    Symptom

     

    Nagios “Memory-usage” shows “2 warnings and critical !” for CPU load and memory usage.

    Origin

     

    Nagios monitors systems, networks and infrastructure. It also provides monitoring and alerting services for servers, switches, applications and services. Ideally, it can use SNMP protocol to monitor FireEye appliances for system monitoring, but there a few snmp events it does not handle well - such as CPU load and memory usage.

     

     

    Solution

     

    No action required. To get a better understanding of why this memory warning is not an issue, please see Information Guide: Linux and Memory as disk cache.
