Recommended Configuration › Create SNMP Traps › SNMP Trap Severity Levels

SNMP Trap Severity Levels

Multi-Port Monitor SNMP traps are associated with key processes that detect error conditions that affect performance. Error conditions that correspond to the following severities trigger each trap:

• Info (least severe condition)
• Warning (medium-severity condition)
• Error (highest-severity condition)

You can select the minimum severity of traps that you want Multi-Port Monitor to send. Traps are then sent for any condition that meets or exceeds the criteria for the minimum severity. By default, all traps are enabled for a Warning or Error severity, but not for the Info severity.

The following SNMP traps are available:

mtpProcessTrap

This trap is sent when a Multi-Port Monitor process fails or is restarted. The trap text supplies the name of the process that was restarted. The trap is sent by default for the following conditions:

• Warning is sent when the watchdog process restarts another process.
• Error is sent when the watchdog process restarts the same process the maximum number of times.

mtpCaptureTrap

This trap is sent in response to an error or warning message from the network adapter (the capture card). Where applicable, the trap text supplies information to identify the affected adapter.

• Warning is sent when a physical port is no longer connected.
• Error is sent when the nqcapd process encounters a problem while capturing packets.

mtpDiskUsageTrap

This trap is sent when a disk usage threshold is exceeded for a file system.

• Warning is sent when disk usage reaches 80 percent.
• Error is sent when disk usage reaches 95 percent.

Tips:

• The mtpDiskUsageTrap monitors the /nqtmp/headers file system, a RAM disk file system. The /nqtmp/headers file system exceeds a threshold when the nqmetricd process is not sufficiently processing header files. Possible reasons include:
  • The nqmetricd process cannot query the CA Application Delivery Analysis management console for configuration information. Review the nqMetricReader.log file for indications of a SQL error.
  • The Multi-Port Monitor appliance can have resource issues that affect the nqmetricd process. Restart the appliance. If the problem persists or occurs again, contact CA Technical Support.
• The mtpDiskUsageTrap also monitors the /nqtmp/tim file system, a RAM disk file system. The /nqtmp/tim file system exceeds a threshold when the TIM process is not sufficiently processing packet files.

mtpRAIDTrap

This trap is sent in response to a RAID array or disk drive failure.

• Info is sent when a RAID array that was rebuilding returns to an Optimal state.
• Warning is sent when a disk RAID array is degraded because a disk drive is rebuilding.
• Error is sent when either a disk RAID array failure or a degraded disk RAID array due to a disk drive failure is detected.

Note: This trap is available only if the Adaptec Storage Manager (arcconf) utility is installed. For more information, see the CA ADA Multi-Port Monitor Installation Guide.
