About this plugin
MetrixWire APM traces every WordPress request end-to-end: response time, status, and (when SAVEQUERIES
is enabled) each $wpdb query as its own span. Detectors flag N+1 queries, slow endpoints, slow queries,
SELECT *, query floods and unhandled exceptions in the traces this plugin sends.
Setup is one button. Open MetrixWire → Connect and click Start monitoring: the plugin creates your
MetrixWire workspace, its project and its API key for you. No email address, no password, no URL to enter —
add an email and password later, under Account, whenever you want to sign in on the web too.
From then on everything lives in wp-admin:
- Dashboard — issue counts and their 7-day trend, a per-day chart, top issues, worst-affected routes, plan usage.
- Issues — every detection, filterable by severity, time range and route, with a detail view showing the sample request and each database query as a waterfall.
- Alerts — email or webhook rules for this site, with a test send.
- Settings — project name, collection toggles, API key rotation, SAVEQUERIES status.
- Account — set the account’s email and password, see its plan and this month’s trace usage, sign the site out.
A single Open MetrixWire button signs you into the full dashboard in a browser tab when you want it —
no password prompt, no second login.
Already have a MetrixWire account? Choose Sign in instead on the connect screen — the site attaches to
your existing account, and reuses its project if that site was connected before.
External services
This plugin is a client for MetrixWire, a hosted application performance monitoring service at
com (or your own instance, if you self-host it).
When you connect, the plugin sends this site’s URL and title and its WordPress and plugin versions, so
MetrixWire can create your workspace and its project. No personal data is sent at this point: the account
starts without an email address. If you later set one from the Account screen, or sign in to an account you
already have, that address and password are sent too — the password is verified remotely and is never
stored on this site.
While connected, each request sends the HTTP method, path, response status and duration, and — when
SAVEQUERIES is enabled — the SQL text and duration of each database query. The admin screens read this
site’s own monitoring data back from the same service. Nothing is sent before you connect, and nothing is
sent while the “Send traces from this site” toggle is off. Traces leave the site on the shutdown hook,
after the response has already reached the visitor.
