From: Marc Fournier Date: Tue, 28 Oct 2014 14:46:20 +0000 (+0100) Subject: varnish: adapt to metrics renames & deprecations in varnish4 X-Git-Tag: collectd-5.5.0~138^2~6 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a9a8e4bcd0e688e054ae816813475c8784cc4012;p=collectd.git varnish: adapt to metrics renames & deprecations in varnish4 Summary of changes: - connections: "accepted" & "dropped" are now found in the session section - dirdns: doesn't exist in varnish 4 anymore - objects: "n_obj*" were removed from varnish 4 - ban: "obj", "req" & "completed" bans were added. As a lot of new "tested" metrics are available, so we only collectd the overall total now - session: metrics from "connections" and "threads" categories were moved here - struct: "n_sess*" were removed - totals: new, more detailed *bytes metrics were made available - threads: new metrics were made available. "queued" was moved the session section. --- diff --git a/src/varnish.c b/src/varnish.c index f349bf5a..e3b6cec1 100644 --- a/src/varnish.c +++ b/src/varnish.c @@ -73,7 +73,7 @@ struct user_config_s { #endif _Bool collect_struct;
