Check_MK Werk 3037: Terminate datasource programs when check timeout occurs

by Lars Michelsen

ID: 3037 Title: Terminate datasource programs when check timeout occurs Component: Core & Setup Level: 2 Class: Bug Fix Version: 1.2.7i4 When using datasource programs, e.g. for checking by SSH, the Check_MK process could be terminated by a reached timeout leaving the launched subprocesses open. This might have caused in processes being too long open, running and consuming resources. The datasource program process and it's sub processes are now cleaned up when a check timeout occures.

Check_MK Werk 3036: Bulk discovery steps are now timing out short before HTTP request timeout

by Lars Michelsen

ID: 3036 Title: Bulk discovery steps are now timing out short before HTTP request timeout Component: WATO Level: 2 Class: Bug Fix Version: 1.2.7i4 The bulk discovery could cause stability issues by consuming too much resources on the monitoring server. This could be caused in case the single discovery steps take longer than the configured timeout of the web server service the Check_MK GUI. In case a request (discovery step) took longer than the request timeout, the browser request was timing out and the next discovery step was started while the former discovery process of Check_MK was still running. If this happened multiple times, like several hundret times, this could consume all system memory and causing a lot of CPU load which may result in an unstable monitoring server. Only a restart of the whole sites web server could fix this situation.

Check_MK Werk 2934: all temperature checks rewritten to use the shared temperature api

by Sebastian Herbord

ID: 2934 Title: all temperature checks rewritten to use the shared temperature api Component: Checks & Agents Level: 3 Class: New Feature Version: 1.2.7i4 Over 100 checks were touched in this update. For most of these checks it won't be necessary to re-inventorize but once you do, item names on many checks will change. Service descriptions have also been normalized but to ease the transition from existing setups, the old service description will continue to show on existing installations. If you have an existing installation and would like to switch to the new service descriptions you can toggle them in: Global Settings->Execution of checks->Use new service descriptions Finally, all temperature checks can now be configured through the same rule (called "Temperature", who would've thunk) and support the same features (like configurable unit, support for trend computations, upper and lower thersholds and so on). Unfortunately this means that most existing rules for temperature checks will no longer be applied and disappear from the Host&Service Parameter list. Please make sure you carry over all important temperature rules! You can still see the now deprecated rules through the button "Deprecated Rulesets" in Host&Service Parameters.

Check_MK Werk 2902: Hosts can now be added by regular network scans of configured IP ranges

by Lars Michelsen

ID: 2902 Title: Hosts can now be added by regular network scans of configured IP ranges Component: WATO Level: 2 Class: New Feature Version: 1.2.7i4 For each WATO folder a new attribute Network Scan can now be configured. This network scan will ping all IP addresses in all configured IP ranges in the configured interval for new reachable hosts / IP addresses. When such a network scan of a folder discovers a new host, the discovery mechanism tries to resolve the host name via DNS. If found, it uses the DNS name as hostname. Otherwise the IP address will be used as host name. Then it will be created as new host and added to this folder. Hosts found by the network scan are added as disabled host. You can enable monitoring of these hosts by setting the Criticality host tag of this host to another value. Additionally you may want to configure other attributes like the agent type of this host before adding it to your regular monitoring. If you want to exclude a found host from your monitoring, add the IP address to the list of excluded IP addresses and then delete the found host from this folder. The result of a network scan is written to the Last Scan Result attribute of a folder. So if you like to know when the last scan for a folder was performed, take a look at that folders properties. If you experience issues with the network scan, take a look at the log of the Web GUI (<tt>var/log/web.log</tt>).

Check_MK Werk 2882: Reorganize BI configuration into packs, add contacts and permissions

by Mathias Kettner

ID: 2882 Title: Reorganize BI configuration into packs, add contacts and permissions Component: BI Level: 2 Class: New Feature Version: 1.2.7i4 The WATO module for configuring Business Intelligence (BI) has been reorganized. The configuration is now split up into Packs. This has been made for two reasons: LI:It makes the configuration of large BI environments easier LI:It allows to delegate BI configuration to normal users Each pack contains rules and aggregations. A rule or aggregation in one pack can refer to rules in another pack. Each BI pack can have a list of contact groups. A new permission has been introduced: Business Intelligence Rules and Aggregations. Per default this is set for normal users. It allows a normal user to configure rules and aggregations in a BI pack if that user is in one of the listed contact groups of that pack. A pack can have the checkbox Allow all users to refer to rules contained in this pack set. That way a user can use rule from a pack where he is not a contact for. So the admin can put some basic rules there that can be used but not changed by other. Your existing BI configuration will automatically be converted the next time you use the WATO Bi modul. All existing rules and aggregations will be put in to one BI pack with the name Default Pack.

Check_MK Werk 2900: Bulk Host import can now handle CSV files including several host attributes

by Lars Michelsen

ID: 2900 Title: Bulk Host import can now handle CSV files including several host attributes Component: WATO Level: 2 Class: New Feature Version: 1.2.7i4 The Bulk Host Import feature of WATO could be used for importing a list of host names before. But more complex imports like adding hosts together with a collection of initial attributes was not possible. The import has now been extended that one can upload whole CSV files or paste the contents of a CSV file into a form. Then, after the upload, a preview page is displayed to configure the parameters how to parse the CSV file and which column to assign to which host attribute.

Check_MK Werk 2897: Changed move host action to be an action icon using a popup menu

by Lars Michelsen

ID: 2897 Title: Changed move host action to be an action icon using a popup menu Component: WATO Level: 2 Class: New Feature Version: 1.2.7i4 The "move host" action in the host configuration lists has been changed to be an action icon just like the other host actions. When you have a confiuration with a large folder hierarchy like hundrets of folders, this change will increase the rendering time of the hosts lists a lot.
