I already found my answer in documentation. What I did not found though is how many metrics are collected by Netdata by default
#How long does Netdata sore metrics?

I already found out 😄 It shows 377 charts. Sorry for false alarm.

@amber viper hey it very depends - from several thousand to tens of thousands. You can check the number using /api/v2/info endpoint
Look for db_size -> currently_collected_metrics
amber viper
Oh that is great info
cedar tiger
For instance, I have 18K on one of my Proxmox server (it has a lot of VMs)
amber viper
That is some great advice. I am very grateful to you!

db_size -> currently_collected_metrics includes children metrics on a parent instance.
This is stats from the parent ND in our lab we use to test things
"db_size":[{
"tier":0,
"disk_used":4163017324,
"disk_max":4294967296,
"disk_percent":96.9278003,

"to":1691749564,
"retention":225204,

}],
currently_collected_metric 1.3 Million (this parent has 250+ children)

I see now. I wonder why the retention times are negative with us
"db_size": [
{
"tier": 0,
"disk_used": 2838528,
"disk_max": 8589934592,
"disk_percent": 0.0330448,
"from": 9223372036854775807,
"to": 1691751436,
"retention": -9223372035163024371,
"expected_retention": -9223372036854775808,
"currently_collected_metrics": 9122
}

Looks like a bug with first_time_s ("from"), I reported it.
What is your Netdata version?
show netdata -W buildinfo
cedar tiger
I need this info to open a bug report

Oh. I am already out of office. I will write to you on Monday. Thanks for your assistance!
