Hardware Memory Module

PATROL Class: MS_HW_MEMORY - Monitor Type: MONITOR - Monitor Category: System
No CDM Class defined.

Monitors a specific memory module and verifies if it is present and operating correctly.

Attributes (Parameters)

Name PATROL Name Units Default Thresholds Description
Error Count ErrorCount errors None

Number of errors detected by the memory module and then corrected. A steadily growing value means that the memory module is not reliable and that it could encounter errors that it is unable to correct, which means this could lead to a system crash.

Value set by memoryColl.

Type: Statistics

Error Status ErrorStatus 0 = No Errors
1 = Detected Errors
2 = Too Many Errors

 WARN
if = 1 (Detected Errors)

 ALARM
if = 2 (Too Many Errors)

This parameter monitors the error status of the memory module based on the value of error count and the error thresholds set by the hardware agent.

Value set by memoryColl.

Type: Availability

Predicted Failure PredictedFailure 0 = OK
1 = Failure Predicted

 WARN
if = 1 (Failure Predicted)

A predicted failure is set by analyzing the trend of the number of detected/corrected errors (with the ECC technology). If predicted, replacement of the faulty memory module is highly recommended.

Value set by memoryColl.

Type: Availability

Present Present 0 = Missing
1 = Present

 ALARM
if = 0 (Missing)

Availability of the memory module.

Value set by memoryColl.

Type: Availability

Status Status 0 = OK
1 = Degraded
2 = Failed

 WARN
if = 1 (Degraded)

 ALARM
if = 2 (Failed)

Current status of the memory module. The Status parameter will raise an "on the fly" alert on servers that can dynamically handle failed memory modules or, most often, for modules that have been disabled by the BIOS upon reboot (the module is then flagged as missing).

Value set by memoryColl.

Type: Availability - Default graph

Status Information StatusInformation None None

Additional (textual) information about the current status of the memory module.

Value set by memoryColl.
