Title: logwatch: unacknowledged messages exceeding the max size are now dropped, even if they were already stored due to a previous bug
Component: Checks & Agents
Level: 1
Class: Bug Fix
Version: 1.2.7i3
A previous modification to the logwatch check caused the internal message buffer
(var/check_mk/logwatch) to become bloated, causing high cpu load and memory usage.
This change now auto-corrects those files for those affected.

Title: Added native support for monitoring via IPv6
Component: Core & Setup
Level: 2
Class: New Feature
Version: 1.2.7i3
Check_MK is now providing native support for monitoring IPv6 and even dual-stack hosts.
This has been implemented in a clean and straight forward way. For each host you can
choose which address family shal be used for communication with this host. By default
Check_MK is still using only IPv4, but now you can change it to IPv6 for monitoring
IPv6 only hosts. In WATO this is done by configuring the host attribute <i>IP Address Family</i>.
You can even configure one host to be monitored via IPv4 and IPv6 at the same time. In
this situation you need to decide which of the both address families is the primary one.
The primary address family is the one which is used for regular monitoring tasks
(communication with the agent or SNMP). The secondary address family is only being
pinged by default. For the secondary address family a dedicated PING service named
(PING v4 or PING v6) is added to the dual-stack hosts.
By default the primary address family is IPv4 for all dual-stack hosts. In WATO this
can be changed by configuring the rule set <i>Primary IP address family of dual-stack hosts</i>.
In some cases you want to perform active checks to check the avilability of a service,
e.g. HTTP, using both IPv4 and IPv6. For this case you can add two active checks to
the dual-stack host, one having IPv6 enabled and one without having it enabled for
using IPv4. But each active check needs to support IPv6 on its own. For the moment
the only check working vith IPv6 is <tt>check_http</tt>.
This is the default and recommended way for monitoring dual-stack hosts. You use one
address family for monitoring the whole system and the other one is just being pinged.
Note: If you use the Check_MK Enterprise Edition togehter with the Micro Core,
the Smart PING mechanism is not used for IPv6 hosts at the moment. This mechanism has
a slightly slower performance, but if you don't have too many IPv6 hosts, this should
be OK for the beginning.
The basic implementation for IPv6 monitoring has been done. But there are several
components in the Check_MK environment left which need to be extended to be fully
compatible with IPv6. Some of them are:
LI: Parent scanning (check_mk --scan-parents)
LI: WATO - Host-Diagnose
LI: WATO - Most active checks
LI: Event Console
LI: Notification Forwarding
LI: Livestatus Proxy
LI: Several active checks
LI: Most special agents
LI: The Check_MK Appliance

Title: cisco_asa_failover: Failover state is not treated as warning state anymore
Component: Checks & Agents
Level: 1
Class: Bug Fix
Version: 1.2.7i3
The Cisco ASA cluster is operating as expected and in practice, it does not really
matter which of the cluster members is the primary one. So the failover state, where
the secondary device is the active one, is not treated as warning anymore.

The problem occured when there were very many performance counters on the system.

Title: SNMP-Traps: Fixed translation of OIDs which are parts of trap values
Component: Event Console
Level: 1
Class: Bug Fix
Version: 1.2.7i3
Some traps send SNMP OIDs as values of traps which were not translated correctly
in the past. For example default SNMPv2 traps had a non-translated numeric OID
in the "Application" field of the events. This has now been changed to be
translated too.
Please note: If you already have created rules which refer to the numeric OIDs
while having trap translation enabled, you will need to update the rules.

Title: etherbox2_temp: new check for the etherbox 2 (from firmware version 1.21 on) / MessPC
Component: Checks & Agents
Level: 1
Class: New Feature
Version: 1.2.7i3
To run this check you have to configure the WATO rule <i>Hosts without system description OID</i>.
