+### Sub-collectors
+
+The DNS collector is split into two sub-collectors:
+
+1. `metrics` - Collects standard DNS performance metrics using PDH (Performance Data Helper)
+2. `wmi_stats` - Collects DNS error statistics from the MicrosoftDNS_Statistic WMI class
+
+By default, both sub-collectors are enabled. You can enable specific sub-collectors using the `collector.dns.enabled` flag.
+
+### Example Usage
+
+To enable only DNS error statistics collection:
+```powershell
+windows_exporter.exe --collector.dns.enabled=wmi_stats
+```
+
+To enable only standard DNS metrics:
+```powershell
+windows_exporter.exe --collector.dns.enabled=metrics
+```
+
+To enable both (default behavior):
+```powershell
+windows_exporter.exe --collector.dns.enabled=metrics,wmi_stats

W32Time initiates clock correction by using this offset and updates the computed time in between samples with the remaining time offset that needs to be applied to the local clock. Clock accuracy can be tracked by using this performance counter with a low polling interval (for example, 256 seconds or less) and looking for the counter value to be smaller than the desired clock accuracy limit. | gauge   | None       |

+| `windows_time_computed_time_offset_seconds`        | The absolute time offset between the system clock and the chosen time source, as computed by the W32Time service in microseconds. When a new valid sample is available, the computed time is updated with the time offset indicated by the sample. This time is the actual time offset of the local clock. W32Time initiates clock correction by using this offset and updates the computed time in between samples with the remaining time offset that needs to be applied to the local clock. Clock accuracy can be tracked by using this performance counter with a low polling interval (for example, 256 seconds or less) and looking for the counter value to be smaller than the desired clock accuracy limit. | gauge   | None       |
