SSL/TLS and Session Cache Status Stats

[TheOldMan2000]

Hello Team Netdata,

Is it possible for Netdata to monitor/chart the stats that appear at the bottom of the WHM/Cpanel Apache Status page (WHM Home > Server Status > Apache Status ):

SSL/TLS Session Cache Status:

Hi, @TheOldMan2000. So it is additional info you get from mod_status? The data sample you posted - is it all data you get from "WHM Home > Server Status > Apache Status" or do you show only part related to Session Cache Status?

Anyway, it is easy to implement (update apache collector) if somebody will:

• tell how to set up a local Apache instance with SSLSessionCache.
• tell what metrics are worth collecting.

Hi @ilyam8

Yes I was just showing the relevant bit at the very bottom of the page. It shows up at the bottom if you use a browser to go to the server-status page too, not just a WHM/Cpanel feature.

E.g.

example.com/server-status
example.com/server-status?auto
example.com/server-status.refresh=2

The exact output depends on what you have enabled:

https://httpd.apache.org/docs/current/mod/mod_ssl.html#sslsessioncache
https://httpd.apache.org/docs/current/mod/mod_ssl.html#sslstaplingcache
