Zabbix 1.8 API and Perl

[stu42j]

Does anyone else access the Zabbix API from Perl. Do most people use one of the JSON-RPC libraries from CPAN?

I've been working on a simple API wrapper module in Perl. Would there be any interest in sharing or development?

[nelsonab]

I can help collaborate with you if you'd like. Also if you would like I can host your code along side the Ruby Zabbix API libraries.

[stu42j]

What I have is just a simple wrapper, it doesn't do any verification of API methods or attributes. Since it meets my needs, I probably won't be developing it any further. I'm happy to share it as an example, though.

hi!

thanks for posting this. in the last hours i just figured out how to handle this json stuff myself, but a ready module is very welcome ;-)

thanks,

Stuart, would it be possible to post a simple code how to use the library?
It would be very much appreciated!

Thanks,
Marcel

Sure, here is a sample usage:

use Net::Zabbix;

my $url = 'http://192.168.0.1';
my $z = Net::Zabbix->new($url, $user, $password);
my $trigger = $z->get('trigger', { triggerids => [$trigger_id] });

I'm not using Zabbix anymore so I don't know if the module works with 1.8.

Thanks Stu!

I can confirm that the conde works with 1.8.3 - actually I am alerady using it extensively for some auto-discovery of items on low level and additn ght items into Zabbix.

What do you use instead Zabbix?

Zabbix 1.8 API and Perl

I'm trying the given Perl api and getting very empty answers. From viewing the request and answer with tcpdump it looks all valid, I just get empty answers.

Relevant perl code:

my $zabbixsession = Net::Zabbix->new($server,$user,$pass);
my $sslgroupobject = $zabbixsession->get('host', { output => 'extend', filter => { name => [ $hostname] }});
print Dumper($sslgroupobject);

The dumper output is always:

$VAR1 = {
          'jsonrpc' => '2.0',
          'id' => 2,
          'result' => []
        };

looking at the request/reply traffic with tcpdump shows reasonable values:

User-Agent: Net::Zabbix
Content-Type: application/json-rpc
Content-Length: 120
{"auth":"197822c2af350d08c4fec02a41c12302","params":{"output":"extend"},"jsonrpc":"2.0","id":2,"method":"hostgroup.get"}
HTTP/1.1 200 OK
Date: Fri, 05 Nov 2010 14:50:07 GMT
Server: Apache/2.2.3 (Scientific Linux)
X-Powered-By: PHP/5.1.6
Set-Cookie: zbx_sessionid=197822c2af350d08c4fec02a41c12302
Content-Length: 36
Connection: close
Content-Type: text/html; charset=UTF-8
{"jsonrpc":"2.0","result":[],"id":2}

The earlier user.authenticate call goes through fine.

I have tried several types of filters / non-filters or other parameters.

Update: it helps when the api-user has access to the group(s) you want data from.

[marcel]

try "pattern" instead of "filter"

Now to get the templates linked to a host

Succes with that bit (just make sure the API user has actual access to the object).

Now for my next issue: I get a list of hosts. Now I want to know the linked templates per host.

I can get all templates (that I have access to), but I can't filter a selection of templates per host yet.

Update:
Bug in the documentation: using select_templates with host.get (and NOT selectParentTemplates) I can fetch the templates for each host.

hmm. is that some older version of the api, maybe ? latest version should work as documented

Still running 1.8.2. Which may be the cause of other problems.

[richlv]

oh. i would suggest to wait for upcoming 1.8.11 and upgrading to that one then
