+### Understand the alert
+
+The Netdata Agent calculates the percentage of used memory. This alert indicates high cgroup memory utilization. Out Of Memory (OOM) killer will kill some processes when the utilization reaches 100%. To fix this issue, try to increase the cgroup memory limit (if set).
+
+This alert is triggered in warning state when the percentage of used memory is between 80-90% and in critical state between 90-98%.
