Monitorare l'uptime in Linux con Uptimed

Uptimed è una utility da riga di comando che ci permette di tenere traccia dell'uptime della nostra distro Linux.

Per installarlo su Arch Linux:

# pacman -Sy uptimed

Su Debian:

# aptitude install uptimed

Una volta installato:

# systemctl start uptimed

# systemctl status uptimed
● uptimed.service - uptime record daemon

feb 25 14:22:56 server-casa systemd[1]: Started uptime record daemon.

Per avere un database di partenza dovete riavviare il pc / server.

Poi vi basterà usare uprecords:

# uprecords
     #               Uptime | System                                     Boot up

Potete anche visualizzare i records in ordine (crescente e descrescente):

# uprecords -b
     #               Uptime | System                                     Boot up
----------------------------+---------------------------------------------------
     1     0 days, 05:22:02 | Linux 4.19.0-8-amd64      Tue Feb 25 09:00:24 2020
->   2     0 days, 00:04:33 | Linux 4.19.0-8-amd64      Tue Feb 25 14:22:47 2020

# uprecords -B
     #               Uptime | System                                     Boot up
----------------------------+---------------------------------------------------
->   1     0 days, 00:04:36 | Linux 4.19.0-8-amd64      Tue Feb 25 14:22:47 2020
     2     0 days, 05:22:02 | Linux 4.19.0-8-amd64      Tue Feb 25 09:00:24 2020

Oppure possiamo visualizzare i periodi di downtime:

# uprecords -d
     #               Uptime |        Last downtime                       Boot up
----------------------------+---------------------------------------------------
     1     0 days, 05:22:02 |     0 days, 00:00:00      Tue Feb 25 09:00:24 2020
->   2     0 days, 00:06:07 |     0 days, 00:00:21      Tue Feb 25 14:22:47 2020
----------------------------+---------------------------------------------------
no1 in     0 days, 05:15:56 | at                        Tue Feb 25 19:44:50 2020
    up     0 days, 05:28:09 | since                     Tue Feb 25 09:00:24 2020
  down     0 days, 00:00:21 | since                     Tue Feb 25 09:00:24 2020
   %up               99.893 | since                     Tue Feb 25 09:00:24 2020

Diciamo che su un server può essere molto utile.

Enjoy!
