Hi Ankur,

Here are the steps that i would use,

- Run the command below to generate a text file containing space separated columns (time, total heap, used heap, requestor count),

$ grep 'Free memory' PegaRULES.log.2014-12-17 | awk '{print $1"-"$2, $22, $25, $28}' > temp.log

2. Open the newly created file from step above using Excel. Use space (‘ ‘) as a delimiter.

3. Insert a new row in the first row to include the title of each column. For example, time, total heap, used heap and requestor count.

4. In order to plot a chart, you can highlight all the columns and then try inserting a 2D line chart. A chart like below should be created,

5. In order to plot the requestor count on the second y-axis, double click on the requestor count line, and the following popup should appear.

6. Choose ‘Secondary Axis’ and click *Close*. You can now see the requestor count against the second y-axis.

Hope this helps.

Hi Waikei,

Have tried this yesterday, Really Awesome ! just in 2 minutes - able to generate the Memory Utilization over Requestor Count of our application. Thanks for sharing.

Thanks

Is there a Windows equivalent to this option? It looks like a great utility to have for any environment.

Thanks,

Hi Steve,

I used cygwin in Windows. But i quickly tried out the below and it seems to work.

for /f "tokens=1,2,22,25,28" %i in ('findstr "Free memory" <name of the PegaRULES.log>') do @echo %i-%j %k %l %m

Steve,

VisualVM and Cygwin are listed in the PDN Article, https://pdn.pega.com/node/1605, cited at the top of What are your favorite, free third-party tools?

Consider adding your new favorite freebies to the discussion, What are your favorite, free third-party tools?.

Thanks!

Salutations,

If you want a PR_PERF_STATS view of requestor counts along with a good view of a lot of important data, run this query... Easy to make pretty graphs and dig into the data... Second query gives you the details...
