API how to create trigger

[chemistmail]

Hello all.
Sorry for my bad english.
I want to create trigger with API.
But how?
I have installed zabcon.
this code create item

#!/usr/bin/ruby      
require './zabbixapi.rb' 

zbx=ZbxAPI.new(url)
zbx.login(login,password)
name = "test"
hostid = 10161
item_p = { 
   'description'=>name, 
   'key_'=>"my.key",
   'hostid'=>hostid,
   'type'=>'0'
   'data_type'=>0,                                                                                                         
   'value_type'=>0,                                                                                                        
   'units'=>"%"  }  

uid = zabbix.item.create(item_p) 

But how to create trigger.

)) thanks

    expression="{#{hostname}:vfs.fs.size[#{disk},pfree].last(0)}<10"
    description="API Free diskspace on {HOSTNAME} volume #{disk}"
    item_t={
          'hostid' => hostid,
          'expression'=>expression,
          'description'=>description,
          'priority'=>HIGH,
          'status'=>ENABLE,
    }
#    p item_t
    begin
     uid = zabbix.trigger.create(item_t)
      p "cant create trigger on #{hostname} disk #{disk}" if uid.nil?
    end

create trigger

in zabbixapi.rb comment 2 string

    if !resp["error"].nil?
##      raise ZbxAPI_GeneralError, resp["error"] # comment it!
    end
     
                return resp
##             rescue Redirect                  # comment it!
                redirects+=1
                     retry if redirects<=5
                     raise ZbxAPI_GeneralError, "Too many redirects"
             end 

and now
here script for create check drive on servers

#!/usr/bin/ruby
# 
require './zabbixapi.rb'
 
zbx=ZbxAPI.new('http://zabbix.server.com')
zbx.login('login','password')

# trigger
HIGH=4
AVERAGE=3
WARNING=2
INFORMATION=1

ENABLE=0
DISABLE=1

# return hostid
def hostid_from_hostname(hostname,zabbix)
 for host in zabbix.host.get({"extendoutput"=>true,'pattern'=>"#{hostname}"})
     return host['hostid']
 end
end

def add_disk_check(hostname,zabbix)
 # get drive from servers
 ssh=`ssh -o "StrictHostKeyChecking no" -q #{hostname} 'df -l -P -h | tail -n +2' `

 hostid=hostid_from_hostname(hostname,zabbix)
 for l in ssh
    disk=l.split[5].gsub("/","\/")
    name="API Free diskspace on #{disk}"

    item_p = {
     'description'=>name,
     'key_'=>"vfs.fs.size[#{disk},pfree]",
     'hostid'=>hostid,
     'type'=>'0',
     'data_type'=>0,
     'value_type'=>0,
     'units'=>"%"
    }

    begin
     uid = zabbix.item.create(item_p)
     p "cant create item on #{hostname} disk #{disk}" if uid.nil?
    end

    expression="{#{hostname}:vfs.fs.size[#{disk},pfree].last(0)}<10"
    description="API Free diskspace on {HOSTNAME} volume #{disk}"

    item_t={
         'hostid' => hostid,
         'expression'=>expression,
         'description'=>description,
         'priority'=>HIGH,
         'status'=>ENABLE,
    }

    begin
     uid = zabbix.trigger.create(item_t)
     p "cant create trigger on #{hostname} disk #{disk}" if uid.nil?
    end

 end
end

# now create items and triggers on all servers
for host in zbx.host.get({"extendoutput"=>true})
 id=host['hostid']
 hostname=host['host']
 puts "#{id} -- #{hostname}"
 add_disk_check(hostname,zbx)
end

# the end 

its work.

I have scripts for create items and triggers for loadaverage and other.
Now i write script for create items, triggers and graphs for checking openvz user_beancounters.
I can write it in wiki, but prefer russian langvich. )

English is not my nature langvich.
По русски было бы проще.
