I see this too. I am presuming it is a retry before first attempt completed as it takes a long time?

[laizhimingong]

Yes, I have encountered this situation many times recently, and the error reports are consistent

Also seeing this, my scrapes usually take under 30s but every now and again it seems like it just randomly times out (scrape interval 1m, timeout 1m), and I see a lot of this error in the logs.

Graph for reference:

I also see the same error in the logs. Has anyone found a workaround?

i moved to this: https://github.com/cblomart/vsphere-graphite instead. More tunable and doesn't reset everytime endpoint is hit for metrics. Seems like this project struggles with big environments.
