosts and set the SNMP timeout for 2000 so hopefully everything will be solid. Thank you!
