I'm having the same problem as qwertz. My processes are increasing indefinitely.



This has happened to me as well - any solution? I turned it off last night and the process numbers have flat lined. Certainly a problem with this script.

I really wouldn't mind using this script, but it doesn't seem to want to run from cacti. It runs fine manually as the Cacti user and sends the proper data.

Oh well ...

Ottomatic mentioned:

Step 7: Now... In all of the blanks that say... "get code from..." Go to that website and search for your code. Once have found the weather for your city. In the address bar there is a "?id=" and then there is a few letters... That is your code. Put that in all the blanks that say "get code from..." then click create at the bottom.

So, do I leave "?id" in the field before enterri ng the code? I'm getting null values for all.

I'm getting horrible gaps! See attached image.

The problem might be on the server side though. When the gaps happen I can run the script by hand and it outputs the following:

DewPoint:1.2 HeatIndex:1.2

and thats all. Going to the URL that the perl script tries to parse I get an error message:

Code:
Site is Temporarily Unavailable

The most current observation for the site you requested is more than 4 hours old. The closest sites to the one you selected with data available are listed below:


And when I click in my city it just redisplays the same page. So I'm not sure what is going on here but somehow the script seems to be getting a value of 1.2 somewhere that it is spitting out when this happens. Perhaps it needs a little more tweaking when it comes to error handling

i am having a problem locating the correct code for a site i have in Canada. I even have the Longitude and Latitude of the site, and i cannot locate a code for them. I have the Z code from the Weatherbug page, but i don't think that will work, will it?

thanks

hbokh, how did you get the perl script to output in °C instead of F? I use weatherbug.pl EHRD (For Rotterdam Airport) but get Temp:33.8 (would be nice two but it should be much less )

Or did you make any changes to the templates? If so, can you post them here?


Use "Units=1" in the URL in the script:

Code:
my $httpaddr = "http://www.aws.com/aws_2001/asp/obsforecast.asp?Units=1&id=" . $ARGV[0];


Oh and don't forget to replace the F into C in the XML-template too.



Will that only fix the temperature? If yes, how to I change the windspeed from miles/hour to kms/hour?

Not all METAR-codes seem to work?

For example: NZSP is a valid METAR-code, but the WeatherBug script only returns 0's:
Code:
DewPoint:0.0 Humidity:0.0 Temp:0.0 Wind:0.0 Pressure:0.00 Rain:0.00 HeatIndex:0.0

Looks like you guys are in luck yet again.

I have been on cacti hiatus, but I am now back in the game. I started running this script again and got fed up with it.

The gaps are because of the aws site timing out. This causes the perl script to keep running, which explains why your processes keep going up. Run this to see:

Code:
ps aux | grep perl

you can kill them with:
Code:
killall perl


that will show you all your perl processes running trying to grab the data from that site. Cacti does a nasty job of cleaning up, and if it doesnt collect its data in a certain amount of time, it doesnt kill its child processes.

I have rewritten the script to use timeouts. The timeout is now user defined and will retry a set number of times if it is reached. I am graphing the # of tries now too to see if its something that happens at certain times during the day or if its just the certain weather code I chose.

I am not releasing this just yet, but it will be soon. I want to test it for a while first.

Any suggestions in the meantime?

BTW... no gaps in my graphs now!
