From cdbbd79155a7752843f2b420c3036ce6c390a3b6 Mon Sep 17 00:00:00 2001 From: Thomas Weber Date: Wed, 21 Jul 2021 07:42:39 +0200 Subject: stats: add a interval parameter to cli and api stream mode podman stats polled by default in a 1 sec period. This can put quite some load on a machine if you run many containers. The default value is now 5 seconds. You can change this interval with a new, optional, --interval, -i cli flag. The api request got also a interval query parameter for the same purpose. Additionally a unused const was removed. Api and cli will fail the request if a 0 or negative value is passed in.
