Create "Filters" with API

[exajul]

I am currently testing out the API and unfortunately I cannot find an option to do the following task with the API.

Under Monitoring -> Hosts there's the possibility to filter for specific hosts. I can also save the Filter with the "Save as" button (I can also select if I want to show the number of records).

Afterwards I can access the filter again.

So is there also a way to do this via API?

Hello,
If got the issue correctly, you want to get total objects from the specific filter configuration. It looks that you need to use "host.get" method with output option "output":["hostid"] and than count all ID`s.
Check API documentation https://www.zabbix.com/documentation...rence/host/get and https://www.zabbix.com/documentation/7.0/en/manual/api

As examples it could be done with a bash script that POSTs to Zabbix server, transforms result to json, counts the lines and subtracts non relevant json lines:

expr $(curl --request POST \
              --url 'http://<ZABBIX SERVER HOST>/api_jsonrpc.php' \
              --header 'Authorization: Bearer <AUTORIZATION TOKEN>' \
              --header 'Content-Type: application/json-rpc' \
              --data '{"jsonrpc":"2.0","method":"host.get","params":{"output":["hostid"],"filter":{"host":["Zabbix server"]}},"id":1}' | \
              jq | wc -l) - 8

or second example with Python "zabbix_utils" library: https://github.com/zabbix/python-zabbix-utils

from zabbix_utils import ZabbixAPI
api = ZabbixAPI(url="http://<ZABBIX SERVER URL>/")
api.login(user="Admin", password="zabbix")
filter = api.host.get(
    output = "hostid",
    filter = {"host":["Zabbix server"]}
)
print(len(filter))
api.logout()

Would be nice if that was the workaround. But unfortunately I don't only want the host count. I want to create the filter.
I am searching more like a function that does something like: filter.update or filter.create :/

I think OP wants to create filters over API. But there doesnt seem to be such method... I cannot even pinpoint, where those are saved..

Yes, it looks that there not direct filter method. So for getting required hosts you need use "get" method as: host.get, hostgroup.get. In fact they quite flexible and provide filtering possibilities. As example for host.get you can get list of hosts by name, by tag or by inventory. But how you organize the request it's all about you. It could be automatically generated from script or predefined files saved in json format as in example from the documentation:

https://www.zabbix.com/documentation/7.0/en/manual/api

#cyber, What you mean about saving? Do you mean requests output? You can save it in a file, or variable and proceed it in next operations.

No I meant where those filters are saved, what you can create in UI.. and save... somewhere.. Those, what are in first post on a picture..
