New in version 1.1.7i2

Incompatible Changes

• Remove config option define_timeperiods and option --timeperiods. Check_MK does not longer define timeperiod definitions. Please define them manually in Nagios.
• host_notification_period has been removed. Use host_extra_conf["notification_period"] instead. Same holds for service_notification_periods, summary_host_notification_periods and summary_service_notification_periods.
• Removed modes -H and -S for creating config data. This now does the new option -N. Please set generate_hostconf = False if you want only services to be defined.

Core, Setup, etc.

• New config option usewalk_hosts, triggers --usewalk during normal checking for selected hosts.
• new option --scan-parents for automatically finding and configuring parent hosts (see online docu for details)
• inventory check: put detailed list of unchecked items into long plugin output (to be seen in status details)
• New configuration variable check_parameters, that allows to override default parameters set by inventory, without defining manual checks!

• Fixed bug in MRPE: check failed on empty performance data (e.g. from check_snmp: there is emptyness after the pipe symbol sometimes)
• MK Livestatus is now multithreaded an can handle up to 10 parallel connections (might be configurable in a future version).
• mk_logwatch -d now processes the complete logfile if logwatch.state is missing or not including the file (this is easier for testing)
• Added missing float columns to Livestatus.
• Livestatus: new header StatsGroupBy:
• First version with "Check_MK Livestatus Module"! setup.sh will compile, install and activate Livestatus per default now. If you do not want this, please disable it by entering <tt>no</tt>, when asked by setup.
• New Option --paths shows all installation, config and data paths of Check_mk and Nagios
• New configuration variable define_hostgroups and define service_groups allow you to automatically create host- and service groups - even with aliases.
• Multiadmin has new filter for 'active checks enabled'.
• Multiadmin filter for check_command is now a drop down list.
• Dummy commands output error message when passive services are actively checked (by accident)
• New configuration option service_descriptions allows to define customized service descriptions for each check type
• New configuration options extra_host_conf, extra_summary_host_conf and extra_service_conf allow to define arbitrary Nagios options in host and service defitions (notes, icon_image, custom variables, etc)
• Fix bug: honor only_hosts also at option -C

New in version 1.0.39

Changes

• New configuration variable only_hosts allows you to limit check_mk to a subset of your hosts (for testing)
• New configuration parameter mem_extended_perfdata sends more performance data on Linux (see check manual for details)
• many improvements of Multiadmin web pages: optionally filter out services which are (not) currently in downtime (host or service itself), optionally (not) filter out summary hosts, show host status (down hosts), new action for removing all scheduled downtimes of a service. Search results will be refreshed every 90 seconds. Choose between two different sorting orders. Multadmin now also supports user authentication
• New configuration option define_timeperiods, which allows to create Nagios timeperiod definitions. This also enables the Multiadmin tools to filter out services which are currently not in their notification interval.
• NIC check for Linux (netctr.combined) now supports checking of error rates
• fc_brocade_port: New possibility of monitoring CRC errors and C3 discards
• Fixed bug: snmp_info_single was missing in precompiled host checks

New in version 1.0.38

Changes

• New: check_mk's multiadmin tool (Python based web page). It allows mass administration of services (enable/disable checks/notifications, acknowledgements, downtimes). It does not need Nagios service- or host groups but works with a freeform search.
• Remove duplicate <?php from the four new PNP templates of 1.0.37.
• Linux Agent: Kill hanging NFS with signal 9 (signal 15 does not always help)
• Some improvements in autodetection. Also make debug mode: ./autodetect.py: This helps to find problems in autodetection.
• New configuration variables generate_hostconf and generate_dummy_commands, which allows to suppress generation of host definitions for Nagios, or dummy commands, resp.
• Now also SNMP based checks use cache files.
• New major options --backup and --restore for intelligent backup and restore of configuration and runtime data
• New variable simulation_mode allows you to dry run your Nagios with data from another installation.
• Fixed inventory of Linux cpu.loads and cpu.threads
• Fixed several examples in checks manpages
• Fixed problems in install_nagios_on_lenny.sh
• ./setup.sh now understands option --yes: This will not output anything except error messages and assumes 'yes' to all questions
• Fix missing 'default.php' in templates for local

