Control Center Adds Cache Monitoring, Tracing, and More for Apache Ignite

Since our initial launch in mid-2020, GridGain Control Center has strived to bring transparency and flexibility to the monitoring and development of Apache Ignite and GridGain applications. With each monthly update, we introduce new features to make it easier for admins and developers to understand what exactly is happening within their clusters. In our latest update (2020.11.00), we add new features for Cache monitoring, new API instrumentation for Tracing, and new security integrations.

I will be doing a training session on how to manage and monitor Ignite with Control Center on January 20, 2021 at 10am PT. Please join the session to get a comprehensive, hands-on experience with the latest version of Control Center.

Caches View

While it has always been possible to build custom dashboards that display important Cache metrics, it required knowledge of which metrics to choose and how best to display them. The Cache view is a new top level feature which collects these metrics in a simpler layout and adds a new set of actions. With the Cache view, you can view the list of caches in the cluster, understand data partition distribution across the nodes, and track lost partitions in the event of a problem with the cluster. New actions have also been added for cache management including the ability to initiate a rebalance on a particular cache and options to clear data and delete caches from the cluster.

Tracing Improvements

To assist in debugging and performance analysis, Gridgain (and more recently Apache Ignite) introduced application tracing based on OpenCensus. As distributed applications scale horizontally to meet their performance needs, it can be tricky to track API calls as they traverse the nodes of the cluster. Control Center allows you to collect the individual API calls as span data and then combine the spans into a unified call stack, or trace.

New APIs have recently been instrumented to support tracing analysis including Transactions, Cache Read, and Cache Write operations. Being able to analyze the timing of individual steps in a transaction makes it easier to pinpoint bottlenecks in the execution stack. While this won’t fix an issue, it will give you a good idea of where to start looking during root cause analysis.

For a video demonstration of how to leverage tracing to identify bottlenecks in distributed operations running on a Ignite cluster, watch this video.

Control Center has also made it more convenient to enable and disable tracing by simply toggling data collecting for the API of interest. This gives you the power and flexibility to decide when you need to get that extra bit of debugging information and then turn off tracing collection as needed.

Single Sign On Integration

To make integration easier with on premise installations, Control Center added integration for OpenID Connect to make it easier to work with environments that use Single Sign On infrastructure. Through OpenID Connect, Control Center can support common identity providers such as; Okta, Google, Microsoft/Skype, and more.

What’s Next

Control Center continues to march on adding new features to simplify development for Apache Ignite and GridGain. In the coming months, you will see new ways to search and learn about the hundreds of metrics exposed from your clusters. You will have more options to organize metrics dashboards into reusable templates with sample templates focused on different topics like CPU, memory utilization, transactions, threading, and more. Also you will also see new options to integrate into existing infrastructure like LDAP and Active Directory.
