Health Events
Health Events 11
This section describes the health events that are associated with CMM events and includes the
syntax and severity of these strings. Refer to Section 10, “Sensor Types” on page 101 for more
information on the different type of sensors.
Note: For this section, “health event” (two words) refers to any event that is generated that reports the
health of a sensor. “healthevents” (one word) refers specifically to the “healthevents” dataitem or
the output of that dataitem (healthevents query).
11.1 Syntax of Health Event Strings
Health event string is a string that is associated with the particular health event occurring. Active
events are displayed in a healthevents query using the following command in the CLI:
cmmget -l [location] [-t [target]] -d healthevents
Active health events are also returned when healthevents queries are executed over SNMP. In
addition, all health events are logged in the SEL and sent out as SNMP Traps.
Note: SEL entries and SNMP traps do not include the severity of the event. Only healthevents query
results display the severity of an event.
11.1.1 Healthevents Query Event Syntax
The following is the syntax of a string returned by a healthevents query for an associated active
health event. The \n represents newline characters (seen as <0A> in SNMP queries).
[Timestamp]\n
[Severity] Event : [SDR Sensor Name] [Health Event String]: [Event Type]\n
• Timestamp is in the format: [Day] [Month] [Date] [HH:MM:SS] [Year]. For example,
Thu Dec 11 22:20:03 2003
• Severity is either Minor, Major, or Critical.
• SDR Sensor Name is the name given to the sensor in the Sensor Data Record (SDR).
• Health Event Strings are listed in Section 11.4, “List of Possible Health Event Strings” on
page 108.
• Event Type is either “Assertion Event” or “Deassertion Event” stating whether it is an event
that is being asserted or one that is being deasserted. This is not applied to threshold-based
sensor events since the string already states event type.
11.1.2 SEL Event Syntax
The following is the syntax of each SEL entry for an associated health event. The \n represents
newline characters and the \t represents tab characters.