New in version 1.0.37

Changes

• IMPORTANT: Semantics of check "cpu.loads" has changed. Levels are now regarded as *per CPU*. That means, that if your warning level is at 4.0 on a 2 CPU machine, then a level of 8.0 is applied.
• On check_mk -v now also ouputs version of check_mk
• logfile_patterns can now contain host specific entries. Please refer to updated online documentation for details.
• Handling wrapping of performance counters. 32 and 64 bit counters should be autodetected and handled correctly. Counters wrapping over twice within one check cycle cannot be handled, though.
• Fixed bug in diskstat: Throughput was computed twice too high, since /proc/diskstats counts in sectors (512 Bytes) not in KB
• The new configuration variables bulkwalk_hosts and non_bulkwalk_hosts, that allow to specify, which hosts support snmpbulkwalk (which is faster than snmpwalk) and which not. In previos versions, always bulk walk was used, but some devices do not support that.
• New configuration variable non_aggregated_hosts allows to exclude hosts generally from service aggregation.
• New SNMP based check for Rittal CMC TC (ComputerMultiControl-TopConcept) Temperature sensors
• Fixed several problems in autodetection of setup
• Fixed inventory check: exit code was always 0 for newer Python versions.
• Fixed optical problem in check manual pages with newer version of less.
• New template check_mk-local.php that tries to find and include service name specific templates. If none is found, default.php will be used.
• New PNP templates check_mk-kernel.php for major page faults, context switches and process creation
• New PNP template for cpu.threads (Number of threads)
• Check nfsmounts now detects stale NFS handles and triggers a warning state in that case

New in version 1.0.36

Changes

• New feature of Linux/UNIX Agent: "MRPE" allows you to call Nagios plugins by the agent. Please refer to online documentation for details.
• Fix bug in logwatch.php: Logfiles names containing spaces now work.
• Setup.sh now automatically creates cfg_dir if none found in nagios.cfg (which is the case for the default configuration of a self compiled Nagios)
• Fix computation of CPU usage for VMS.
• snmp_hosts now allows config-list syntax. If you do not define snmp_hosts at all, all hosts with tag 'snmp' are considered to be SNMP hosts. That is the new preferred way to do it. Please refer to the new online documentation.
• snmp_communities now also allows config-list syntax and is compatible to datasource_programs. This allows to define different SNMP communities by making use of host tags.
• Check ifoperstatus: Monitoring of unused ports is now controlled via ifoperstatus_monitor_unused.
• Fix problem in Windows-Agent with cluster filesystems: temporarily non-present cluster-filesystems are ignored by the agent now.
• Linux agent now supports /dev/cciss/d0d0... in section <<<diskstat>>>
• host configuration for Nagios creates now a variable 'name host_' for each host. This allows you to add custom Nagios settings to specific hosts in a quite general way.
• hosts' parents can now be specified with the variable 'parents'. Please look at online documentation for details.
• Summary hosts now automatically get their real host as a parent. This also holds for summary cluster hosts.
• New option -X, --config-check that checks your configuration for invalid variables. You still can use your own temporary variables if you prefix them with an underscore. IMPORTANT: Please check your configuration files with this option. The check may become an implicit standard in future versions.
• Fixed problem with inventory check on older Python versions.
• Updated install_nagios_on_lenny.sh to Nagios version 3.2.0 and fixed several bugs.

New in version 1.0.35

Changes

• New option -R/--restart that does -S, -H and -C and also restarts Nagios, but before that does a Nagios config check. If that fails, everything is rolled back and Nagios keeps running with the old configuration.
• PNP template for PING which combines RTA and LOSS into one graph.
• Host check interval set to 1 in default templates.
• New check for hanging NFS mounts (currently only on Linux)
• Changed check_mk_templates.cfg for PING-only hosts: No performance data is processed for the PING-Check since the PING data is already processed via the host check (avoid duplicate RRDs)
• Fix broken notes_url for logwatch: Value from setup.sh was ignored and always default value taken.
• Renamed config variable mknagios_port to agent_port (please updated main.mk if you use that variable)
• Renamed config variable mknagios_min_version to agent_min_version (update main.mk if used)
• Renamed config variable mknagios_autochecksdir to autochecksdir (update main.mk if used)
• configuration directory for Linux/UNIX agents is now configurable (default is /etc/check_mk)
• Add missing configuration variable to precompiled checks (fix problem when using clusters)
• Improved multipath-check: Inventory now determines current number of paths. And check output is more verbose.
• Mark config files as config files in RPM. RPM used to overwrite main.mk on update!

