|
|
The webserver where I run cacti on already has a user account/password setup in front of it, so having to login in twice to get to Cacti was being a PITA.
Turning off authentication in Cacti (see cacti/settings.php?tab=authentication, or the Authentication Tab in Configuration/Settings) means the weathermap would emit some weird messages and not work.
I found two files so far that needed to be fixed to make it work with no Cacti authentication

Odd problem here. If I run poller.php from the commandline, weathermap executes and runs properly. When I let poller.php run as a cron job, I get this:
06/29/2006 04:35:13 PM - WEATHERMAP: Poller[0] Weathermap 0.82 in da house

For what it's worth, I'm using cactid 0.8.6e with Cacti 0.8.6f
I'm running poller.php from the commandline as the same user with poller.php in its crontab, so permissions/paths/etc. should all be the same.
Any thoughts?
Thanks,

Ummmm. I don't see any error. That's exactly what you should get, assuming that DEBUG is on, and there is some more after that in the logs, too... |

Well, that's the problem.  DEBUG is on, and that's the last line in the log.

Aaah.. I see the problem now. It looks like someone else has written an HTML_ImageMap class, and submitted it to PEAR. If you don't need it for anything else, then the quick fix would be to uninstall the PEAR HTML_Imagemap class: | Code: |
pear uninstall HTML_ImageMap |
I'll have to change that classname in a new version, I guess.
Either that, or did you copy that class file from the weathermap folder in your /usr/share/pear? I don't actually see HTML_ImageMap on the PEAR site... |

That's not always true. On my FreeBSD systems, cron runs with a more restricted path than the regular shell. I think that's fairly common, too - man 5 crontab will confirm for you.
That said, there's only one external program that weathermap uses, and that's rrdtool, for which it gets the full path from Cacti. |

Once I noticed the error I copied the weathermap HTML_Imagemap class over the pear one but still error for some reason. There are no other weathermap references in a debug run of the cacti log either for some reason. I'll try moving the pear file and see what happens.
EDIT: That was the problem. I removed the class file from the pear folder and it works now. Thanks. |

I think the reason is that in some parts of Weathermap it uses require_once to load a class file only once. However, in some places (in the cacti-specific files) it uses the full path to the classes, but in others it uses the class name only, which would choose the PEAR copy. At that stage PHP can't tell that the two 'different' files should be treated as one for the require_once process. |

Hello!
I have installed 0.82 version and seems to run smoothly.
The only problem i have is that link status does not change.
Maybe it can't read from the corresponding rrd file.
Here is the output of debug in cacti.log file.

stelaras1,
NaN means that the information from those datasources isn't being read correctly by cacti. Verify that you can view the actual graphs for those items first, from the normal Graphs view in Cacti. |

That's true, but it also says
| Code: |
07/06/2006 02:57:03 PM - WEATHERMAP: Poller[0] ReadFromRRD: Our line is 1152186900: 0.0000000000e+00 8.5097513333e+03
|
which is means it should be returning (0,8.5K), not (0,0)
It's not that unusual to have the last line be a NaN, if the poller takes a long time to run, which is why it searches backwards for non-NaN lines.
That said, is it possible that your RRD uses DS names other than 'traffic_in' and 'traffic_out', stelaras1? It seems that your DS names are 'in' and 'out'. If they are, you'll need to change your TARGET line to TARGET blah.rrd:in:out.
There's already a fix in 0.9 to make this type of problem more obvious. |
