Linux Host Availability Attributes

The Linux Host Availability attributes refer to Linux host availability characteristics. The attributes in this group can only be used in a situation. Historical information is available for the Host Availability table for users interested in trending server response times. However, to enable history collection for this attribute group, a list of monitored (pinged) servers must be specified. The list is specified through an environment variable - "KLZ_PINGHOSTLIST" in the lz.ini file in the Cloud Pak System Software Monitoring Server config directory. For example:

KLZ_PINGHOSTLIST='/opt/ibm/itm/config/klzpinghosts'

sample content of klzpinghosts:
#
# hosts pinged for availability from this agent
#
server1.domain.com
server2
server4

Host Status Result of the "ping" operation. The following values are valid: Successful (1), Unsuccessful (0), and Error (-1).

Server Response Time Ping operation response time in milliseconds. Note: -1000 indicates Not Available.

System Name The managed system name. The form should be hostname:agent_code.

Examples include spark:LZ or deux.raleigh.ibm.com:LZ.

In workspace queries, this attribute should be set equal to the value $NODE$ in order to populate the workspace with data. This attribute is generally not included in situations, unless there is a need to customize the situation for a specific managed system.

Target Host The host name or IP Address of the target of the ping operation. The following values are valid: alphanumeric text strings with a maximum length of 128 characters.

Time Stamp The date and time the agent collects information as set on the monitored system. The timestamp for SCAN and STR functions is displayed in the CYYMMDDHHMMSSmmm format (as in 1020315064501000 for 03/15/02 06:45:01) where:

C = Century (0 for 20th, 1 for 21st)

Y = Year

M = Month

D = Day

H = Hour

M = Minute

S = Second

m = millisecond
