Map generated only manually - SOLVED SEE PAGE 3

Post by tomate »

Hello,

When i generate the map manually using the "recalculate all maps now" button, all works fine.

But when it is done by cacti, stats on my links are only 0 and i have this in the logs :
11/27/2008 03:09:15 PM - WEATHERMAP: Poller[0] [Map 2] weathermap.conf: ReadData: LINK plop-new-IP-MPLS, target: /usr/share/cacti/site/rra/plup_traffic_in_1020.rrd on config line 296 had no valid data, according to WeatherMapDataSource_rrd
any idea ?

Turn on DEBUG in Cacti, and let it run for one cycle.

Look in the cacti.log file. You should get a lot more information about what is going on.

Also, check permissions. When you do 'Recalculate Now', it runs as the Apache user, while the poller runs as 'cacti'.
Weathermap 0.98a is out! & QuickTree 1.0. Superlinks is over there now (and built-in to Cacti 1.x).
Some Other Cacti tweaks, including strip-graphs, icons and snmp/netflow stuff.

I run cacti with the root user (for ICMP ping)

i have enabled debug, i will paste the result

well, i have a very huge amount of debug lines :/

is it possible that the problem comes from the fact in my graphs i have some '/' or '-' in titles or legends ?

i read something about escaping some caracters on google but not directly when using weathermap via cacti

No, I don't think so.

Look for your original error (about no valid data), and then look above that in the logs. You should get some info about WHY it thinks there is invalid data.

No... in the DEBUG section of the log, there should be something like 20 lines of log per link. It will show what rrdtool command is being run, the output, whether it thinks any of the output is useful, whether the rrd file exists, what value it's going to return etc etc.

That's weird. Can you get a DEBUG log from the manual run too?

In the one that you posted, rrdtool is producing localised numbers: 4,8368619045e+01 (, instead of .). I've never seen it do that before.

I'd like to see if the manual run has the same style of numbers, or 4.8368619045e+01 instead.

OK, well I guess it uses a '.' because it's working :-)

The fix will be in lib/datasources/WeatherMapDataSource_rrd.php

on line 266 and 270 (roughly), change the preg_match() lines to say

/^\-?\d+(,\.)?\d*e?[+-]?\d*:?$/i

instead of
/^\-?\d+\.?\d*e?[+-]?\d*:?$/i

so that it will match a , or a .
