ID: 4547 Title: check_mk_agent.linux: Fixed agent section which spammed in utmp of RHEL/CentOS Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i1 The section postfix_mailq_status was writing into utmp everytime the agent run. With the new version we are able to avoid this behaviour and still get informations about multiple instances of postfix. This fix needs an updated agent AND an updated checkplugin but a rediscovery is not neccessary.
