It seems I have the graphing going after all! Will gather some data and report back! This is so great, JinTu! How about a bounty for cgminer stats implementation? Once I mine some BTC i will send you a donation!

Glad to hear you got it going, and looking forward to your sample graphs.

I'm certainly open to a bounty for implementing cgminer stats. It's been on my todo list ever since the 2.1.0 release supporting the JSON API, but it has been near impossible to find the time. A bounty would help goad me into actually doing it.

You sir, are my hero! Will donate in a couple of days after I've set up the system! This is going to be VERY useful.

Thanks mate,

Be sure to post some sample graphs when you get it up and running.

I have been contemplating water cooling for my 4RU 19" rack mounted miners as well. Noise is a big issue for me due to the WAF, so I have been looking at passive radiators like these. They take up a lot more room, but are totally silent. My current thought is to mount an array of these to the side of the 19" rack so it doesn't take up additional space.

Data from a non-working one. It shows "success, 0 items 0 rows". Won't show any cards when I go to add graphs.

I suspect the errors in the cacti.log are telling me, but I need a more verbose output...

I worked with dlasher via PM and we were able to resolve this for his setup (SNMP timeout). Please see the update to the first post (Troubleshooting) for additional details.
85  Bitcoin / Mining / Re: Monitoring AMD GPUs with SNMP in Linux on: February 27, 2012, 10:43:39 PM
dlasher i fixed mine the same way like you, but there is more nasty bug with DUAL GPU adapters. Fans there are -1.
So if you have 6 adapters with IDs 0 1 2 3 4 5 . 1 of them is DUAL GPU. Lets say last one.
0 1 2 3 4 are physical. ID 5 is the second GPU. ID 5 must be ignored for fan polling. For load, temp etc is fine.


I would love to see a dump of this (with gpu_snmp.pl fan) if you can provide it. Since my rig only has two dual GPUs, I don't really know what this would look like in a mixed system. My dual 6990's report back two fan set points per card even though there is really only one attached fan.

86  Bitcoin / Mining / Re: Monitoring AMD GPUs with SNMP in Linux on: February 27, 2012, 10:36:59 PM
Guessing it's this line in the script:

Quote
unless ($adapter_list =~ m/^.*\d+\.\s+\d{2}:\d{2}\.\d\s+.*/) {


Yep, you nailed it. The regex doesn't work with anything other than 0-9 at the moment. I'll post an updated version that should work with your setup as soon as I get a couple minutes free.

Thank you! You've created one of what I considered the missing pieces for miners with any decent GHash rate.. I've got a couple of miners actually working in Cacti, and once this is fixed, I'll can find the remaining issues and get the others going. Looking forward to the patch.

I played with a  little. The right fix would be matching to something like [0-9a-fA-F][0-9a-fA-F] but for now I was able to change d{2} to w{2} in both places it matches, and get by.

when i do that with my 6970, it defaults back to stock settings.

I think this is an issue with the 6xxx series, not the miner software.

All 6000 series cards are restricted to GPU clock -125 for memclock.  For example, if you are running at 900 on GPU, the lowest you can clock the memory is 775.  Anything lower than 125 below the GPU clock will reset the memclock to stock speed.
Windows applications have extra backdoors to the hardware to get around this. We have no cross platform->linux code that can do this, nor do I have access to how it's done on windows. So afterburner and others can work around this limitation.

It is possible to run 6000 series cards at significantly lower memclock rates on Linux, but you need to be willing to reflash your cards. I currently run my dual 6990 rig at a memclock of 150 with a GPU clock of 600 (higher is possible, but cooling/fan noise is an issue with the placement of my rig). The big upside to running at a lower memclock is reduced power consumption, but this would only work if you have a dedicated mining rig.

Sorry for cross-posting, but this would seem to be relevant to both the main cgminer and this API thread.

I hacked together a workalike version of api-example in Perl leveraging the JSON parlance of the API supported by Kano's wonderful enhancements.

Details are here.

Here is my quick and dirty Perl implementation of api-example. Just copy and save this as api-example.pl. Note, you need to have the JSON Perl module installed to use this (perl-JSON for RH-based distros).


