Check_MK Werk 2339: Discovery service: Fixed handling of agent / snmp communication errors

ID: 2339 Title: Discovery service: Fixed handling of agent / snmp communication errors Component: Core & Setup Level: 1 Class: Bug Fix Version: 1.2.7i2 When a host could not be contacted via agent or did not receive an SNMP response, this resulted in a situation where the check was shown as UNKNOWN and broken check with the hint to send a bug report the us. This handling has been changed to reporting a WARNING state together with the related error message as output. The "crashed check" link is not displayed for this case anymore.
