What are the 4 parts included in the plugin.json definition for ActiveGate plugins? Metadata, UI, Metrics, Configuration How are ActiveGate plugins licensed? The plugin SDK is free. Dynatrace partners can develop plugin for you, will depend on contract. Whatever custom metrics are used will be charged. How frequently do ActiveGate plugins execute? Once per minute Can you run multiple endpoints in a single ActiveGate plugin module? Yes What kind of ActiveGate executes ActiveGate plugins? Environment ActiveGate Can you execute ActiveGate plugins using an Environment ActiveGate that's configured for multi- environment support? No Where can you view results from plugin-monitoring? Technology overview page What is a "device group"? A technology tile that derives its data from an ActiveGate plugin. Why would you set up "key metrics" for an ActiveGate plugin? Define important metrics to be displayed in technology overview page.
What is the favicon property in the plugin.json definition? Allows you to define your own custom icon for device groups! What can device groups represent? Clusters, regions, groups of servers, etc. What is a custom device group entity? Bind metrics and properties to monitor device group metrics How do you define the type and look of charts of ActiveGate plugins? plugin.json What is pgmetrics in plugins.json for ActiveGate plugins? Section that allows you to define custom device metrics. Does Dynatrace AI baseline the metrics of your custom devices? Yes! How does Dynatrace create problems from custom devices (ActiveGate plugin)? Metric threshold violation in JSON definition. (Automatically sends events, not problems) How do you manually generate problems for your ActiveGate plugins? Python API - raise performance, availability, error, and resource contention problems Does Dynatrace automatically distribute plugins between Dynatrace server and ActiveGates? No, you need to deploy them on ActiveGate and upload them to server. In general, what is the point of plugins.json (ActiveGate plugins)? Define how data is presented in the Dynatrace UI.
If you're distributing managed cluster nodes across separate data centers, what is the max amount of nodes that Dynatrace recommends per data center? No more than 2 nodes per data center If you're distributing managed cluster nodes across separate data centers, what is the min amount of data centers that Dynatrace recommends? At least 3 data centers (1 can fail) Why does Dynatrace recommend that each managed cluster node be deployed on a separate physical disk? To prevent loss of monitoring data. Why does Dynatrace recommend deploying managed cluster nodes on systems with the same hardware characteristics? To minimize performance loss What should you keep in mind when building your manged cluster? Build cluster with additional capacity and possible node failure in mind. What happens when a managed cluster node fails? NGINX automatically load balances and redirects all OneAgent traffic to the remaining working nodes. Why would you use Dynatrace Managed deployment scenario 1: Basic setup? If you want your managed cluster to only be accessible internally. Why would you use Dynatrace Managed deployment scenario 2: Pure Dynatrace Managed setup? If you want to enable DEM services and communication from external sources. Why would you use Dynatrace Managed deployment scenario 3: integration with existing IT landscape? When customer already has environment with load balancers and proxies in place.
In Dynatrace Managed deployment scenario 1: basic setup, is remote access to Mission Control enabled? Yes In Dynatrace Managed deployment scenario 1: basic setup, what is each communication channel secured with? TLS (Transport layer security) Is a Cluster ActiveGate required for Dynatrace Managed deployment scenario 2: Pure Dynatrace Managed setup? Yes. It needs a publicly available IP address, a domain name with a valid SSL certificate, and the domain must be different from web UI domain. How many Cluster ActiveGates are recommended for high-load production-ready installations with external hosts, apps, sessions and synthetic monitoring? 2 Cluster ActiveGates are recommended with the same domain name and certificate What are the steps to take to use an Environment ActiveGate and a Cluster ActiveGate?
- Set up Dynatrace Manged cluster
- Set up Cluster ActiveGate, make sure it can connect with Dyantrace Manged cluster. Make sure Cluster ActiveGate has public IP address.
- Set up Environment ActiveGate and provide Cluster ActiveGate public address for external communication. Is CMC web UI traffic accessed using HTTP or HTTPS? HTTPS
What resources must be made exclusively available for Dynatrace in a managed cluster node? CPU and RAM Can managed cluster node CPUs have power saving mode enabled? No, power saving mode must be disabled What is the minimum CPU clock speed of a manged cluster node? 2GHz What is the minimum amount of RAM a managed cluster node should have? 32 GB How is storage done in multi-node clusters? Storage per node is divided by the number of nodes. Do we recommend Dynatrace binaries and data store to be on the same mount point in Dynatrace Managed? No - separate mount points to allow the data store to be resized independently. Do we recommend keeping Dynatrace data storage on the root volume in Dynatrace Managed? No, avoid additional complexity when resizing disk later, if required
Does Dynatrace recommend creating resizable disk partitions for Dynatrace Managed? Yes (e.g. Logical Volume Manager) Is OneAgent self-monitoring enabled by default for Dynatrace Managed? Yes, an opt-out installation parameter is available What operating systems can a managed cluster node be? All nodes must be on same Linux distribution. Do we recommend all managed cluster nodes to have the same hardware configuration? Yes Do we recommend that all managed cluster nodes are synchronized with NTP? Yes Do we recommend all managed cluster nodes to be in the same time zone? Yes Can you install Dynatrace Managed on a 32 bit Linux distribution? No, you must install Dynatrace Managed on a 64 bit Linux distribution. Can you install Dynatrace Managed on a virtualized host? Yes
Once after first startup What registration data do Managed Clusters send to Mission Control? License key, cluster ID What registration data does Mission Control send to Managed Clusters? Registration status, username, password How frequently is license data exchanged between Managed Clusters and Mission Control? Once every 5 minutes What license data do Managed Clusters send to Mission Control? Nothing! What license data does Mission Control send to Managed Clusters License status, cluster ID, license key, license details, license model. How frequently is health check data exchanged between Managed Clusters and Mission Control? Once every 5 minutes What health check data do Managed Clusters send to Mission Control? Cluster ID, privacy settings, time zone, traffic size, update/maintenance window, each cluster node adds OS name and version, number of CPU cores, CPU load, total RAM, free RAM, total disk storage, used disk storage, server state, master node flag (true/false), startup time stamp, each cluster ActiveGate adds version, OS name and version, certificate issuer, type (e.g. beacon forwarder)
What health check data does Mission Control send to Managed Clusters? Health status, message How frequently is consumption data exchange between Mission Control and Managed Clusters? Once every hour What consumption data do Managed Clusters send to Mission Control? Cluster ID, consumption timeframe, each environment adds number of new problems, number of RUM sessions, number of synthetic monitors, each host adds category, list of monitored technologies, monitored timeframes, each synthetic monitor adds ID, description, type, success count, failure count, action count What consumption data does Mission Control send to Managed Clusters? Status, remaining RUM sessions, consumed RUM overage, host units overage, remaining synthetic monitors, consumed synthetic monitors overage, for each environment: id, consumed RUM sessions, consumed synthetic monitors, host units. How frequently is heartbeat data exchanged between Managed Clusters and Mission Control? Once every minute, or every 5 minutes if remote access is disabled. What heartbeat data do Managed Clusters send to Mission Control? Cluster ID, node ID, source type (e.g. server) What heartbeat data does Mission Control send to Managed clusters?
