# 5 Page parameters

#### Overview

Most Zabbix web interface pages support various HTTP GET parameters that
control what will be displayed. They may be passed by specifying
parameter=value pairs after the URL, separated from the URL by a
question mark (?) and from each other by ampersands (&).

#### Status of triggers

Accessed as *Monitoring → Triggers*, page name `tr_status.php`.

::: noteimportant
To set the filter, parameter `filter_set=1` must
be passed. Fields that are not specified will be reset to default
values.

**Inventory filter**

Since Zabbix 2.4.0, triggers can also be filtered by inventory. Here the
syntax is a bit more complicated. Inventory fields and their values are
added as zero-based index entries, for example:

    inventory[0][field]=type_full
    inventory[0][value]=Virtual machine
    inventory[1][field]=os_full
    inventory[1][value]=Linux

These must be URL-encoded, though. The passed values would look like:

    inventory%5B0%5D%5Bfield%5D=type_full
    inventory%5B0%5D%5Bvalue%5D=Virtual machine
    inventory%5B1%5D%5Bfield%5D=os_full
    inventory%5B1%5D%5Bvalue%5D=Linux

Inventory field codes can be found in the [Zabbix API host object
documentation](/manual/api/reference/host/object#host_inventory).

#### Trigger events

Access to events of a specific trigger, which may be useful for
notifications is to use a URL like:

    http://<server_ip_or_name>/zabbix/events.php?triggerid={TRIGGER.ID}&filter_set=1
