11.3 Healthevents Queries
Healthevents queries, whether done from the CLI or through SNMP, output the same event strings
and syntax for active events. This section explains the various types of output that are retrieved
from healthevents queries. For more information on using the healthevents dataitem, refer to
Section 8.0, “Command Line Interface (CLI) Syntax and Arguments” on page 57.
11.3.1 HealthEvents Queries for Individual Sensors
Executing a healthevents query on a particular sensor target returns all active healthevents for that
sensor target in a concatenated string. One sensor may have multiple events. For example, running
the following healthevents query on the CMM BIST sensor:
cmmget -l cmm -t BIST -d healthevents
might return multiple events that are active on the BIST sensor in a concatenated string like this:
Mon Feb 2 19:51:05 2004
Major Event : BIST RTC Not Working
Mon Feb 2 19:51:09 2004
Major Event : BIST Both Ethernet interfaces are not working.
11.3.2 HealthEvents Queries for All Sensors on a Location
Executing a healthevents query on the “cmm” location in the CLI without a target specified
(cmmget -l cmm -d healthevents) returns all the healthevents for all CMM sensors in a concatenated
string. This includes all BIST, LAN, Telco Alarm, Voltage, and Temp sensors on the CMM. This
ability to retrieve all healthevents on a location also applies to the chassis, bladeN, FantrayN and
powersupplyN* locations.
* - PowersupplyN healthevents are dependent on the presence of IPMI-compliant power supplies.
The “pwr supply N” target on the chassis location is used for querying non-IPMI capabilities of
power supplies (i.e., Failure Detected). Querying the healthevents on the chassis location will
return all active events for all “pwr supply N” targets.
The CMM’s SNMP interface provides a “cmm” target that can be found in the listtargets ouput.
This target is used to execute healthevents queries for all active events on the CMM. Since each
OID in the MIB requires a target on the location, the “cmm” target was implemented in SNMP to
give the user the ability to do a healthevents query of the cmm location equivalent to the CLI
command “cmmget -l cmm -d healthevents”. Similar SNMP-specific targets also exist for chassis
and bladeN that allow users to retrieve all active events for that location. Refer to Section 19.0,
“SNMP” on page 97 for more information on SNMP.
11.3.3 No Active Events
When a healthevents query is executed in the CLI on a target that doesn’t have active events a
string will be returned that is a single line string with no timestamp or severity. Only this string will
be returned and won’t be concatenated with any other strings. For example, doing a healthevents
query from the CLI of a location or target that doesn’t have any active healthevents will return the
following string:
“[Target] has no problems.” - i.e., “chassis has no problems” or “temp snsr 1 has no problems”
