Chapter 14. Monitoring using qdstat

Create a state dump containing all statistics for all routers

A state dump shows the current operational state of the router network.

qdstat --all-routers --all-entities

$ qdstat --all-routers --all-entities

If you run this command on an interior router, it displays the statistics for all interior routers. If you run the command on an edge router, it displays the statistics for only that edge router.

Create a state dump containing a single statistic for all routers

qdstat -l|-a|-c|--autolinks|--linkroutes|-g|-m --all-routers

$ qdstat -l|-a|-c|--autolinks|--linkroutes|-g|-m --all-routers

If you run this command on an interior router, it displays the statistic for all interior routers. If you run the command on an edge router, it displays the statistic for only that edge router.

Create a state dump containing all statistics for a single router

qdstat --all-entities

$ qdstat --all-entities

This command shows the statistics for the local router only.
