You can setup ansible to scrape the data every x seconds or whatever. Its one external way to pull info.
The reality is the logs are pretty useless. The machines dont reboot on their own, if you think they are then its most likely your power supply dropping out.

The temps sensors are chip level, there is nothing you can do that will revive it, so I wouldnt bother taking it apart and risking damage for nothing.

Your temps are very low, you have nothing at all to worry about. These things dont even shut off until you have passed 110 degrees chip temperature.
I wouldnt begin worrying about heat until you hit 100 on the chips.
As far as reducing flow, how are you doing it? If you are reducing it improperly and creating a bunch of drag you will kill your fans quicker.
Running your fan at 6000 rpm is fine, that is what they are built for.

They will go back to mining if the outage is short lived. If your internet is going out for 15-20 minutes or more, there best solution is running management software that will auto reboot miners that are not hashing.

Really the designs are quite simple. You can mount the electrical on the outside of the container and on the inside you just have to distribute power to racks and install some exhaust fans. In a space that small a passive intake with enough exhaust to pull through should be fine. What you need on that front depends on how power dense you are trying to go on the inside.

So even doing the IP reporter hard factory reset did not bring it back to factory settings?

Bitmains power supplies are just garbage. I have no cold start problems using higher end server PSUs. I have started my miners (s7, s9, e9, and Avalon 741s) around 0c before. They will not run at full speed until they warm up, but other than that you shouldnt have many problems if 5c is the lowest temp you will see.

Are you seriously asking why would someone buy these miners rather than Bitmain? Let me give a couple of reasons:
- Because buying miners from Jihan Wu is like supporting your enemy. The guy is doing everything he can to destroy the coin you want to mine - BTC
- Because you can not buy Bitmain with BTC. True story, go check their site. Only altcoins accepted. Trading BTC for shitcoins to buy a miner also undermines your currency.
- Because Bitmain has cornered the market, in periods when mining is with real ROI he mines with newly produced miners, when it is not he is selling them to you. Once this monopoly is broken, hopefully by DragonMint and some others, you may have a chance to buy a miner when it's profitable to mine
Everyone blames the one successful hardware company in the space because they are successful. 1. His companies miners are what run the BTC network. You claim he is the enemy but do you even know anything about him other than what biased people say about him to further their agenda? Please show me what actual destruction he has brought to the ecosystem that would be nothing without his company. 2. Converting bitcoin to something else doesnt destroy or undermine it in any way. Trading in or out of bitcoin adds to its market volume and shows that it is a store of value people want and have been using. 3. Its absolutely his companies right to mine on their own hardware. They spent the money to design, build, and test it. Guess what? Even the s7 is still a profitable machine, so how can you claim you dont have a chance to buy a miner that is profitable? If you bought an s7 new, you have made thousands and thousands of dollars in BTC from it. There is no other investment with as short of an ROI as bitcoin miners.....yet people are still unhappy. |

What do GPU stats have to do with bitcoin speculation?

You cant mine without an ASIC device. What hardware are you trying to mine with? If you are just doing it with your CPU you should stop now.

This antminer would generate 0.07840525 btc/month according to calculations, is this correct? I find it insane. Next halving will be in 2020, right? A friend of mine told me that bitcoin developers "will change" bitcoin in order to shutdown asic mining. Is this correct? Happy mining  Yes at current prices an Antminer S9 makes over $700/mo not counting electricity. Your friend is very wrong about bitcoin developers changing anything relating to its algorithm. Bitcoin will be asic mined long into the future. |

If you share the same circuit as your range you will pop that circuit every time you try and cook something with miners running. You need to put the mienrs on their own separate circuit.

What exactly are you trying to do? Multipool mining with bitcoin died a long time ago, its not even supported by current generation miners.

What kind of firewall do you recommend? Thanks.
pfsense will probably give you the most bang for your buck as long as you know how to configure it |

You have to step it down from 600V to 208/120V 3phase then distribute it to single phase circuits in able to power up that psu.
You can always just use 3 phase PDUs and not worry about that last step. |

A lot of it depends on how the warehouse is already setup.
If the warehouse was ever used for industrial equipment I would think they already have 3 phase 480v coming into the building. You would hopefully just need a 500kva 480 to 208 transformer for what you want to do.
What you want to do is hire an electrical contractor to look over what you have available. They will be able to give you a clearer idea of what is involved. You arent asking for much power, so it shouldnt be too hard to get.

They affraid coz you can clone whole operation system, by the way you can do this even without having SSH password;)
I think whole system run from SD card inside miner.
Anybody know what OS running on ebit e9+ miner???
Cloning a system you cant get into to make changes is pretty pointless. BTW there is no SD card in the ebit, they have an embedded controller very similar to the S9. It runs linux, just like all the other miners. Most likely based on BusyBox. |

Lets refrain from calling stuff junk when you have no idea how crypto or the community in general works, and said community keeps the price where it is so you can mine with your expensive miners and make profit.
Most people don't have thousands to spend like you, or know nothing about mining and crypto in general to spend said thousands. This is a great way to get into it.
You can thank me for bringing thousands of new people into LTC, and support the price YOU mine at. Think twice before calling any of this junk or stupid.
What have you done to support LTC and the community in general?
I can thank you for profiting on people that dont know better by selling them equipment that has a coin flip chance at best of ever reaching break even? If people want one or two of them so they can pat themselves on the back and say that they are mining thats fine. I was referring to people that were buying large quantities and trying to run them with a really expensive hub like the one I quoted when making my post. If you are going to invest that kind of money there is literally no reason to spend all that money versus buying a high end miner. |

This makes my brain hurt. $60 USB stick that makes $3/month. $165 hub to run them. 20 Sticks = $1200 USB hub = $165 Monthly Profit $60 You are looking at a 2 year ROI if LTC price keeps rising a bunch. Or For a similar investment you can buy an L3+ and ROI in 4 months Why would anyone buy this junk? |
