Beberapa waktu yang lalu, kami membahas cara menemukan waktu aktif sistem Linux menggunakan Tuptime utilitas di Linux. Hari ini, kita akan mempelajari tentang utilitas serupa bernama Uptimed . Ini adalah utilitas baris perintah yang digunakan untuk merekam dan melacak waktu sistem Linux. Menggunakan Uptimed, kita dapat dengan mudah menampilkan ringkasan catatan uptime historis, seperti berapa lama sistem Linux Anda telah menyala, berapa uptime tertinggi, kapan sistem telah di-boot ulang, dll. Dalam panduan singkat ini, mari kita lihat cara memantau Uptime sistem Linux menggunakan utilitas Uptimed.
Instal Uptimed Di Linux
Uptimed tersedia di repositori resmi sistem operasi Linux populer.
Untuk menginstal Uptimed di Linux Arch , cukup jalankan:
$ sudo pacman -S uptimed
Di Debian , Ubuntu , Linux Mint :
$ sudo apt-get install uptimed
Harap dicatat bahwa di Ubuntu dan turunannya, pastikan diaktifkan [universe] penyimpanan.
$ sudo add-apt-repository universe
Di Fedora :
$ sudo dnf install uptimed
Di CentOS 7 :
Uptimed tidak tersedia di repositori default CentOS. Jadi, Anda perlu mengaktifkan repositori EPEL untuk menginstalnya.
Aktifkan repositori EPEL:
$ sudo yum install epel-release
Dan kemudian instal Uptimed menggunakan perintah:
$ sudo yum install uptimed
Pada sistem Linux lainnya, unduh Uptimed dari laman rilis lalu kompilasi dan instal secara manual.
# wget https://github.com/rpodgorny/uptimed/archive/v0.4.2.zip -O uptimed.zip
# unzip uptimed.zip
# cd uptimed-0.4.2/
# ./configure
# make
# make install
Setelah menginstal Uptimed, aktifkan dan mulai layanan uptimed:
# systemctl enable uptimed
# systemctl start uptimed
Periksa status layanan uptime:
# systemctl status uptimed

Untuk memantau waktu aktif sistem Linux antara reboot sistem, cukup jalankan:
# uprecords
Contoh keluaran:
# Uptime | System Boot up
----------------------------+---------------------------------------------------
1 0 days, 02:35:51 | Linux 3.10.0-1062.1.1.el Tue Feb 11 14:22:33 2020

Di sini, tanda panah di kolom pertama menunjukkan waktu aktif terbaru.
Urutkan hasil berdasarkan waktu boot
Untuk menampilkan waktu aktif sistem Linux Anda yang diurutkan berdasarkan waktu boot, gunakan -b bendera:
# uprecords -b
# Uptime | System Boot up
----------------------------+---------------------------------------------------
1 0 days, 00:07:27 | Linux 3.10.0-1062.1.1.el Tue Feb 11 14:13:59 2020
2 0 days, 02:35:51 | Linux 3.10.0-1062.1.1.el Tue Feb 11 14:22:33 2020
-> 3 0 days, 00:30:14 | Linux 3.10.0-1062.1.1.el Tue Feb 11 17:02:29 2020 Demikian pula, untuk membalikkan pengurutan berdasarkan waktu boot (yaitu hanya menampilkan reboot terbaru), gunakan -B bendera:
# uprecords -B
# Uptime | System Boot up
----------------------------+---------------------------------------------------
-> 1 0 days, 00:14:51 | Linux 3.10.0-1062.1.1.el Tue Feb 11 17:02:29 2020
2 0 days, 02:35:51 | Linux 3.10.0-1062.1.1.el Tue Feb 11 14:22:33 2020
3 0 days, 00:07:27 | Linux 3.10.0-1062.1.1.el Tue Feb 11 14:13:59 2020 Menampilkan X jumlah waktu aktif
Saat menjalankan perintah uprecords tanpa opsi apa pun, ini akan menampilkan ringkasan 10 catatan uptime historis teratas secara default. Namun, Anda dapat mengubahnya menggunakan -m bendera. Misalnya, perintah berikut akan menampilkan 20 record teratas:
# uprecords -m 20
Jangan potong keluaran
Seperti yang Anda perhatikan pada output di atas, informasi versi kernel Linux di sistem kolom telah terpotong (yaitu Linux 3.10.0-1062.1.1.el). Jika Anda tidak ingin memotong informasi, gunakan -w bendera (keluaran lebar).
# uprecords -w
# Uptime | System Boot up
----------------------------+---------------------------------------------------

Anda juga dapat menampilkan waktu henti antara reboot alih-alih versi kernel menggunakan -d tandai seperti di bawah ini:
# uprecords -d
# Uptime | Last downtime Boot up
