Build 205

2021-08-05

Self-hosted Operator Release Notes

Minimum version to update from directly: Build 201

NOTE: The operator has been substantially reworked internally. This will make build 205 a required release that cannot be skipped.

  • This release introduces Elasticsearch 7. Please ensure the availability of an Elasticsearch 7.10.2 cluster. If you are using our single-box database setup, the only thing required is to update that setup.
  • The operator now installs Kubernetes NetworkPolicies that limit egress and ingress traffic
    between Instana components to what is required for the system to work.
  • The operator now takes care of propagating Secrets to Unit namespaces. Secrets must only be created/updated in Core namespaces. Manual changes to Secrets in Unit namespaces are overwritten and won't have any effect. Changes to Secrets are automatically recognized by the operator which will then update the system as necessary.
  • The Kubernetes cluster domain is now configurable.

Cumulative Changes since Release #201

Agent: Configuration from Process specific files - provide YAML subtrees

In addition to the already available process specific configuration from file or environment with YAML literals, the host agent now supports YAML subtrees from process specific files. This allows for complex configurations, like Java JMX, to be customized for individual processes when running inside containers. Check out the host agent documentation for details.

Custom payload in alert configurations

Instana now provides support to enrich specific alert with static key-value pairs which would be attached to the alert notification.

IBM i and Db2 on i monitoring

Instana now supports remote monitoring of multiple IBM i instances. The monitored IBM i instance will be displayed as a tower on your Infrastructure Map as well as the Db2 on i will be presented as a running process within the tower. OS related metrics are collected from various system tables, as well as the database related metrics are collected using the built-in IBM i Collection Services. The supported versions are: 7.2, 7.3 and 7.4.

This includes:

  • IBM i OS level metrics - a built-in dashboard that displays system and memory pool metrics. For more information, refer to the IBM i docs.
  • Db2 on i - a built-in dashboard that displays Active Queries, various Operations, Plan Cache and SQL Cursor metrics. For more information, refer to the Db2 on i docs.

IBM APM V8 integration support

Instana now supports integration with IBM Application Performance Monitoring V8. Supported V8 agents attached to an APM V8 server can be integrated with the Instana server. Metrics and identity information from the APM V8 agents is forwarded to the Instana server. Host, process and IBM Datapower entities and metrics will appear on the Infrastructure map. Supported V8 agents are:

  • Linux OS
  • Window OS
  • Unix OS on AIX
  • IBM Datapower

IBM MQ tracing support (Technology Preview)

Instana now supports tracing IBM MQ messages on xLinux 64. For more information, refer to the IBM MQ docs.

IBM Z HMC monitoring (Technology Preview)

Instana now supports remote monitoring of zHMC. This includes a built-in dashboard that displays key metrics. For more information, refer to the IBM Z HMC docs

Instana Agent on OpenShift

The Instana Agent can now be deployed on OpenShift 4.7 and above on IBM Z and LinuxONE. We made sure to cover all 3 modes of installation - Helm, YAML and Operator.

Find our more on in our OpenShift documentation.

Sensor and Agent enhancements

  • WebSphere Application

    • Added EJB metrics ResponseTime and ResponseCount
    • Added session manager metrics CreateCount and InvalidateCount
    • Added thread pool metrics ConcurrentHungThreadCount and DeclaredThreadHungCount
  • IBM Db2 v 11.5 LUW Containerised version with agents running on Linux VMs - Supported on Linux on x86_64, Linux on Power, IBM Z and LinuxONE

    • Added various metrics related to Top queries, Lock wait, Agent status, DBM Config usage, workload and UOW as metrics collections.
    • Added detailed table views for DB & DBM configurations, Top Queries, Lock wait, Top Total CPU, Log Disk Wait, Runstats and Diag Log entries.
  • With Agent 1.1.602 its possible to set mode.web-override.allowed = false in the file <agent-installation>/etc/instana/com.instana.agent.main.config.Agent.cfg to disable the possibility of overriding the Agent Mode directly from the Instana UI.

Localization

You can now inspect the Instana product in nine additional languages. While we aren't finished yet with the product's localization (see known issues), we hope you can already benefit from this. The language can be configured within the product's general user settings (Settings ➡ User Settings ➡ General). With this release, we are supporting the following languages:

  • Chinese (China),
  • Chinese (Taiwan),
  • English,
  • French,
  • German,
  • Italian,
  • Japanese,
  • Korean,
  • Portuguese (Brazil), and
  • Spanish.

Custom events

An additional system rule has been added in order to ensure the presence (and be notified in the absence) of hosts. This rule can be found under "System Rules" with the name "Host availability detection".

Improvements

  • Go: versions v1.29.0, instrumentation/instalambda/v1.3.0, instrumentation/instaawssdk/v1.1.0 were released. Support for a direct AWS Lambda invocation was added.
