Diagnosing Switch Problems Monitoring Switch Health
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 34-39
Viewing Health Statistics for the Switch
The show health command can be used to display health statistics for the switch.
To display health statistics, enter the show health command, followed by the slot/port location.
For example, to view health statistics for the entire switch, enter the show health command without
specifying any additional parameters. A screen similar to the following example is displayed, as shown
below:
-> show health
* - current value exceeds threshold
Device 1 Min 1 Hr 1 Hr
Resources Limit Curr Avg Avg Max
-----------------+-------+------+------+-----+----
Receive 80 00 00 00 00
Transmit/Receive 80 00 00 00 00
Memory 80 87* 87 86 87
Cpu 80 08 05 04 08
Temperature Cmm 60 34 34 33 34
Temperature Cmm Cpu 60 28 28 27 28
In the screen sample shown above, the Device Resources field displays the device resources that are being
measured (for example, Receive displays statistics for traffic received by the switch; Transmit/Receive
displays statistics for traffic transmitted and received by the switch; Memory displays statistics for switch
memory; and CPU displays statistics for the switch CPU). The Limit field displays currently configured
device threshold levels as percentages of available bandwidth. The Curr field displays current bandwidth
usage for the specified device resource. 1 Min. Avg. refers to the average device bandwidth used over a 1
minute period. 1 Hr. Avg. refers to the average device bandwidth used over a 1 hour period, and 1 Hr.
Max. refers to the maximum device bandwidth used over a 1 hour period.
Note. If the Current value appears with an asterisk displayed next to it, the Current value exceeds the
Threshold limit. For example, if the Current value for Memory is displayed as 85* and the Threshold Limit
is displayed as 80, the asterisk indicates that the Current value has exceeded the Threshold Limit value.
