5## GPU Frequency
6
7GPU frequency can be included in the trace by adding the ftrace category.

9```
10data_sources: {
11    config {
12        name: "linux.ftrace"
13        ftrace_config {
14            ftrace_events: "power/gpu_frequency"
15        }
16    }
17}
18```

20## GPU Counters
21
22GPU counters can be configured by adding the data source to the trace config as follows:
23
24```
25data_sources: {
26    config {
27        name: "gpu.counters"
28        gpu_counter_config {
29          counter_period_ns: 1000000
30          counter_ids: 1
31          counter_ids: 3
32          counter_ids: 106
33          counter_ids: 107
34          counter_ids: 109
35        }
36    }
37}
38```
39
40The counter_ids correspond to the ones described in `GpuCounterSpec` in the data source descriptor.
