Check_MK Werk 8035: Inline-SNMP now handles errors in case of SNMP errors like "noSuchName ..."

by Lars Michelsen

ID: 8035 Title: Inline-SNMP now handles errors in case of SNMP errors like "noSuchName ..." Component: inline-snmp Level: 2 Class: Bug fix Version: 1.2.5i1 Previous versions made SNMP communication fail once a single OID could not be fetched. This has been fixed to match the behaviour of the classic SNMP code.

Check_MK Werk 8036: Suppressing unwanted error messages

by Lars Michelsen

ID: 8036 Title: Suppressing unwanted error messages Component: inline-snmp Level: 1 Class: Bug fix Version: 1.2.5i1 In some cases, the netsnmp library directly outputs error messages to stdout. This can be disabled by setting the verbose option of the netsnmp module to 0, which is set to 1 by default. Hopefully this does not suppress too many helpful error messages.

Check_MK Werk 8037: Inline-SNMP bulk walk now handles timeout errors like the classic SNMP code

by Lars Michelsen

ID: 8037 Title: Inline-SNMP bulk walk now handles timeout errors like the classic SNMP code Component: inline-snmp Level: 1 Class: Bug fix Version: 1.2.5i1 Previous versions produced error messages like "Empty response to SNMP query for ..." in case of a timeout when doing a bulk walk with inline SNMP. This was a different handling to non bulk walk queries and SNMPv1, which resulted in strange error behavious. This has now been consolidated and fixed. These timeouts are now mostly suppressed and are only visible when using the <tt>-v</tt> flag with <tt>check_mk</tt>.

by Lars Michelsen

ID: 8032 Title: Add information about previous hard state of hosts and services Component: cmc Level: 1 Class: Bug fix Version: 1.2.5i3 This is needed to provide the rule based notifications with information about the original state of an object, when an alert happens and the object has more than one check attempt.

Check_MK Werk 8033: Fix PING check on clusters without services

by Lars Michelsen

ID: 8033 Title: Fix PING check on clusters without services Component: config Level: 1 Class: Bug fix Version: 1.2.5i3 The PING check that is created on clusters that have no other services always failed with <tt>check_icmp: Failed to resolve -m</tt>. This happened only some operating systems only (e.g. RedHat 6.5). The reason is probably in different versions of the <tt>getopt</tt> function. This has been fixed.

Check_MK Werk 8031: Allow to limit number of hosts and service via config

by Lars Michelsen

ID: 8031 Title: Allow to limit number of hosts and service via config Component: config Level: 1 Class: New feature Version: 1.2.5i1 There are now two new global settings for <tt>main.mk</tt> that allow limiting the number of monitored hosts and/or services. This option only works when using the Check_MK Micro Core. Example: F+:main.mk cmc_host_limit = 100 cmc_service_limit = 3000 F-: If you now try to activate a configuration with more than 100 hosts or more then 3000 services you will run into an error and the old configuration is being kept. It is also possible to just set a limit on hosts <i>or</i> services. Setting the according variable to <tt>None</tt> deactivates the limit. This is the default. This setting can <b>not</b> be changed via WATO. It can be useful in situations where you give access to a user or customer via WATO but want to restrict the amount of objects that he/she can monitor.

Check_MK Werk 8028: Fix column last_hard_state: show same value as soft state

by Lars Michelsen

ID: 8028 Title: Fix column last_hard_state: show same value as soft state Component: cmc Level: 1 Class: Bug fix Version: 1.2.5i1 The livestatus implementation of the Micro Core did output the current state instead of the last hard state in the column last_hard_state. This has been fixed.

Check_MK Werk 8029: New external command for creating log entries

by Lars Michelsen

ID: 8029 Title: New external command for creating log entries Component: cmc Level: 1 Class: New feature Version: 1.2.5i1 The core has now the new external command LOG. This creates entries in the monitoring history. It is currently being used by the overhauled Check_MK notification system in order to log the notifications that are actually be sent out after condideration of notification rules.

Check_MK Werk 8030: Set default host check interval for non-Smart-PING hosts to 60 seconds

by Lars Michelsen

ID: 8030 Title: Set default host check interval for non-Smart-PING hosts to 60 seconds Component: config Level: 1 Class: Bug fix Version: 1.2.5i1 The host check interval for hosts when using the Micro Core has been 6 seconds. This is a good setting when using Smart-PING (which is the default). When you switch to an alternative command like <tt>check_tcp</tt>, then 6 seconds is too fast in most situations. So we changed the default interval for all non-Smart-PING hosts to 60 seconds.

Check_MK Werk 8027: CMC now allows spaces in the names of performance variables

by Lars Michelsen

ID: 8027 Title: CMC now allows spaces in the names of performance variables Component: cmc Level: 1 Class: Bug fix Version: 1.2.5i1 This makes the Micro Core compatible to the different variants that Nagios allows for performance data variables. Now it is allowed to specify <tt>"foo bar test"=18</tt> or <tt>'foo bar test'=18</tt> as performance data. This means that the name of the variable may be quoted with either single or double quotes.
