How long does zabbix keep a history of notifications/triggers?

Just as the title asks, how long does zabbix keep a history of triggers/notifications?

Going to Monitoring --> Triggers and looking through the filter, the drop down for 'Events' has an option for 'Show all (7 days)'. Does this mean zabbix can only show triggers from the last 7 days?

If the history limit to search through recent triggers is 7 days, can this history be modified to a greater number, say 365 days?

in monitoring -> triggers limit by default is 7 days and you can customise that in administration -> general -> gui.

you can see more events in monitoring -> events, and that is limited by what's in the database, and can be controlled in administration -> general -> housekeeper

Richlv, as always, thank you for the extremely helpful and useful reply. The zabbix community as a whole is a great resource and it's nice to know there are folks here who are experts with the zabbix stack and willing to share their knowledge with others.

Alerts history duration

in monitoring -> triggers limit by default is 7 days and you can customise that in administration -> general -> gui.

you can see more events in monitoring -> events, and that is limited by what's in the database, and can be controlled in administration -> general -> housekeeper

I would like to analize history of alerts events. Which of setting allows me to increase period of alerts history up to 30 days?

alerts are kept as long as the events are - notice how the housekeeper section is even called "Events and alerts"
