Fast Poller Issues

[cwalton]

Perhaps I'm just being dumb, but I believe that I've executed the instructions correctly and am still unable to get this working. I am going to try to give a lot of detail in this post, so it may run long. Additionally, I was working on this all day yesterday () and looked for any possible information before posting.

Operating System: Windows Server 2003 Enterprise
Specs: Dual P3 Xeon 1.3GHz, 4GB RAM
Webserver: IIS6
Cacti: 8.6i
Cactid: 8.6i
MySQL: Ver 14.12 Dist 5.0.27
PHP: 5.1.4 (cli) (built: May 4 2006)
RRDTool (CYGWIN version): 1.2.15
Net-SNMP: 5.3.1
Cygwin (cygwin1.dll version): 1005.23.0.0

I used BSOD's instruction set when doing the installation, the same instructions that assisted with my current functional installation (thanks!). I applied the fast polling patch, then pointed my browser to the site and performed the initial config (paths, etc).

Before performing the changes listed in the fast-poller readme, I added a couple simple devices (localhost, 72-port switch, 24-port switch; using only CPU and Interface queries) and tested it. Worked like a charm.

I performed the updates listed in the fast-poller readme. Before adding a test device, I performed another manual poll with the existing devices. This poll worked fine.

I added another simple device (48-port switch) and created graphs using the 1-minute template. The graphs were created as normal.

I then perfomed a manual poll and the results made me sad. The poller ran without errors, listing everything as normal except for: DataSources:0 RRDsProcessed:0.

I ran the poller again, thinking it may have been a fluke. This time everything was normal except for: DataSources:40 RRDsProcessed:20.

The next run yielded DataSources:41 RRDsProcessed:21.

I turned on super-cool debug logging (the log is attached). Upon not seeing any errors, I checked the RRA directory. All the RRAs for my original devices are there. However, there are no RRAs for the 48-port switch. Here is a snapshot of 2 data source debugs:

RRA Exists:

Code: Select all

e:/monitoring/site-1/rrdtool/rrdtool.exe create \

--step 300  \

I also found that doing the following "fixes" the graphing of the existing devices:
1) Delete the device(s) using fast-polling
2) Set the poller back to 5-minute intervals
3) Poll once, you still get wacky results (fewer DataSources/RRDs than there should be)
4) Poll twice, everything is back to normal



Any assistance will be greatly appreciated.

Update:

The wacky manual poll behavior (DS:0 RRD:0) occurs if the poller is set to 1 minute, regardless of whether or not there are any devices utilizing the 1 minute templates.

The first poll after it is set to 1 minute yields normal results, the second poll yields 0/0.

This is why one should always set up plain old vanalli cacti BEFORE playing with any sort of add-on, etc. to make sure everything works.

If you go back to plain cacti, does polling stuff work fine? If so, then its something broken about the 1 min polling patch and you should post in http://forums.cacti.net/viewtopic.php?t=16482.

Indeed the plain vanilla install works fine. I have a regular test install and a modded production install running already.

I neglected to mention in my OP that yesterday I tried the plane-jane deal and it was smooth.

[cwalton]

Fixed it! Yay! It wasn't elegant, but I simply erased the installation and started from scratch with a new DB. It works now

Thanks for the quick reply, BSOD.
