About MetrixWire APM
From the official readme · v1.3.0Description
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,
SAVEQUERIESstatus. - 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
https://metrixwire.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.

Frequently asked questions
Do I need a MetrixWire account before installing?
No — and you don’t need to create one by hand either. One click on the connect screen sets everything up. The account has no email or password until you add them under Account, which you only need if you want to sign in on metrixwire.com directly or recover the account later. If you already have an account, use Sign in instead on the connect screen.
Where do I enter my MetrixWire URL?
Nowhere. The plugin uses the hosted service at metrixwire.com. If you run MetrixWire yourself, point the plugin at it with define( 'METRIXWIRE_ENDPOINT', 'https://your-instance.example.com' ); in wp-config.php.
Do I have to open the MetrixWire website at all?
No. Connecting, reading issues, changing settings, managing alert rules and checking plan usage all happen in wp-admin. The Open MetrixWire button is there when you want the full dashboard, and signs you in automatically. Changing your paid plan is the one thing that leaves WordPress, because checkout is handled by the payment provider.
Can I configure this via wp-config.php instead?
Yes. Define METRIXWIRE_KEY, METRIXWIRE_ENDPOINT, and optionally METRIXWIRE_ENABLED as constants in wp-config.php — they take precedence over the saved settings, and the fields they cover are shown read-only. A site configured this way traces without connecting, though the in-dashboard screens still need a connection, since reading data back takes its own credential.
Why aren’t database query spans showing up?
SAVEQUERIES must be defined as a constant in wp-config.php; WordPress reads it before any plugin loads, so it can’t be turned on from a settings screen at runtime.
Does this slow down my site?
Traces are sent on the shutdown hook, after the response has already been sent to the visitor, over a short-timeout non-blocking request. Failures to reach MetrixWire are swallowed silently. The admin screens cache what they read for a minute, so browsing them doesn’t hammer the service either.
Who can see the data?
Anyone who can administer this WordPress site — the screens require the manage_options capability, and the Open MetrixWire button signs that administrator into the connected account.
Does it work on multisite?
Yes. Each site connects separately, keeping its own project and credentials, and uninstalling removes those from every site in the network.
What happens if I sign the site out?
The site stops tracing and its credentials are removed. Your MetrixWire project and its history are kept, so signing back in later picks that project up instead of starting a new one.
Changelog
Settings moved to a new top-level MetrixWire menu, which now shows your monitoring data directly in wp-admin. Existing API keys keep working; one click on MetrixWire → Connect unlocks the new screens.
1.3.0
- New “Critical” severity for requests that are broken — exceptions, 5xx responses and failing
external APIs — shown above High on the dashboard, in the issue list filter and the daily chart. - Alert rules can be limited to critical issues only; “High only” is now “High and up”.
1.2.1
- The bundled SDK now defaults to https://metrixwire.com instead of a local address, so a site
configured throughwp-config.phpconstants alone no longer posts its traces where nothing is
listening. Sites that setMETRIXWIRE_ENDPOINTthemselves are unaffected.
1.2.0
- Setup is now a single button: the account, project and API key are created with nothing to type — no
email, no password, no URL — and no visit to metrixwire.com. - Added an Account screen for setting the account’s email and password afterwards, and for signing the
site out. - New top-level MetrixWire menu with Dashboard, Issues, Alerts, Settings and Account screens — issue
lists, detail views with a query waterfall, alert rules and plan usage, all inside WordPress. - Added an “Open MetrixWire” button that signs the administrator into the dashboard with a one-time,
60-second ticket. - The service URL field is gone; the hosted service is assumed, and self-hosted installs set
METRIXWIRE_ENDPOINT inwp-config.php. - The API key is issued automatically, shown masked, and can be rotated from Settings.
- Added Sign out, which revokes this site’s credentials while keeping the project and its history.
1.1.0
- Renamed the plugin slug and text domain to
metrixwire-apm, with translation-ready strings and a
bundled.pottemplate. - Settings screen rebuilt on the WordPress Settings API, with a “Settings” shortcut on the Plugins row.
- wp-config.php constants now render as read-only values per field instead of disabling the form, so
saving no longer clears the options they cover. - Options are prefixed
metrixwire_apm_*; activation migrates values saved by the 1.0 plugin. - Uninstall now clears options on every site of a multisite network.
- Traces are posted with
wp_remote_post()instead of cURL, so the site’s HTTP transport, proxy
settings and filters apply.
1.0.0
- Initial release: settings screen, wp-config.php constant override, test-connection check, automatic
request + database query tracing.
