Route a Grafana alert to a read-only Mastra triage agent

Fri, 24 Jul 2026 00:00:00 +0000

When a Grafana alert fires, a Mastra agent reads the metric, pulls the failing trace, follows the stack to the bug at orders.js:23, and posts a cited file-or-close recommendation to Slack. Then it stops. It changes nothing, and a human makes the call. This is the first step of an SRE agent I’m building, read-only to start. The post walks through the whole loop and what I learned wiring it up. The code is public, so you can clone it and build it yourself .

How to correlate Mastra metrics, logs, and traces in Grafana

Thu, 16 Jul 2026 00:00:00 +0000

I had a Mastra agent whose Grafana error tile held at 0% while a tool inside it failed on every call. The metric wasn’t lying: the agent caught each thrown exception and answered anyway, so at the agent level nothing had failed. The tool had failed, and the logs showed it; the number everyone watches never did.

A Grafana dashboard for your Mastra agent metrics

Fri, 10 Jul 2026 00:00:00 +0000

A single Grafana dashboard is enough to watch a Mastra agent during an incident: five golden-signal numbers, a p95 latency, and the throughput and spend underneath. Because the exporter emits Prometheus histogram buckets, the p95 is a true windowed percentile, and every spike is tagged with its trace_id as an exemplar. This post builds that board, panel by panel, and ships the provisioned JSON so you can drop it into your own Grafana.

How to export Mastra agent metrics to Prometheus (no database required)

Fri, 03 Jul 2026 00:00:00 +0000

Mastra derives per-agent metrics (latency, tokens, cost) from its traces, and shows them well in Studio. When you want those metrics in Prometheus so your production monitoring and alerting can use them, you need a scrape endpoint that Mastra doesn’t ship. You can add one without running an analytics database. Mastra puts every derived metric onto an observability event bus, so a small exporter can listen, feed prom-client, and serve /metrics from memory, with no analytics database (DuckDB or ClickHouse) to run. Here is how I wired it up, and the open-source exporter that does it.
