Does TR flow log incur charges?
TR flow log is currently free on the Transit Router (TR) side. A log generation fee may be introduced in the future. You will be notified of the billing timeline and details through in-site messages and product announcements. Feel free to use the service.
Since flow logs generated by TR are stored in Torch Log Service (TLS), corresponding service fees apply on the TLS side. For details, see TLS Billing overview.
Can I modify the log fields of a TR flow log?
When creating TR flow log, you can customize the log fields as needed. For details, see Flow log fields.
Once a TR flow log is created, the log fields cannot be modified. To change them, delete the flow log and create a new one.
Does TR flow log support fragmented packet statistics?
Yes.
Does modifying the collection cycle of TR flow log take effect immediately?
Yes. After the modification takes effect, TR stops ongoing log collection and immediately starts collecting and reporting logs based on the new collection cycle.
