Understanding Enhanced Analytics Local File Output
The network analytics feature provides visibility into the performance and behavior of the data center infrastructure. You enable network analytics by configuring queue or traffic statistics monitoring, or both. In addition, you can configure a local file for storing the traffic and queue statistics records.
 | Note: This topic describes the local file output in Junos OS Release 13.2X51-D15 and later. For information about local file output from earlier releases, see the monitor start (Analytics) topic. |
Beginning in Junos OS Release 13.2X51-D15, the traffic and queue monitoring statistics can be stored locally in a single file. The following example shows the output from the monitor start command.
