Metrics Monitor in 2015R3 Does Not Run

[John_H_7]

Hi,

I've installed the Media Server Professional 2015R3 on a CentOS 7 system. The install went well, and encode and decode samples are working fine.

Not so lucky with the Metrics Monitor.  When I either run the provided binary our build and run the sample, it immediately fails when CTTMetrics_Init(0 is called with:

ERROR: Failed to initialize metrics monitor, error code -10

Doc is no help; it list no error return possibilities.

Any suggestions on getting it going?

Thanks,

John

Hi John,

Can you provide more details on the system you are using? 

Just to clarify, you ran the ./build.sh script from the metrcis_monitor/sample folder, and then ran ./run.sh?

[John_H_7]

Hi,

Thanks for the reply.

The system is a Supero X10SLH-F.  It has 8 cores -  Intel(R) Xeon(R) CPU E3-1285 v3 @ 3.60GHz. It has 12GB of memory.

And yes, it builds fine with the script, but does not run when the script is executed.

Decode and encode samples run fine.

Regards,

John

Hi,

I'm still interested in getting the Metrics Monitor going.

Suggestions, please?

Hi John - Apologies for the delayed response. The metrics_monitor tool needs to be run as root (not sudo, but as root). Can you please ensure you are doing that, and get back to us? Thanks.

[John_H_7]

Nothing quite so obvious as running non-root:

[Sravanthi_K_Intel]

The error you are observing corresponds to -     CTT_ERR_DRIVER_NO_INSTRUMENTATION   = -10, /* i915 driver has no instrumentation */

(This is available in the <msdk install>/tools/metrics_monitor/include/cttmetrics.h )

This could be an issue with the stack or kernel or metrics_monitor issue itself. To understand more, could you please provide the following information? I could take a look at it and also escalate it. Provide the output of:

- uname -ar

- lmsod | grep i915

- what is the MSS version i use (the latest one on the web is the R4 version, hope you re using that).

Thanks.

[John_H_7]

Ok, here you are:

MSS version is from this last January -  MediaServerStudioProfessionalEvaluation2015R3 Perhaps there's a new release out now? Would that help?

Thanks.

John

[Sravanthi_K_Intel]

Thanks for the information. Will get back to you soon.

MSS version is from this last January -  MediaServerStudioProfessionalEvaluation2015R3 Perhaps there's a new release out now? Would that help? --> Yes, please update to the latest version available now (which is R4)

[Sravanthi_K_Intel]

Hi John - Can you verify the KMD driver installation? The metrics monitor requires instrumented KMD driver from the Media Server Studio package, and please make sure that driver is installed correctly (we package 2 install scripts and getting started guide, which goes over install instructions including KMD driver install).

[Sravanthi_K_Intel]

Smoke test to check if KMD driver w/instrumentation was installed from MSS correctly - if this file does not exist, then KMD from MSS needs to be installed again “/sys/kernel/debug/dri/0/i915_ringstats"

If this file above exists and you still get the error, please let us know. Thanks.

[John_H_7]

No, it's not there.

I'm going to upgrade to 2015R4 anyway, so let's see what happens then.  I presume this file should still be there when 2015R4 is installed?

[Sravanthi_K_Intel]

John - Yes, please update to R4 and you should find the instrumentation file in it. (Although there is no reason why it should not already be part of R3 - it is included. My guess being KMD driver from MSS was probably not installed correctly).

I have exactly the same problem and it is very embaransing not to have metrics on the Iris!

Would be very helpfull if somebody from Intel responds to this!

Hi gabriel and Stan,

There is the other thread is talking about this issue too, someone in Ubuntu changed the complier version go g++4.9 and fixed it temporarily before the reboot. This is like a software issue.

We have same problem, so i pass this problem and now using intel_gpu_top from intel-gpu-tolols package, it works!
