Ping Latency graph no data

Operating System: Server 2008 R2
Webserver: IIS 7.5
Cacti: 0.8.8a
Spine: 0.8.8a
MySQL: 5.5.27
PHP: 5.3.17

Plugin Architecture:

I have installed Cacti using the windows installer; I did not see any errors in the install log file. All SNMP graphs are showing data correctly, ping latency graph is not showing any data. I am new to Cacti and need some help. I have seen the exact question asked on the site but I have never seen the answer to the issue. Here are some screenshots. From what I see, it doesn't appear to be an NTFS permission either.

Attachment 1 shows Graph debug
Attachment 2 shows Data source debug
Attachment 3 shows ping latency displayed in the device properties page.

And here is the Cacti install log and the CSV ouput for the graph, and the cacti log

It's refreshing when someone reads forum stickies and their posts contain lots of helpful details

If you change the cacti logging level to debug, you'll find out why DS[8] (which is clickable -- should likely be the ping script) is failing to properly run.

Thanks for the reply. So, here is the log after turning on the poller debug. I don't really understand all it says. And during more troubleshooting, I ended up deleting the graph and re-adding it, so now the it says DS[11] instead of [8], just so no one thinks I'm looking at something different now. When I click on [11] it shows the data source debug(second screenshot).

if you manually run that perl ping command, does it work?

With newer Windows OS's, depending on the ping method used, it needs admin permissions to create the raw socket. The Cacti Task might need to be ran as admin with elevated permissions.

If you're really interested in graphing ping response, look at the advanced ping template (which mimics smokeping-like output) in the script forum.

No, it doesn't, when I run the ping.pl script form the command prompt, I get a U.
I'll see if I can find the advanced ping and get that working.

Hi all,
I'm having the same problem.
I can manually run the script from command line (got positive output) but Cacti log shows as below:
05/28/2015 12:41:03 PM - POLLER: Poller[0] NOTE: There are no items in your poller for this polling cycle!
05/28/2015 12:41:02 PM - POLLER: Poller[0] NOTE: There are no items in your poller for this polling cycle!
05/28/2015 12:41:02 PM - POLLER: Poller[0] CACTI2RRD: C:/rrdtool/rrdtool.exe update C:\Apache2\htdocs\cacti\rra\\11.rrd --template VG-01 1432791662:U
05/28/2015 12:41:02 PM - CMDPHP: Poller[0] Time: 0.0098 s, Theads: N/A, Hosts: 0

Please advise what could be the problem and what should I do. Thank you very much.
Other information:
- OS: Windows Server 2012 R2
- Cacti
- Apache comes with Cacti.
- Other graphs monitoring Cisco Routers are working fine.
- The rrd for the script is presented in rra folder.
- I checked process monitor and no Access Denied errors found.

you should've created your own topic as it has nothing to do with this post.

VG-01.pl, output: U

means the script isnt returning data back to Cacti. Validate the cacti scheduled task has permissions to execute that script (manually verify by running it AS the task user account).
