Example

# Display global OSPF statistics, including statistics of neighbors, processes, and instances.

<sysname> display ospf global-statistics brief

Neighbor cumulative data (OSPF total statistics):
  ----------------------------------------------------------
  Down:        0 Init:         0 Attempt:     0 2-Way:     0
  Exstart:     0 Exchange:     0 Loading:     0 Full:      3
  Instance Numer:            2  Process Number:            4
  HighSocketExpire:          0  HighSocketEmpty:      175719
  Total Neighbor Number:                   3
  Total Press:   LOW

**Table 1** Description of the **display ospf** **global-statistics** command output
Item	Description
Neighbor cumulative data (OSPF total statistics)	Neighbor statistics
Instance Number	Number of instances, including public network instances and VPN instances
Process Number	Number of OSPF processes running on the router
HighSocketExpire	Number of unprocessed messages in high-priority queues
HighSocketEmpty	Number of processed messages in high-priority queues
Total Neighbor Number	Total number of OSPF neighbors
Total Press	Total pressure of the current service In most cases, the Total Press field is LOW. If the number of retransmission timers or the number of LSAs being flooded in the OSPF processes exceeds a certain value (default 300), or the number of OSPF neighbors exceeds 300, the Total Press field is HIGH. If the number of retransmission timers and the number of LSAs being flooded in the OSPF processes fall below a certain value (default 300), and the number of OSPF neighbors falls below 300, the Total Press field is LOW.

# Display global statistics of OSPF process 1.

<sysname> display ospf global-statistics process 1

  OSPF 1 statistics data:
  -----------------------------------------
  LSA NUM of Flood cache:          0
  Packet NUM of FloodUpdt Hash:          0
  Packet NUM of Flood Queue:          0

**Table 2** Description of the **display ospf global-statistics process 1** command output
Item	Description
LSA NUM of Flood cache	Indicates the number of LSAs being flooded in the OSPF process
Packet NUM of FloodUpdt Hash	Indicates the number of Update packets waiting to be flooded in the OSPF process, and the number does not reach the MTU.
Packet NUM of Flood Queue	Indicates the number of Update packets waiting to be flooded in the OSPF process, and the number reaches the MTU.

# Display OSPF time wheel information.

<sysname> display ospf global-statistics timewheel

 =================== TimeWheel Info Begin ===================
 TimeWheel current index is 2845, datanode count is 8
 Bucket Number: 3596, Expiry time: 1306(s), Datanode Count: 0
 High expiry time: 0, Low expiry time 527742(s)
 Bucket Number: 3597, Expiry time: 1307(s), Datanode Count: 0
 High expiry time: 0, Low expiry time 527743(s)
 Bucket Number: 3598, Expiry time: 1308(s), Datanode Count: 0

**Table 3** Description of the **display ospf global-statistics timewheel** command output
Item	Description
TimeWheel current index	Indicates the current index of the time wheel.
datanode count	Indicates the total number of nodes in the time wheel.
Bucket Number	Indicates the total number of indexes of the time wheel.
Expiry time	Indicates the expiry time of the index.
High expiry time	Indicates the high expiry time corresponding to the index in the time wheel after the system starts.
Low expiry time	Indicates the low expiry time corresponding to the index in the time wheel after the system starts.
