Weathermap - Link bandwidth not displayed

[Hyland]

I am running Cacti version 0.8.6h on a Win2k box and am having problems with the weathermap plugin. Everything works with the plugin except the link bandwidth is not being displayed. My Cacti logs show the following entry:

WEATHERMAP: Poller[0] ReadData: Link Architect-Oracle, target: C:/Inetpub/wwwroot/cacti/rra/architect_traffic_in_1599.rrd on config line 47 had no valid data

I am assuming there is something wrong with the path to the .rrd files but I have tried all combinations of paths and none have worked. I have also re-created the data source that this link pulls data from and this has not helped. I updated the version of rrdtool to 1.2.10 but I starting having issues with Cacti then, so I rolled back that update.

Using:
IIS 5
MySQL 4.1
PHP 4
Cacti 0.8.6h
rrd 1.0.49

Any suggestions would be appreciated.

Thanks.

It's not the path - you would get a different error then - "Target $target doesn't exist. Is it a file?"

Is it just this one link?

Turning on DEBUG logging in Cacti for one poller cycle might give you more of a clue.

[Hyland]

I only have one link created while I am testing the plugin. I have created another one and am getting the same results. I turned on the Debug logging in Cacti and have been looking through the logs.

Does the Data Source - Output Type ID setting make a difference to the weathermap plugin? All of my Data Sources are set to In/Out Bytes with Total Bandwidth. However for the Data Sources that I am trying to create the weathermap links for I have tried all different settings. (In/Out Bytes, In/Out Bits)

Also does the Bandwidth setting in the weathermap config matter? I have tried 100M, 1000M, 100000000.

Here are some of the Debug logs.

I think that your rrdtool somehow produces slightly different output to the normal one. Weathermap sees this -1.#IND000000e+000 as a valid number somehow, whereas I think it's really a NaN/Inf type of value. I'll try and work on a solution today, if I get a chance. Did you compile rrdtool yourself or is it from somewhere unusual?

Edit: One thing to try, from a quick look... in Weathermap.class.php, somewhere around line 1722, there is:

Code: Select all

if (trim($col) != '' && !preg_match('/\d+\.?\d*e?[+-]?\d*:?/i', $col))

try changing that to

Code: Select all

if (trim($col) != '' && !preg_match('/^\d+\.?\d*e?[+-]?\d*:?$/i', $col))

[Hyland]

The rrdtool I am using came from rrdtool.org and I am using the rrdtool.exe that was in the zip file. I am not compiling this on my own.

I edited the Weathermap.class.php file as you suggested and it did not solve the problem but the logs did change. Here are some of the logs:

Thanks for your help.

Disregard my last message. Right after I posted the message the weathermap refreshed and and the links now show bandwidth.

Thanks for all you help.

This is the sort of overview of the network I have been looking for.

Cool. I'll make that modfication in the next release.
