System Monitoring

Hardware needs to be one of the following Dell Poweredge models:

The following checks will be monitored via Dell OpenManage Server Administrator’s (OMSA) SNMP interface:

Check Warning Critical Platforms supported
Fans N/A Any fan less than minimum failure threshold 350, 650, 750, 850, 1850, 2550, 2650, 2850, 2950 PV220
Memory Status “non-critical” as reported by OMSA Status other than “OK” as reported by OMSA 350, 650, 750, 850, 1850, 2550, 2650, 2850, 2950
Temp Greater than maximum warning thresholds or less than minimum warning thresholds in OMSA Greater than maximum failure thresholds or less than minimum failure thresholds in OMSA 350, 650, 750, 850, 1850, 2550, 2650, 2850, 2950, PV220
Voltage N/A Status other than “good” as reported by OMSA 350, 650, 750, 850, 1850, 2550, 2650, 2850, 2950

RAID array Status other than “ready” or “failed” as reported by OMSA Status “failed” as reported by OMSA 1850, 2550, 2650, 2850, 2950, PV220*
Disks Status other than “disk online” as reported by OMSA Status “disk failed” or “redundancy lost” as reported by OMSA 1850, 2550, 2650, 2850, 2950, PV220*
Disk utilisation 80% full 90% full 350, 650, 750, 850, 1850, 2550, 2650, 2850, 2950
CPU utilisation Linux: Load of 3
Windows: 95% utilisation
Linux: Load of 5
Windows: 97% utilisation
350, 650, 750, 850, 1850, 2550, 2650, 2850, 2950
IP Network Connectivity 25% packet loss or 500ms latency 75% packet loss or 1000ms latency All
HTTP availability Anything other than a 2xx or 3xx code returned 4xx or 5xx error codes or port 80 not available All
HTTP delay If request takes 10% and 100ms longer than last request If request takes 12% or 120ms longer than last request. Or if request takes longer than 1000ms in total. All
FTP availability N/A Anything returned other than FTP code 220 (server OK) All
SMTP availability N/A Anything returned other than SMTP code 220 (server OK) All
MySQL availability N/A Cannot get connected or logged in as specified user All
PostgreSQL availability N/A Cannot get connected or logged in as specified user Linux hosts only

 

 

*PV220 itself does not have OMSA capability and requires a Dell controlling head unit (e.g. 2850) in order to be monitored.

In order not to generate false positives, the monitoring system has to have 3 consecutive failure states to generate an alert.

Monitoring is only currently available under Sysadmin Support.
