Subject: Report state to the GTM no more frequently than defined by
X-Git-Tag: XL9_5_R1BETA2~46
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=031c0c5424bd18bdc2e4b4014396f44acfb17a65;p=postgres-xl.git

Report state to the GTM no more frequently than defined by
CLUSTER_MONITOR_NAPTIME

Otherwise we have danger of flooding the GTM with messages in an infinite loop,
if the GTM is reporting back errors
