| Indicações de uso de RAM pelo Conky e pelo htop, em 2019 |
- Este registro é um trecho retirado de “Ferramentas mudam cálculo de Memória RAM”, por ser extenso demais.
Conky e htop usavam o mesmo cálculo de uso de Memória RAM, entre 2017 (pelo menos) e 2020 — com pequenas diferenças no openSUSE Leap, em certa época:
Nearly:
Mem used = MemTotal - [MemFree + Active(file) + Inactive(file) + SReclaimable]
from:
$ cat /proc/meminfo | grep 'Mem\|Active\|Inactive\|Reclaimable'
MemTotal: 16222988 kB
MemFree: 10472736 kB
MemAvailable: 12730508 kB
Active: 3229096 kB
Inactive: 1359400 kB
Active(anon): 2327472 kB
Inactive(anon): 0 kB
Active(file): 901624 kB
Inactive(file): 1359400 kB
KReclaimable: 337196 kB
SReclaimable: 337196 kBFoto (acima) - Uma experiência simples, em Janeiro 2019, mostrava essa paridade de cálculo entre o Conky e o htop — bem como a diferença de cálculo do free e do top (do pacote procps):
RAM Used Free Buffer Cache Buff/Cache Available (used Swap)
Conky 2.4 GiB 828 MiB 101 MiB 794 MiB 1.43 GiB 278 MiB
htop 2.4 GiB 278 MiB
top 2150 MiB 830 MiB 944 MiB 1243 MiB 278 MiB
free 2.1 GiB 829 MiB 943 MiB 1.2 GiB 277 MiB
Mas eu já tinha percebido isso desde 2017 (pelo menos), quando uma série de verificações me mostrou uma convergência quase perfeita entre as medidas do Conky e as do htop — com pequenas diferenças, talvez porque, na época, não lembrei de igualar o ciclo do htop (2 segundos) ao ciclo do Conky (1 segundo).
Ao revisar agora aqueles registros de 2017, vejo que no openSUSE Leap havia uma estranha divergência entre o Conky e o htop:

Essa estranheza do Conky no openSUSE Leap ficou mais evidente ao levantar o histórico de atualizações das várias distros, de 2016 até o início de 2020, — e constatar que o Leap, sozinho, teve mais versões e revisões do Conky, do que a soma de todas as outras distros, incluindo as rolling-release. — Muitas vezes, o Conky era o único pacote a ser atualizado no Leap:

Como se vê (acima), só nos 8 meses que vão de Outubro 2017 até Junho 2018, o openSUSE Leap apresentou nada menos que 44 atualizações ou revisões do Conky, — praticamente 1 a cada 5 dias, — como se houvesse uma tentativa incessante de corrigir alguma coisa, sem sucesso.
Para uma comparação: — Em 2020, no openSUSE Tumbleweed, às vezes passam-se meses sem atualização do Conky.
