High memory usage-bluecoat-sgos

Vendor: bluecoat

OS: sgos

Description:
Indeni will alert if the memory utilization of a device is above a high threshold. If the device has multiple memory elements, each will be inspected separately and alert for.

Remediation Steps:
Determine the cause for the high memory usage of the listed elements.

How does this work?
This script logs into the Bluecoat Proxy using SSH and retrieves the memory utilization from the “show resources” command.

Why is this important?
Monitoring memory usage is critical for evaluate the system’s health and make sure it’s not over utilized. High memory usage could lead to production impact in terms of dropped packets.

Without Indeni how would you find this?
It is possible to poll this data through SNMP.
