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

by Lars Michelsen

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 11125: f5_bigip_mem: Fix discovery of service

by Jonas Kluger

ID: 11125 Title: f5_bigip_mem: Fix discovery of service Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 The service sometimes got falsely discovered. It will now only be discovered if both OID and a value are present.

Checkmk Werk 11073: NagVis snapin: Fix empty content during refresh

by Lars Michelsen

ID: 11073 Title: NagVis snapin: Fix empty content during refresh Component: Multisite Level: 1 Class: Bug fix Version: 1.7.0i1 When the NagVis snapin is used with a larger number of maps or objects on these maps, the refresh of the map states takes some time. During longer refresh times, the snapin was not displaying the maps at all. The already known state is now shown during refresh until the new information is available.

Checkmk Werk 10907: ucd_cpu_util: Fix CPU utilization calculation

by Jonas Kluger

ID: 10907 Title: ucd_cpu_util: Fix CPU utilization calculation Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 Fixed the calculation for the CPU utilization. The system value used the outdated values/OIDs. No longer query the CpuRawKernel value, since its already included in the CpuRawSystem. CpuRawSystem = CpuRawKernel + CpuRawWait The system value gets computed as: system = CpuRawSystem + CpuRawInterrupt + CpuRawSoftIRQ (CpuRawInterrupt in this case is equal to IRQ)

Checkmk Werk 11072: Distributed environments: Improve config synchronization

by Lars Michelsen

ID: 11072 Title: Distributed environments: Improve config synchronization Component: WATO Level: 3 Class: New feature Version: 1.7.0i1 Synchronizing configurations between the central and remote sites has taken too much time in the past because the entire configuration was always synchronized. Even files that are still present on the remote site were completely synchronized, which led to increased computing effort, traffic and runtime. This mechanism has now been replaced by an incremental mechanism. Before each synchronization, the system determines which files already exist on the remote site. Only those files are synchronized that differ from the central site. For the migration from Checkmk 1.6 to 1.7 the change is compatible. Both central 1.6 sites can communicate with remote 1.7 sites and 1.7 central sites can communicate with 1.6 remote sites. Mixed environments should only be used for migration purposes. In such a scenario, the previous synchronization mechanism is used. After 1.7 this compatibility mode will be removed.

Checkmk Werk 10988: Periodic service discovery: Fix not working "rediscovery scheduled" on clusters

by Simon Jess

ID: 10988 Title: Periodic service discovery: Fix not working "rediscovery scheduled" on clusters Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 Please note that if you have configured rules {{Periodic service discovery}} for clusters then the service discovery is executed on the cluster nodes. This may overlap with rules of the nodes.

Checkmk Werk 11093: aws_cloudwatch_alarms_limits: fix discovery

by Joerg Herbel

ID: 11093 Title: aws_cloudwatch_alarms_limits: fix discovery Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 This werk fixes an issue with the discovery of the service aws_cloudwatch_alarms_limits, which was never discovered, even if the AWS special agent was configured accordingly. This service monitors the number of AWS CloudWatch alarms.

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 11104: heartbeat_crm: go to CRIT if data is too old

by Moritz Kiemer

ID: 11104 Title: heartbeat_crm: go to CRIT if data is too old Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 The service previously went to UNKNOWN instead of CRIT.
