Top tips is a weekly column where we highlight what's trending in the tech world and list practical ways to explore these trends. This week, we're clearing out the one notification nobody wants to see: storage full. You’re about to capture the perfect moment and a message pops up: Storage full. The same sentiment applies to a fridge:Nobody means to overstuff it, but a little goes in every day at a faster rate than items come out, until a lemon ends up balanced on the edge of a shelf.

OpenTelemetry (OTel) is an open-source observability framework, hosted by the Cloud Native Computing Foundation (CNCF), that standardizes how your applications generate, collect, and export telemetry data such as traces, metrics, and logs. The instrumentation stays vendor-neutral, so you can instrument a service once, send its telemetry to the observability tool your team uses today, and point it at a different tool next year without touching application code.

Symfony 8.1.10 is a maintenance release, but it carries a security fix in the Mime component, and Mime reaches further than the Symfony apps you’d expect. If you generate email anywhere in a PHP stack, this one is worth a look.

Ask Olly to audit your alert coverage and it pulls the whole set through the API, works through it with a script, and hands back the gaps as a report you can send to the team. DataPrime and PromQL already answer the questions that fit a query language, and Olly has been answering those for a long time. The sandbox is for everything else: the sources that have no query language of their own, the correlations that span two languages at once, and the analysis that needs a script rather than a filter.

Why would a domain with correct records, healthy name servers and a valid certificate stop resolving for part of the internet? Often it's DNSSEC. Your records are fine; the signatures behind them are not, and any resolver that checks signatures now refuses to answer. DNSSEC was designed to stop spoofing and cache poisoning, and it works. The catch is operational.

Does your IT team have a clear view of your Cisco network's health and performance? Cisco routers, switches, firewalls, and wireless devices need regular monitoring to catch network issues before they affect users. Cisco network monitoring tools help you: However, not every tool supports Cisco technologies such as Meraki, IP SLA, ACI, and SD-WAN. In this guide, we compare 9 Cisco network monitoring tools based on their features, limitations, deployment options, and pricing.

Oracle AI World 2026 brought customers and partners to Las Vegas to explore how AI can support their existing business systems. At the event, Datadog participated in a session with Peloton Consulting Group and hosted a booth covering observability across Oracle Fusion Cloud Applications, Oracle Database, and Oracle Cloud Infrastructure (OCI).

For teams that own an application running on Kubernetes, updating its observability configuration should be as straightforward as updating any other Kubernetes resource. But configuring integration checks, log collection, and tracing often means working across multiple configuration paths. If those settings live in pod annotations, adding a metric check or changing log processing rules requires a Deployment rollout.

WooCommerce relies on a lot of work happening in the background. Some of that is handled by WordPress cron, while other tasks are queued through Action Scheduler. This can include things like sending scheduled emails, processing subscription renewals, delivering webhooks, running scheduled WooCommerce actions, and other maintenance tasks that do not happen during a normal page request. The problem is that when one of these background jobs stops running, it is not always obvious straight away.
