1) Do you get any errors while running weathermap program? Try running
it with debugging. It should produce html file and png file (which is
loaded by html). Check that both files exists and access to them is
allowed.
2) You didn't catch the idea of integration of weathermap and zenoss.
Weathermap can only read snmp|rrd data. You could try to point it to rrd
files produced by zenoss, but if you don't want to write file names
manually(which could be very boring) you should use another syntax in
you weathermap config file (the one called map.src with special syntax
described in how-to) and then convert it to native weathermap format.

Dear Sir,

That was kind, thanks for the reply

I tried the same steps.But I could not get the map work.

I am also confused about this line,

./convert_map.pl map.src >map.conf

I created the map using php weathermap web editor.

then I saved the file as simple.conf. (I don't know about the src file),

Then I ran

./convert_map.pl simple.conf > simple.conf

No errors here

then I created the html file

php ./weathermap --config simple.conf --htmloutput /var/www/html/simple.html

I access the link by

http://systemIP/simple.html

page is blank

I must be doing something wrong here.

Sorry for so many questions, I am a Storage Engineer, trying to learn ZenOSS.

Thanks again ,

Athreya

Dear Sir,

Thank for the reply.

My undestanding on the integration is this.

1. We create the map using the Syntaxes and it is saved as map.src

2. Then we use the convert_map.pl and create a conf file map.conf

3. Then we process map.conf with weathermap script, which will create an html file and png file

Right.

 

 

4. We access the html file using the web server. This file will have the rrd links for the devices , So the map is having a ZenOSS backend.

No, the file does not have links to rrd. When you run convert_map.pl it
reads data from zenoss (via xml-rpc call) and puts this into map.conf.
But this data are only valid for the current moment of time. It just
creates static targets in terms of weathermap.
And weathermap draws links, devises an so on according on this data.
After that you should repeat this process each 5 minutes via cron job,
i.e. you should add convert_map.pl and weathermap calls to cron.

 

 

Am I right ?

What I did

1. Created the map using web editor of the Weathermap.

2. Saved it as map.src

Web editors knows nothing about special syntax needed by convert_map.pl.
You could use it only as starting point and then edit file manually.

 

 

3. Tried to convert it with convert_map.pl

I am getting the error as ,

Global Symbol "node" requires explicit package name at ./convert_map.pl line 11

This error means that there is smth wrong in convert_map.pl. May be this
file was broken during download?
Could you post top 12 lines of this file?

 

 

I saw it is creating map.conf which zero bytes.

As soon as convert_map.pl produced errors output file is empty.

 

 

Am I anyway near ?

Regards,

Athreya

Hi Sir,

Thanks again for the reply, I really don't have words to appreciate such a detailed explanation.

Please find the 12 lines below ,

1 #!/usr/bin/perl
2 use JSON::XS;
3 use strict;
4 my server="192.168.131.89";
5 my port="8080";
6 my user="admin";
7 my password="1q2w3e4r";
8 my %devices;
9 my wget="/usr/bin/wget";
10 my wget_type=1 # 1 - older wget, 2 - later version

There is missing ; at previous line. You deleted ; symbol. It should be:

my $wget_type=1;

 

 

11 my node;
12 my url;


Also my wget version is ,

Also, my wget version

I don't know which wget version you should choose. Try both and see
which works for you.

Please, send me you source map file, result map file and what
convert_map.pl prints to screen, if it does.
Which zenoss version you are using?
These lines

['zenevents_5_noack noack', 0, 0], ['zenevents_4_noack noack', 0, 0], ['zenevents_3_noack noack', 0, 0],

should no be there. Its seems something is wrong.

Ah, may be I know what the problem is. Maybe it is because of %2F in
your interface name. Can you check it on anotherdevice with different
interface names?

Anyone else having a problem without put like this? When using ./weathermap to generate, there are complaints about the highlighted areas. The <%rrd{block}%> also doesn't seem to get replaced properly.

Any help is greatly appreciated! :-)

Ok, I will check it later.
Did you find a solution for %2F problem or your just checked it on
different device?

You're correct, it was the %2F. I'm still getting the "[['zenevents_5_noack noack', 0, 0], ['zenevents_4_noack noack', 0, 0], ['zenevents_3_noack noack', 0, 0], ['zenevents_2_noack noack', 0, 0], ['zenevents_1_noack noack', 0, 0]]" line as a result for <%status%>.

ZenOSS version is 2.4.2. Looks like severity info.
