The ASA 5500-X IPS SSP and Memory Usage
For the ASA 5500-X IPS SSP, the memory usage is 93%. The default health thresholds for the sensor
are 80% for yellow and 91% for red, so the sensor health will be shown as red on these platforms even
for normal operating conditions. You can tune the threshold percentage for memory usage so that it reads
more accurately for these platforms by configuring the memory-usage-policy option in the sensor health
metrics.
Note Make sure you have the memory-usage-policy option in the sensor health metrics enabled.
Table C-3 lists the yellow-threshold and the red-threshold health values.
Table C-3 ASA 5500-X IPS SSP Memory Usage Values
Platform Yellow Red Memory Used
ASA 5512-X IPS SSP 85% 91% 28%
ASA 5515-X IPS SSP 88% 92% 14%
ASA 5525-X IPS SSP 88% 92% 14%
