About missed slots

I have this metric in prometheus and really don’t understand what it means or if its a problem or not.
Can somebody clarify what’s the missed slots and how can be fixed?

Hi!

Have you checked these topics?

sure looks like we can’t lose blocks because of this, I’ll try to ignore by now

Could give it a try to calculate your network delay, I would be curious what is the value for your BP node…

I’ve been experiencing some missed slots too but i’ve notice it only happens after the end of ever block and the beginning of a new one.

you mean epoch? are you running 1.26.2 version of cardano-node?

sorry yes epoch. And yes I’m running 1.26.2

can you give it a try calculate what is the delay of your network?

how can I do that? glview won’t display RTT more than a few ms

ok - I post it again:

Here is a sample of the delay I got using your post.

2021-05-05 12:44:12.53 UTC’
2021-05-05 12:44:18.23 UTC’
2021-05-05 12:44:48.29 UTC’
2021-05-05 12:44:53.27 UTC’
2021-05-05 12:45:08.34 UTC’
2021-05-05 12:45:11.30 UTC’
2021-05-05 12:45:13.08 UTC’
2021-05-05 12:45:25.27 UTC’
2021-05-05 12:45:35.14 UTC’

Will dm you, since this is not the desired output of the command…

sorry I cannot execute any of these commands are they broken?

will dm you - should work…

yes, that is json format… I will update the script to handle that format, and get back to you
