In information systems word “tag” is a well-known and widely used term that helps to describe an item and allows it to be easily found again by browsing or searching.
In Zabbix, tags provide a useful way to group related events together and quickly tell users what a certain event is about. Tags are similar to, but more specific than, groups. The use of tags is completely optional, but may be extremely useful, for example, in event correlation, when defining tag-based user permissions, configuring maintenance and email notifications, or when filtering your content by specific tags.
If you have not used event tagging before and wonder what benefits it brings, or just want to know which improvements to event tags are awaiting you in Zabbix 4.2, you’re in the right place.
