Subject: Add param to configure HAProxy default maxconn (per frontend)
X-Git-Tag: opnfv-6.0.0~847
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=f621024ea33509e77eca87acf47e84691351b84d;p=apex-puppet-tripleo.git

Add param to configure HAProxy default maxconn (per frontend)

The default per frontend maxconn is set to 2000, which can easily
be reached with modern hardware with multiple logic cores; this
change adds a parameter to configure the default maxconn value,
default it to 4096 and also increases the global maxconn to 20480
to preserve the 1:5 ratio.
