## Create a URL to silence form with defaults filled in
When linking to silence form, you can provide default matching labels and comment via `matchers` and `comment` query parameters. `matchers` expects one more matching labels of type `[label][operator][value]` joined by a comma. `operator` can be one of `=` (equals, not regex), `!=` (not equals, not regex), `=~` (equals, regex), `!~` (not equals, not regex).
When linking to a silence form, provide the default matching labels and comment via `matchers` and `comment` query parameters. The `matchers` parameter requires one more matching labels of the type `[label][operator][value]` joined by a comma while the `operator` parameter can be one of the following: `=` (equals, not regex), `!=` (not equals, not regex), `=~` (equals, regex), `!~` (not equals, regex).
For example, to link to silence form with matching labels `severity=critical` & `cluster!~europe-.*` and comment `Silence critical EU alerts`, create a URL `https://mygrafana/aleting/silence/new?matchers=severity%3Dcritical%2Ccluster!~europe-*&comment=Silence%20critical%20EU%20alert`.
