Subject: [lustre-devel] [PATCH 26/26] lnet: add "stats reset" to lnetctl
Date: Mon,  2 Aug 2021 15:50:51 -0400	[thread overview]
Message-ID: <1627933851-7603-32-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1627933851-7603-1-git-send-email-jsimmons@infradead.org>

From: Cyril Bordage <cbordage@whamcloud.com>

This new command resets stats shown by "lnetctl stats show". It could
be useful when debugging connectivity issues, by making easier the
process to detect the changes in stats from the clean state rather
than on top of historical values.

WC-bug-id: https://jira.whamcloud.com/browse/LU-13299
