requests to deploy both application and infrastructure changes to Kubernetes. With the entire state of your cluster kept under source control, diff tools and synchronization agents can compare what’s to normal if needed. CANONICALLY VERSIONED DESIRED SYSTEM STATE Now, by being able to declaratively store your desired system state in Git, you can easily apply versioning — as one does to application system configuration state, i.e., infra config code present in Git. This makes rollbacks easier in case your desired state in Git results in system instability for your actual state present in the cluster

Kubernetes clusters using familiar patterns. A more refined way to manage configurations and declare the state of everything in a given Kubernetes cluster called GitOps is something that Christian embraced wholeheartedly them to return their entire platform (not just the workloads running on them) back to its original state. They essentially implemented infrastructure as code by keeping every- thing they wrote (including of APIs that uses state as a central point of deciding what and how to operate on something. Kubernetes controls the operating environment by comparing the declared (desired) state of an object to the

sensors. A new function band() (bitwise AND) and an improved function count() can be used for testing state of bits of discrete sensors. 5.4 Loadable modules Loadable modules, new in Zabbix 2.2, offer a way unsupported, but also when a low-level discovery rule becomes unsupported or a trigger goes into an unknown state. The benefit of having internal events is that users can configure actions based on these events zabbix[items] • zabbix[items_unsupported] • zabbix[java„] • zabbix[process,,,<state>] (alerter, db watchdog, escalator, node watcher, proxy poller, timer processes aren’t supported

can separately define the conditions that have to be met for the trigger to return back to the OK state. 10 There is also more control over how OK events are generated. You can use the problem expression expression as basis, or even select ’None’ in which case the trigger will always remain in problem state if it goes into it. Additionally, PROBLEM event generation mode for single/multiple problem events ”Event type” conditions for internal events - Item in “normal” state, Low-level discovery rule in “normal” state, Trigger in “normal” state 11 For more details, see: • Actions • Recovery operations

available, in the following format: • for map description:

(for trigger and internal events): • ’Problem’ value if the original event is still in problem state; • ’OK’ value if the original event has been resolved. 19 Low-level discovery • Support of LLD ’Problem’ state. When received data are below the threshold, triggers stay in/return to an ’Ok’ state. event - a single occurrence of something that deserves attention such as a trigger changing state or a which may even use a different data collection method. problem - a trigger that is in ”Problem” state. action - a predefined means of reacting to an event. An action consists of operations (e.g. sending

16 VMware monitoring improvements A new simple check to monitor VMware virtual machine CPU ready state was added. For more information see VMware monitoring item keys. 5.17 Context support in user macros information about a service. The service.info item should now be used instead of the deprecated service_state item. A new db.odbc.discovery item has been introduced to support low-level discovery using ODBC these modules not being loaded, the item will fall back on the old method of retrieving sockets by state via reading the /proc/net/tcp(6) file(s). The methodology for reading the /proc/net/tcp(6) file(s)
