Applicare Detector: Auto-Detecting Root Cause
The Applicare Detector looks at the WebLogic run-time
environment and detects issues. It then generates a report with the
abnormalities detected.
When Applicare monitoring is ON for a WebLogic Server,
Applicare automatically detects situations when WebLogic server is not able to
process incoming Application requests and it runs detector and blackbox
automatically. This helps find the abnormalities at the time when server is not
responding. Detector report will in most cases point to the root cause of the
hung WebLogic state.
Best of all, Applicare runs Detector automatically and
saves the results in the database when it detects adverse conditions. At the
same time detector can also be run at any particular time by WebLogic
Administrators to find out any issues with the runtime of WebLogic and
Application combination.
It is recommended to let Applicare monitor invoke the
Detector at the time when server is in hung state. This way you get an experts
analysis of the WebLogic State automatically. Detector uses the dynamic
knowledge database built by Arcturus engineers with years of WebLogic experience.
Since Detector looks at the runtime state of WebLogic server it is recommended
to run Detector on a Server that has been running for some time. If you run
Detector on a freshly started WebLogic server you may not get any results.
To run Detector:
- Select Applicare for WebLogic > Applicare Detector > Run Detector from the tree in the left pane.
- Select a server from the drop-down box that appears in
the right pane.
- Determine whether you want sensors to be automatically
created from the time that you run Detector. Click Toggle to
toggle Auto Sensors creation on and off, as indicated by the traffic light
icon. When Auto Sensors Creation is on, data relating to each
problem detected will be saved for analysis. You may want to turn Auto
Sensors Creation off if Detector finds many problems with the server,
since monitoring each one can consume a large amount of system resources.
- When you have decided whether or not to apply Auto
Sensors Creation to monitor the results, and have set the "Auto Sensors
Creation Toggle" button accordingly, click Start Applicare
Detector. Detector will then examine your WebLogic environment
for run-time problems. When the detection process is complete, a
message will display, notifying you that Detector has completed the
process.
To view Detector results:
- Click Applicare Detector > Show Detector
Results.
- Select the criteria pertaining to the areas you want to
examine using the drop down boxes. These drop down boxes include:
- Server
- MBean Type
- Name
- Time Period
- Date Range (Optional; used only when "Time
Period" is set to "Custom" Otherwise, this option is
disabled. See Step Three below.)
- If you want to specify a specific Date Range,
click the Custom Dates option from the Time Period drop-down. This allows you to click inside the From and To text boxes, displaying a calendar from which you can select the date
range by clicking dates directly on the calendar.
- When you have selected the criteria determining the
types of results you want to view, click "Apply". A
list of problems found by Detector will appear, detailing the following:
the Property, Value, Problem, and Date of each issue detected.
The example report below is
automatically generated by Applicare under slow database response condition
simulation. As you can see from the report Applicare is able to determine
connections pool utilization is maxed out, no database connections are
available and wait time is going up. Also we can see from the report that many
transactions are getting rolled back. This clearly tells us that database is
becoming the problem area.
