6 months ago Hi there,
I encountered a similar issue running Zabbix 6.4.10. The original line of code you mentioned seems to expect parameters (real_hosts and with_graphs) that no longer have direct support or behave differently in recent Zabbix API versions.
I managed to populate the 'Host Group' dropdown by adjusting the query to fetch all host groups first and then filter them based on whether they contain any hosts with graphs. Here's the adjusted approach:
Original Code:
// This original code might not work as expected due to parameter compatibility issues with newer Zabbix versions.
#$host_groups = ZabbixAPI::fetch_array('hostgroup','get', array('output'=>array('groupid','name'),'real_hosts'=>'1','with_graphs'=>'1','sortfield'=>'name') )
# or die('Unable to get hosts: '.print_r(ZabbixAPI::getLastError(),true));// First, fetch all host groups without applying 'real_hosts' and 'with_graphs' filters.
$host_groups = ZabbixAPI::fetch_array('hostgroup', 'get', array(
'output' => array('groupid', 'name'),
'sortfield' => 'name'
))
# or die('Unable to get host groups: ' . print_r(ZabbixAPI::getLastError(), true));// Now, iterate over these groups to filter them according to specific criteria. $filtered_host_groups = []; foreach ($host_groups as $group) { // Make an API call to fetch hosts by group that have graphs. Adjust this part according to your implementation. $hosts = ZabbixAPI::fetch_array('host', 'get', array( 'output' => 'extend', 'groupids' => $group['groupid'], 'with_graphs' => true // Assuming this filter can be applied here. Adjust as needed. ));
// If hosts with graphs were found in the group, then include the group in the filtered list.
if (!empty($hosts)) {
$filtered_host_groups[] = $group;
}}
// Reassign the filtered groups back to $host_groups so the rest of the code is unaffected. $host_groups = $filtered_host_groups;
This workaround fetches and filters host groups to include only those that contain hosts with graphs. Please adjust the API call parameters ('output' => 'extend', 'with_graphs' => true) as per your Zabbix setup and API version compatibility.
Hope this helps!

Running Zabbix 6.4.10 - after updating ZabbixAPI.class.php reports are working again, however only for individual hosts, when I select 'Host Group', the list is empty. Checked the logs, didn't find any error so it looks to me that the line $host_groups = ZabbixAPI::fetch_array('hostgroup','get',array('output'=>array('groupid','name'),'real_hosts'=>'1','with_graphs'=>'1','sortfield'=>'name') ) ... returns an empty array. Any idea?
