Failures live inside the response body \u2014 in the Send a specific query payload, then assert against the response body. Check whether the top-level Yes. Each monitor runs a defined query or mutation payload. Monitor your most critical mutations (placeOrder, processPayment) individually to track per-operation latency, error rate, and partial failure rate.<\/p>\n All common auth schemes: Bearer Token (the most common for GraphQL), OAuth 2.0 with automatic refresh, JWT, API Key, Basic Auth, AWS Signature v4, mTLS, and custom headers. Secrets are masked through Secure Vault. See auth matrix \u2192<\/a><\/p>\n Yes. Monitor the supergraph endpoint to verify the federation gateway is healthy, and monitor individual subgraph endpoints to isolate which service is failing when a federated query breaks. Works with Apollo Federation and similar architectures.<\/p>\n Total query latency is tracked, with P95\/P99 percentiles per query. To pinpoint individual slow resolvers, pair monitoring with your APM tracing \u2014 synthetic monitoring confirms the customer-facing slowness; APM confirms which resolver is the bottleneck.<\/p>\n Yes. Deploy Private Agents<\/a> inside your VPC or datacenter \u2014 common for backend-for-frontend (BFF) GraphQL services that aren’t publicly exposed.<\/p>\n Monitoring can include queries at various depths and complexity levels to verify your throttling and complexity limits are enforced. Pair with your WAF or query-complexity middleware for full protection.<\/p>\n GraphQL subscriptions typically use WebSocket \u2014 see our WebSocket monitoring<\/a> for connection establishment, message delivery, and keepalive checks.<\/p>\n Monitor the supergraph endpoint to verify the federation gateway is healthy AND monitor individual subgraph endpoints separately to isolate which downstream service fails when a federated query breaks. Both monitors share alerting routes for consolidated incident response.<\/p>\n GraphQL subscriptions use WebSocket transport. Use our WebSocket monitoring product to validate that the subscription connection establishes correctly, receives expected events, and stays alive across long-running sessions.<\/p>\n Yes. Configure persisted query identifiers (Apollo Persisted Queries or Relay-style hashes) in the request and Dotcom-Monitor will send them as the operation reference rather than the full query string.<\/p>\n Build monitors at increasing query depth and complexity to verify your complexity-limit middleware enforces the threshold correctly.

\n\t\t\t\t“One of Dotcom’s best features is the push\/pull API capabilities that provide us with network performance data. We use this to monitor for performance issues as well as page loading stats. Dotcom-Monitor allows us to monitor multiple services within one interface and platform. It’s allowed us to operate more efficiently.”Gregory S.Manager \u00b7 Broadcast MediaVerified Capterra review \u00b7 May 2020
\n\t\t\t\t“I have been thoroughly impressed with the level of detail and comprehensiveness of the reports generated by the software. Moreover, the support team at Dotcom-Monitor has exceeded my expectations. On almost a daily basis, I reach out with various questions and they have consistently demonstrated unwavering patience, providing detailed and insightful answers.”Shirin R.Software Test Engineer \u00b7 Computer SoftwareVerified Capterra review \u00b7 February 2023
\n\t\t\t\t“I’m a network analyst and use Dotcom tools inside the ISP I work, it’s a really good and reliable tool for monitoring things along the network, and testing network components, I usually use it to make diagnostics of servers latency, and dns resolve time.”Leonardo J.IT & Network Infrastructure Analyst InternetVerified Capterra review \u00b7 October 2022<\/p>\n
