Install Jentic One Beta

Connect the Cloud Logging API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Cloud Logging API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Cloud Logging API.

Write structured log entries with severity, resource labels, and trace correlation via entries:write

Query historical log entries across projects and folders with advanced filters via entries:list

Tail live log streams in real time for incident response via entries:tail

For Agents

Write log entries from agent runs, query historical logs with advanced filters, and configure sinks that export logs to BigQuery, Pub/Sub, or Cloud Storage for downstream analysis.

Use for: Write a structured log entry from my agent run with trace and severity, Search for ERROR-level log entries from the last hour in my project, Tail live logs for a Cloud Run service while I reproduce a bug, Create a log-based metric that counts authentication failures

Not supported: Does not handle metric storage, distributed traces, or alert policy management - use for log entry write, query, routing, and retention only.

Use Cases

Patterns agents use Cloud Logging API for, with concrete tasks.

★ Centralised application logging

Write structured log entries from application code, Cloud Run services, GKE workloads, and Compute Engine VMs into a single Cloud Logging project so engineers can search across the entire stack from one console. Severity, resource labels, and trace IDs make it possible to correlate a request as it flows through multiple services. Setup is typically under a day for a single project.

Call entries:write with a structured payload containing severity ERROR, jsonPayload with the exception details, and the trace ID extracted from the incoming request

Log-based metrics and alerting

Convert log content into Cloud Monitoring time series by defining log-based metrics that count matching entries or extract numeric values. Pair these metrics with alerting policies in Cloud Monitoring to page on-call when authentication failures spike or specific error patterns appear. Useful when you need observability signals that only exist in log content.

Create a log-based counter metric named auth_failures with a filter selecting severity=ERROR and jsonPayload.event=login_failed scoped to the auth service

Compliance log retention and routing

Use log buckets, views, and sinks to route audit and security logs into long-term storage in BigQuery for analysis or Cloud Storage for archive while keeping operational logs at shorter retention. CMEK settings allow regulated workloads to encrypt log data with customer-managed keys. Typical compliance-grade configuration takes 1-2 days including IAM scoping.

Create a sink named audit-archive routing logName matching cloudaudit.googleapis.com to a Cloud Storage bucket with 7-year retention

Agent integration via Jentic

AI agents that orchestrate Google Cloud workflows often need to record execution context, query past runs for context, or watch logs while executing remediation steps. Through Jentic the agent can write entries, list past entries by filter, or tail a live stream without holding the underlying OAuth token in its prompt.

Call entries:list with filter resource.type=cloud_run_revision AND severity>=WARNING for the last 30 minutes and summarise the top 3 error patterns

Key Endpoints

47 endpoints — cloud logging is google cloud's centralised log management service for writing, storing, searching, and routing log entries from applications, virtual machines, containers, and google cloud services.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your Google OAuth credential is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'write a log entry' or 'query GCP logs', and Jentic returns the matching Cloud Logging operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Cloud Logging API through Jentic.

What authentication does the Cloud Logging API use?

Cloud Logging uses Google OAuth 2.0 with scopes including https://www.googleapis.com/auth/logging.write for writing entries and https://www.googleapis.com/auth/logging.read for queries. Through Jentic the OAuth token is held in the encrypted vault and the agent receives only a scoped session, so the raw refresh token never enters the agent's context.

Can I tail live log entries through the Cloud Logging API?

Yes, the entries:tail endpoint streams log entries in real time as they arrive, which is useful for following a deployment or reproducing a bug. It accepts the same filter language as entries:list, so you can scope the stream to a specific service or severity.

What are the rate limits for the Cloud Logging API?

Read requests (entries:list, entries:tail) and write requests (entries:write) have separate per-project quotas published in Google Cloud's Logging quotas documentation, typically several hundred to a few thousand requests per minute. Enable batched writes and exponential backoff on 429 responses to stay under the limits.

How do I write a structured log entry through Jentic?

Search Jentic for write a log entry to cloud logging, load the entries:write operation, and execute it with a payload containing logName, resource, severity, and jsonPayload. Jentic handles the OAuth bearer token automatically so the agent only constructs the entry body.

Is the Cloud Logging API free?

Cloud Logging includes 50 GiB of free log ingestion per project per month, with usage above that billed per GiB. Querying logs via entries:list is free; long-term retention beyond the default 30 days incurs storage charges.

Can I export logs to BigQuery automatically?

Yes, create a sink with a BigQuery dataset destination and a filter expression. All matching entries are streamed into partitioned tables in the dataset, where you can query them with SQL alongside other Cloud data.

Can I limit what my agent is allowed to do with the Cloud Logging API?

Yes. Because you run Jentic One yourself, your own rules decide which Cloud Logging operations and which OAuth credential the agent may use. Since the log or resource name sits in the URL path (/v2/{+name}/...), you can pin the agent to a single log scope where it only writes and lists entries via entries:write and entries:list, and nothing else. Destructive or sensitive operations, such as copying entries out with entries:copy or changing CMEK encryption settings, stay excluded unless you explicitly allow them.