New in version 1.0.34

Changes

• Ship agents for AIX and SunOS/Solaris (beta versions).
• setup script now autodetects paths and settings of your running Nagios
• Debian package of check_mk itself is now natively build with paths matching the prepackaged Nagios on Debian 5.0
• checks/df: Fix output of check: percentage shown in output did include reserved space for root where check logic did not. Also fix logic: account reserved space as used - not as avail.
• checks/df: Exclude filesystems with size 0 from inventory.
• Fix bug with host tags in clusters -> precompile did not work.
• New feature "Inventory Check": Check for new services. Setting inventory_check_interval=120 in main.mk will check for new services every 2 hours on each host. Refer to online documentation for more details.
• Fixed bug: When agent sends invalid information or check has bug, check_mk now handles this gracefully
• Fixed bug in checks/diskstat and in Linux agent. Also IDE disks are found. The inventory does now work correctly if now disks are found.
• Determine common group of Apache and Nagios at setup. Auto set new variable www_group which replaces logwatch_groupid. Fix bug: logwatch directories are now created with correct ownership when check_mk is called manually as root.
• Default templates: notifications options for hosts and services now include also recovery, flapping and warning events.
• Windows agent: changed computation of RAM and SWAP usage (now we assume that "totalPageFile" includes RAM *and* SWAP).
• Fix problem with Nagios configuration files: remove characters Nagios considers as illegal from service descriptions.
• Processing of performance data (check_icmp) for host checks and PING-only-services now set to 1 in default templates check_mk_templates.cfg.
• New SNMP checks for querying FSC ServerView Agent: fsc_fans, fsc_temp and fsc_subsystems. Successfully tested with agents running on Windows and Linux.
• RPM packaged agent tested to be working on VMWare ESX 4.0 (simply install RPM package with rpm -i ... and open port in firewall with "esxcfg-firewall -o 6556,tcp,in,check_mk")
• Improve handling of cache files: inventory now uses cache files only if they are current and if the hosts are not explicitely specified.

New in version 1.0.33

Changes

• Made check_mk run on Python 2.3.4 (as used in CentOS 4.7 und RedHat 4.7).
• New option -M that prints out manual pages of checks. Only a few check types are documented yet, but more will be following.
• Package the empty directory /usr/lib/check_mk_agent/plugins and ../local into the RPM and DEB package of the agent
• New feature: service_dependencies. check_mk lets you comfortably create Nagios servicedependency definitions for you and also supports them by executing the checks in an optimal order.
• logwatch.php: New button for hiding the context messages. This is a global setting for all logfiles and its state is stored in a cookie.

New in version 1.0.32

Changes

• IMPORTANT: Configuration variable datasource_programs is now analogous to that of host_groups. That means: the order of program and hostlist must be swapped!
• New option --fake-dns, useful for tests with non-existing hosts.
• Massive speed improvement for -S, -H and -C
• Fixed bug in inventory of clusters: Clustered services where silently dropped (since introduction of host tags). Fixed now.
• Fixed minor bug in inventory: Suppress DNS lookup when using --no-tcp
• Fixed bug in cluster handling: Missing function strip_tags() in check_mk_base.py was eliminated.
• Changed semantics of host_groups, summary_host_groups, host_contactgroups, and summary_host_groups for clusters. Now the cluster names will be relevant, not the names of the nodes. This allows the cluster hosts to have different host/contactgroups than the nodes. And it is more consistent with other parts of the configuration.
• Fixed bug: datasource_programs on cluster nodes did not work when precompiling

New in version 1.0.31

Changes

• New option -D, --dump that dumps all configuration information about one, several or all hosts New config variables 'ignored_checktypes' and 'ignored_services', which allow to include certain checktypes in general or some services from some hosts from inventory
• Config variable 'clustered_services' now has the same semantics as ignored_checktypes and allows to make it host dependent.
• Allow magic tags PHYSICAL_HOSTS, CLUSTER_HOSTS and ALL_HOSTS at all places, where lists of hosts are expected (except checks). This fixes various problems that arise when using all_hosts at

those places

• all_hosts might by changed by another file in conf.d
• all_hosts does not contain the cluster hosts
• Config file 'final.mk' is read after all other config files - if it exists. You can put debug code there that prints the contents of your variables.
• Use colored output only, if stdout is a tty. If you have problems with colors, then you can pipe the output through cat or less
• Fixed bug with host tags: didn't strip off tags when processing configuration lists (occurs when using custom host lists)
• mk_logwatch is now aware of inodes of logfiles. This is important for fast rotating files: If the inode of a logfile changes between two checks mk_logwatch assumes that the complete content is new, even if the new file is longer than the old one.
• check_mk makes sure that you do not have duplicate hosts in all_hosts or clusters.

New in version 1.0.30

Changes

• Windows agent now automatically monitors all existing event logs, not only "System" and "Application".

