After loading this file into the tool, a series of health checks will be performed and depending on the results, the most adequate recommendations will be shown.

Running the Analysis
After excuting the tool, use the “browse” button on the top left corner of the application screen and select the file “perflog.txt”. The file is located at <EM_HOME>/logs/perflog.txt .
After selecting the file, it’s path will show up in the selection field.
Press the button “Start Analysis”. The checks will be performed and the results will be shown right away.
Interpreting the results
Sections of Data
The perflog.txt file collects a a variety of performance metrics from the Enterprise Manager after each 15 seconds cycle. For each cycle a line is added in the file with the current state of the reported metrics. The Perflog Analyzer tool reads all of these entries and groups it in sections.
Each section represents a load of data since an specific start fo the Enterprise Manager, where the last section represents the data since the last start registered in the perflog.txt file. All data previous to the first starts is not considered for the analysis.
e.g.: Let’s say an hypothetical perflog.txt file is being analyzed by the tool and contains data from 01/01/2014 up to 31/12/2014. If said file had 3 different starts registered on the dates :
The tool will analyze the data in file separated in 3 different sections being the following:
- Section 1 – data between 01/02/2014 – 05/06/2014
- Section 2 – data between 05/06/2014 – 20/11/2014
- Section 3 – data between 20/11/2014 – Last entry in the file.
Remark: All data befor the first start(01/01/2014 - 01/02/2014) will not be considered for analysis.
After running the analysis, the tool will enable a dropbox on the top of the application screen. This dropbox can be used to select the section of data on which the checks will be performed. By standard, the tool will show the most recent group of data.
Important: If you change the selected section, the check results may change as the entries being analyzed are specifically referent to the selected section period.
After running the analysis, the tool will organize the collected data and display it in 3 different tabs according to the selected section(see Interpreting the results – Sections of Data) :
- Results tab
- Checks tab
- Perf Log tab
The Results tab is the main tab, selected by standard. Right after the analysis it’ll bring the results for all the checks performed in the collected data for the selected section (see Interpreting the results – Sections of Data).
Each check is shown separately and brings a color alert representing the status of the results where:
- GREEN = OK – This check has found no problems
- YELLOW = Warning – This check has found some indications that require some attention
- RED = Problem – This check has found a sitution that requires some action
Along with the color alert, the check result will bring a short message indicating the check status and a textbox with the recommendations according to the results. At right side of each check, there is also a “See details” button which will bring you to this specific check under the “Checks” tab, where more information can be found about the results and the data analyzed.
The Checks tab is the second tab. Differently from the “Results” tab, it’ll show only one check results at time, but in more details. Depending on the check, this tab will bring the frequency with which some situations are present in the log as well as average values. In this tab, again, the results will be referent to the data for the selected section (see Interpreting the results – Sections of Data).
This tab is divided in two views:
- Left view – List of checks: This view shows the list of all checks performed by the tool. It is possible to directly select the desired check in the list to see it’s results.
- Right view – Check results: This view shows the the detailed results for the selected check. Differently from the results in the “Results” tab, this one will bring also more informative data about the check and the entries analyzed from the log file.
Perf Log Tab
The Perf Log tab is the third tab. This is an informative tab which collects and show the perflog analyzed entries, organized in a table. In this tab, again, the data will be referent to the selected section (see Interpreting the results – Sections of Data).
On the biggest area of this tab, the selected section’s entries are shown in an organized table. It is possible to sort the entries by any of the presented values.
Under the table, there is a small section of the application screen reserved for log messages regarding the tool execution.
