Available metrics
Create a Signal
1
Open the Signals view
In the Trident dashboard, navigate to Signals in the left sidebar and click New Signal.
2
Select the metric and scope
Choose the metric you want to monitor from the dropdown. Then set the scope: either All agents in the project or a specific agent by name. Scoping to a single agent is useful when different agents have very different baseline characteristics.
3
Set the threshold condition
Define the condition that should trigger the alert. For example:
error_rate > 5%over a15-minutewindowlatency_p95 > 2000msover a5-minutewindowllm_cost > $10over a1-hourwindownew_findings >= 1with severity filterCritical
4
Configure the alert destination
Choose where Trident should send the alert when the Signal fires:
- Slack — select a channel (requires the Slack integration)
- PagerDuty — creates an incident (requires the PagerDuty integration)
- Email — sends to one or more addresses on the project
5
Save the Signal
Click Save. The Signal becomes active immediately and begins evaluating on the next metric interval. Its initial state is Active.
Signal states
Trident sends a resolution notification automatically when a Firing Signal returns to the Active state, so your team knows the issue has cleared without manually checking the dashboard.
Mute a Signal
During planned deployments or maintenance windows, you can suppress a Signal temporarily without deleting it:- Open the Signal from the Signals list
- Click Mute and select a duration: 1 hour, 8 hours, or 24 hours
