+Cumulative number of refs included in the Git fetch operation.
+
+The `<metric>` field can have one of the values described here below,
+while the `<source>` represents the replication source endpoint name.
+
+- `started`: (counter) number of refs for which fetch operation have started.
+
+- `completed`: (counter) number of refs for which fetch operation have completed.
+
+- `failed`: (counter) number of refs for which fetch operation have failed.
+
+> Bear in mind that the fetch with special `..all..` ref spec will be counted
+> as 1 even if the fetch cause multiple refs to be fetched.
