Dynatrace

JUNE 25, 2020

Dynatrace Managed is intrinsically highly available as it stores three copies of all events, user sessions, and metrics across its cluster nodes. This means that Dynatrace continues full operation when a majority of nodes are up and a maximum of two nodes are down at a time. What’s next?

Fast, consistent application delivery creates a positive user experience that can ultimately drive customer loyalty and improve business metrics like conversion rate and user retention. DEM can give organizations business observability—insight into the effects of user experience on the bottom line. What is digital experience monitoring?

For example, teams can further segment the telemetry data captured from a mobile app based on operating system, device, region, app version, and other custom metrics, to provide more granular insights on users and their behavior. When it comes to mobile app development, it’s vital that owners get the full picture.

Making applications observable—relying on metrics, logs, and traces to understand what software is doing and how it’s performing—has become increasingly important as workloads are shifting to multicloud environments. We also introduced our demo app and explained how to define the metrics and traces it uses.

In-Memory Storage Engine, as the name suggests, stores data in memory for faster performance and lower latencies. Compaction operation defragments data files & indexes. However, keep in ming that it does not release space to the operating system. The compact process releases the free space to the operating system.

The primary metric for memory bandwidth in multicore processors is that maximum sustained performance when using many cores. This metric is interesting because we don’t always have the luxury of parallelizing every application we run, and our operating systems almost always process each call (e.g.,

But do you know how Lighthouse calculates performance metrics like First Contentful Paint (FCP), Total Blocking Time (TBT), and Cumulative Layout Shift (CLS)? Still, there’s nothing in there to tell us about the data Lighthouse is using to evaluate metrics. But it comes with caveats. So why use lab data at all?

With a few clicks in the AWS Management Console, customers can use Amazon EFS to create file systems that are accessible to EC2 instances and that support standard operating system APIs and file system semantics. Synchronous events operate with low latency so you can deliver dynamic, interactive experiences to your users.

This boils down to a single digit µs latency toleration in the tail for far memory, and in addition to security and privacy concerns, rules out remote memory solutions. Thus we’re fundamentally trading (de)-compression latency at access time for the ability to pack more data in memory.

Concurrency refers to the system’s ability to carry out multiple tasks in parallel and manage the access and usage of shared resources. A distributed system comprises of a variety of hardware and software components with different operating systems and technologies, meaning the processors are separate and independent of each other.

When running a single user thread, you will often get the advertised single-core Turbo frequency, but if the operating system enables more cores to handle (even very short-lived) background processes, your frequency may drop unexpectedly. RDTSCP can still be executed later than expected, but not earlier.

SQL Server According to Bob

JANUARY 11, 2020

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. SQL Server always checks I/O completion status for any operating system error conditions and proper data transfer size and then handles errors appropriately. The data transfer size is not valid.

Load averages are an industry-critical metric – my company spends millions auto-scaling cloud instances based on them and other metrics – but on Linux there's some mystery around them. But to understand them in more detail is difficult without the aid of other metrics. I've never seen an explanation.

Collecting some critical metrics at one second intervals, with a total observability latency of ten seconds or less matches the human attention span much better. For systems that are latency sensitive, creating two independent ways to succeed is an important technique for greatly reducing the 99th percentile latency.
