Alvarion Graphs Not showing up

northfieldwifi · Post by **northfieldwifi** » Mon Oct 19, 2009 6:09 pm

Hello,

We have imported some Alvarion AU and SU graphs for the VL line. We have added a device (AU) and the system reads the device, can tell uptime, software version and etc. But when we go to create a graph, the graphs seem to be broken.

Attached is an example of what we are running into.

Any help, would be greatly appreciated.

Here is another screen shot, it shows traffic is being graphed, just appears as though the graphs are broken......

Any suggestions on what to look into?

We have installed this version of Cacti on a Win2k3 Server with IIS 6.0. We ended up using the cacti-0.8.7e-1.931x86 Windows installer which does the entire process for you. Not sure if that info will help or not.

Any help would be greatly appreciated!

Thanks all!!

Ok, so more info to report. Looks like we need to do the following:

For you to actually get graph images, poller.php must run at least once so it can create .rrd files in Cacti's 'rra/' directory. Double check that you configured your /etc/crontab file to execute poller.php every five minutes. Also make sure that the user poller.php runs as has permission to create new files in Cacti's 'rra/' directory

How do we get the poller.php to run?

Ok even more info.

So we have done the following:

I just installed Cacti and all of my graphs appear as broken images.

For you to actually get graph images, poller.php must run at least once so it can create .rrd files in Cacti's 'rra/' directory. Double check that you configured your /etc/crontab file to execute poller.php every five minutes. Also make sure that the user poller.php runs as has permission to create new files in Cacti's 'rra/' directory.

If all of your settings appear correct, try running poller.php manually by cd'ing to Cacti's directory and typing:

shell> php poller.phpIf you have files in your 'rra/' directory, but your graphs still appear as broken images, you should enable graph debug mode see exactly why the graphs are not rendering. To do this go into Cacti, select Graph Management from the menu, select any graph listed, and select Turn On Graph Debug Mode.

Here is our Graph Debug.

RRDTool Says:

ERROR: invalid rpn expression in: a,8,*

Thoughts? (Sorry for all the posts, just want a history of where we started VS where we are.....)

That graph has no data source (and thus, rrd file) associated to it.

Aw, I see. So how do we change this so we do have data sources. The dropdowns have nothing populated in them to choose from.

northfieldwifi · Post by **northfieldwifi** » Tue Oct 20, 2009 10:08 am

Well I am getting somewhere with it, but hte graphs are still not showing. I even ran manually ran the scheduled tasks thinking maybe that would generate them. See screen shots below, Iam guessing I just have 1 small thing off.

JACKPOT. Got her working! Thanks for the help.

If I want to speed up the polling being done do I just change the scheduled task running on the server from 5 mins to 1 min?

Not exactly. There're several steps you need to go through to convert from 5 minute polling to 1 minute polling, as the data sources & RRD files need to be restructured for 1-minute polling. If you search the forums, there are a couple good guides on how to do it.

Is there anything we should be looking at in terms of the graphs not actually recording any data? Our graphs are now showing, but no data is being recorded........

northfieldwifi · Post by **northfieldwifi** » Tue Oct 20, 2009 10:45 am

We are getting graphs to work, but graphing is not working.

Change the cacti logging level to medium or higher. Then watch what the Alvarion AU and SU scripts/data sources are returning from the device. U is a lack of data.

northfieldwifi · Post by **northfieldwifi** » Thu Oct 22, 2009 8:23 am

Yes they are working, sorry. We were just not patient enough to let the data come in.

We are looking at needing a realtime graph. I see there is a realtime plugin, but our folder structure within Cacti does not have a plugin folder and that according to the directions of the realtime install is where we are to put the scripting for it.

Any newer versions of real time or a better walkthrough out there?
