Syslog
Add Syslog to your product for your customers, and give your AI agents governed access to it.
Syslog is a protocol for moving log messages rather than a product, so there is nothing to sign up for: a customer supplies a host, a port, a transport and whatever credentials or certificate their listener requires, and messages flow. Each message carries a facility and a severity, which is what makes this operational rather than just file movement, because a message at critical severity is the alert, arriving as it is emitted instead of when something next polls. Two formats are in the wild, the older BSD-style layout and the structured RFC 5424 one, and past the header every vendor writes the body its own way, so parsing is configuration per customer. Repeats are normal too, since a flapping device emits the same line over and over, so identical messages are collapsed rather than turned into a queue of records.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Give each customer somewhere to enter their own listener host, port and transport, with whatever credentials it requires.
Forward the events your product generates into the collector a customer's operations team already watches.
Act on facility and severity when messages arrive, so a critical line raises something and a debug line does not.
Parse both the older BSD-style layout and RFC 5424 structured data per customer, because vendors format the body their own way.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads the recent messages for one customer's host and explains what changed before an outage.
An agent groups repeated messages so a flapping device reads as one problem rather than hundreds.
An agent emits a message to the customer's collector as part of a workflow, with the write logged.
Example prompt
Show the critical and error messages from this host in the last hour and tell me which repeated most.
Set up Syslog in 4 steps
- 01Enable the Syslog connector in your fastn dashboard.
- 02Have each customer supply their own host, port and transport, plus any credentials or certificate their listener requires.
- 03Map the facilities, severities and message formats your product handles, and decide how repeated messages are collapsed.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Syslog integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Syslog integration without building it. Your customers point it at their own endpoint and credentials and work their incidents, alerts and on-call schedules through it, with no per-customer code on your side.
- Handle the part that actually costs time: alerting is latency-critical and noisy, so filtering and deduplication matter. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Syslog update is not your on-call problem.
- One integration serves your product and your agents. The same governed Syslog connection powers in-product features and gives AI agents scoped, audited access, so you route operational signal to the people and systems that act on it without wiring it twice.

Azure Key VaultSyslog integration FAQ
How do I add a Syslog integration to my product?
Enable the Syslog connector in your fastn dashboard, then let each customer authenticate their own Syslog account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Syslog client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
How is a Syslog connection configured per customer?
Syslog is a specification rather than a service you sign up for, so there is no Syslog account. Each customer supplies their own endpoint and credentials, and that connection is scoped to them, so they only ever reach their own incidents, alerts and on-call schedules. The per-tenant isolation works the same way it does for a vendor product.
Can AI agents use this Syslog integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent reads the recent messages for one customer's host and explains what changed before an outage.
Who maintains the Syslog integration?
fastn does. When Syslog changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
How fast does a Syslog alert reach my product?
Alerts arrive through event triggers rather than polling, so your product reacts in near real time instead of on a schedule.
Can duplicate or flapping alerts be suppressed?
Yes. Events are deduplicated per incident, so a flapping check does not create a queue of identical records for your users to sift through.
What can I build with the Syslog integration?
A common starting point: give each customer somewhere to enter their own listener host, port and transport, with whatever credentials it requires. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Syslog integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Syslog does not change your per-connector cost. You can start free with 3 connected accounts.
