[SOLVED] Error on PNG files (error in Weathermap.class.php)

[Livio Zanol]

Hi,

I'm getting an error while trying to generate de PNG files.

The error is

Code: Select all

Notice: Undefined index:  traffic_in in /var/www/weathermap/Weathermap.class.php
 on line 1762

Notice: Undefined index:  traffic_out in /var/www/weathermap/Weathermap.class.ph
p on line 1763

The error occurs for all links.

The png is generated but no link activity is shown on the map.

I'm using MRTG to generate the rrd files (using routers2.cgi to monitor links), and have a "standalone" weathermap instalation.

Here is the DEBUG:

I'm using MRTG to generate the rrd files (using routers2.cgi to monitor links), and have a "standalone" weathermap instalation.

Here is the DEBUG:

Code: Select all

ReadFromRRD: Target DS names are traffic_in and traffic_out
 (timestamp    ds0               ds1
)

Any clues?

Yep. If you are using MRTG, then you need to specify DS names in your TARGET lines. The default ones are for Cacti (traffic_in, traffic_out).
Try:

Code: Select all

TARGET /var/rrdtool/detran-rt2_22.rrd:ds0:ds1

This error is somewhat clearer in the next release.

I have specified the ds0 and ds1 just like you've said...
The Bandwidth limit is 64K and I'm having about 50bps for in_traffic and 40bps for out_traffic, but weathermap gave me 3000%. What's wrong?

Clipped 3276.26077537% to 100%
Clipped 862.47497145% to 100%

Can you post a piece of the config (one LINK section) and the output of --debug?

[Livio Zanol]

Sorry, I've made a mistake on the rrdtool file

It works like you've said! Thank you!

EDIT: Ow!!!!
Real Time support?
hehehehe