Code:
#!/usr/bin/perl -w

}

# Now read the result
my $response = <$remote>;

print $command . " returned \'$response\'\n";

# Now parse the JSON
my $json = new JSON;

  else {
    # This is not an array so just print it
    print "\t" . $json_text->{$tlc} . "\n";

# make sure we close the socket
$remote->close();


This will give you output like the following:

Hi Con, It looks like api-example.c, api-example.php, API.java/API.class and miner.php didn't get packaged up in the 2.1.0 source tarball. I see they are there in GIT but the README implies they are included in the main distribution.

Is that with the new Xorg version (video ABI 11)? I've been having trouble with that as the fglrx driver causes a crash whenever I try to watch a video, so I downgraded Xorg and everything was fine once more.

Anyhow, your backtrace suggests that the crash has something to do with setting fan speed. Are you having cgminer manipulate that? If so, does the crash also happen when you start cgminer without --auto-fan or any other fan related options?

I'm using the latest stock version for CentOS 6: xorg-x11-server-Xorg-1.7.7-26.el6_0.3.x86_64. Grepping for ABI in my X logs I get the following:

Code:
(II) Module ABI versions:
        ABI class: X.Org Server Extension, version 2.0
        ABI class: X.Org Server Extension, version 2.0
        ABI class: X.Org Server Extension, version 2.0
        ABI class: X.Org Server Extension, version 2.0
        ABI class: X.Org Server Extension, version 2.0
        ABI class: X.Org Server Extension, version 2.0
        ABI class: X.Org Video Driver, version 6.0
        ABI class: X.Org Video Driver, version 6.0
        ABI class: X.Org ANSI C Emulation, version 0.4

Yes, I am indeed using --auto-fan. I tried omitting this option (first setting the fanspeed manually with aticonfig) and it still causes the same error when I instruct cgminer to quit and X crashes.

Hi folks,

I have been having a rather annoying issue with X crashing when I stop cgminer with 'q' about 80% of the time. When I quit and it doesn't crash X, the mining statistics text is truncated and cgminer doesn't fully exit until I hit Ctrl-C twice.

When it crashes, I see the following in my X logs:

Good news guys. I just tried upgrading to the ATI 11.11 driver on linux and the CPU usage bug is finally fixed, AND it works with newer xorg 1.11 (in case you're on a very recent distribution, like Archlinux).

How many GPUs?
1 GPU has been fixed since 11.9
2+ GPU was unfixed as of 11.10

If 2+ GPU work in 11.11 that is awesome.
Even 1 GPU was NOT fixed for many of us on either 11.9 or 11.10.

11.11 fixes CPU usage for any number of GPUS for me.

Confirmed in my CentOS 6 x86_64 dual 6990 rig as well. Loving the lower power consumption!

Looks awesome.. ! Ill have to try this later. Can you somhow include hashrate from some of the popular miners too?

This version of the script (and the reported stats) are totally independent of any mining software you might be using, so you can use any application that uses your GPUs (mining or otherwise)

I plan to do another script to scrape the stats cgminer provides for hashrate but am not sure when I will get around to it.
98  Bitcoin / Mining / Cacti template for AMD GPU monitoring on: October 18, 2011, 06:13:39 AM
By leveraging my earlier work exposing GPU stats via SNMP, I created a Cacti template for monitoring my mining rigs and would like to share my work with all of you.

Here are some teaser graphs from one of my (largely untuned) 6990 GPUs:

Adding graphs to Cacti


Core clock for GPU 0


Memory clock for GPU 0 (underclocked to 150MHz)


Core voltage for GPU 0


Fan speed for GPU 0


Temperature for GPU 0


Load for GPU 0



Prerequisites

Installation instructions
  • Grab the latest template package from here.
  • Unzip the package and copy snmp_queries/amd.gpu.xml to your snmp_queries directory i.e. /var/www/html/cacti/resource/snmp_queries
  • Import cacti_data_query_amd_gpu.xml from the Cacti web interface.
  • Add the 'AMD GPU' Data Query to your miner host or host template.
  • 'Create Graphs for this Host' as you would normally.

Troubleshooting
  • Ensure that the host's SNMP Timeout value is set adequately long (e.g. >5 seconds) as the polling cycle for a host can be quite long.

A Verbose Query should look like the following:
Code:
+ Running data query [16].

