Disk I/O profiling with eBPF

Coroot's node-agent has had an eBPF CPU profiler for a long time. When something burns CPU, you open the flame graph and see which function. When something waits for the disk, you have nothing: the CPU profile is flat, because waiting does not consume CPU. The metrics for disk problems are always the same. Latency on a volume goes up, utilization hits 100%, queries slow down. Every chart agrees the disk is the bottleneck, none of them says what the database was doing while it waited. Flushing pages?

Run AURA in Slack without opening a single inbound port

Making an SRE agent available in Slack sounds straightforward until you start thinking about what that agent can access. If it's connected to Kubernetes, you need to consider how Slack communicates with the agent, what infrastructure the agent can inspect, and who can ask it to do something. Making operational tools easier to use shouldn't mean exposing another service or giving everyone unrestricted access to production.

Threat Advisory - Trojanized Claude Code Extension: SSH Backdoor

A tampered build of the Claude Code editor extension (anthropic.claude-code 2.1.313) was published on the Open VSX store used by Vs code,Cursor and similar editors, quietly gives attackers persistent remote access to any computer that runs it, while the extension keeps working normally. Researchers don’t yet know how it was published (the listing belongs to an Anthropic employee) or who is behind it. They found no evidence that Anthropic’s official Marketplace release was affected.

What Does a Network Administrator Do? Skills and Faster Fixes with Network Observability

When a branch office can’t reach the ERP system and customer calls start dropping, who gets the call? It’s almost always the network administrator. What that person does the rest of the week is less clear, and a CIO, a CFO and the admin themselves would probably each describe it differently. Part of the reason is how much the network has grown. Ten years ago it was mostly switches, cables and one building.

VoIP Monitoring: Metrics, Tools and How to Fix Poor Call Quality

With VoIP monitoring, you hear about a bad call before anyone opens a ticket. Voice handles trouble worse than most traffic on your network. When a file download drops packets, it just asks for them again. A live call has no time for that. A 2% burst of packet loss, which a download wouldn't notice, is enough for everyone on the call to hear a gap. Most of those problems start on the network path, which you can measure and fix.

Reading your ingestion history: hourly log counts, the partial hour and 7-day trends

The ingestion card on your Logit.io dashboard has a 24h / 7d toggle for Logs and Metrics, hourly log counts built from counter increases and a dotted line for the hour that is still filling in. Those three changes decide whether a dip on the chart is a real problem or just the clock.

AI-assisted log investigation on Logit.io today: Hosted OpenSearch MCP and onboarding AI prompts

On 8 October 2026 Elastic announced the private preview of Elastic nightshift AI SRE, an AI agent built into Elastic Observability that detects and investigates issues and shows its reasoning. It is a sign of where observability tooling is heading: more of the first hour of an incident handled by an assistant that reads your telemetry. Short answer: Logit.io does not offer an autonomous AI SRE agent.

Shopify outage on October 28, 2026: 504 gateway errors Shopify never acknowledged

Shopify merchants hit 504 Gateway Timeout errors on October 28, 2026, in a brief outage that Shopify never publicly acknowledged. For about 24 minutes, the Shopify admin and pages failed to load with “server not responding” and 504 errors for users across several countries. StatusGator detected the outage at 15:27 UTC, one minute after the first user report, even though it never appeared on Shopify’s status page.
