Dash0 is designed to be your central observability system, containing data from various systems and spanning multiple teams. To quickly access relevant information, you need context and flexible filtering.

Each view in Dash0 provides quick access to Filtering.

The filtering capabilities are slightly different depending on the context. Filters can be accessed using the Filter icon in the top navigation of Dash0 (quick access using shift+F as a shortcut and accessing the filter from the command menu cmd/ctrl+k is also possible).

When adding a filter, the key to be filtered on is selected first. Dash0 will offer all available and relevant keys, indicating how many records grouped by status are found.
After selecting the key, an operator for the filter needs to be specified. The operator can be selected by mouse, defined as text (is / equals), or by using the indicated shortcut ("=").
After specifying the operator, the applicable values and an indication of the matching resources are shown. Depending on the operation, you can select one or multiple options.
After specifying the value(s), the filter is automatically added to the filter bar. You can modify the filter by clicking on the filter component (key, operator, or value) you want to modify, or you can remove the filter by clicking on "x."
To add more filters, you can use the "+" button in the filter bar or add filters as described above.

Pinning filters

You can pin any active filter so it persists as you navigate between pages. Pinned filters stay active when you move from the Trace Explorer to the Log Explorer, to Services, to Resources, and so on, until you explicitly remove or unpin them.

How to pin a filter

Hover over or click a filter to expand it
Click the pin icon
The filter is now pinned and visually distinguished from unpinned filters

How to unpin a filter

Hover over or click the pinned filter to expand it
Click the pin icon again to unpin it

Notes

Multiple filters can be pinned at the same time
Pinned filters work across all pages that support the filter bar: Trace Explorer, Log Explorer, Services, Resources, Websites, and Failed Checks

Filter conflicts

A conflict occurs when two or more active filters check the same attribute key with different values. For example, service.name = frontend and service.name = backend active at the same time. A single attribute cannot hold two different values simultaneously, so this typically returns no results.

When the filter bar detects a conflict, it shows a warning and highlights the conflicting filters so you can identify them.

Common causes:

A pinned filter carried over from one feature conflicting with a filter already active in another
Adding a filter that contradicts an existing pinned filter

Resolving a conflict

When a conflict is detected, click Resolve. The suggested resolution merges the conflicting values into a single filter that matches any of them.

Example:

Conflict: service.name = frontend AND service.name = backend
Resolution: service.name is one of frontend, backend

Click Accept to apply it. The conflicting filters are replaced by the merged one.

Copying a filter

You can copy a single filter without copying your entire filter list.

Hover over or click a filter to expand it
Click the copy icon
The filter is in your clipboard and can be pasted into any filter bar input

Troubleshooting

Filters not returning expected results after navigating from another page

A pinned filter from the previous page may be conflicting with a filter on the current page. Check the filter bar for a conflict warning and use Resolve to merge them.

Pinned filter not appearing after navigation

Pinned filters only carry to pages that have a filter bar: Trace Explorer, Log Explorer, Services, Resources, Websites, and Failed Checks. Dashboards, Synthetics, Check Rules, and Agent0 do not have a filter bar.

Copy not working as expected

The filter must be expanded before the copy icon appears. Click or hover on the filter first, then click the clipboard icon.
