Comment:

 this is a problem again: running out of space on nbg1.

 the database is now at 63.2 GB. we have metrics since 2019-09-20, which
 makes 234 days today. we have 78 hosts in LDAP, with a scrape interval of
 1 minute, so this makes for about 2000 samples (not 1300 as originally
 guessed):

 {{{
 > 234d×1.3byte/(1min)×2000×78 to Gibyte
 63,642383 gibibytes
 }}}

 we'd need 100GB to cover a year:

 {{{
 > 365d×1.3byte/(1min)×2000×78 to Gibyte
 99,271238 gibibytes
 }}}

 i'll see if i can resize the server again this week.
