AgentPing vs Datadog for AI agents.

Datadog is the enterprise APM standard. AgentPing isn't trying to replace it; we're built for the layer Datadog wasn't designed for. APM watches infrastructure, requests, latency, and exceptions. AI agent observability watches the agent itself: what it costs, whether it's still running on schedule, whether the output is still good.

001 what datadog does well

Full-stack APM, custom metrics, deep enterprise tooling.

Datadog is one of the best general-purpose observability platforms in the world. Metrics, logs, distributed tracing, Synthetics, RUM, security signals, infrastructure mapping. If your team is already standardised on Datadog for everything, you can extend it to LLM calls with their LLM Observability add-on and custom metrics. The deeper your existing Datadog setup, the more value that path returns.

002 where agentping differs

Agent-aware out of the box. No glue code, no rate-card homework.

AgentPing is purpose-built around agents. The data model is the agent run, with rubrics, schedule freshness, and a rate card as first-class concepts. You don't write custom metrics for cost attribution, you don't hand-roll schedule alerts, and you don't maintain a rate card. The defaults exist; you override only when needed.

003 when to pick which

Complementary, not competing.

Most teams that run AgentPing also run Datadog. Datadog watches the systems; AgentPing watches the agents. If you can only afford one, Datadog is the broader tool, but the agent-specific questions (which agent cost what, did the cron fire, is the output still good) need an agent-aware tool, which isn't what Datadog is built for.

Pick Datadog if

You need full-stack APM with metrics, logs, traces, and security signals on one platform.
Your team is already deeply standardised on Datadog and adding a per-call LLM metric is an incremental change.
You're not yet running enough agents to justify a separate agent-aware tool.

Add AgentPing if

You ship AI agents to production and need cost attribution per agent / customer / feature.
You run scheduled agents and need missed-cron alerts within a grace window.
You want quality scoring on the live stream, not as a periodic eval.
You'd rather not maintain a rate card, a judge prompt harness, and a schedule-freshness scheduler yourself.

004 frequently asked

Datadog has LLM Observability now. Why not just use that?

Datadog's LLM Observability adds traces and token metrics on top of the existing APM. It's a fit when you already pay for Datadog and need a basic per-call view. It does not, by default, model agents as first-class entities, score output quality against a rubric, or page on a missed scheduled run. AgentPing is purpose-built around those three things.

Can I keep Datadog and add AgentPing for the agent-specific layer?

Yes, and that's a common shape. Datadog continues to monitor your infrastructure, request rates, web service latency, and exceptions. AgentPing adds the agent-aware layer: cost attribution per agent / customer / feature, schedule freshness on AI agents, and quality scoring on the production stream. The two have minimal overlap.

What about Datadog Synthetics for schedule monitoring?

Synthetics is built for HTTP endpoints. You can hack it into a heartbeat ping, but it doesn't carry the agent's context (last successful run, output, cost). AgentPing's schedule freshness is purpose-built: a cron expression plus a tolerance window per agent, with the alert payload including the prior successful run.

Can Datadog do cost attribution by agent and customer?

With effort. You'd emit custom metrics tagged by agent and customer, build a rate card model, write the pricing logic, and maintain it as providers change rates. AgentPing ships this out of the box with a server-side rate card and defaults for every Anthropic and OpenAI model AgentPing knows about. Cache-aware accounting is included.

How does pricing compare?

Datadog's pricing is per-host, per-metric, per-log volume. It scales up fast. AgentPing is flat-tier (£99 / £249 / £499 monthly) with predictable event allowances. For the agent-specific surface, AgentPing is materially cheaper at most volumes. For full-stack APM, Datadog remains the right choice.
