Introduction

  • RDK PROC ANALYZER is a tool that enables different teams like development, triage and testing to analyze the CPU and memory utilization of the processes that run on top of RDK framework.
  • It helps us in detecting the memory leaks, cpu and memory performance regressions.
  • This tool is implemented as a service.
  • Highly configurable (Parameters like period , time interval and processes to be monitored can be configured).

Code Flow

  • The main code flow of CPU Procanalyzer -

  • To get the Load Average information- 

  •  To get the Memory information- 

  • To get the Idle Percent Information-

How to Launch

This tool runs as a service.

If the file /tmp/PROC_ANALYZER_ENABLE is touched the tool starts running and it logs the details.

How to Configure:

1 Open  ‘/opt/rmfconfig.ini’ file on the device.

    Parameters that can be configured:

                   (a)Time Interval

                   (b)Period

                   (c)Enable Dynamic

(a) Time Interval : It is the amount of time the tool runs.

(b) Period        : It is the interval of time for which the tool records the information.

(c)Enable Dynamic : This is a flag to disable and enable the capturing of dynamic processes
                     ( Enable Dynamic = 1 means enable and Enable Dynamic =0 means disable ).

It would take the default values if not configured (sleepsecs:60, Time to run:0, Dynamic:1)


Ex: FEATURE.CPUPROCANALYZER. SLEEP.SECS=60

    FEATURE.CPUPROCANALYER.TIMETORUN.SECS = 0 (which means tool runs until it is killed manually)

    FEATURE.CPUPROCANALYZER.DYNAMIC = 1


2. Open ‘/opt/processes.list’ file on the device.

    If the output path could also be configurable that would be great

      Hi Vivek,

      Could you please provide more information on this query.?

      1. Vivek Arumugam

        Hi Ganesh,


        I see that as of now the path where the output files are written is hardcoded as /opt/logs/. But this tool can be used to monitor the health of the system for a longer periods as well, in that case, the default /opt/logs directory could run out of space. This is more true with client devices where the /opt space is small. Providing an optional arg as to where to store the output files would be more flexible.


        Also I observed few more issues on attempts to use this.

        1) there is no link or attachment for the visualizer. I had to get it from Unknown User (mounika_lingam) offline.

        2) there are empty files found in the resultant directory, which prevented from showing anything on the graphical part. I heard from mounika that the empty files may prevent anything from showing in the visualizer.

        3) there are duplicate process & thread entries in the drop downs in the visualizer, choosing most of them didn't show anything on the visualizer

        4) from the data I collected I didn't see the overall system cpu & memory usage graph, I only saw process wise graphs but that too as I mentioned in the previous comment were duplicates or didn't show anything on the graph

    Is the visualizer support available?
    I do not have access to RDKCOM-2098 ticket.

      Hi Unknown User (vineeth_shankar) currently visualizer support is not available
