# Monitor ![Monitor Screenshot](../../images/cryptominer_monitor.png) ## Monitor your GPUs Your mining rig is working hard to make you money. Time is money, and any downtime delays your ROI. Non-working GPUs are therefore costing you money. It's important therefor to monitor and chart your GPUs performance. I wrote a [script](https://gist.github.com/funkypenguin/456f2b960b62409f1e977df695c62a23), which I use with Icinga/Nagios, to alert me if any of my GPUs are misbehaving. !!! tip I share (_with my [patreon patrons](https://www.patreon.com/funkypenguin)_) a private "_premix_" git repository, which includes up-to-date copies of all supporting scripts and tools I produce, meaning patrons just run a "git pull" and they're ready to go! 👍 I use NRPE to execute the GPU-testing script, from my Icinga host (_hopefully a future recipe will cover Icinga_), with a config something like this: ``` # monitor_gpu dont_blame_nrpe=1 command[check_gpu]=/usr/bin/sudo /opt/minerhotel/scripts/monitor-gpu.sh $ARG1$ $ARG2$ ``` And the following to sudoers: ``` nrpe ALL= NOPASSWD: /opt/minerhotel/scripts/monitor-gpu.sh * ``` ## Monitor your empire So you're mining coins.
