Python and Zabbix APIs to implement and modify the function of monitor host

Zabbix API can be very convenient management monitoring items, powerful, very suitable for two times development. The main function of this article is that Django Asset Management update can sync to Zabbix monitoring platform, unified platform function, ensure data consistency.

Zabbix API

The Host.create,host.delete,host.update,host.get and Hostinterface.update methods are mainly used in the Zabbix API. The following has been create for example to do the simple use instructions.

The code is as follows	Copy Code
{ "Jsonrpc": "2.0", "Method": "Host.create", "Params": { "Host": "Linux Server", "Interfaces": [ { ' Type ': 1, "Main": 1, "Useip": 1, "IP": "192.168.3.1", "DNS": "", "Port": "10050" } ], "Groups": [ { "GroupID": "50" } ], "Templates": [ { "TemplateID": "20045" } ], "Inventory": { "Macaddress_a": "01234", "Macaddress_b": "56768" } }, "Auth": "038e1d7b1735c6a5436ee9eae095879e", "id": 1 }

Parameters

JSONRPC: Default 2.0, no modification

Method: Specify the methods of the API

Params: the requested parameter. Where host is the hostname, the name that is displayed on the Zabbix page. Interfaces is the real information of the host, including type, IP address and port, etc. Groups the group to join when the host is added, this must be specified. Templates represents the Zabbix template ID to use when adding a host, optionally, the recommended addition of a common template ID number. Inventory Asset Management, this I did not add.

Auth: The SessionID number after landing

ID: The ID number of the operation, and this particular effect is not studied in depth. What number is the request ID, and what number is displayed when returned.

After the success of the creation, the following contents are returned:

The code is as follows	Copy Code
{ "Jsonrpc": "2.0", "Result": { "Hostids": [ "107819" ] }, "id": 1 }

Python calls

After understanding the Zabbix API, it is simpler to implement in Python, input parameters, initiate a request, and return the result.

User Login exit code is similar to the following:

code is as follows

copy code

def login (): url = settings. zabbix_url+ "/api_jsonrpc.php" data = Json.dumps ( { "Jsonrpc": "2.0", "Method": "User.login", "Params": { "User": Settings. Zabbix_username, "Password": Settings. Zabbix_password }, "id": 0 }) result = Requesturl (URL, data) return result def logout (SessionID): url = settings. zabbix_url+ "/api_jsonrpc.php" Data=json.dumps ( { "Jsonrpc": "2.0", "Method": "User.logout", "Params": [], "id": 1, "Auth": SessionID } ) Return Requesturl (URL, data)

The code to create the host is similar to the following:

code is as follows

copy code

def genhost ( Sessionid,ip,groupids):  url = settings. zabbix_url+ "/api_jsonrpc.php"  groups_list=[]  for groupid in groupids:  groups_ List.append ({"GroupID": GroupID})  params_dict={   "host": IP,   "Interfaces": [  {   "type": 1,   "main": 1,   "Useip": 1,   "IP": IP,   "DNS": "",   "Port" ":" 10050 "  }  ],  " groups ": Groups_list,  " Templates ": [  {  ] TemplateID ": 10114    ],    data=json.dumps (  {  " JSONRPC ": "2.0",   "method": "Host.create",   "params": params_dict,   "auth": SessionID,   "id ": 3  }"  return requesturl (URL, data)

When the IP update is more cumbersome to write, you need to get HostID and Hostinterfaceid separately, and then invoke the Host.update and Hostinterfa.update methods respectively.
