Terms
We recommend only utilising the following aggregations in your Kibana instance at the present time. These will be more than sufficient for your analytical requirements currently If you wish to try using others, or think you have a requirement to, please contact us so we can assist. We will update this list as and when other aggregations become suitable for use.
Date Histogram
Allows you to select a field to aggregate the data by and then specify an interval such as daily, weekly, monthly.
Date Range
Allows you to enter a specific date range to filter by such as start of year to present, last week to this week. See our "Dates in Kibana" article to help you set date ranges that meet your needs.
Filters
Allows you to split the visualisation by specific filters using keywords or dates. You can also split it by multiple filters for better results.
Terms
Terms is were you can look for specific types of record based on their name and the data set you are using., for example, statusName. If you are trying to filter by terms and you cannot see a term you think should be there, please contact us.