99  Bitcoin / Mining / Monitoring AMD GPUs with SNMP in Linux on: October 18, 2011, 12:22:51 AM
Hi folks,

I'm a big fan of monitoring system performance with SNMP and when it came to mining I didn't find much out there that satisfied my requirements, so I decided to put something together and share with you all. The following describes how to monitor a Linux-based host with any number of ATI GPUs:

Prerequesites
  • Linux host (makes use of aticonfig and POSIX signalling)
  • Perl
  • AMD drivers
  • All installed GPUs detected and operational
  • All GPUs must have support for PPLIB.
  • Net-snmp installed and operational


Installation instructions
  • Grab the latest script from here.
  • Install this script somewhere net-snmp can execute it (e.g. /usr/local/bin).
  • Edit the following lines in the script as appropriate for your environment:
Code:
########################################################
## Tweak the following variables for your environment
#
my $sudo = "sudo -u jintu";           # The sudo command to execute
my $aticonfig = "/usr/bin/aticonfig"; # The full path to aticonfig
my $display = "DISPLAY=:0";           # The display your X session and ATI GPUs are running under
#
  • Edit snmpd.conf (mine is in /etc/snmp) to include the following lines (edit the path as appropriate):
Code:
# These are multi-line output visible from NET-SNMP-EXTEND-MIB::nsExtendOutLine
extend  gputemp         /usr/local/bin/gpu_snmp.pl temp
extend  gpuload         /usr/local/bin/gpu_snmp.pl load
extend  gpuclock        /usr/local/bin/gpu_snmp.pl clock
extend  gpumemory       /usr/local/bin/gpu_snmp.pl memory
extend  gpuvcore        /usr/local/bin/gpu_snmp.pl vcore
extend  gpufan          /usr/local/bin/gpu_snmp.pl fan
extend  gpuid           /usr/local/bin/gpu_snmp.pl id
extend  gpuaddress      /usr/local/bin/gpu_snmp.pl address
extend  gpudescription  /usr/local/bin/gpu_snmp.pl description
#
  • Test with snmpwalk e.g. 'snmpwalk -v2c -cpublic localhost NET-SNMP-EXTEND-MIB::nsExtendOutLine' which should output something like the following from my dual 6990 rig:
Code:
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuid".1 = STRING: 0
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuid".2 = STRING: 1
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuid".3 = STRING: 2

NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpufan".1 = STRING: 85
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpufan".2 = STRING: 85
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpufan".3 = STRING: 85
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpufan".4 = STRING: 85
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuload".1 = STRING: 78

NET-SNMP-EXTEND-MIB::nsExtendOutLine."gputemp".3 = STRING: 7450
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gputemp".4 = STRING: 7550
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuclock".1 = STRING: 500
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuclock".2 = STRING: 500
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuclock".3 = STRING: 515
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuclock".4 = STRING: 505
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuvcore".1 = STRING: 1000
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuvcore".2 = STRING: 1000
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuvcore".3 = STRING: 1050
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuvcore".4 = STRING: 1050
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpumemory".1 = STRING: 150
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpumemory".2 = STRING: 150
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpumemory".3 = STRING: 150
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpumemory".4 = STRING: 150
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuaddress".1 = STRING: 03:00.0
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuaddress".2 = STRING: 04:00.0
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuaddress".3 = STRING: 07:00.0
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpuaddress".4 = STRING: 08:00.0
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpudescription".1 = STRING: AMD Radeon HD 6900 Series
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpudescription".2 = STRING: AMD Radeon HD 6900 Series
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpudescription".3 = STRING: AMD Radeon HD 6900 Series
NET-SNMP-EXTEND-MIB::nsExtendOutLine."gpudescription".4 = STRING: AMD Radeon HD 6900 Series



Troubleshooting
  • If you see "sudo: sorry, you must have a tty to run sudo" when executing the script via snmpd, comment out the following line in your sudoers file:
Code:
"Default requiretty"


    Wire up to your NMS as you see fit. For reference, I have posted my Cacti template utilizing these stats here.

    Have fun!

    And now all 3 pool servers are down.  I have a few weaker machines I'm bringing up that will proxy connections to our backend.  If they go down I'm out of options until the attackers stop.

    Looks like they hit Slush too.
