cgmon - mining monitor for Linux - auto restart, reboot, sick gpu, ASIC, &more

[MrBobC]

So I have BAMT 1.3, and I seem to still be having problems with weird hashrates when cgmon starts sgminer.  Where can I change the command from the cgmon script starting the program to just running "mine restart" as root?  I think the script already runs as the root user.

[miner777]

Can someone please help me get cgmon working on BAMT?    I have the cgmon.tcl in the home folder. I have made all the changes to the cgmon.tcl file that I need to. I can manually run the cgmon.tcl file and it will work. However, for some reason the cron is not working. I am wondering if it has to do with the cron, or maybe it has to do with changing the file permission to 755. Maybe changing the permission is a different command in BAMT?  When I changed the permission of the file I used this command "chmod 755 cgmon.tcl".

I have not been sleeping good at night because I keep waking to check the rig. Would really like to get this script going.

[MrBobC]

That is the correct command.  In crontab you have the */2 * * * * root /home/user/cgmon.tcl >/dev/null 2>&1

[miner777]

That is the correct command.  In crontab you have the */2 * * * * root /home/user/cgmon.tcl >/dev/null 2>&1

MrBob, I sincerely appreciate the help.

Yes, I have the crontab setup and it looks like this:

*/2 * * * * root /home/cgmon.tcl >/dev/null 2>&1

My cgmon.tcl file is in the /home folder.

Still not working.

[MrBobC]

chmod 755 /home/cgmon.tcl

check the settings to see where the log file is pointed to.

Also, did you do the following?

apt-get update
apt-get install tcl
apt-get install php5-cli
apt-get install php5

When I did this for the first time, just php5 wasn't enough, I needed php5-cli.  This is not in the instructions.

[miner777]

chmod 755 /home/cgmon.tcl

check the settings to see where the log file is pointed to.

Also, did you do the following?

apt-get update
apt-get install tcl
apt-get install php5-cli
apt-get install php5

When I did this for the first time, just php5 wasn't enough, I needed php5-cli.  This is not in the instructions.

I did the chmod again.

For the log I have two outputs it seems:
/root/cgmon.log
/live/cow/root/cgmon.log

I just tried to install php5-cli and it showed to already be installed.

Also, for the "user" in the cgmon.tcl file I have it designated "root".  

I can still run the file manually, but cron will not run it. 

[miner777]

Just so this is clear. I check the log after a manual run of the script and its been recorded in the log. I do not see any other runs in the log other then the ones that I have done manually.

[MrBobC]

Do you have "api-listen" : true in your /etc/bamt/cgminer.conf?

[miner777]

Yes.

"api-listen" : true,

[miner777]

I did do this command recommended by Angela earlier in the thread:

set cgminer_gpu_options "-c /etc/bamt/cgminer.conf"

Thats because i would like to be able to set my gpu options via the cgminer.conf file. Not sure if maybe that messed things up.

[MrBobC]

No, I have that too.  That wouldn't impact the ability to just run the monitoring and output the cgmon.log file. That could be it with the root user.  Mine is "user." Try that.  I'm thinking there must be something different between yours and mine.  Your user being "root" could be it.  What version of BAMT are you using?  I use 1.3.

[miner777]

I tried "user" and it did not work. I just now even downloaded a new cgmon.tcl file to the "user" profile. Ran the chmod, and did everything like I am suppose to, pointed the cron to the correct place. Once again it will run manually but will not run with cron. I am using 1.3 SMOS which runs on BAMT.

[miner777]

Something is up with my cron. I tried to start the service with this:
/etc/init.d/cron start


And I get this:
Starting periodic command scheduler: cron failed!

[MrBobC]

Possibly an SMOS issue, though not likely.  Unfortunately friend, I've gone through the list of things I thought it could be, unless there is a problem with syntax somewhere in your /etc/crontab on a different line?

[miner777]

MrBob I appreciate the help. I have put in a call to someone who will hopefully know. If all else fails I will switch out of SMOS and move over to pure BAMT.

Hi,

if I add the following to the end of the cgminer command in cgmon-mine.sh shouldn't it capture the output?

2>> ~/log/_cgminer_log.txt

I want to be able to track whenever a pool failover happens.

This creates the log file but nothing is written to it.

cgmon-mine.sh is created whenever cgmon starts cgminer.  So you actually make that change within cgmon.tcl.  Try adding it to the end of your $cgminer_gpu_options line in cgmon.tcl

Actually the issue is with screen...  When I try logging to a file it only works when NOT using screen...  

You can log cgminer ouput by adding -L to the screen options in cgmon.tcl.

Code:

set screen_cmd "screen -mdL"

Will leave a screenlog.0 file in the current working directory.  Let me know if you find another way to do it.

Has anyone found a free SMTP server to use for email receiving? My ISP's needs authentication..

[jdape]

cgmon 1.0 through 1.0.3 have just been released.

New features:

• SMTP Authentication support! Works with gmail.
• Automatic version check and script updating.   If you run

Code:

./cgmon.tcl update

cgmon will determine if there's a new version available.  If so, it will download the new version and migrate your existing configuration settings into cgmon.tcl.tmp.   Then you can move the temp file to cgmon.tcl.

# 1.0
#   Added auto update procedure:  ./cgmon.tcl update
#   Added SMTP AUTH support.
#   Added screen command syntax to output when starting.
# 1.0.1 & 1.0.2
#   Bug fixes
# 1.0.3
#   Added new version notifications to emails, when applicable.

FYI, to debug SMTP AUTH, change line 480 from:

Code:

			-debug false \

to

Code:

			-debug true \

[bomberb17]

In the file change "Ubuntu: apt-get install libtcl tcl-tls" to "Ubuntu: apt-get install tcllib tcl-tls"
