To determine the duration of a call in your Inbound Cagent, you can use the

dur_call_sec

metric provided by LiveKit's monitoring system. This metric tracks SIP call durations in seconds and is available for both inbound and outbound calls. Here’s how you can access it: • Use Prometheus to query the

dur_call_sec

metric. • Filter the metric by the

dir

label, setting it to

"in"

for inbound calls. • For example, you can use a query like: `dur_call_sec_bucket{dir="in", le="10"}`Adjust the

le

parameter to match the desired duration bucket. Let me know if you need further assistance with this! Sources: pkg/stats/monitor.go

Hey there! If you want to check out call metrics during an inbound call setup, here are a few ways you can do it: • Client-Side Metrics: LiveKit's SDKs (like Android and Swift) automatically gather important info like jitter, freeze counts, and packet details. These come through as

DataPacket

objects while the call is happening. • Server-Side Metrics: On the server side, these metrics arrive via data channels. You can set up listeners or hooks to grab and work with them. • Agent-Specific Metrics: You can subscribe to the

metrics_collected

event to keep track of metrics related to LLM, TTS, and STT data. The

UsageCollector

class is super handy for getting session summaries. • Custom Data Access: If you want the raw metrics during the call, you can add some logic to intercept and decode those

DataPacket

objects or use protobuf structures defined in LiveKit's protocol buffers. If you need even more metrics, you can always fetch them later using session or call IDs. Check out the LiveKit Metrics Documentation for some great examples and guidance. Feel free to reach out if you want a hand with any of these steps—I’m here to help!
