You'll see the term BPF in Linux source code, and you'll see BPF and eBPF used interchangeably in tooling and documentation.
They collect data from multiple sources through real user monitoring , synthetic monitoring, network monitoring, and application performance monitoring systems. The time from browser request to the first byte of information from the server. The time taken to complete the page load. Time to first byte. Time to render. Visually complete.
The possible navigation types are: Navigate: A hard navigation that resulted in an HTML page being fetched from the network. Navigate 70% of page views are Navigations , which means a user landed on them via a hard navigation and the file was fetched from the network. Cache: An HTML response returned from the HTTP cache.
In this case, the server appears to be continuously building responses, which is an expensive operation that indicates either we have a bug in the revision calculation of our message handler, or the list of ActiveGates is constantly changing, forcing frequent revision recalculation.
Since December 10, days after a critical vulnerability known as Log4Shell was discovered in servers supporting the game Minecraft, millions of exploit attempts have been made of the Log4j 2 Java library, according to one team tracking the impact, with potential threat to millions more applications and devices across the globe. Dynatrace news.
Concatenating our files on the server: Are we going to send many smaller files, or are we going to send one monolithic file? Compressing them over the network: Which compression algorithm, if any, will we use? Connection One thing we haven’t looked at is the impact of network speeds on these outcomes. Client There’s a fifth C !
Puppet software can be used to automate the management and configuration of your servers, including instrumentation for Dynatrace monitoring. The Dynatrace Puppet module is a natural next step in our support for automated server management and configuration. Why waste time on something that can be automated or scripted?
Rethinking Server-Timing As A Critical Monitoring Tool. Rethinking Server-Timing As A Critical Monitoring Tool. In the world of HTTP Headers, there is one header that I believe deserves more air-time and that is the Server-Timing header. Setting Server-Timing. Sean Roberts. 2022-05-16T10:00:00+00:00.
I can reload the exact same page under the exact same network conditions over and over, and I can guarantee I will not get the exact same, say, DOMContentLoaded each time. What if another file on the critical path had dropped out of cache and needed fetching from the network? There are myriad reasons for this that I won’t cover here.
With PowerConnect, collecting data from SAP systems and fueling the Dynatrace platform, Dynatrace automatically uncovers the topology model of the SAP landscape, providing a clear and comprehensive view of the relationships and dependencies among different systems, servers, databases, applications, and interfaces.
Dynatrace dashboards serve as a single pane of glass for monitoring artifacts like metrics, logs, events, user sessions, and server-side traces. Important : In Dynatrace Managed environments, you need to configure an additional Network scope setting. What you get with this update.
Migrating to cloud-based operations from a traditional on-premises networked system also requires artificial intelligence and end-to-end observability of the full software stack. Software factories: integrating AI to standardize cloud monitoring.
Let’s walk through the steps involved in installing and configuring the Prometheus server to store and display the metrics, an exporter (MySQL Exporter in this case) to collect the metrics and relay them to the Prometheus server, and Grafana to create dashboards. Prometheus requires an exporter for collecting MySQL server metrics.
Some aspects are just easy to grasp as they are well defined in the operator custom resources and documentation, but some are often considered to be a hidden craft. Network exposure in cases of sharded clusters is quite straightforward, […]
In this blog, we will discuss both data and network-level compression offered in MongoDB. We will discuss snappy and zstd for data block and zstd compression in a network. Percona Server for MongoDB (PSMDB) supports all types of compression and enterprise-grade features for free. I am using PSMDB 6.0.4
The value of SBM, as explained in the MySQL documentation , depends on the state of the MySQL slave in general, and the states of MySQL slave SQL_THREAD and IO_THREAD in particular. Lastly, it’s important to note that in our discussions so far, we have not assumed any network bottlenecks. Possible Values of Seconds Behind Master.

Several factors impact RabbitMQs responsiveness, including hardware specifications, network speed, available memory, and queue configurations. RabbitMQ ensures fast message delivery when queues are not overloaded.
Measuring Performance With Server Timing. Measuring Performance With Server Timing. That issue is slow server response times. There’s very little browser optimisations can do to improve a page that is simply slow to build on the server. Encompassed in that wait time is everything the server needs to do to build the page.
While most of our cloud & platform partners have their own dependency analysis tooling, most of them focus on basic dependency detection based on network connection analysis between hosts. What is the network traffic going to be between services we migrate and those that have to stay in the current data center?
When this happens, usually a k8s cloud-controller provided by the cloud vendor will detect that the actual server, in our case an EC2 Instance, has actually gone away, and will in turn delete the k8s node object. The annotations help document what happened to the node & pod: A real pod lost on a real k8s node that had a real kernel panic!
