cannot connect to IPMI host: [125] Operation canceled
possibly authentication method issue
Discover: value must be a JSON object
Could mean you need to escape slashes

{"{#VAR1}":"value21","#{VAR2":"value22"}
]}

Latest 20 issues
DEFAULT_LATEST_ISSUES_CNT in/usr/share/zabbix/include/defines.inc.php
Zabbix unreachable poller processes more than 75% busy
Increase StartPollersUnreachable
More than 100 items having missing data for more than 10 minutes
Could be high load. Also check Administration->Queue
Zabbix escalator processes more than 75% busy
probably high system load overall
Check agent
zabbix_get -s my.host.com -k agent.version
ZBX_NOTSUPPORTED
Could be anything, enable logging on agent. It could be version mismatch. Check
zabbix_get -s yourhost -k agent.version
If that works, you're calling for an undefined or unsupported key.
Incorrect trigger expression. Host "xx" does not exist or you have no access to this host.
Means there's no related item.
zabbix_get returns nothing
best look at log on agent side
run playbook on single host
ansible_playbook -l somehost somplay.yml
Zabbix server is not running: the information displayed may not be current
Might be selinux: http://sysads.co.uk/2013/11/zabbix-server-running-alert/
vmware.hv.cpu.usage[{$URL},{HOST.HOST}]" became not supported: Couldn't resolve host name
Set macro {$URL} to https://your.ip/sdk/ (shouldn't discovery figure that out from {$HOST} ?
unsupported item key
This might mean it's expecting a value from the script you're calling.
echo 1
ansible or API not showing host groups
Permissions!! See Administration->User Groups
