Below is my server htop
display. The nginx
process uses CPU time more then 18 hours, and is shown in red color, but CPU and memory all look OK. Is the value within the normal range?
I was curious about this too, so I dug into the source code and found this:
if (hours >= 100) {
snprintf(buffer, 10, "%7lluh ", hours);
RichString_append(str, CRT_colors[LARGE_NUMBER], buffer);
} else {
if (hours) {
snprintf(buffer, 10, "%2lluh", hours);
RichString_append(str, CRT_colors[LARGE_NUMBER], buffer);
snprintf(buffer, 10, "%02d:%02d ", minutes, seconds);
} else {
snprintf(buffer, 10, "%2d:%02d.%02d ", minutes, seconds, hundredths);
}
RichString_append(str, CRT_colors[DEFAULT_COLOR], buffer);
}
So, it looks like whenever the CPU time exceeds one hour, the hour portion is just highlighted in red (or whatever CRT_colors[LARGE_NUMBER]
happens to be.)
Notice that the time format changes as the time goes:
4:33.42
is minutes/seconds/millisconds
18h26:41
is hours/minutes/seconds
101h
would be hours > 100
