What is Prometheus Alertmanager?

Alertmanager 0.34.2 turns off CORS by default, breaking cross-origin API calls.

Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.34.2 (October 29) stops sending CORS headers by default, so cross-origin calls to api/v2 now fail unless --web.cors.origin is set, and rebuilds with Go 1.26.10 to distrust the compromised eMudhra intermediates. 0.34.1 fixed inhibitions that could un-mute alerts, and 0.34.0 split auth and rate-limit failures out of the clientError metric reason.

What is Uptrends?

Uptrends spent October on account plumbing: vault credentials, bulk edits and a free trial path.

Uptrends is a synthetic and API monitoring service. October releases were mostly account and workflow items: credentials for authenticated monitors can now live in a shared vault instead of plain text, monitors can be bulk-edited with a preview of the credit impact, HTTPS and multi-step API monitors support the HTTP QUERY method, and free accounts can start a 30-day Enterprise trial. SCIM provisioning for Enterprise accounts arrived in late September, and e-invoices joined PDF billing.

Prometheus Alertmanager vs Uptrends: editorial side-by-side

P2.5

Alertmanager 0.34.2 turns off CORS by default, breaking cross-origin API calls.

◆ Current state

Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.34.2 (October 29) stops sending CORS headers by default, so cross-origin calls to api/v2 now fail unless --web.cors.origin is set, and rebuilds with Go 1.26.10 to distrust the compromised eMudhra intermediates. 0.34.1 fixed inhibitions that could un-mute alerts, and 0.34.0 split auth and rate-limit failures out of the clientError metric reason.

◆ Where it's heading

The 0.3x line keeps shipping breaking changes outside major versions: metric reason splits in 0.34.0, per-group markers in 0.33.0 and now a CORS default in a patch. Operators need to read every release note, not just minors.

◆ Prediction

Expect 0.35.0 to carry further breaking changes in the vein of 0.33 and 0.34, though the entries do not say what it will contain.

5.0

Uptrends spent October on account plumbing: vault credentials, bulk edits and a free trial path.

◆ Current state

Uptrends is a synthetic and API monitoring service. October releases were mostly account and workflow items: credentials for authenticated monitors can now live in a shared vault instead of plain text, monitors can be bulk-edited with a preview of the credit impact, HTTPS and multi-step API monitors support the HTTP QUERY method, and free accounts can start a 30-day Enterprise trial. SCIM provisioning for Enterprise accounts arrived in late September, and e-invoices joined PDF billing.

◆ Where it's heading

Two threads continue. Monitors are being made to behave like real API clients: after bearer tokens and JWT functions, HTTP QUERY lets a monitor send long search bodies without URL limits. The account side is being prepared for larger and more regulated customers: SCIM, vault-stored credentials and e-invoicing all serve procurement and IT rather than the person writing checks. The Enterprise trial for free accounts is the first entry here aimed at converting small users upward.

◆ Prediction

Existing monitors keep plain-text credentials until edited, so expect a migration prompt or bulk action to move them into the vault. Enterprise remains the tier that receives new capabilities first, as SCIM did.
