Deployment to some machines are slower than others with listening tentacle

Hi
we are deployment to multiples VMs in Azure using listening mode on the tentacles. They all succeed, however one machine’s deployment consistently takes 5 mins longer than the others, if not more. We are in a live PROD environment, and we need to keep our downtime to a minimum.

All tentacles are running version 3.4.4. with latest calamari 3.4.1. They are connecting over https using port 10933.

Can you help me get understand the issue?

thanks in advance

Hi @Csmyth,

Thanks for reaching out! Lots of things could be happening in this scenario. Off the top of my head I can think on:

  • Different OS patching compared to the other machines.
  • Powershell modules that might be installed only on that machine that might be making each PS session opened during the deployment to perform slower.
  • Differen disk I/O speed than the other machines.
    all of this assuming this machine has the same hardware ,network configuration and Tentacle/Calamari version as the rest of the machines in the farm of course

All of those reasons point to an environmental thing that might be happening only on that machine. Personally, I would take advantage of the power of the cloud, re-build that machine from a clean image and see if the error persists.

Now If you wanna jump to troubleshoot this particular machine, then the first good step would be to send us a raw deployment log where we can see which particular step is taking longer on that machine.

Best regards,
Dalmiro
