Antminer S1 monitor via snmp/syslog

[jimrome]

....... WHAT......?    enabling API may caused dead chips? Where you find this?

Complete bullshit until proven otherwise.

Not an unreasonable claim. I've gotten dead chips from simply rebooting. I've had to unplug the antminer and plug it back in to resolve them.

I disagree, and still call bullshit. Unless there is some other underlying issue (software corruption?) simply enabling the API shouldn't cause "dead chips".

Hi, API are active on Antminer S1, infact if you connect to console ad run the command cgminer-api summary there is an answer like this

<snip>

but is not allowed to call API from another computer else localhost (127.0.0.1) because in the configuration there aren't all necessary permission. So you need to enable the API for remote access. Someone suggest to edit /etc/config/cgminer. I do not know what solution is correct, but I think it is to edit /etc/init.d/cgminer because the etc/config/cgminer is written directly by Luci interface.

I think the 'correct' way would be to edit the /etc/config/cgminer config file - you'll see that /etc/config/init.d actually pulls values from it as well. Doesn't really matter I suppose as long as the values are properly passed onto cgminer upon launch.

is there any way to monitor a Antminer S1 via snmp/syslog.
im trying to get the temperature from the Unit.

Yes - I've just done this.

1) log into GUI and go to System --> Software --> [ Update lists ]   then wait a bit
2) Under Status, click the /Available Packages\ tab then click the /S\ tab
3) Scroll down to snmpd and click install.  You can ignore the snmpd-static and snmpd-utils packages.

4) SSH to your miner and log in as root
5) vi  /etc/snmp/snmpd.conf  and set it like this

rocommunity Waizphzbp3
exec minerstatus1 /bin/sh /root/cgminer-api-summary


6) vi /root/cgminer-api-summary    and set the contents like this

/usr/bin/cgminer-api stats      | egrep "temp|fan" | grep -v "Reply was"  | tr -d " []><()" | tr "=" ":"
/usr/bin/cgminer-api coin       | egrep "Time|Difficulty" | grep -v "Reply was"  | tr -d " []><()" | tr "=" ":"

7) Back to the web gui, go to System --> Startup  and "enable snmpd"   then click the start button for snmpd.

8) FAIL  This is the bit I haven't done yet.  My miner is not publicly accessible, so I simply disabled its firewall.
If you have an uncontrolled environment, you want to permit port 161 UDP from the monitoring host only.

9) To scan it I did this on my remote host.

snmpwalk -Os -c Waizphzbp3 -v 2c 192.168.1.93   .1.3.6.1.4.1.2021.8

which returns this output:

extIndex.1 = INTEGER: 1

To customise, simply edit the shell script in /root/cgminer-api-summary to suit your needs.
There are a heap of different options that  cgminer-api takes, the shell script simply formats them.
Some of the ones I've looks at:

/usr/bin/cgminer-api devs                      Info on attached asics
/usr/bin/cgminer-api pools                     Info on pools
/usr/bin/cgminer-api switchpool                Change to another configured pool
/usr/bin/cgminer-api notify                    unsure
/usr/bin/cgminer-api devdetails                device info, more details
/usr/bin/cgminer-api stats
/usr/bin/cgminer-api summary
/usr/bin/cgminer-api config         failover info
/usr/bin/cgminer-api coin           stats about current block and difficulty
/usr/bin/cgminer-api usbstats               Lots of stuff
/usr/bin/cgminer-api zero           reset counters ?
/usr/bin/cgminer-api hotplug                ?
/usr/bin/cgminer-api ascset         configure asics on the fly
/usr/bin/cgminer-api asccount               count attached asics
/usr/bin/cgminer-api lockstats              dunno - not compiled
/usr/bin/cgminer-api edevs          devs but for devices that are enabled only
/usr/bin/cgminer-api estats         stats but for enabled devices only.
/usr/bin/cgminer-api lcd                    One liner?  Not compiled in


Any questions please ask, and if you have fiddled your firewall please let us know the clean tidy way to do that.

It does what you need.

Mine doesn't work I guess.  I just filled in the IP under GUI SYSTEM/SYSTEM/LOGGING. My log server never shows anything. Is there something else besides this you have to do?

[btcfade]

nevermind, adding api-listen worked.. thanks for all the great help..

[btcfade]

it's logging to 514 syslog .. i'm gonna have to wait for it to crash again to see if it says anything other than /usr/bin/cgminer-monitor..

anybody know what i'm saying?

how can i do this without downloading snmp? i mean i already got talking to the server, do i have to send it commands? can it just send updates to the syslog?

Well the commands given above will return you info on your miner when run at the command prompt.

The SNMP stuff is just one way of running those commands remotely.  You could easily use a command like
    ssh miner /usr/bin/cgminer-api stats
And get the info that way.

Good thing about SNMP is it already offers permissions and networking framework.  I poll from Cacti which likes SNMP.
