Checkmk Werk 11092: One service per region for AWS limits

by Joerg Herbel

ID: 11092 Title: One service per region for AWS limits Component: Checks & agents Level: 1 Class: New feature Version: 1.7.0i1 With this werk, the monitoring of limits for AWS services is split into one service per region. Before, all regions were combined into a single service, which resulted in potentially quite a lot of output and caused problems with the graphs for 2 or more regions. To apply this werk, users have to re-discover the corresponding services, which will result in a loss of the historically recorded metrics. This is best done using "Automatic refresh (tabula rasa)" in the WATO-menus of the affected hosts. Note that rules for upper or lower levels created before this werk are not affected and will apply to all newly discovered services. After installing the werk, they can be modified to only apply to certain regions.

Checkmk Werk 10535: Activate Changes: Now able to specifiy the number of parallel site activations

by Andreas Boesl

ID: 10535 Title: Activate Changes: Now able to specifiy the number of parallel site activations Component: WATO Level: 1 Class: New feature Version: 1.7.0i1 Earlier versions may have run into memory problems when too much sites were activated at the same time. Each site was handled in a separate helper process. This consumed quite a lot of memory when your WATO setup included lots (>50) of sites. You can now configure how much helper processes are spawned during the activate changes phase. If there are more sites to activate then available helper processes, the remaining sites are put into a queue and will be processed once a helper process becomes idle again. Per default the optimal number of helper processes is calculated automatically (up to 90% remaining RAM is used), which should be OK for most setups. The new global settings option <tt>Maximum parallel processes during activate changes</tt> allows you to adjust this value. The hardcoded minium value is 5.

Checkmk Werk 11027: LDAP: Validate usage of suffix

by Ronny Bruska

ID: 11027 Title: LDAP: Validate usage of suffix Component: WATO Level: 1 Class: Bug fix Version: 1.7.0i1 If you configure multiple LDAP connections with the same suffix, the 'Users' page is broken and can not be accessed any more. From now on, you will be warned, if a suffix is already in use by another connection.

Checkmk Werk 10906: Extend UCD SNMP scan function

by Jonas Kluger

ID: 10906 Title: Extend UCD SNMP scan function Component: Checks & agents Level: 1 Class: New feature Version: 1.7.0i1 The UCD SNMP scan function got extended to detect devices without system description OID. This change allows to detect devices like Dell EMC ECS systems. For these special devices make sure to set the rule "Hosts without system description OID". However this should normally be avoided if possible.

Checkmk Werk 10987: HW/SW Inventory Service: Fix "State when inventory fails"

by Simon Jess

ID: 10987 Title: HW/SW Inventory Service: Fix "State when inventory fails" Component: HW/SW Inventory Level: 1 Class: Bug fix Version: 1.7.0i1 The state of the HW/SW Inventory service can be determined by {{State when inventory fails}} in the ruleset {{Do hardware/software Inventory}}. This state was overwritten by the following error cases: <ul> <li>Empty output, default CRIT</li> <li>Connection, default CRIT</li> <li>Timeout, default CRIT</li> <li>Exception, default UNKNOWN</li> </ul> This behaviour was introduced with 1.5.0 and and has been fixed now: The HW/SW Inventory service state won't be overwritten any more.

Checkmk Werk 11091: AWS monitoring: adjustments to werk #10962 and bugfixes

by Joerg Herbel

ID: 11091 Title: AWS monitoring: adjustments to werk #10962 and bugfixes Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 This werk adjusts the output several checks for AWS services. With werk #10962, the output of these checks changed from sums over some time period to actual rates, which can be interpreted by the user. This werk adjusts the output units and metrics of these checks accordingly: - aws_elb - aws_elbv2_application.connections - aws_elbv2_application.http_redirects - aws_elbv2_application.statistics - aws_elbv2_network.connections - aws_elbv2_network.rst_packets - aws_elbv2_network.statistics - aws_elbv2_network.tls_handshakes - aws_s3_requests.select_object - aws_s3_requests.traffic_stats Furthermore, for the following checks, the agent output has been adjusted to be in line with what the user expects (e.g. averages instead of sums for latencies, also partially connected to werk #10962). - aws_elbv2_application - aws_elbv2_network - aws_s3_requests.latency Finally, a few bugs, such as integer instead of floating output, have been fixed. Where necessary, rules and manpages have also been updated.