New in version 1.0.29

Changes

• Improved default Nagios configuration file: added some missing templates, enter correct URLs asked at setup time.
• IMPORANT: If you do not use the new default Nagios configuration file you need to rename the template for aggregated services (summary services) to check_mk_summarizes (old name was 'check_mk_passive-summary'). Aggregated services are *always* passive and do *never* have performance data.
• Hopefully fixed CPU usage output on multi-CPU machines
• Fixed Problem in Windows Agent: Eventlog monitoring does now also work, if first record has not number 1 (relevant for larger/older eventlogs)
• Fixed bug in administration.html: Filename for Nagios must be named check_mk.cfg and *not* main.mk. Nagios does not read files without the suffix .cfg.
• magic factor for df, that allows to automatgically adapt levels for very big or very small filesystems.
• new concept of host tags simplyfies configuration.
• IMPORTANT: at all places in the configuration where lists of hosts are used those are not any longer interpreted as regular expressions. Hostnames must match exactly. Therefore the list [ "" ] does not any longer represent the list of all hosts. It is a bug now. Please write all_hosts instead of [ "" ]. The semantics for service expressions has not changed.
• Fixed problem with logwatch.php: Begin with <?php, not with <?. This makes some older webservers happy.
• Fixed problem in check ipmi: Handle corrupt output from agent
• Cleaned up code, improved inline documentation
• Fixed problem with vms_df: default_filesystem_levels, filesystem_levels and df magic number now are used for df, vms_df and df_netapp together. Works now also when precompiled.

New in version 1.0.28

Changes

• IMPORTANT: the config file has been renamed from check_mk.cfg to main.mk. This has been suggested by several of my customers in order to avoid confusion with Nagios configuration files. In addition, all check_mk's configuration file have to end in '.mk'. This also holds for the autochecks. The setup.sh script will automatically rename all relevant files. Users of RPM or DEB installations have to remove the files themselves - sorry.
• Windows agent supports eventlogs. Current all Warning and Error messages from 'System' and 'Application' are being sent to check_mk. Events can be filtered on the Nagios host.
• Fixed bug: direct RRD update didn't work. Should now.
• Fixed permission problems when run as root.
• Agent is expected to send its version in <<<check_mk>>> now (not any longer in <<<mknagios>>>
• Fixed bug in Windows agent. Performance counters now output correct values
• Change checks/winperf: Changed 'ops/sec' into MB/s. That measures read and write disk throughput (now warn/crit levels possible yet)
• new SNMP check 'ifoperstatus' for checking link of network interfaces via SNMP standard MIB
• translated setup script into english
• fixed bug with missing directories in setup script
• made setup script's output nicer, show version information
• NEW: mk_logwatch - a new plugin for the linux/UNIX agent for watching logfiles
• Better error handling with Nagios pipe
• Better handling of global error: make check_mk return CRIT, when no data can retrieved at all.
• Added missing template 'check_mk_pingonly' in sample Nagios config file (is needed for hosts without checks)

New in version 1.0.27

Changes

• Ship source code of windows agent
• fix several typos
• fix bug: option --list-hosts did not work
• fix bug: precompile "-C" did not work because of missing extension .py
• new option -U,--update: It combines -S, -H and -U and writes the Nagios configuration into a file (not to stdout).
• ship templates for PNP4Nagios matching most check_mk-checks. Standard installation path is /usr/share/check_mk/pnp-templates - Changed License to GNU GPL Version 2

New in version 1.0.26

Changes

• modules check_mk_admin and check_mk_base are both shipped uncompiled.
• source code of windows agent togehter with Makefile shipped with normal distribution
• checks/md now handles rare case where output of /proc/mdstat shows three lines per array

New in version 1.0.25

Changes

• setup skript remembers paths

New in version 1.0.24

Changes

• fixed bug with precompile: Version of Agent was always 0

New in version 1.0.23

Changes

• fixed bug: check_config_variables was missing in precompiled files
• new logwatch agent in Python plus new logwatch-check that handles both the output from the old and the new agent

New in version 1.0.22

Changes

• Default timeout for TCP transfer increased from 3.0 to 60.0
• Windows agent supports '<<<mem>>>' that is compatible with Linux
• Windows agents performance counters output fixed
• Windows agent can now be cross-compiled with mingw on Linux
• New checktype winperf.cpuusage that retrieves the percentage of CPU usage from windows (still has to be tested on Multi-CPU machine)
• Fixed bug: logwatch_dir and logwatch_groupid got lost when precompiling.
• arithmetic for CPU usage on VMS multi-CPU machines changed

New in version 1.0.21

Changes

• fixed bug in checks/df: filesystem levels did not work with precompiled checks

New in version 1.0.20

Changes

• new administration guide in doc/
• fixed bug: option -v now works independent of order
• fixed bug: in statgrab_net: variable was missing (affected -C)
• fixed bug: added missing variables, imported re (affected -C)
• check ipmi: new option ipmi_summarize: create only one check for all sensors
• new pnp-template for ipmi summarized ambient temperature

New in version 1.0.19

Changes

• Monitoring of Windows Services
• Fixed bug with check-specific default parameters
• Monitoring of VMS (agent not included yet)
• Retrieving of data via an external programm (e.g. SSH/RSH)
• setup.sh does not overwrite check_mk.cfg but installs the new default file as check_mk.cfg-1.0.19
• Put hosts into default hostgroup if none is configured
