How the SMART Plug-In for WebLogic Server Works
Templates
The SPI for WebLogic Server template group contains three subgroups with
templates corresponding to WebLogic Server versions:
" WebLogic Server 6.0
" WebLogic Server 6.1
" WebLogic Server 5.1 (minimal functionality, equivalent to the Gallery
SPI; included here for your convenience; contains a single metric that
monitors the availability of WebLogic Server).
The two full-featured groups, WebLogic Server 6.0 and 6.1, contain two
template subgroups for monitoring WebLogic Server-related metrics and logfiles
and another template for intercepting messages as follows:
" Metrics: monitors incoming values that reflect WebLogic Server’s
performance levels and availability. Each value is evaluated according
to the metric with which it is associated. If it is acceptable, it is ignored;
if it is not, a message is sent to the OVO Message browser.
WLS Metrics contain monitor templates with settings for triggering
alerts/messages and collector templates, which show the metrics (each of
which has a unique number) whose values are collected for that interval.
Each collector template group is assigned a collection interval of
5 minutes, 15 minutes, one hour,orone day. The collection interval
indicates how often data is collected for that specific group.
Each monitor template determines the threshold conditions for the
monitored metric, the message text that is triggered when the threshold is
exceeded, the actions to execute, and instructions that appear.
Each collector template controls what metrics are collected. Specifically,
the collector template has three functions: (1) to run the collector/analyzer
at each collection interval and (2) to show all monitor templates within the
group, and (3) to specify which metrics are collected.
