Hi guys,
I currently trying to debug a similar issue. I am also getting EOF only as
error in debug level from scrape manager. I had the same issue locally with
curl and LibreSSL on macOS. Updating the curl version to use openSSL fixed
it. So my assumption it's something related to SSL/TLS. My working curl
verbose output gives me this in regards to TLS:
* ALPN: offers h2
* ALPN: offers http/1.1
} [5 bytes data]
* TLSv1.3 (OUT), TLS handshake, Client hello (1):
} [512 bytes data]
* TLSv1.3 (IN), TLS handshake, Server hello (2):
{ [193 bytes data]
* TLSv1.3 (OUT), TLS change cipher, Change cipher spec (1):
} [1 bytes data]
* TLSv1.3 (OUT), TLS handshake, Client hello (1):
} [512 bytes data]
* TLSv1.3 (IN), TLS handshake, Server hello (2):
{ [155 bytes data]
* TLSv1.3 (IN), TLS handshake, Encrypted Extensions (8):
{ [51 bytes data]
* TLSv1.3 (IN), TLS handshake, Certificate (11):
{ [4943 bytes data]
* TLSv1.3 (IN), TLS handshake, CERT verify (15):
{ [520 bytes data]
* TLSv1.3 (IN), TLS handshake, Finished (20):
{ [52 bytes data]
* TLSv1.3 (OUT), TLS handshake, Finished (20):
} [52 bytes data]
* SSL connection using TLSv1.3 / TLS_AES_256_GCM_SHA384
* ALPN: server accepted h2
but HOW do I get more info from Prometheus?
Thx,
Markus
