7.6.1 Collecting server monitoring history
This subsection explains the information that can be collected as server monitoring history and how to collect server monitoring history.
When HA Monitor collects server monitoring history, it records server slowdowns in the monitoring history file regardless of whether a failure has occurred. If the length of time during which no operation report is received from the server does not exceed the server failure monitoring time but does exceed a threshold value set by the user (time when server monitoring history is to be obtained), HA Monitor records a server slowdown in the monitoring history file.
The user must specify the following operands in the definition files beforehand:
-
ph_log_size operand in the HA Monitor environment settings
Specifies a size for a monitoring history file. For details about how to estimate and specify the size of a monitoring history file, see 8.3.1 HA Monitor environment settings (sysdef).
-
ph_threshold operand in the server environment definition
Specifies the time when server monitoring history is to be obtained.
