From 068cc51d42f771d2a453d628c10e199e7d104edd Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 26 Apr 2022 11:49:33 +0200 Subject: qmp: add filtering of statistics by provider Allow retrieving the statistics from a specific provider only. This can be used in the future by HMP commands such as "info sync-profile" or "info profile". The next patch also adds filter-by-provider capabilities to the HMP equivalent of query-stats, "info stats". Example: { "execute": "query-stats", "arguments": { "target": "vm", "providers": [ { "provider": "kvm" } ] } } The QAPI is a bit more verbose than just a list of StatsProvider, so that it can be subsequently extended with filtering of statistics by name. If a provider is specified more than once in the filter, each request will be included separately in the output. Extracted from a patch by Mark Kanda.
